Heavy Metals

Targeted water solutions

Heavy metals such as arsenic, cadmium, copper, lead, mercury, etc. can be critical components of many wastewaters and often require treatment. Conventional precipitation & coagulation (P&C) processes are well-practiced to treat heavy metals. Saltworks has modernized these processes to reduce footprint, maintenance, and operating costs.

Precipitation & Coagulation

In wastewaters burdened with heavy metals, physical-chemical precipitation converts soluble heavy metals to insoluble salts. The resulting precipitate must be removed by some combination of physical steps such as coagulation, clarification, and/or filtration. There are considerable opportunities in optimizing conventional precipitation & coagulation (P&C) processes.

Meet Treatment Goals

At times, only precipitation & coagulation (P&C) is required to meet a treatment goal, avoiding the need for more expensive desalination technology and/or a brine to manage. Beneficially, a P&C process produces only two outputs: treated water with metals removed, and a solid filter cake containing the removed metals. There are considerable opportunities in optimizing conventional precipitation & coagulation (P&C) processes to:
  • lower installed costs
  • save chemicals
  • save space
  • reduce wastes generated
  • ensure compliance, and
  • reduce operator burden.

Meet BrineRefine

Our BrineRefine system performs chemical treatment in a compact, pre-packaged, and intelligently automated manner. BrineRefine is

  • Designed for modularity in factory-built in ISO container skids, with built-in redundancy and expansion capability. This lowers installation costs.
  • Automated with precision dosing to ensure chemicals are not wasted and excess sludge is not generated. 
  • A smart solids management system, borrowed from our leading crystallizer solutions, reduces operator burden.
  • Compact: BrineRefine eliminates the need for large reaction vessels and clarifiers.
