Industrial WWTP

Technology of Industrial WWTPs

The SBR technology from TopolWater for industrial wastewater treatment plants is particularly applied in the food industry, where the production and processing of food result in heavily organically contaminated wastewater. For each industrial sector and every operation, it is individually designed according to the investor’s data.

• Each treatment plant is equipped at the inflow with safe and efficient mechanical pre-treatment, which includes manual or mechanical screens for removing all larger particles and coarse impurities
• The next step is usually homogenization, which consists of a tank of suitable volume with a mixer, where the quality and quantity of incoming raw water are balanced and prepared for further cleaning
• The parameters of the incoming water are measured and if necessary, further adjusted. For example, pH measurement and subsequent neutralization, measurement of nutrients (N, P), and addition of chemicals to adjust the concentration suitable for further biological treatment
• If the organic pollution of the wastewater is very high, chemical-physical pre-treatment can be designed as the next step. This involves the use of dissolved air flotation (DAF), supplemented by processes of chemical coagulation and flotation. This technology reduces the pollution to parameters acceptable for biological treatment
• This is followed by biological SBR reactors to treat the remaining organic pollution. They are usually specifically adapted to the required operating parameters
• For large-capacity industrial wastewater treatment plants, sludge management technology is usually designed. This often includes sludge stabilization in aerated sludge tanks, supplemented by mechanical sludge dewatering, where the volume of produced sludge is minimized. These technologies can include, for example, a sludge centrifuge, sludge thickener, screw press for screenings, etc.

Technological Line Typically Consists of the Following Stages:

• Mechanical Pre-treatment – mechanical screens, sieves, etc.
• Chemical Pre-treatment – homogenization, neutralization, flotation, coagulation, nutrient dosing
• Biological Treatment in SBR Reactors
• Tertiary final treatment – filtration and disinfection
