Chemical handling

Correct chemical storage and dosing is essential to the proper operation of industrial and municipal water and wastewater treatment plants. The correct selection of chemicals, chemical dose rate and mixing parameters is critical and has a direct impact on the availability, performance and service life of process equipment.

Traditional coagulants used in the primary treatment of industrial wastewater include Ferric salts, Alum, PAC (Poly Aluminium Chloride), ACH (Aluminium Chloro Hydrate), Bentonite and other proprietary products. The pH of the wastewater is critical to the selection of coagulant and often pH control is incorporated with the coagulation process.


Biological processes need nutrients such as ammonia and urea.


Defoamer is used to prevent foam formation in MBBR and AS process.
