Product Applications


Calcium Polysulfide has been in use for more than a century, but mainly for agricultural applications. Today, it is routinely used for the remediation of heavy metals.

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

Calcium Polysulfide removes chromates and dichromates, elctrolyse nickel, zinc and other metals in process wastewater.

REMOTOX®, a 29% Calcium Polysulfide Solution, is a non-toxic reagent that oxidizes under aerobic conditions to form calcium, sulfate and elemental sulfur. 

Soil and Groundwater


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 compounds. It precipitates highly soluble metals as less soluble, less toxic metal sulfides. Hexavalent Chromium is reduced to Trivalent levels, which then precipitates as hydroxide. 

Wastewater


REMOTOX® removes chromates and dichromates without prior reduction of the chromium to its trivalent state. Electrolyse nickel and other metals in process wastewater can be effectively treated. It can break and precipitate chelated and/or complexed metals, typically without pretreatment. 

Air Pollution


REMOTOX® has proven effective in removing lead, copper, thallium, cadmium, nickel, zinc, iron, silver and other metals commonly found in power plant waste and scrubber wastewater. It has additional proven to capture  heavy metals emitted by gases from various ignition processes.
