Wastewater that is discharged into municipal wastewater treatment plants (WWTP) may come from both industries and municipalities. The different loads of the water place the greatest demands on the process control of the WWTP to maintain low contamination of effluent water / treated wastewater which is usually discharged into public waterways.
Monitoring on inlet
- Process control of treatment processes by stable inlet loads
- Process safety and protection of biological treatment (nitrification, activated sludge, aeration) based on incoming loads (biochemical oxygen demand, BOD, and toxicity)
- Anaerobic digestion based on oxygen demand of incoming loads
Monitoring of outlet to control treatment performance
- Organics (TOC, COD)
- Nitrogen and phosphate compounds due to their high nutrient input
- organic trace elements / micro pollutants gain importance in terms of environmental protection
Depending on the region, drinking water from groundwater or surface water is treated by means of chlorine or ozone processes as it usually contains natural organic matter (NOM).
Organics combined with chlorine will create hazardous substances – Disinfection By-Products (DBP)
- Trihalomethanes (THM)
- Haloacetic acids (HAA)
Formation of DBP depends on temperature, water pH, time, disinfectant dose, type and concentration of organics.
Monitoring of inlet water
- Control of source water to ensure product quality
- Dosing of disinfectants based on incoming organic load
- Will reduce risk of DBP formation
Monitoring of outlet water
- Maintain high product quality by monitoring organic content
Germany’s LAR along with their newly appointed Australian distributor will be able to help with any TOC, COD, BOD/Toxicity and Total Nitrates analysers in the most demanding of wastewater applications. Please contact Bintech on 1300363163 or firstname.lastname@example.org for further information.
