INVENT Press Release

INVENT developed the HYPERMIX®-Agitator for efficient mixing in drinking water reservoirs.

Drinking water reservoirs play a central role in the implementation of safe access to drinking water in our cities and communities. The treatment and filtration processes to produce drinking water can be costly, and to ensure the final product to the consumers is of the highest standard, quality must be maintained within the storage facilities. Within the storage facilities the water can deteriorate through “stratification“ leading to undesirable odour and taste variations, as well as critical chemical concentration variations which can result on the delivered water being outside regulatory guidelines.

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.

The construction and the design of the HYPERMIX®-Agitator are based on the successful HYPERCLASSIC®-Mixer that has now been adapted for the use in drinking water reservoirs. For this reason, all the essential parts as well as the mixer-body are made from stainless steel SS 316 as well as the drive that is situated below the water surface and are designed to meet hygienic design directives DIN EN 1672-2:2009-07.

The HYPERMIX®-Agitator has been specifically engineered for quick and simple installation requiring no special tools or equipment. The agitator is lowered through any existing maintenance opening and rests under its own design weight on the tank floor. It is supplied with an external control system that is used for start stop and speed setting. The speed setting can be used for optimizing chemical dosing, allowing the HYPERMIX®-Agitator to provide maximum fluid volume flow during the dosing process. This, in combination with the optional integrated dosing point within the high turbulent zone ensures complete micro mixing prior to distribution to the entire tank contents.
