Calcium Polysulfide has been in use for more than a century, but primarily for agricultural applications. Today, it is routinely used for effective treatment of heavy metals and other contaminants found in soil, groundwater and wastewater.

Remotox® is a calcium polysulfide based solution that consists of multiple sulfur compounds which strongly bond to heavy metals in water. The metal sulfides formed have a very low solubility and persist as stable solids, which allows for a more economically feasible and environmentally sound disposal.  

Chromium, zinc, copper, lead, cadmium and mercury are among the most common metal contaminants found on clean-up sites. Remotox® precipitates these highly soluble metals as less soluble, less toxic metal sulfides. Hexavalent chromium is reduced to trivalent state which then precipitates as chromium hydroxide in a one-step process.

Remotox® for the removal of a wide range of heavy metals and other potentially harmful compounds commonly found in laboratory waste streams. Reducing hazardous waste on site to the minimum quantity can save transportation and disposal cost.

Remotox® for capturing heavy metals from flue gas and scrubber wastewater. REMOTOX has proven to remove high levels of mercury from scrubber solutions, preventing re-emissions. It can also remove and stabilize lead, copper, thallium, nickel, zinc, iron, silver and other metals commonly found in power plant waste streams.
