Membrane Pilot Achieves 98% Water Recovery in Southeast Asia

Complex Manufacturing Wastewater Treated by Ultra-High Pressure Reverse Osmosis

July 6th 2021

Saltworks’ Advanced Membrane Plant Goes Intercontinental

Our ultra-high recovery membrane pilot plant has successfully completed another tour of duty. After arriving in Southeast Asia earlier this year, the plant operated continuously around-the-clock for 90 days, achieving 98% water recovery from a complex, mixed industrial wastewater with high organics and variable water chemistry.


The advanced pilot plant crossed the Pacific Ocean with a quick turnaround after its cooling tower blowdown trial at an agri-chem facility—for which Saltworks is now designing and building a full-scale, permanent installation.

Ultra-High Recovery Expertise and Technologies, On-Site for Saltworks’ Clients 

Our expert pilot team operated the plant both on-site and remotely despite the ongoing international challenges of the COVID-19 pandemic. High performance Nitto HYDRANAUTICSTM PRO-XP1 membranes were once again employed to great effect, as well as Saltworks’ advanced process technologies that enabled the membranes to perform: BrineRefineXtremeUFScaleSense, and XtremeRO.


The system treated variable water quality originating from multiple streams, consistently achieving 98% recovery and concentrating a sodium sulfate-rich brine to over 200,000 mg/L total dissolved solids (TDS). The 2% brine volume is small enough such that direct solidification becomes viable, avoiding the need for an energy intensive evaporator-crystallizer.


As the need for ultra-high recovery industrial water recycling grows, our production facility is bustling with full-scale build-outs of XtremeUF, XtremeRO, FlexEDR, and SaltMaker plants. End user industries include range from microelectronics to brackish water desalination, lithium refining, and oil and gas processing.
