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.
UHP RO Commercialised
Saltworks is thrilled to announce the first full-scale order for an industrial Ultra High-Pressure Reverse Osmosis (UHP RO) system with Nitto high performing HYDRANAUTICSTM PRO-XP1 spiral wound membranes rated to 1,800 psi (124 bar).
Ultra high-pressure RO builds on the pedigree of seawater reverse osmosis systems, but operates at a 50% higher pressure—beneficially halving the volume of brine generated. This means less waste and more clean water. Saltworks started working on UHP RO two years ago, quickly finding that HYDRANAUTICSTM membranes offered best-in-class performance. The company has since been pilot testing UHP RO on various customer applications including mining waters, factory wastewater, ion exchange regeneration waste, and cooling tower blowdown.
The first full-scale industrial client, a US manufacturer of advanced materials, will use the system for a win-win scenario: achieving a 10× reduction in disposal volume, while recovering clean water for re-use.
Saltworks’ CEO, Ben Sparrow, commented “We see wide applications for UHP RO to help clients save money, save water, and reduce waste. As PFAS becomes more important in North America, UHP RO is set to play a significant part of in solutions, driving down waste volumes sent to disposal wells or to destruction. In our testing, HYDRANAUTICSTM membranes have out-performed expectations and enable the next generation of reverse osmosis and brine recovery.”
Regarding this new membrane product, Hydranautics’ VP of Technology, Dr. Craig Bartels, added “As a technological leader in the industry, Nitto has a long line of industry ‘firsts’ as well as having advanced manufacturing facilities with the latest in automation technology. The PRO-XP1 is a new ultra high-pressure product in the PRO series line, which offers novel NF and RO products for treatment of the most difficult industrial wastewater applications.”

Reverse osmosis-based brine concentrators are reaching new performance levels not seen before. Saltworks is pleased to report that a substantial pilot plant is currently demonstrating 99% freshwater recovery on cooling tower blowdown (CTB).
Convention teaches that ZLD requires energy-intensive boiling to produce solids. Our engineers recently broke that convention and helped a mining client achieve solid salt production in a novel membrane-chiller hybrid plant using UHP-RO.
Our UHP RO minimizes brine from tough industrial wastewaters and delivers the highest freshwater recovery in the industry.
