XtremeUF ceramic ultrafiltration removes oils, grease, precipitated by-products, particulate, microbes, and suspended solids.
High recovery treatment solutions
When freshwater is scarce or costly, treating and re-using wastewater can represent a cost-effective and sustainable water supply. Saltworks provides optimized wastewater reuse solutions that maximize and cost-optimize treated water recovery.
Wastewater Reuse Solutions
Applying targeted treatment to enable wastewater reuse can substantially lower freshwater procurement costs, while improving sustainability of operations. Harvesting valuable reagents, metals, nutrients, and more from spent wastewater can also add a lot of value for some industries.
Wastewater reuse considerations start with chemistry, permits, and an applicable technology review. It may be that only one or two constituents-of-concern prevent re-use, and that by targeting their removal, massive volumes of water can be recycled. In other cases, you may require extremely clean freshwater with minimized brine residual by-products.
Wastewater treatment solutions for re-use may involve some of the following options:
- Target contaminants of concern with our IonSelect solutions: remove specific ions, metals and others for optimal water reuse. Keep costs low by not treating the entire flow.
- Remove scaling ions with BrineRefine: our automated chemical softening system can selectively remove scaling species such as calcium, sulfate and silica. For example, it can enable greater recycling in cooling towers, limiting freshwater consumption and blowdown volumes generated.
- Concentrate and make freshwater with XtremeRO: our next generation reverse osmosis systems can produce freshwater, and a low volume brine.
- Selectively remove chlorides with FlexEDR: our monovalent ion extraction system, which can function as a “chloride kidney” removing chlorides from your wastewater.
- Achieve MLD/ZLD with SaltMaker: our advanced evaporator crystallizers reach maximum water recovery with minimum brine or solid waste.

XtremeRO maximizes recovery & minimizes brine for tough industrial wastewaters. Our UHP RO delivers the highest recovery in the industry.
FlexEDR is a next-gen electrodialysis reversal (EDR) system for industrial wastewater desalination, solving scaling issues & boosting recovery.
Treating RO brine should be approached from two directions. First, maximize the recovery of lower cost membrane systems to minimize the volume for later steps. Second, weigh brine disposal options against thermal treatment technology to determine whether you need to concentrate your brine or treat it down to solids.
Cooling towers are used by industrial plants to reject waste heat to atmosphere. A portion of the cooling water is blown down after a number of cycles of concentration, before the ions and metals reach their scaling limits. This blowdown requires management.
New modular, intelligent, and automated chemical precipitation with a ceramic membrane filtration system eliminates the challenges of chemical overdosing and large footprint requirements.
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).
