ETP & STP Water Treatment Chemicals

Wastewater-treatment chemistry for clarification, biological treatment, sludge handling and discharge-quality control.

Wastewater chemistry

Coagulants

Alum, PAC, lime and application-specific coagulants support solids and colour removal.

Polyelectrolytes

Cationic and anionic polymers improve floc formation and sludge dewatering when selected by jar testing.

Biological cultures

Specialised cultures and nutrients can support biological start-up and process recovery.

Defoamers & odour control

Manage process foam and odour while investigating the underlying hydraulic or biological cause.

Jar testing, wastewater characterization and process conditions should determine the product and dose; there is no universal wastewater dose.
