An overview about RO water purifiers

Posted on September 24, 2012 by admin

It’s been scientifically proven that 60% of the human body is made up of water. Add to that the fact that a person needs a minimum quantity of 3 liters consumption of water per day in order to keep oneself fit. These two just go on to prove the essentiality of water for us humans. It can also be considered as one of the basic necessities i.e. food, clothing and shelter and water undoubtedly forms a part of the food component as it is a necessary element required for proper digestion of the food consumed by any person.  So, it can indisputably be deduced that without water a person would be in peril.

With the increasing population and pollution, the necessity and need for the hour, in any area of the world is more of getting hold of required amounts of water, and more so getting pure water, than just water itself. Industrial wastes, wastes from households and many other polluting elements are present in all sorts of water ranging from water for bathing, washing and even drinking water in alarming and life threatening levels.

What is a person to do under such circumstances? There is only but one solution for this problem. Getting a water purifier in order to ensure that the water one is consuming is potable, safe and will not lead to any negative consequences to his health. For this, one needs to first understand the types of purifiers available in the market, what exactly it is and how it works. By the end of this article, you’ll have a fair knowledge about the functioning and working of a simple RO purifier.

Let us first look at the basics.

What is this Reverse Osmosis?

Reverse Osmosis works on a similar theory as osmosis, but in the reverse route, wherein, external pressure (as opposed to internal pressure in osmosis) is used on the sect enclosing salty solution, then pure water is enforced out of the cell and the salt is preserved. As the water is removed from the salty solution, the concentration of the water increases along with the osmotic pressure. This process goes on till the osmotic pressure value of the left over salt solution inside the cell matches with the external pressure used.

Reverse osmosis membranes also restrain suspended contamination; such as, silt, colloidal particles and microorganisms by asset of their ultra-fine pore size. Thus, reverse osmosis membranes hold back all kinds of impurities.

How does the RO system work?

It involves a method in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is achieved by domestic water pressure pushed through the tap water via a semi permeable membrane. The membrane (about the same thickness as an average cell phone) permits only the water to flow by, not the dirt or impurities. These go down the drain.

What influences the performance of the water purifier?

  • Pressure of water
  • Water Temperature
  • Kind and number of total dissolved solids (TDS) contained  in the water
  • The type and quality of filters and membranes attached for use in the RO System.

What are the basic components of any RO purifier? (Must be checked before zeroing in on the purchase)

  • Cold Water Line Valve
  • Pre-Filter (s)
  • Reverse Osmosis Membrane
  • Post filter (s)
  • Automatic Shut Off Valve (SOV
  • Check Valve
  • Flow Restrictor
  • Storage Tank
  • Faucet &
  • The Drain Line

Is 100% purification guaranteed?

No. None of the RO purifiers, be it any brand or company,  can guarantee a 100% purification (even if it claims so), as like any other scientific process, this has limited effectiveness .Reverse osmosis will eliminate up to 96-99% of basic ions, and 99.5+% of all other contaminations.

And, the most important of all.

Why RO?

You first need to make your mind up your mind about whether you want to go for a UV based purifier or an RO based purifier. Research indicates that UV purifiers can eliminate bacteria and viruses but not additional contaminants like nitrates, arsenic, fluorides, mercury etc., Moreover, UV filters would not lessen the quantity of total dissolved solid (TDS) in the water.  The rational and prudent decision here would be to opt for an RO purifier as it would ensure increased levels of purity in the water in comparison to a UV purifier. As, reverse osmosis membranes hold back all kinds of impurities, it is the ideal choice as a water purifier.

To know about how to get the best water purifier, you will have to familiarize yourself with the various techniques involved as well as the methods. Once you know about the nuances of the functioning of the systems, components used, etc. you will be able to choose the right and the best water purifier. To collect information about the same as well as to know about the various available brands, just go online. You will come across a wealth of information materials. Do not miss the comments and reviews posted by users in various water forums. Users post real experiences both positive and negative about the home water purifier systems they use. You will then be able to choose the brand as well. 

Do not just blindly buy a home water purifier only because it is the best water purifier based on your survey. You should first get the water you receive tested. You can also come across water testing labs. Once you get the water tested you will know which home water purifier, i.e. whether you need reverse osmosis or UV water purifier or some other system or blends.

