The challenges of wastewater treatment

Mechanical, biological and chemical processes are used to clean water pollutants at wastewater treatment plants. Exhaust air purification processes at wastewater treatment plants may be necessary if odours have a negative impact on the environment. Exhaust air treatment is mainly used for odour-intensive plant components such as the inlet pumping station, the screen house, the grit chamber and sludge treatment.

Our solution

Various types of exhaust air purification systems can be used. These include scrubbers, biofilters and activated carbon filters. A combination of technologies is also possible. Which system is used here depends on the conditions on site (space available, desired cleaning performance) and the type of wastewater treatment plant (municipal wastewater treatment plant, industrial wastewater treatment plant). We will be happy to advise you!

We provide you with expert advice and support throughout the entire project. From checking the functionality and assessing the overall system to regular maintenance – we ensure that your system always runs optimally.

Icon High operational reliability and long service life of the system
High operational reliability and long service life of the system

We manufacture our products from GRP. Glass fibre reinforced plastics (GRP) are made from reinforcing materials (glass fibre mats, fabrics, etc.) that are impregnated with various resins and chemical additives. This has many advantages: low weight with high resistance, non-porous and easy-to-clean surfaces, good thermal insulation values and low thermal expansion.

Icon High savings in energy and operating resources
High savings in energy and operating resources

The optimisation of production processes, the use of energy-efficient machines and systems and the implementation of intelligent control and monitoring systems can significantly reduce energy costs. The economical use of resources such as water, raw materials and packaging materials also helps to conserve resources and reduce environmental pollution. We attach great importance to this, both in our own production and in the planning of your systems.

    Concepts implemented worldwide
    for wastewater treatment

    wastewater treatment plant Cottbus

    Cottbus wastewater treatment plant / Germany

    Odour removal with biofilter

    For the Cottbus wastewater treatment plant, a biofilter was installed as a compact system for the treatment of 1,500 m³/h of exhaust air from the sludge feed tank, centrate storage tank, pump feed and mechanical sludge dewatering. A second biofilter cleans the exhaust air (350 m³/h) from the mixing tank. This is also designed as a compact system with pre-scrubber.

    wastewater treatment plant Zossen

    Wastewater treatment plant Zossen/Germany

    Exhaust air purification with activated carbon filters

    At the Zossen sewage treatment plant, 4,200 m³/h of H2S-contaminated exhaust air is extracted from the enclosed screening hall and cleaned. The exhaust air is drawn in with a fan and cleaned in an activated carbon filter. This is installed in the outdoor facility.

    In a second plant, the exhaust air from a covered pre-treatment system is treated. Here, 1,400 m³/h of H2S-contaminated exhaust air is cleaned in an activated carbon filter.

    wastewater treatment plant Tubli

    Tubli/Bahrain wastewater treatment plant

    Complex plant in the desert

    The wastewater treatment plant in the city of Tubli in Bahrain has been expanded and an exhaust air purification system installed. The exhaust air is drawn from the following sources using fans: sand trap, pumping station, screen, sludge silos and equalisation basin. A total of 72,000 m³/h of exhaust air is channelled into the cleaning system. The exhaust air first goes into an alkaline-oxidising scrubber, which is operated with ozone and caustic soda. The exhaust air is then dehumidified using a heat exchanger. Fine cleaning then takes place in activated carbon filters. As there are only limited resources available at the wastewater treatment plant site, a heat pump is used to provide the hot and cold water required.
