What does Graus Chemicals specialize in?
Graus Chemicals specializes in supplying REMOTOX®, a calcium polysulfide solution used primarily in environmental remediation. The company serves industrial, municipal, and mining customers across North America with applications in soil, groundwater, wastewater, and air pollution control.
What is REMOTOX®?
REMOTOX® is an aqueous calcium polysulfide solution designed for the cost-effective remediation of heavy metals, chlorinated solvents, and other contaminants. It is a water-soluble reagent that oxidizes under aerobic conditions to form calcium, sulfate, and elemental sulfur.
What industries or applications is REMOTOX® used for?
REMOTOX® is used in several key application areas, including:
Soil and groundwater remediation
Industrial and municipal wastewater treatment
Air pollution control and flue gas treatment
Mining and environmental cleanup projects
It is specifically used to help capture, reduce, or precipitate heavy metals and other contaminants.
What contaminants can REMOTOX® help treat?
REMOTOX® is commonly used to address contaminants such as:
Hexavalent chromium (Cr VI)
Lead
Copper
Nickel
Zinc
Cadmium
Mercury
Silver
It can also be used to treat other dissolved or suspended heavy metals in soils, groundwater, wastewater, and combustion-related waste streams.
Why choose REMOTOX® over other treatment reagents?
REMOTOX® offers several advantages, including:
High reactivity with heavy metals
Ability to form less soluble metal sulfides over a wide pH range
Effective treatment of some chelated or complexed metals
No need to dissolve prior to use
Low crystallization temperature
Stability in storage and transport
Potentially lower overall treatment cost compared to some alternatives
These benefits can make it a practical option for many remediation and wastewater treatment systems.
Is REMOTOX® available in different packaging and shipment options?
Yes. REMOTOX® is available in:
Pails
Drums
IBC totes
Bulk tank truckload quantities
This flexibility allows the product to support both small-scale and large-scale remediation or treatment projects.
How should REMOTOX® be stored and handled?
REMOTOX® should be stored in compatible materials such as stainless steel, fiberglass, HDPE, polypropylene, ABS, PVC, and Teflon. Because the product is corrosive due to its caustic nature, users should wear appropriate PPE, avoid skin and eye exposure, use it outdoors or in well-ventilated areas, and avoid mixing it with acids, combustibles, or oxidizers.
How long does REMOTOX® remain effective in storage?
When tightly sealed and stored at a moderate temperature, REMOTOX® has been tested to maintain effectiveness for a minimum of one year.
Is REMOTOX® approved or suitable for potable aquifer or drinking water-related applications?
REMOTOX® is suitable for certain potable aquifer and drinking water-related applications, depending on project requirements and applicable regulations. Because approvals and use conditions can vary, customers should confirm current certifications and site-specific compliance requirements before use.
