APPLICATION
Small Commercial RO System
For systems operating at 300 PSI, this ro membrane filter housing is suitable for small-scale water treatment setups or specific industrial applications where lower pressure requirements are sufficient. At this pressure level, the membrane housing operates stably, ensuring smooth water filtration while maintaining system safety and reliability. For example, in household or small commercial reverse osmosis systems, a working pressure of 300 PSI is adequate to meet daily water purification needs, providing clean drinking water or fulfilling certain industrial process water requirements.
Industrial RO System
As the operating pressure increases, reaching up to 600 PSI, the 2.5-inch end-cap series of RO fiberglass membrane housings performs excellently in medium-scale industrial water treatment. This pressure level is suitable for applications that require higher water quality and larger treatment capacity. The high-strength fiberglass material of the housing can withstand elevated pressures, ensuring no deformation or damage occurs during long-term operation. At the same time, the reasonable design and manufacturing process allow the housing to maintain good sealing performance under high pressure, preventing water leakage and the intrusion of external contaminants.
Seawater desalination, chemical industry
When the operating pressure reaches 1200 PSI, this series of products demonstrates outstanding performance and reliability. Such high pressure is typically suitable for large-scale industrial water treatment projects or specialized applications, such as seawater desalination, the chemical industry, and other demanding water treatment fields. Under such high pressure, the housings, thanks to their high-quality materials and exquisite manufacturing process, can operate stably, providing users with efficient and reliable water treatment solutions.
