Saltworks is pleased to release a new technology map for achieving complete system ZLD and LCE production. Saltworks’ CEO, Ben Sparrow, also covered the same topic on the “(Don’t) Waste Water” podcast, hosted by Antoine Walter.
Saltworks has delivered a complete zero liquid discharge (ZLD) industrial desalination solution to a mining site in the US. The uniquely modular and digitized plant enabled the client to rapidly install and implement the intelligently automated ZLD system with reduced inputs.
For cost-optimized ZLD, most projects need an ideal blend of membrane, chemical, and thermal stages to minimize costs, maximize freshwater recovery, and reduce waste products. Saltworks’ innovative, modular, and digitized products operate as standalone units or can be packaged together into a complete system.
The delivered plant integrates BrineRefine, XtremeUF, XtremeRO, and SaltMaker MVR for optimized performance and costs. In Saltworks’ ZLD solutions, each technology is delivered on a compact skid, fully equipped with controls and support systems for quick deployment and easy installation at the client’s site. All interconnections and digital controls are provided, further accelerating installation, start-up and lowering integration costs.
To optimize cost and energy use, maximizing reverse osmosis (RO) system recovery is key. This requires protecting RO units from scaling and fouling as higher concentrations are reached. Because the initial wastewater feed is saturated in scaling ions, Saltworks’ BrineRefine continuous stirred tank reactor (CSTR) first precipitates out solids, then allowing our XtremeUF ceramic ultrafiltration unit to reject the resulting sub-micron precipitants.
Saltworks’ standardized, repeatable, and digitized modular plants are available to serve your industrial desalination or lithium refining projects.
Saltworks Technologies is a leader in the development and delivery of solutions for industrial wastewater treatment and lithium refining. By working with customers to understand their unique challenges and focusing on continuous innovation, Saltworks’ solutions provide best-in-class performance and reliability. From its headquarters in Richmond, BC, Canada, Saltworks’ team designs, builds, and operates full-scale plants, and offers comprehensive onsite and offsite testing services with its fleet of mobile pilots.
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.
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.
Zero liquid discharge (ZLD) is an engineering approach to water treatment where all water is recovered and contaminants are reduced to solid waste.
