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.

INVENT successfully attended WEFTEC 2017, Chicago, USA

This year’s WEFTEC took place in Chicago from October 2 24 to 4. INVENT put its entire range of products on display: from efficient stirring technologies to innovative aeration technologies and complete system solutions for almost any requirement in municipal and industrial water and wastewater treatment. INVENT looks back on a successful participation, pleased about the large quantity and very high quality of contacts that could be established. 

The INVENT team is grateful for all of its visitors’ display of interest . We’ll see you again next year at WEFTEC 2018 in New Orleans!

Coagulation and flocculation in the Helsinki drinking water treatment plant

The raw water for Finland’s capital Helsinki is pumped from Lake Päijänne, located approximately 120 km away, via a tunnel to two water treatment plants. This secures sufficient drinking water of excellent quality for around one million people. In the drinking water treatment plant in Vanhakaupunki 18 HYPERCLASSIC® Evolution7 mixers and three CYBERPITCH® mixers made by INVENT have been in operation since July 2017. Read full press release 

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
