Application Scenarios
- High-salinity wastewater concentration: Reduce the volume of concentrated brine from chemical and manufacturing lines to lower downstream treatment load.
- Landfill leachate treatment: Apply high-pressure RO to leachate streams for deep purification and concentrate reduction.
- Industrial water reuse: Recover clean process water from industrial effluent to ease fresh water demand.
- Zero liquid discharge support: Raise water recovery on high-TDS feeds to move closer to ZLD targets.

Operating Precautions for Membrane Modules
During startup, shutdown, cleaning and other operations, sudden changes in pressure or crossflow velocity to spiral wound elements shall be avoided to prevent potential membrane damage. For startup, we recommend the following procedure to bring the system gradually from standstill into operation:
- The feed water pressure shall be increased gradually within 30~60 seconds;
- The designed crossflow velocity shall be reached gradually within 15~20 seconds;
- Permeate produced in the first hour shall be discarded;
- Once the membrane element is wetted, it shall be kept wet at all times;
- The user shall be liable for damage to elements caused by incompatible chemicals and lubricants;
- The maximum allowable pressure drop for a single pressure vessel is 50 psi (3.4 bar);
- Backpressure on the permeate side must be avoided at all times.
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.
