RO Membrane Housing Overview
Discover the essential components that ensure optimal performance and longevity of your reverse osmosis water filtration system
Purpose & Importance
RO membrane housings serve as the protective shell for reverse osmosis membranes, creating a sealed environment where water filtration occurs under pressure. These critical components ensure that contaminated water is properly channeled through the membrane while maintaining system integrity.
In reverse osmosis systems, the housing acts as the pressure vessel that contains and supports the semi-permeable membrane, directing water flow and maintaining the necessary pressure differential for effective contaminant removal. Without proper housing, even the highest quality membranes cannot perform optimally.

Drinking Water Purification
Essential for removing contaminants, chlorine, and dissolved solids from tap water. Residential systems typically use 4-6 inch housings, while municipal facilities require large-diameter industrial housings for high-flow applications.
- Home under-sink and whole-house systems
- Community water treatment plants
- Bottled water production facilities

Industrial Process Water
Critical for manufacturing processes requiring consistent water quality. Industrial-grade stainless steel housings handle high pressures and corrosive environments while maintaining operational efficiency.
- Chemical processing and refineries
- Textile and paper manufacturing
- Metal finishing and plating operations

Brackish Water Desalination
Converts brackish groundwater into potable water for communities with limited freshwater resources. Operates at moderate pressures with specialized membrane configurations for optimal salt rejection.
- Rural and remote community water supply
- Agricultural irrigation systems
- Golf course and landscape irrigation

Seawater Desalination
Requires high-pressure stainless steel or specialized FRP housings to withstand extreme operating conditions. Essential for coastal regions and islands with limited freshwater access.
- Large-scale municipal desalination plants
