Seawater Desalination Plant with Dual-Inlet RO Membrane

I.Concept:

This system is designed to convert seawater into safe, potable drinking water using advanced reverse osmosis (RO) technology. The dual-inlet RO membrane ensures a longer purification flow path, enhancing filtration efficiency and speed while reducing fouling. It is ideal for industrial, municipal, or remote water supply applications.

II.Flowchart:

Seawater Intake →Pre-Filtration (Sand & Carbon Filter) →High-Pressure Pump →Dual-Inlet RO Membrane →Post-Treatment (UV / Mineralization, optional) →Clean Drinking Water Storage

III.Specification

IV.Application:

Coastal towns and islands

Remote or off-grid communities

Industrial plants requiring potable water

Marine vessels and offshore platforms

Emergency water supply projects

Identify needs

Clarify the following issues, and you can determine the right equipment for you.

Water quality problems

Example 1: sediment exceeds the standard/scale / turbid water / microbial exceeds the standard/ heavy metal exceeds the standard/money Yu exceeds the standard, etc.

Water standard

Example 1:Softened water/pure water/ultra-pure water/iron and manganese removal/sediment removal/sterilisation, etc.

Daily Water Consumption

Example 1:Whether there is a concentrated water consumption period/water consumption time/peak maximum water consumption/hourly average water consumption

Conclusion Example

5 tonnes per hour water softening equipment.

3 tonnes per hour reverse osmosis water purification equipment

If you can't answer the above questions clearly?

1. Daily Water Consumption: Just mail a bottle of water sample

2. Water Standard: Just tell me your industry.

3. Water Consumption: We can help you calculate the water consumption.
