How Our Chemistry Works at Each Treatment Stage

Cationic coagulants handle primary coagulation and solids removal, and anionic and cationic polymer flocculants carry out secondary flocculation for clearer water. pH adjustment acid and base keep coagulation and flocculation in their ideal range, defoamers control foam in treatment tanks and clarifiers, bentonite builds floc mass and conditions sludge for dewatering, and metal scavengers remove heavy metals found in industrial waste streams. Custom-tailored, proprietary products engineered for use in commercial laundry applications.

Engineered chemistry for every stage of wastewater treatment and water recovery

Primary Treatment

Cationic Coagulants - Organic, Inorganic, Blends

Primary coagulation and solids removal for high-turbidity wastewater. Rapid floc formation, excellent settling characteristics. Custom-tailored, proprietary products engineered for use in commercial laundry applications.

Secondary Treatment

Polymer Flocculant - Anionic, Cationic

Secondary flocculation for enhanced water clarity and suspended solids removal. Optimized for post-coagulation treatment. Offerings in both powder and liquid emulsion.

pH Control

pH Adjustment Acid

Liquid acid for pH control and optimization of treatment chemistry. Precise dosing ensures ideal pH range for coagulation and flocculation. Safe handling with automated injection compatibility.

pH Elevation

pH Adjustment Base

Liquid caustic for pH elevation and metal precipitation. Essential for meeting discharge pH requirements and optimizing polymer performance. Stabilizes pH throughout treatment process.

Foam Control

Defoamer - Silicone, Non-Silicone

Foam control for treatment tanks, final effluent, and clarifiers. Non-silicone defoamers are safer for filtration membranes.

Clarification

Clarifier Aid - Bentonite

Bentonite can be used in the treatment process as a coagulant aid, to build floc mass, or as a sludge conditioning agent for dewatering. Ideal for high-volume operations.

Metals Precipitation

Metal Scavenger - Inorganic, Blends

Full line of liquid precipitation agents for the removal of heavy metals that can be found in industrial waste streams.
