Abwasser König

For optimizing costs and operations Abwasser König is offering the analysis and preliminary assessment of the company wastewater. If you are interested you can book first consultation at the Brau Beviale. 

Following a check list especially developed for food and beverage production the analysis can be realized on-site in one day. It includes water supply and use, production conditions and material input, wastewater treatment plants of the company, fee situation, waste water and polluting load, municipal and legal frame conditions as well as cooperate planning. 

Shortly after the evaluation of the results will be given in a report. It shows the need for action in the different sectors. Assignment of tasks following the analysis are for example:

- reducing the volume of wastewater and polluting load

- negotiations with the municipality to adapt the requirements, costs or fees

- adapt planned sewage works to the requirements

- examination of alternatives to in-plant wastewater treatment

- optimizing of in-plant sewage works

Manufacturing processes in the food and beverage industry produce organically highly polluted wastewater. Depending on the volume of wastewater, effluent pollution, requirements for wastewater discharge and fee situation Abwasser König provides adapted solutions. 

One of the most important things is the analysis and evaluation of the assignment of tasks in a neutral way without being dependent on the interests of manufacturer. Because of that the techniques that are available at the market are to be used considering the frame conditions. 

When it comes to upcoming investments in the wastewater treatment, Abwasser König is your partner for planning. Your projects will be worked on extensively from basic evaluation, rough and detailed planning, approval procedure, call for bids, assignment to approval and technical documentation. 

Depending on type and size of the project as well as the clients requirements execution will be done through specialized plant manufacturer, through local already introduced installation companies or through the client himself. 

The extent of planning will be adapted to the approach wanted by the client. 

For existing purification plants the goal is to minimize the running costs and still ensure a stable system while using the existing technology and considering the influences on the quality of the wastewater. Malfunctions should be eliminated or corrected as fast as possible. 

In this process Abwasser König gives advice about purification plants of different producers. They specialize in optimizing purification plants following the SBR-System. 

For eliminating weak points and optimizing wastewater treatment plants various measures can be needed depending on the frame conditions. 

Some examples are given in the following:

- immediate actions to eliminate malfunction

- reworking of the process and plant management of the sewage treatment works

- adapting the control and regulating processes

- adapting of the systems engineering

- determine needed maintenance and monitoring work

- instructing the staff in plant management

- provide manuals for the purification plants

- reduce the volume of wastewater produced by the company

-  limiting wastewater loads through in-house measures

- improving the quality of the wastewater in terms of the operating purification plant

- hotline for the staff of the plant

Goal of the pretreatment of wastewater in the food and beverage industry is to meet the requirements of local statues of dewatering:

- pH-value: 6,5 to 9,5 

- temperature: below 35 °C 

- restriction of COB concentration

- restriction of COB load

- restriction of wastewater volume

Depending on the frame conditions Abwasser König plans the following plant types for the pretreatment of wastewater:

- neutralization plants

- ventilated tanks for blending and balancing

- aerobic (aired) biological systems for wastewater pretreatment

- anaerobic biological systems

For aerobic systems discontinuous SBR-plants, continuous processes with final sedimentation, membrane bioreactor and fixed bed plants are used. For anaerobic systems upflow reactors with grained biomass as well as fixed bed systems have proved themselves. 

Goal of wastewater treatment is to meet the requirements for direct discharge of the purified wastewater in water bodies. For wastewater from the food and beverage industry this usually means meeting the following critical values:

- biochemical oxygen demand in five days (BOB₅) below 25mg/l

- chemical oxygen demand (COB) below 110 mg/l

- ammoniac nitrogen (NH₄-N) below 10 mg/l

- nitrogen, total of ammoniac, nitrite and nitrate nitrogen (N_tot) below 18 mg/l

- phosphor, total below 2 mg/l

Depending on frame conditions Abwasser König is planning 

- aerobic (ventilated) biological systems for wastewater treatment

- anaerobic biological systems in combination with aerobic systems

  for wastewater purification. 

For aerobic systems discontinuous SBR-plants, continuous processes with final sedimentation, membrane bioreactor and fixed bed plants are used. For anaerobic systems upflow reactors with grained biomass as well as fixed bed systems have proved themselves. Anaerobic systems need finishing treatment to meet the critical values for direct discharge.
