Treatment of wastewater using a physical and/or chemical procedure including suspended solids settling, or another method that reduces the Biological Oxygen Demand (BOD) of the incoming wastewater by at least 20% and the total suspended solids content by at least 50% before release.

Wastewater and process water treatment are required to safeguard public health and the environment, as well as to keep industrial processes running smoothly. Most regulatory authorities demand regular analytical testing of wastewater effluents at various treatment stages. Process water used in boiler and chiller systems is frequently tested for chemical composition.

Wastewater Analysis Parameters

The most frequently used parameters are: Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Organic Carbon (TOC), Alkalinity, Chlorides, Nitrogen, Oil and Grease, Dissolved Oxygen, pH, Phosphorus, Gases, Sulphur, Solids, Temperature, Metals as well as Micro-organisms.
