Description : | CSMCRI, Bhavnagar has developed a unique water desalination system, which uses animal energy to energize the high-pressure pump to effect brackish water desalting by RO process. Water desalination system having animal power as prime mover consists of speed increaser, high-pressure pump and membrane modules. The above system can produce 300-500 LPH product water for feed water TDS (total dissolved solids) in the range 3000-5000 ppm. A pair of bulls is connected to one side of a mechanical link (as shown in photograph) while the other side of the link is coupled to the input shaft of a gearbox, comprising various sets of gears. The gearbox is designed to convert bullock power in the form of low rpm and high torque at the inlet shaft into mechanical power of high rpm and low torque at the output shaft. The output shaft is coupled to the crankshaft of the reciprocating high-pressure pump, which discharges 1200 LPH feed water. Harmful elements such as fluoride, arsenic, nitrate and heavy metals are simultaneously removed along with other salts during the desalination process and the permeate water is also free from bacteria. |
