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

INVENT at the IFAT in Munich

At this year´s IFAT in Munich INVENT has again presented its competences as a global player in the water and wastewater treatment by hosting a giant booth attracting hundreds of visitors from all around the world. Our displayed product portfolio in large and small scale streched the whole range of biological water and wastewater treatment, from air supply to innovative stirring and mixing systems on to efficient aeration technology and an appropriate control system of the same. Our newly launched products iFILT®-Diamond Filter, HYPERMIX®-Agitator as well as the CYBERSLUDGE®-Mixer met with great interest. We would like to thank all our visitors for the interest shown towards INVENT and our products and for inspiring conversations!

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.


INVENT iFILT®, compact stainless-steel diamond filter – high-tech for tertiary wastewater treatment

INVENT made use of their long-standing experience in the sector of water and wastewater treatment as well as their expertise in the fields of fluid mechanics, hydraulics and component design to develop the iFILT®-diamond filter. The newly developed and fluid-mechanically optimized iFILT®-diamond filter meets all demands on continuative treatment steps in communal and industrial water treatment. INVENT therefore makes sure that tertiary treatment steps can be realized in a more economic and large-scale way. Read the press release here. Click here for the iFILT®-diamond filter product page


Hyperboloid Mixers with submersed drive

Complementary to the HYPERCLASSIC®-Mixers with top mounted drive and shaft INVENT offers the submersed driven version. The HYPERDIVE®-Mixers feature the same excellent mixing characteristics and advantages as the top mounted version and can be applied in cases where bridges cannot be realized or submersed driven solutions are preferred.

 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
