There are treatment options to reduce total dissolved solids in water, such as reverse osmosis system, water filters, and softeners. Reverse osmosis is considered to be one of the best available solutions to reduce the water TDS level and to meet many treated water quality requirements. Electrodialysis consists of moving the salt water through electrically charged membranes that trap the salt ions dissolved in the water, allowing fresh water to be extracted. Desalination is the process of getting salt out of saltwater so that it's drinkable and usable on land. There are two main techniques: Boil the water, and then catch the steam, leaving behind the salt. Or blast the water through filters that catch the salt but let the liquid through. Therefore three methods/techniques used for TDS from water i.e., Ion exchange are used to reduce the total dissolved salts especially hardness causing ions like calcium and magnesium are replaced by the sodium ions. Clark’s method TDS of water can be removed by adding lime and soda ash. Lime and soda ash precipitates carbonates, bi-carbonates and sulphates of calcium and magnesium mainly responsible for the hardness of the water. Thus supernate water low TDS. Distillation this process involves boiling of water and then collection of the steam Thant condenses to form water of low TDS. Ion Electrosorption this technique, water is passed through charged carbon electrode that adsorbs the opposite charged ions.
