Seawater Desalination System

This desalination system supports customization from 30T/Day to 1000T/Day. If your water production is small, please refer to the Small Desalination System.
If you need a containerized desalination plant, please check out our Containerized Desalination Systems.
Product Overview
Reverse Osmosis (RO) seawater desalination systems are advanced solutions designed to convert seawater into clean, potable water by leveraging semipermeable membranes and high-pressure technology. MINGMO’s desalination equipment uses high-end RO technology, with a desalination rate of up to 98.5%, while greatly reducing energy consumption.

Main Components of Seawater Desalination Equipment
- Source water tank: ensure the water supply to the downstream
- Source water pump: increase water pressure to downstream equipment
- Multi-media filter: pretreatment, interception of large suspended particles
- Precision filter: filter suspended matter ≥1um in water to avoid membrane scratches
- Desalination unit: used to remove salt, suspended particles, colloids, microorganisms, etc. in water
- Pure water storage tank: store purified water
