General Information

The food industry and beverage manufacturers produce wastewater which is characterized by high COD and nitrogen levels. These loads result in large amounts of sewage sludge and a high energy demand in conventional wastewater treatment plants.

Do you know this problem? Then we have the perfect solution for you. The unique FlexBio wastewater treatment converts these fats and COD loads into energy-rich biogas. This technique significantly reduces the flow of the material and the costly disposal of sewage sludge is all but avoided. You can gain up to 20% of your required energy from your wastewater. We offer solutions for direct discharge and indirect discharge to the adjacent sewage treatment plant. Our effective purification technology helps avoid any heavy pollution charges or other surcharges on the wastewater levy.

We will be happy to answer any further questions in our FAQ!


Example of a compact container plant for wastewater treatment at a beverage manufacturer.

FlexBio wastewater technology purifies the waste water produced by food manufacturers and beverage producers effectively and cost-efficiently. It does not matter whether you produce/process potatoes, juices or beer, the wastewater treatment will fulfill its job at the highest level. The FlexBio systems are offered both as compact and modular container solutions or in a traditional container design. The decisive advantage of FlexBio technology is that our plants are also economical for smaller companies.

The raw sewage is first put through a separator/drum sieve to separate any contaminants and coarse materials. Then the wastewater is stored in a storage tank and homogenized. Subsequently, the wastewater enters the main purification stage of the plant: the high-performance fermenter. Here, the fats and organic compounds are converted into biogas by means of the biological process of Methanogenesis. In this stage, more than 90% of the loads are already degraded. No material flows are created that will need to be disposed of. The purified wastewater is treated aerobically in the downstream second treatment stage. In this stage, the remaining impurities are removed from the wastewater.

The biogas produced can be used as energy in a CHP or a gas boiler and thus exploited as sustainable energy for your business. If necessary, the biogas can also be used for the production of compressed air or cooling.

The system is designed for fluctuating loads. Even strong shock loads are buffered and do not affect the flow values. The flow values can be determined individually and permanently guaranteed by the intelligent process management. Whether you are discharging indirectly and are only required to comply with a COD limit value or whether you need to adhere to certain values of COD BOD5 , nitrogen, nitrates, nitrites, ammonium, phosphates etc. as a direct discharger, the FlexBio portfolio always offers the right solution.
