The focus of our activities is on applications in municipal and industrial water and wastewater treatment.

Our product range encompasses the following fields:

Mixing Technology

Water and wastewater treatment plants are usually created as a made-to-measure design and lay-out for a particular project. Depending on the original situation and the intended treatment, various process engineering steps are combined so that the aim of the process engineering is safely within reach. While doing so, the engineer draws from a range of known unit processes. The most important processes from this range are stirring and mixing processes. They play a decisive role in nearly all water and wastewater treatment plants.

Examples for important applications of mixing technology in water and wastewater treatment plants:

Application Mixing task
Mixing and equalization tank Suspension and Homogenization
Neutralization Flash-Mixing
Pre-Mixing of Precipitants Flash-Mixing
Precipitation Suspension and Homogenization
Coagulation Suspension and Homogenization
Biological phosphate elimination Suspension and Homogenization
Denitrification Suspension and Homogenization
BOD or COD removal Homogenization and Dispersion
Disinfection Flash-Mixing
Sludge treatment Suspension and Homogenization
Storage of chemicals/chemical solution      Suspension

Aeration Technology

In the purification of water and wastewater more and more process-technology steps for cleaning and purification are coming into use, which combine to form a complete installation. Processing can be divided into physical, physical/chemical and biological treatment. The biological phase represents the heart of the process. In this phase, carbon and nitrogen compounds are biologically broken down. The basis of this process is effective mixing and the efficient addition of oxygen, so that the biologically active bacteria can work effectively.

INVENT has specialised in exactly this area, and its innovative products make it one of the world’s leading concerns in the field of mixing and aeration technology for water and wastewater treatment.

System Solutions

A complete system solution from INVENT comprises, depending on the customer’s requirements, the basic and detailed engineering, project management, delivery of the mechanical components, installation of the plant, and training of plant personnel.

The mechanical components, such as mixers, aeration systems, pumps, blowers, armatures and instrumentation, control and automation systems, are carefully selected for an INVENT system solution, and co-ordinated with each other.INVENT takes responsibility for the entire scope of the delivery. This approach reduces the number of interfaces and potential sources of failure.
