Remotox, a Calcium Polysulfide Solution for treatment of heavy metals in soil, groundwater and wastewater.

REMOTOX® removes chromates and dichromates without prior reduction of the chromium to its trivalent state. Electrolyse nickel and other metals in process wastewater are effectively treated. It breaks and precipitates chelated and/or complexed metals without pretreatment. REMOTOX can be adapted to enhance any existing treatment system.


REMOTOX® is considered to be an ideal reducing agent for soil and groundwater remediation, due to its effective ability to stabilize heavy metals and other pollutants. It precipitates highly soluble metals as less soluble, less toxic metal sulfides. Hexavalent chromium, Cr(VI), is reduced to trivalent levels, Cr(III), which then precipitates as a hydroxide.

REMOTOX® has proven to capture high levels of mercury in flue gas and scrubber solutions, preventing re-emissions. It has also proven effective in removing lead, copper, thallium, cadmium, nickel, zinc, iron, silver and other metals commonly found in power plant waste and scrubber wastewater.

This versatile multivalent ion sulfur chemistry has been well-studied and successfully applied in various industries over the past 40 years for the remediation of a wide range of heavy metals and other contaminants.