The UV water purifier is used at homes where water received in the tap or any source and full of micro organisms. Most of these micro organisms cause water borne diseases that may play havoc on your health. And if you drink such water regularly without getting it purified, you will nurture diseases that will prove dangerous for you in the long run. The UV  outfitted in the UV water purifier operates deactivating all micro organisms. Go for such a system with multi-purifying techniques involved. It is the need of the hour to protect your health against water born diseases by drinking only purified water.

RO Systems Basics

Posted on May 28, 2012 by admin

Reverse Osmosis: What is it?

  • RO is a form of filtration using osmosis in reverse
  • Water passes from a more concentrated solution to a less concentrated solution
  • To accomplish this a force or pressure MUST be applied
  • RO requires 1 psi of pressure for every 100 ppm of TDS
  • RO is used to remove dissolved solids from water but it can also improve taste, odor & color of water
  • RO membranes have the capability to remove particles as small as ions i.e. magnesium ions or sodium ions
  • RO membrane will reject most compounds based largely on size
  • Dissolved ions, such as salts, carry an electric charge and will also be rejected by membrane

Reverse Osmosis: How does it work?

  • Feed water flows into RO unit with the force of line pressure
  • Water is forced through membrane by cross flow filtration
  • Cross flow filtration is most commonly used in RO as it allows membrane to continually clean itself
  • Membrane then either rejects or repels contaminants
  • Two exit streams generated: waste & product stream
  • Waste stream consists of: A concentrate (reject) stream which carries contaminants (compounds too large to pass through membrane)
  • Permeate stream consists of: Product water which has been forced through the membrane & is virtually free of TDS

Parameters that affect RO:

Water Temperature: RO system ratings are based on 770F/ 250C water temperature

i.e. : RO system rated at 20 GPD (gallons per day) at 340F/10C will only produce 6 GPD

Feed Water Pressure: A lack in water pressure (less than 40 PSI) will reduce product water; this can be helped with the aid of a booster pump

Contaminants in Feed Water: Large particles, iron concentration or high levels of hardness in feed water can cause clogging of the membrane. Clogging of the membrane can decrease its life

Microorganisms: RO membranes can filter out bacteria, depending on the bacteria size, however this may cause fouling of the membrane as bacteria can begin to grow through pores of membrane causing BACTERIA CREEP – RO systems should not be installed on non-potable water

Marvelous Features of Hi-tech RO Water Purifiers

Posted on April 26, 2012 by admin

So, you have read about the benefits of using RO water purifiers. You have read about this purification mechanism after getting your water tested in the nearest lab and you have been recommended of using a reverse osmosis filter system.

It is not only the information material but also reviews and comments that have let you know about the best brand and variants of RO water purifiers available in the market or via direct sales. This is exactly what a wise consumer does before buying a product, especially a home consumer durable product. And when it comes to water purifiers, more effort and time is put because health cannot be compromised. With 80% of the diseases in the world being water borne, it is a must to drink water that is purified in advanced water purifiers involving the right mechanism.

When you buy a reverse osmosis filtration system, do consider the storage capacity as well. For a small family a low storage will do and vice versa. Most RO water purifiers that are a bit high on the budget come with advantageous features such as:

  • Multi-stage filtration with the use of multiple cartridges in addition to RO membrane
  • Micro switch float feature to stop over flow of water
  • Auto shut off mechanism, thus saving energy for you
  • Manual flush facility, cleaning the cartridge and enhancing its life
  • Post taste enhancer for reviving the original taste of water
  • TDS reduction to maximum percentage and TDS support facility
  • Ease of cleaning the storage tank totally from inside from time to time
  • Facility for elimination of tough new-age contaminants.

Of course, there are downsides associated with the reverse osmosis filtration mechanism. But for every purification mechanism, there are both pros and cons. So, it is advisable to go for the highly hi-tech reverse osmosis filtration system of a reputed brand; in such a system, the cons are reduced compared to those that come with simple RO mechanisms.

The biggest downside of using a reverse osmosis filtration system is the amount of water wasted during the filtering process besides the time it takes to purify water. But even that makes sense if your water is high in TDS content. Only the use of such a mechanism will prove effective to ensure that you consume only 100% safe and pure water.

What is a Reverse Osmosis Water System?

Posted on March 29, 2012 by admin

This is the finest filtration available today. It is the treatment typically used by premium bottled water companies.

A very wide array of contaminants are eliminated or substantially reduced.

For residential or cottage applications, it has the greatest range of contaminant removal.

