Desalination Plant

Desalination Plant

We offer Sea water desalination reverse osmosis plants for production of low TDS permeate from sea water. The sea water desalination units are constructed based on a process expertise and an on-field experience we own backed by leading membrane manufacturers like dow film tech Hydranautics and GE osmonics etc. The desalination units are custom-made in combination with a site specific pre-treatment and sea intake system. The pre-treatment section is designed based on the input sea water quality and ensures that the right quality of sea water is provided as feed to the RO at all times. Typical pre treatment system envisage Disinfection at intake point Coagulation settling Disinfection Filtration Optional Upgrade packages include Feed pump Pre-treatment filter Chemical dosing systems Auto flushing Micro PLC based controller CIP system with cartridge pre filter Process Description: Pretreatment : Before the RO process, seawater entering the desalination plant flows through screens that remove debris, then goes through a traditional treatment process called coagulation and flocculation. In this process, chemicals are added to the seawater to make algae, organic materials and particles clump together so they can be removed more easily in the sand filtration stage. After sand filtration, the salty water goes through diatomaceous earth filters to remove silt and fine particles. Cartridge filters just before the RO membranes serve as a backstop, removing any particles that may be remaining after the diatomaceous earth filters. Reverse Osmosis High pressure forces the pretreated water through semi-permeable membranes to separate the freshwater, leaving twice-as-salty seawater and other minerals behind.
