Abtech Environmental Services offers various types of water treatment products which include softeners, deionisers and reverse osmosis systems. Softeners provided by Abtech Environmental Services are mainly used for the removal of water hardness. Certain salts contribute to water hardness like calcium, magnesium as well as iron. Softener provided by Abtech Environmental Services comprises of a tank that consists of softener resins. As the hard water enters this tank, it gets percolated through the resin bed causing all the hardness contributing salts to be exchanged with sodium salts. This results in removal of water hardness. Abtech Environmental Services provides twin tank softeners with flow rate of about 200 litres per minute.
Deionisers provided by Abtech Environmental Services function by removing salt contents from water. This is achieved basically by Ion Exchange method. These are fixed bed systems that contain ion exchange resins within pressure tanks. The water that has to be deionised has to be brought in contact with this resin. The anionic as well as cationic resins present in this deioniser have the ability to remove considerable amount of ionisable solids.
Reverse osmosis systems designed by Abtech Environmental Services can be used for salt removal from water. This is achieved by application of pressure to high concentration of the membrane. This membrane present in reverse osmosis system is a semi permeable one which enables the flow of liquid from a state of low concentration to high concentration.
