Reverse Osmosis Water Filter System

Reverse osmosis is the process of purification of water, in which the liquid is passed through a semi permeable membrane containing pores. The pores will allow molecules smaller than their size to pass through them and purify drinking water. A water filter system using reverse osmosis is used to desalinate water. It is one of the best water purification systems these days. It uses semi permeable membrane for filtering water. Also referred to as RO, it removes dissolved minerals and toxic in water, which are much smaller as compared to water molecules. Membranes working on the principle repel the impurities from the surface. The system for purifying water removes impurities such as microorganisms, other heavy organic matter, bacteria and turbid material. Its pores are of the size 0.005 microns - 0.0000002 inch.

The membranes are most commonly of the cellulosic category. Cellulose triacetate (CTA) and cellulose acetate (CA) fall under this category. The latest technology includes TFC or thin film composite type. To conduct reviews, we have to take a look at the pros and cons of CA and CTA system. One of the shortcomings of CA or CTA is that they are prone to gradual bacterial growth that takes place on the surface of the membrane, in case of usage in non chlorinated water supplies. For disinfected water supply, CTA membranes are more resistant to chemical and bacterial encounter. TFC systems are the best water filtration systems, and advantages of this system are, more immune to bacterial growth and increased resistance in case of adverse pH conditions.

5 Stage System

In 5 stage reverse osmosis system, water is filtered in 5 stages such as sediment pre filtering in stage one, activated carbon block filtration in stage two, filtration through the membrane in stage 3, carbon block post - filtration in stage 4 and UV sterilization in stage 5. The features of a 5 stage system include, economical maintenance cost, easy installation, versatility in design, 0.0005 micron filter, easy integration with water dispenser and carbon pre and post filtration utility. Whole house reverse osmosis water filtration systems, like Niagara uses fleck valve to trigger backwash of water to clean the filter bed. These systems work best in case of private water supply or municipal water supply.

Installation

Here is an overview for installing this system. Follow these steps when you are installing water filtration system.

Step 1: To ensure that there is no leakage in the system, tighten all the fittings, which will restrict the entry of contaminants into the system.

Step 2: Lodge water filtration system in an area where there is no freezing temperature surrounding the system. The best place to fit in the water purification system would be the basement, underneath sink or on counter tops. Avoid the system from getting exposed to direct sunlight. It is risky for the plastic material used in the system.

Step 3: If you are planning to disengage the line for portable water, make sure to get an approval from the local authorities, wherein you can get a licensed plumber to do the installation of the system.

Step 4: Link the drain line of the system with the waste pipe of the sink for draining impurities in the water.

Step 5: With the help of a saddle valve, connect cold water source with the inlet water pipe. Fix shut off valve for preventing water flow, in case storage container is fully filled with water.

Step 6: The last step is faucet installation, followed by refrigerator line installation.

This was all you need to know about the process of reverse osmosis, the water filter system, the mechanism it uses, and the installation. I hope you found the content on reverse osmosis useful.
