We donate for clean water

With great commitment and passion we work daily on the purification and treatment of water and wastewater. This year, INVENT again supports ´The Ocean Cleanup´ and for the first time ´One Earth – One Ocean´. These organizations have the goal of freeing water worldwide from plastic waste, oil, and pollutants.



iFILT®-Diamond Filter is PROCESS' Top Product 2018

Readers of PROCESS, the renowned trade journal for chemistry, pharmaceuticals and process engineering, voted the INVENT iFILT®-Diamond Filter in third place among the top products of the year in the category of water / wastewater technology. As a measure of the reader/user response, the numbers of clicks are evaluated on the PROCESS online portal. The digital reach and traffic are controlled by the German Audit Bureau of Circulation (IVW) and are therefore verifiable.

We are excited about the keen interest in our iFILT®-Diamond Filter. You can access the article here.



INVENT HYPERMIX®- Agitator – efficient mixing in drinking water reservoirs

Stratification in drinking water reservoirs impacts water quality. During the stratification process, different water layers with different temperatures occur. There is no fluid exchange between these layers. This leads to longer dwell times for a part of the water and thus to algal formation, subsequent germination and/or uncontrolled chemical concentrations. All this can easily be prevented by the implementation of the HYPERMIX®- Agitator. This mixing system helps to displace the water layers and to prevent them re-forming. More information

Product innovations for mixing systems

INVENT is going to present two product novelties in the field of industrial mixing at IFAT. The INVENT CYBERSLUDGE® is a mixing system that features a fluid mechanically optimized design and was designed for the mixing of the waste sludge in the digester. The INVENT iBC-MIX® is designed for the continuous operation in steel caged IBC, tote, or pallet tanks and liquids of different composition, viscosity, and rheology. Read more.


 Beverage industry - water technology according to purity law

Plants that clean wastewater, for example in beer or mineral water production, are among the specialties of INVENT. The legal requirements vary by country and location. "If a brewery is located in the middle of the city, it can often direct its wastewater directly into the municipal sewage system," explains Dr.-Ing. Marcus Höfken, Chair of the Board at INVENT and Chair of the VDMA Water and Wastewater Technology Group. "The brewery must then follow the rules for an indirect discharger, which means that it drains water into the sewage system and must be able to store the wastewater temporarily." Read more  


Wastewater treatment in breweries – INVENT’s process engineering solutions

Wastewater coming from breweries is biologically and chemically heavily contaminated, the most important parameters being the biochemical oxygen requirement and sulfides that, when inadequately areated, can lead to olfactory problems (hydrogen sulfide). The federal government’s central wastewater processing agency stipulates strict maximum permissible values for the direct discharge of a brewery’s wastewater. Indirect discharge facilities are subject of different permissible values, varying partly depending on the specific communities. In any case, compliance with the permissible values is highly relevant for wastewater treatment plant operatorsin the vicinity of a brewery. Read press release
