What a wastewater treatment system is
According to DIN 4045, wastewater systems are facilities for collecting, treating, conveying and disposing of wastewater. Companies that produce contaminated wet sludge need them to comply with statutory discharge limits, protect the environment and reduce disposal costs.
- Reliable
- Designed for trouble-free continuous operation day to day
- Made to measure
- We build the system to suit your wastewater and your space
- Economical
- Low operating costs, less sludge, lower disposal costs
How our systems work
The systems operate largely automatically. A level-controlled diaphragm pump transfers a batch from a buffer tank provided on site into the reactor vessel. The flocculant is added while stirring; the solids are bound and settle after about 15 minutes. A turbidity measurement determines where the clear water phase goes: if it is turbid, into the sludge thickener; otherwise via the gravel filter and the final pH check (with printout) into the sewer. The sludge phase is conditioned in the sludge thickener and then dewatered with a chamber filter press.
Sequence of a batch:
- The wastewater flows into the reactor via a pump or by gravity until it is full.
- The stirrer starts.
- The coagulant is added.
- After the set time, the stirrer switches off.
- The flocculated dirt settles.
- The clear water valves open and the clean water drains off.
- Residual water and sludge drain via the sludge outlet.
- Clear water and sludge water are passed through special filters in dewatering containers. The sludge remains entirely in the filter.
- The filtrate is collected in the water collector and can be reused or discharged into the sewer.
The world’s smallest wastewater treatment system: CA10
The CA10 treats 10 litres per batch. It has an electric stirrer rated at 250 watts with up to 2,650 rpm; filtration takes place through a dewatering container with a waterproof disposable filter. Light and compact, it is also suitable for small workplaces.
Systems in practice
Emulsion splitting plant
Treats contaminated wastewater from almost all industries. Throughput 300 litres per hour; dewatering takes place via filter bags and a drip tray.
Neutra neutralisation plant
Compact plant for batch or continuous neutralisation, modular in design and fully automatic with a freely adjustable sequence. Throughput is infinitely adjustable, and the discharged limit values are recorded without gaps. The plants are enclosed to be odour-tight and are intended for installation in frost-free rooms.
Applications: commercial kitchens, beverage and food industry, dairies, electroplating, dye works, pickling plants, slaughterhouses, metalworking.
Sed chemical-physical treatment plant
For treating wastewater with a high pollutant load and complex dissolved substances, in an energy-saving, user-friendly automatic design.
Gravel filter plant
Physically removes undissolved solids and suspended matter from the liquid. As the filter medium loads up, the differential pressure rises. Once a limit value is reached, backwashing is triggered automatically.
Polymer make-up station
Prepares polymer solutions from dry or liquid raw materials. Precise flow measurement for solution preparation and level measurement ensure economical, reliable operation.
