A leading iron and steel group in Sichuan integrated Hedelong’s FRP membrane housings into its industrial wastewater treatment system, targeting efficient purification of high-salinity, corrosive wastewater generated during steelmaking processes.
Hedelong’s membrane housings, crafted from high-quality fiberglass and epoxy resin via CNC-controlled automatic pouring, deliver exceptional corrosion resistance and high mechanical strength—effectively withstanding harsh conditions like high pressure and chemical-rich wastewater in steel production. Validated by rigorous pressure tests (1.5 times the standard pressure) and operating stably within -7°C~49°C, they adapt perfectly to the group’s continuous industrial operation demands.
With customizable pressure ratings (150-1000 PSI) and connection types tailored to the plant’s existing treatment system, coupled with Hedelong’s professional after-sales support, the housings have significantly improved the stability of the reverse osmosis system, reduced equipment maintenance downtime, and ensured compliance with strict industrial discharge standards—winning full recognition from the group’s engineering and operation teams.