Reverse osmosis water systems filter particles through a membrane which is approximately 0.0005 micron in size (bacteria are 0.2 to 1 micron & viruses are 0.02 to 0.4 microns).

These units remove substantial amounts of salts, metals, minerals and most microorganisms including cryptosporidium and giardia, and many inorganic contaminants.

These systems also successfully treat water with dissolved minerals and metals such as aluminum, arsenic, barium, cadmium, chloride, chromium, copper, fluoride, magnesium, iron, lead, manganese, mercury, nitrate, selenium, silver, sulphate, and zinc.

It is also removes many taste, color, odour-producing chemicals, particulates, total dissolved solids, turbidity, and radium. There are two types of Reverse Osmosis Water System membranes typically used in home or cottage water purification systems:

1. Thin Film Composite (TFC)

2. Cellulose Triacetate (CTA).

TFC membranes will filter out considerably more contaminants than a CTA membrane however, they are more susceptible to degradation by chlorine.

Are you are considering a RO system on a chlorinated water supply? It is important that it include quality activated carbon pre-filters to avoid this degradation.

A typical RO system is composed of first, activated carbon (GAC) pre-filters, the RO membrane, a storage tank, and a faucet to deliver the purified water to your counter top.

Look For Quality- the Best Water Filter

Please note that RO systems vary in membrane quality, output capacity, and storage capacity.

The effectiveness of a system depends on the quality of its components – especially its pre-filter cartridges and the membrane itself.

Lower quality pre-filters will suffer from premature membrane fouling, reduced performance, lower purified water output, and a shorter membrane life.

RO Water Purifier System

Posted on March 16, 2012 by admin

RO Water System

Most people today feel safe that the water they are using for drinking is safe. This may be true for people that obtain their water source from their Municipality. However, the water received is not 100% guaranteed to be clean. People using water from private sources such as wells are at an even higher risk of drinking contaminated and unsafe water.RO Water System units are used to filter and flush away contaminants in the water.

How do RO Water Systems Work?
The water purification process of Reverse Osmosis is done by forcing water through a plastic membrane. The membrane is small and only allows water molecules to pass through. Larger compounds that may be found in the water are rejected and do not continue through the system. After the water has passed through the membrane, it then goes through a special filter. The filter is made to get rid of dangerous chemicals such as; chlorine, mercury, copper, chromium, and even pesticides. When the water has been filtered it is then stored in a water tank until it is ready for use. The water will go through a carbon filter just before use to enhance the waters’ taste.

What are RO Systems Used For?
Although Reverse Osmosis water systems are used to purify water, it is necessary that the water is first evaluated. Water sources such as wells need to be tested for other types of water contaminants such as microorganisms. Once it has been proven that the water is safe to drink you can further enhance the quality and safeness of the water by using a RO Water System. Like many other water filtering systems, Reverse Osmosis is great for purifying untreated sources of water, but is not completely effective against microbiological contamination.

Benefits of Using RO Water System
RO water systems are a lot more efficient when compared to other water filtrating systems. An approximate 3 gallons are used to obtain 1 gallon of purified water with Reverse Osmosis. This type of water filtration allows water in your home to be mineral-free. As most of us know, certain minerals can be harmful to our health. Untreated water commonly contains minerals such as; lead, manganese, salt, calcium, and iron. Minerals are not the only hazard; chemicals such as fluoride are also often found in untreated water.

Choosing the Right RO Water System
One important thing to consider when purchasing a RO system is selecting between a CTA or TFC unit. A cellulose triacetate membrane (CTA) uses an organic membrane that is more susceptible to bacterial growth. The thin film composite (TFC) is made from inorganic material and is not prone to growing bacteria. While there are many more types of RO systems to choose from, CTA and TFC units are among the more common ones. Another thing to remember while looking for the ideal RO system is if you want one that includes a tank. Tanks are used for storing filtered water, but can take up a lot of room and run a bit slower. Systems without tanks usually work at a faster speed and are more compact. Lastly, do not forget to search for a system that is efficient. Some units only purify 1 gallon of water per every 6 gallons used. This makes the efficiency rate less than 15%. Ideally, each gallon should only use 2-4 gallons of unpurified water.

Commercial RO, types of commercial RO and their use

Posted on December 26, 2011 by admin
Membranes are a selective barrier used in anything. The idea of membranes has been derived from the biological cell membrane. It is an artificial polymeric barrier used to stop any kind of dust or dirt from getting further deep into any kind of system.

