Application Scenarios
- Coastal industrial water supply: Treat seawater and brackish water for various coastal factories to produce standard boiler water and process pure water, reducing enterprise water costs.
- Power plant pure water preparation: Suitable for coastal thermal power, hydropower and nuclear power projects. It deeply treats raw water to produce boiler make-up water and unit process pure water for stable plant operation.
- Coastal municipal water supply: Realize seawater resource utilization in coastal cities to expand municipal drinking water sources and ease freshwater shortage.
- Island seawater desalination: Provide seawater desalination for islands and offshore platforms to stably supply domestic and production water.
- Marine vessel water supply: Seawater desalination for ocean-going vessels to supply domestic fresh water on board.
- Coastal resorts and scenic areas: Seawater purification for coastal resorts and scenic parks to meet daily water demand.

Judgment of Membrane Fouling
How to identify membrane fouling. Key parameters are listed below:
(1) The most critical indicator is the difference in membrane flux (units such as LMH or LPM) under identical operating conditions (same pressure, temperature and recirculation flow rate). Generally, membrane fouling is confirmed when the flux of used membranes drops below 85% of that of new membranes.
(2) Membrane fouling usually leads to changes in membrane rejection performance, which may either increase or decrease.
(3) Under identical operating conditions, the pressure difference across the membrane module rises after fouling, which means the transmembrane resistance increases.
Warranty Period
The company warrants the performance of membrane elements for three 3 years. The three-year warranty period shall commence on the earliest of the following dates:
- The date when the reverse osmosis system is put into operation;
- Six 6 months from the date the membrane elements are shipped from the manufacturing site;
- Three 3 months after the membrane elements are shipped from Guangzhou / Shanghai, China to Taiwan of China, Japan, South Korea, Thailand, India, Malaysia, the United States and other designated locations in China.
