One of the most costly aspects of a production process is the interruption of work due to unexpected maintenance. Find out how to prevent this here.

Scaling (inorganic and organic hard buildup) is a common problem in the industry. It can cause blockages in pipework or other systems.

From complete blockage in three months to years of clean piping.

This floating pontoon, established in 1974 carries out measurments 24/7 to ensure the appropriate waterquality. The measurment probes need to stay completely fouling free.

Seawater plays an essential role as a medium for the efficient operation of various technical functions of a vessel. Unfortunately, the seawater for technical installations contains various impurities that must be filtered out.

INVENT uses the example of a large manufacturer of paper and cardboard products for the pulp and paper industry to show why they are the ideal solution for wastewater treatment in this industry.

The joint wastewater association Staufener Bucht, Germany, has placed its trust in the hyperboloid mixing technology of INVENT Umwelt- und Verfahrenstechnik AG.

One of our leading products ensures reliable mixing in the flocculation basins of a drinking water treatment plant in the Southeastern USA.

Submerged aeration systems are ubiquitous in modern wastewater treatment plants, dispersing bubbles of air below the water surface enabling the transfer of oxygen to the water for the growth and activity of the treatment bacteria.

In recent years, the HYPERCLASSIC®-Mixing and Aeration Systems have been developed into complete solutions for the industrial and municipal wastewater treatment.

Fluidmechanically optimized INVENT mixing and aeration systems have been providing reliable wastewater treatment in an industrial park on the Danish island of Zealand since 2016.

The wastewater treatment plant in Dordrecht, Netherlands, relies on INVENT’s hyperboloid technology. Back in 2005, 22 HYPERCLASSIC®-Mixers were installed at the municipal wastewater treatment plant.

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).
