sewage treatment plants

for gastronomy, trade and community for municipal and industrial waste water for separate and for mixed water sewerage up to approx. 5,000 population equivalent

Our sewage treatment plant types BioTopp, B2000 and MULTOX are optimized for use with municipal and commercial wastewater and are also suitable for our modules for recycling use. We also offer support, repair and optimization of small sewage treatment plants, decentralized municipal sewage treatment plants and industrial sewage treatment plants.

BioTopp sewage treatment plants from 50 to 5000 inhabitants

Our BioTopp sewage treatment system is ideal for small, semi-central or municipal systems with separate sewage systems. The decisive cost advantage is the low investment costs, which result from the significantly reduced space requirement. The process is designed for extensive denitrification and also achieves increased biological phosphorus elimination without an additional anaerobic tank. This saves additional waste water fees, operating costs and protects resources.

advantages

Lower investment costs for containers, excavation and transport due to the 30 - 60% lower reactor volume compared to conventional single-stage SBR plants. Odorless operation and significantly longer concrete service life thanks to aerobic process control, which also means that no faecal sludge and no hydrogen sulfide are produced. €200 - €500 Annual operating cost savings thanks to BioTopp sludge humification, as no faecal sludge has to be removed with a vacuum truck. Best biological cleaning performance through nitrification (cleaning class N) and denitrification (cleaning class D). Increased biological phosphate elimination without the use of chemical precipitants (cleaning class P)

Structure of the system:

description

The BioTopp system is a modified two-stage SBR process with an upstream optional aerobic denitrification reactor with integrated buffer storage, a self-cleaning raking or screening device and an obligatory aerobic sequential batch reactor (SBR). The aerobically stabilized and coarsely screened excess activated sludge is earthed as a thin layer on a drying bed, washed and sanitized by the weather and mineralized by biological degradation.

B 2000 procedure from 50 to 5,000 inhabitants

Our B 2000 process is equally suitable for separating and mixed systems from 50 to over 5,000 residents.

Thanks to the innovative buffering of the intermittently occurring waste water and the automatic adjustment of the aeration to the respective load, the B 2000 process produces excellent and stable discharge values, which are comparable to those of large, state-of-the-art municipal sewage treatment plants.

advantages

Very high, stable cleaning performance at any time of the year.Insensitive to strong load fluctuations.Automatic adjustment of the oxygen input to the current load.Precise limitation of the discharge quantity in the case of weak receiving water possible (option)Precisely defined inflow quantity adjustable (both in mixed systems and in small systems)Targeted nitrate elimination ( Denitrification)Controllable phosphate eliminationDue to the integrated buffering, no design for the maximum load is necessary. No odor emissions. Separation systems are the future.

1. Absorbing shock loads

The B 2000 process works with an integrated buffer in which all basins are dammed up. In this way, fluctuating effluent surges can be collected without any problems and fed straight to the biological treatment.

2. Automatic ventilation adjustment

The aeration is adjusted automatically via the water level in the system. If more wastewater flows into the system than is drawn off, the wastewater level rises (buffering). The varying water level is thus a measure of the current load on the system. If the lower limit water level is reached, the base load ventilation is automatically activated. If the water level rises again, normal ventilation switches on.

In addition to saving energy, a targeted elimination of nitrate is also achieved. All the signal transmitters required for the volume-proportional dosing of precipitating agents for phosphate precipitation are already available, so that later expansion is possible without costly retrofitting.

This nutrient removal, which up until now has mainly been carried out in large plants, can now also be carried out in smaller units with simple means. This represents an important element with regard to improved environmental protection, even with decentralized wastewater treatment.

Systems of the B 2000 series can be operated with and without mechanical pre-cleaning. The raw sewage flows directly to the biological treatment, so that the degradation process can take place without any odor emissions. This preferred system variant has at least two activated sludge tanks connected in series.

MULTOX sewage treatment plants for industry and trade

The MULTOX sewage treatment plants for industry and trade are high-performance sewage treatment plants for industries with heavily polluted organic waste water. The MULTOX system is an activated sludge process that combines the advantages of conventional multi-stage plants with the simplified process and reduced costs of single-stage plants.

advantages

Suitable for high fluctuations in pollution and waste water load. Suitable for batch operation.High operational safety thanks to double protection of the devices.Cleaning class as required up to denitrification and phosphorus elimination.High process stability.No mechanical pre-treatment required.No odor nuisance.Composting of the sludge or its use in agriculture is possible.

description

The MULTOX system enables the economical construction of three to five cascade aeration tanks for the treatment of industrial wastewater with a high organic load. The system has a special process management to achieve cleaning levels of more than 99% BOD and to ensure high process stability. The system can be variably adapted to changing process conditions and easily enlarged.
