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.

Frequently Asked Questions
Common questions about RO membrane housing selection, installation, and maintenance
Material selection depends on your water chemistry and operating conditions. Stainless steel 316 is recommended for high chloride environments, while 304 works well for most municipal water applications. FRP housings are cost-effective for low-pressure applications.
Choose a pressure rating at least 1.5 times your operating pressure. For typical RO systems operating at 200-250 PSI, a 300-400 PSI rated housing provides adequate safety margin. High-pressure systems may require 600 PSI rated housings.
Inspect O-rings and seals every 6 months or during membrane replacement. Replace O-rings annually or if signs of wear are visible. Clean housing interior during each membrane change to prevent biofilm buildup.
Yes, most standard housings are compatible with various membrane brands. Ensure the housing length matches your membrane requirements and that pressure ratings are adequate for your system operating conditions.
Ensure proper support for housing weight when loaded with membranes. Allow adequate clearance for membrane removal. Install pressure gauges at inlet and outlet for monitoring. Use proper torque specifications for end caps to prevent leaks.
