Reverse Osmosis is a very popular and effective way to purify water. Reverse osmosis is easy to install, easy to use, and removes a vast assortment of water contaminants. Reverse osmosis is used for many applications including home drinking water and in many industrial and commercial processes. Reverse osmosis is a process where water is forced through a membrane with microscopic pores. Only pure water can pass through the pores in the reverse osmosis membrane. All other pollutants are flushed to the drain. Reverse osmosis systems differ in the number of stages (3, 4, or 5 stage) but all will produce high quality water. All reverse osmosis systems require regular pre-filter and membrane replacement in order to ensure a high quality and quantity of water production. aQuatell offers a full selection of reverse osmosis systems as well as a great selection of reverse osmosis replacement parts and accessories for home and industrial reverse osmosis systems.
