Heavy Metal Removal from Wastewater

Chokhavatia Associates understand just how critically important the reduction in the concentration of heavy metals removal is in waste wastewater, both in regard to the environmental impact, and to the impact it may have on industrial processes. Many countries and municipalities place stringent limits on the concentration of various metals that may be discharged either directly to the environment or to a treatment plant.

Heavy metals are a major concern because of their toxicity and other detrimental effects they may present. In general, heavy metals are considered to be the following: Copper, Silver, Zinc, Cadmium, Gold, Mercury, Lead, Chromium, Iron, Nickel, Tin, Arsenic, Selenium, Molybdenum, Cobalt, Manganese, and Aluminium.

Typically, metals can find their way into the wastewater system as a result of industrial processes including the following:

  • Metal mining and smelting operations.
  • Foundries.
  • Metal plating and finishing.
  • Metal fabricating plants such as automotive manufacturing, etc.

When heavy metals are present in a waste stream they can interfere with, and even destroy, the effectiveness or operation of normal waste treatment. Heavy metals in water can make it unsuitable for drinking, boiler feed, or processes that rely on high levels of purity.

Chokhavatia Associates offer a comprehensive range of technologies and solutions for the removal of heavy metals. We design and implement solutions that are designed to improve environmental conformity, conserve valuable resources and control the cost of operation.
