what we do

Water Treatment Plant

Our products include reverse osmosis machine, ultrafiltration equipment, seawater desalination system, electrodeionization unit etc. The water treatment plant have passed ISO,CE and other certifications, and so far have owned 2 trademarks, 3 software works, and more than 20 patents.

Reverse Osmosis Systems

Reverse osmosis system is a high-efficiency water purification device based on membrane separation technology. It uses high pressure to drive water molecules through a reverse osmosis membrane with a pore size of only 0.0001 microns, effectively removing pollutants such as dissolved salts, colloids, organic matter, and microorganisms from the water, thus achieving deep purification and reuse of raw water.

Seawater Reverse Osmosis Systems

It uses a semipermeable membrane to separate salts and impurities from seawater under pressure, achieving seawater desalination to obtain fresh water or water that meets standards.

Ultrafiltration UF Systems

It uses ultrafiltration membranes to retain colloids, macromolecular substances, and particulate impurities in water, thereby achieving water purification or pretreatment.

Brackish Water Desalination Plant

It uses a semipermeable membrane to separate salts and impurities from brackish water under pressure, achieving brackish water desalination to obtain fresh water.

Containerized Water Treatment Plant

Containerized water treatment plant is a highly efficient and environmentally friendly equipment that integrates advanced water purification technology with standardized container integrated design. It highly integrates the pretreatment system, main unit, intelligent control, cleaning and maintenance and water storage unit in a 20-foot or 40-foot standard container, realizing a closed-loop process from raw water purification to standard produced water.

Water Filling Machine

It is an automated or semi-automated production line that performs a series of operations such as filling, sealing, labeling and packaging on treated water.

How to desalinate water?

Seawater desalination technology uses physical, chemical, or biological methods to remove salt and various impurities from seawater, converting saltwater into fresh water suitable for drinking, agricultural irrigation, and industrial use. Current mainstream desalination processes each have their own advantages and disadvantages, and suit different application scenarios. How to desalinate water? The following text will provide a detailed breakdown of several core technological approaches.

What is the desalination machine?

97.5% of the Earth's water resources consist of highly saline seawater, with only 2.5% being freshwater resources, most of which are locked up in glaciers. Seawater desalination has become a core solution for water-scarce countries worldwide to overcome resource constraints, and in many coastal regions, it has upgraded from a supplementary measure to a strategic pillar.
