摘要：The a.m of this pa.er is to design a.wa.er desa.ina.ion pla.t using Reverse Osmosis membra.e to trea. sa.t wa.er to be usa.le for drinka.le, domestic, industria. or a.ricultura. uses. RO unit is designed to conserva.ive sta.da.ds for versa.ility in the event of feed wa.er qua.ity va.ia.ions. The design includes a.feed wa.er flush cycle to minimize membra.e fouling a.d piping corrosion during shutdown. The system will be a.l a.propria.e controls a.d instrumenta.ion for a.toma.ic opera.ion. a.l system components a.e a.a.la.le a.d of hea.y duty industria. design a.d fa.rica.ed with the highest qua.ity workma.ship. Qua.ity control will be ma.nta.ned throughout a.l ma.ufa.turing processes. The system will produce permea.e wa.er minimum of 3600 m3/da. with a.qua.ity of a.proxima.ely 100 ppm tota. dissolved solids (TDS) when opera.ing on well feed wa.er with a.10,000 ppm TDS a.d a.tempera.ure of 25 - 30 degrees C. The design permea.e recovery is 50%;a.d energy recovery device which sa.es $30,556.28/yea..
