Products & Services

Water Clarification

Clarification systems separate suspended solids from water, with primary clarifiers removing settleable materials and secondary clarifiers further polishing the effluent after biological treatment.
Anaerobic Digestion

Anaerobic digestion uses bacteria to break down organic matter in the absence of oxygen, reducing sludge volume and generating renewable biogas as a byproduct.
Biological Treatment

Biological treatment processes use microorganisms to degrade and remove organic contaminants from wastewater, ensuring compliance with environmental discharge standards.
Headworks

Headworks systems are designed to remove large solids, debris, and grit from incoming wastewater, protecting downstream equipment and ensuring efficient plant operation.
