Video Description
This home membrane element features a high rejection rate, effectively removing heavy metals, bacteria, and other impurities from water to ensure safe daily drinking water
Membrane Protection and Pretreatment
Brackish groundwater treatment systems often require more careful pretreatment management compared with standard municipal water RO systems. Suspended solids, scaling minerals, hardness ions, and oxidizing agents may affect membrane performance during long-term operation.
Recommended pretreatment may include:
- Cartridge filtration
- Multimedia filtration
- Activated carbon filtration
- Water softening
- Dechlorination
- SDI reduction control
Proper pretreatment helps reduce membrane fouling, scaling, pressure increase, and salt rejection instability during operation.
Our Advantages
Our residential brackish water RO membrane products are manufactured in compliance with internationally recognized certification standards, including NSF, ISO, and CE requirements. These certifications reflect controlled production processes, material consistency, and quality management systems that support stable membrane performance in residential and brackish water reverse osmosis applications.
These certifications are widely accepted in OEM RO membrane manufacturing, bulk water treatment equipment procurement, and international distribution channels. For water treatment system manufacturers, distributors, and engineering contractors, certified RO membrane products can help simplify project approval procedures, reduce additional testing requirements, and support smoother integration into residential and commercial RO system supply chains across different markets.
FAQ
1.Can chlorine damage the membrane?
Yes. Free chlorine concentration should remain below 0.1 ppm because oxidizing agents may damage the membrane surface and reduce rejection performance.
2.What contaminants in well water can affect RO membrane performance?
Common contaminants include suspended solids, hardness minerals, silica, iron, manganese, organic matter, colloids, and biological contaminants. These substances may increase fouling and scaling risk if pretreatment is not properly controlled.
3. How often should the membrane be cleaned?
Cleaning frequency depends on feed water quality, pretreatment condition, operating pressure, recovery rate, and system operation. Systems operating with insufficient pretreatment or unstable groundwater quality may require more frequent cleaning.
