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.

Coal Ash Pond Water Treatment: Technology Options

Coal ash pond water may require treatment because leached pollutants from ash pond water pose human health and ecological risks. Consider membrane concentrators, minimal liquid discharge (MLD), and zero liquid discharge (ZLD) technologies to reduce brine volumes from treating leachable pollutants.
