Product Description

Seawater Desalination Plant Factory RO Equipment Seawater/Water Treatment Unit

Seawater desalination process and parameters
①Seawater desalination process:
Raw water tank→bactericide→two-stage quartz sand filter→scale inhibitor/reductant→precision filter→high pressure pump→reverse osmosis membrane→product water sterilization→product water tank
②Production water quality:
Product water TDS＜500, turbidity＜0.1

Seawater Desalination Equipment Design Scope

①Sea water intake system
②Seawater desalination pretreatment system (self-cleaning + multi-media filter)
③Seawater desalination equipment, the water quality of the produced water can meet the water quality standard of the project. Seawater desalination equipment is in the form of containers, and its electrical, instrumentation and control systems are controlled by PLC, which greatly reduces the cost of on-site civil construction. The technological process is simple and smooth, automatic/manual operation can be realized, and the effluent water quality is reliable and stable.
