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.

MONITORING
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:

BrineRefine Chemical Softening System
Smart, compact, modular chemical softening system that reduces costs with precision dosing and built-in solids management. Improves recovery and minimizes fouling risk with intelligent controls that communicate with downstream assets, like RO or evaporators.
Flex EDR
Flex EDR is an advanced electrodialysis reversal (EDR) system, leveraging our next generation ion exchange membranes. It requires less pre-treatment, tolerates oils and organics, selectively removes ions and uses fewer chemicals.
SaltMaker
MultiEffect
Modern, modular, and intelligently automated evaporator-crystallizer that concentrates brine or produces low volume solids for zero liquid discharge.
XtremeRO/NF Brine
Concentrator
Next-generation water-maker and brine-concentrator based on reverse osmosis that achieves extreme freshwater recoveries, enabling cost-effective brine management and treatment of challenging organic-laden waters including oil & gas produced waters.
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.
RO recovery and RO brine concentration is limited by osmotic pressures or membrane scaling; both limits have been increased by new technology. A series of techniques described in this document can be used to delay or mitigate scale, but in many cases only chemical softening truly removes the risk.
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.
