Overview of our Products

MADE IN GERMANY since 1976

Modern Manufacturing and all products with high-quality robust construction in stainless steel grant a flawless quality. We provide project-related consulting; moreover, we research and develop constantly to the purposes of reliable, durable and largely maintenance-free systems!

Coarse solids retention

Coarse solids retention

In channels where combined sewage and storm water are conveyed, there are also some coarse substances, such as grit and sewage related debris. These coarse substances usually move more slowly than the water flow and often cause problems with downstream plant and equipment. In principle the goal is to identify the sources of grit or debris entering the sewerage system and eliminate them to prevent sewage related debris within the sewer system.


Combined sewer overflows

Combined sewer overflows

With strong rainfall get a lot of solids unfiltered about the discharge thresholds and the following structures (sewage treatment plant) or onsite preflooders get dirty. The in the following explained equipments like the pump action screen and the lamella baffle can decrease this. They hold back the incoming swimming and suspended matter efficiently without hindering the discharge process in the sewer.


Equipment & Accessories


Flow regulators

Flow regulators

Storm detention systems are required in order to prevent the hydraulic overloading of sewerage networks and the waste water treatment plants at the end of the line. The task of these systems is to provide a buffer for the considerable amount of rainwater produced in wet weather conditions and to regulate its onward flow in a controlled manner. Low control systems are required to protect items of equipment located downstream and also to ensure constant flow out of the storm detention system. Only a thoroughly tried-and-tested flow control system can achieve the desired result of ensuring a constant flow, regardless of the water head within the storm detention system.

Flushing systems

Flushing systems

The BIOGEST- flushing systems have been developed to overcome the problems cleaning storm water tanks that cannot be designed to self clean or where the use of conventional systems such as flushing gates, tipping buckets and jets etc. would compromise either health and safety or efficiency. The BIOGEST-flushing systems solves this problem simple and with an effectively cleaning!


Gate Flushing System


Penstocks, slide-, gates - or sluice - valves


Sludge treatment

Sludge treatment

The development of the CROWN-disintegration system offers sewage plant operators an innovative solution to minimise the sludge quantities to increase the biogas yield and to improve the stability and reliability of the process. From both an economic and an ecological point of view, the CROWN-disintegration system constitutes an investment in the future of modern sewage treatment.


Tank and sewer cleaning


Wastewater treatment

Wastewater treatment

BIOGEST AG realizes biological wastewater treatment plants in accordance to the SBR-process (“Sequencing-Batch-Reactor”) for the treatment of sewage. The CROWN-surface aerator and the CROWN-decanting system are equipments of sewage treatment plants.