RO means Reverse Osmosis. Reverse osmosis is a method of filtration. This filtration system removes any kind of big molecules by applying pressure on one side of the membrane. The use of the RO system is applied in filtering the water in the following forms:

  • Drinking water
  • Boiler feed water
  • Sea water
  • Desalination
  • Ultra pure water
  • USP water
  • Water reuse
  • Brackish water
  • High flow commercial application
Reverse Osmosis system is the most effective system for any kind of cleaning of water. The basic filtering media is the RO membrane.

How does an RO membrane work?

The RO membrane is a membrane that is a form of a filter in general terms. The pore sizes of its elements can be between 0.1 to 5,000 nanometers (nm). The size depends upon the component being filtered from the water. The smallest filter can restrict minerals and salts to pass through the membrane and purify the water through a pressure system. The pressure system works by applying pressure to the water which forces the water to gush through the membrane which in the process purifies it and cleans the water. The membrane systems are strong enough to filter different bacterias and germs from the water as well.

The commercial RO membranes are available in the following forms:

  • Tap water RO membranes: This is used for small usage systems. Like small commercial water usage, this system is able to purify less than one gallon of water in a minute.
  • Brackish water RO membranes: This kind of system is used for light industrial systems. It needs high rejection and operating pressures as low as 200 psig.
  • Low energy RO membranes: This kind has the most usage that is used for high purity water.
  • High flow rate RO membranes: These are used for medical places. Lots of pure water is required in hospitals, dialysis clinics.
  • Nano RO membranes: They pass monovalent salts through the RO membrane and remove organics with molecular weights greater than 300 amu.
  • Sea water RO membranes: This kind of RO membranes are the best and very high in quality as they clear all kind of salts in the sea water and desalinate it completely for easy drinkable human use.
The life of a commercial RO membrane:

Normally the life expectancy of any RO membrane is about 2years. After 2 years or maybe a little more or less they loose their way of purifying completely. They should be changed by the time they loose their life so that the water purification system stays. The water after purification gets clean and leaves behind a whole mass of different particles like oil, silica, clay, iron, sulfur and acids.

RO SYSTEM (Reverse Osmosis Water System)

Posted on December 26, 2011 by admin
RO means Reverse Osmosis. It is a process that is used for water filtration. The impurities of water are cleaned and filtered through the machinery used in the RO system and bring it in drinkable form. The RO system works so well that it can clear all kind of impurities including bacteria and minerals and other such particles that cause water contamination. The RO system is used also to filter acids, chemicals, gases and several other liquid items. 

The working of the RO system:

The RO system works with the help of a membrane. The membrane is used to separate all kind of particles and other materials which reduce concentration materials between different solutions.

A high pressure pump is fit in the machinery that purifies water. The machinery has two tanks that are used for holding water. The first tank holds the contaminated water to which full pressure is applied by the machine and forcing it to pass through the membrane into the second tank. Due to the forceful passing through the membrane; all kinds of particles and molecules contaminating the water remain in the membrane leaving the water completely pure. This clean and pure water is drinkable for humans.

The duty of the RO system:

The reverse osmosis system works for long hours without exhausting. It is used in industries and factories on large and small scale. It is needed to clean all kind of impurities and other ions from the water. The membrane that does the main work of cleaning the water lasts for about two years.

The reverse osmosis system plants are available with capacities that go from 25 GDP to 500,000 GDP. It cleans the feed water also which has the capacity of TDS water capacity of 1000 ppm to 5000 ppm.
The RO systems is highly used in Municipalities for the common public use. It is very important to provide clean and healthy water for drinking purpose to people. This water is used for the following things:

  • Micro electronics
  • Food
  • Beverages
  • Power
  • Marines
  • Pharmaceutical facilities
Company designs:

Most companies design Reverse Osmosis systems that are low in cost and high in producing the best results. The filters are designed in such a way that the system is complete with all kinds of pipes and fitting material. The plant also includes a complete manual that helps in fitting the whole ting easily.

The plants include:

  • Membrane elements
  • Valves
  • Filters
  • Pumps
  • Nano filtration equipment
  • Ultra filtration equipment
  • Fitting manual
The RO systems have all the sense of draining only those components that are impure. The things that are used for the cleaning of the water are not strained by their membrane. The membrane does not filter chlorine and other such things that are added to water for making it pure.

The RO system has smaller plants that can be fitted in homes. The residential plants are quite small and quite adjustable to all kind of domestic designs.
