Hearing the name reverse osmosis may seem like a very complex filtration process for the neutrals. But in reality, this filtration process is quite simple and straightforward. It has been used for several years to purify water and make it clean for drinking. Having a better knowledge of the main functions of a reverse osmosis system will remove any confusion and misery surrounding the system. Continue reading to find out the features of a best reverse osmosis system and what they can do for you. But before we go on, it will not be a bad idea to understand how the whole system really works.
How Does a Reverse Osmosis System Really Work?
RO is used to remove dissolved organic solids from a solution (mostly water). This process is achieved as water is pressure-pushed from external water supply through a semi permeable membrane. The membrane does not give space for any other substance apart from water. The dirt and debris are trapped inside the membrane as clean and pure water comes out from the membrane. These contaminants and impurities are then flushed down the drain. This is the basic idea behind the functionalities of a reverse osmosis system.

Some Features of a Reverse Osmosis System
-
Cold water valve:
This is a valve that takes in the cold water supplied from outside sources. The valve has a tube-like substance attached to the inner side of the filter. It draws and supplies water for the reverse osmosis system.
-
Pre-Filters:
This is where water from the cold water valve passes through. Some RO systems have more than a single filter. The filter plays a major role in any RO system because it is used in removing sediment, dirt and sand silt. In addition, there are some RO systems with carbon filters which are used in removing chlorine.
-
RO membrane:
Reverse osmosis membrane is the major part of the entire system. There are different types of RO membranes but the most common is the spiral wound which can be grouped into the TFC/TFM composite material and the CTA (cellulose tri-acetate).
-
Post filter:
The post filter is the destination of the filtered water after it leaves the storage tank. The water will need to pass through the post filter before finally going into the faucet. This filter is usually carbon, either in block or in granular form. It is here any remaining odor or taste is removed from the water before it goes into the faucet.
-
Shut-off valve:
This is a water conservation feature found in most newly designed RO systems. It is intended to prevent the waste of water when storage tank is full. When this tank gets full, the valve automatically stops the passage of water into the tank to prevent water from going through the membrane. As water is stopped, it also prevents it from passing to the drain, thereby helping to preserve water. But once the pressure in the water tank is reduced and water comes out from the faucet, the valve opens up again and allows water to pass through.
-
Storage tank:
Without the storage tank, the RO system will not see enough water to filter and send to the faucet. It can hold about 3 gallons of water at a time. There is a bladder in the storage tank that usually keeps the water pressurized when the tank is full.
-
The Faucet:
This is where the water comes out after going through the filtration process by the RO system. It is generally installed separately on the kitchen sink for ease of access and efficiency. There are different types of faucets in an RO system but the most basic thing about a faucet is to be able to release enough water from the tank for consumption.

HI, We have an issue with the DOT compromising our well with their road salt. Their salt bin is 100 feet from our well and it is eating up everything in our home including the stainless steel sinks.
Ate up 1 dish washer and eating our clothes washer. Need to see if installing an RO system for the dishwasher and laundry washer (front loader) and dish washer. 2 Separate systems. 1 for DW, 1 for LW.
Is this viable? Also looking at collecting rain water for both. But too many other projects in the way first.
I do have a GE whole house system carbon filter on the main, but not enough.
Do you think an Ro will help?
I really don’t know where to go from here, other than to the Town and scream for a solution, i have way too many other things to deal with than that. We have a company we need to get moving. I don;t have the tine to fight with the town. My company has bee making electric boats since 1893, this is what I do. Don’t have time to deal with home stuff. Till way after hours.
Thanks
Jim
