4T Solar RO Desalination Plant – OEM System For Seawater & Brackish Water Purification
I.Product Conception
The 4T Solar RO Desalination Plant is an advanced, energy-efficient water purification system designed to convert seawater and brackish water into clean, potable water. Powered by solar energy, this unit offers a sustainable solution for remote areas, islands, coastal communities, and off-grid applications where fresh water is scarce.
Engineered with a high-performance Reverse Osmosis (RO) process, the system effectively removes salt, minerals, and impurities, delivering reliable fresh water output of up to 4 tons per hour. The integrated solar power supply significantly reduces operational costs and environmental impact, ensuring continuous operation even in regions without stable electricity.
As an OEM customizable system, it can be tailored to meet specific water quality standards, local conditions, and capacity requirements. Compact, durable, and easy to install, the 4T Solar RO Desalination Plant combines modern technology with eco-friendly design — making it an ideal choice for industrial, municipal, and emergency water treatment applications.

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
