Waste Water / Sewage Technology

For holistic water management, the reliable treatment of all types of waste water prior to its discharge into the environment is of crucial importance. So it is a logical step for ENREGIS to integrate this field of technology into the company and to work in a strategic cooperation with Steinbeis-Transferzentrum Meschede under the direction of Prof. Dr.-Ing. C. Schuster in order to develop and offer process concepts and products for the treatment of wastewater.

The Steinbeis-Transferzentrum Meschede is part of Steinbeis GmbH und Co. KG für Technologietransfer in Stuttgart, with a focus on the development of innovative processes in water treatment and waste water treatment. The basis of this activity is founded on decades of experience by their employees as well as the application of this knowledge in the development of processes and technologies.

Concepts are then verified with the help of a modern laboratory on the basis of representative water and sewage samples. On basis of this, ENREGIS implements all types of waste water treatment plants, from process development and planning, delivery and construction, right through to the turnkey system.

Practice areas

Industrial waste water

Industrial waste water is characterized by mainly high levels of contamination. This is caused by various combinations of different ingredients. Therefore, process development based on laboratory tests in combination with many years of experience by our partners is a prerequisite for the successful process development, engineering and finally the treatment of complex waste water streams. The focus of ENREGIS is on a wide range of applications that covers a wide range of industries.

Chemical industry

  • - pharmaceuticals industry and cosmetics
  • - plastics and dispersions
  • - inorganic production
  • - tensides and detergents
  • - plant protection products
  • - colors and pigments

Food industry

  • - oils and fats
  • - drinks
  • - abattoirs and meat processing
  • - refining of oil (for culinary applications)
  • - delicatessen and canned food
  • - milk and dairy manufacturing

Oil extraction and refineries
Pulp and paper industry

Highly-contaminated rain water

With classic, standard rain water treatment systems such as sedimentation plants, lamellar sewage treatment plants and even standard substrate solutions heavy poluted rain water cannot be cleaned or treated due to high or very specific contamination. These subjects are the focus of this business unit. This type of contamination is often the result of precipitation discharges from highly contaminated areas such as industrial properties, contaminated sites, landfill sites, green waste utilization areas as well as contaminated runoff from agricultural land (silage). Here, substances are often dissolved and introduced into sewers or receiving waters, not only during heavy rain events.

Sedimentation and separation systems
The drainage of industrial areas, motorway bridges, airports and other traffic areas places extremely high demands on the treatment of surface runoff.

ENREGIS/Vivo® TRP, with a nominal capacity of up to 450 l/s, is a safe alternative for these demands and/or an optimal extension of central and decentralized rain water sedimentation tanks (RKB). As a two-system or three-stage system, connected individually or with other systems in parallel, several tens of thousands square metres of surface area can be safely drained and treated, not only for new plants but also for retrofitting older plants.

Grey water treatment

European standard 12056-1 defines grey water as sewage-free, slightly polluted wastewater, for example, water which is flushed away when showering, bathing or washing hands. However greywater also comes from the washing machine and can be treated for secondary use, for the preparation of water for industrial use and/or process water, e.g. through the use of water recycling systems. As a rule, the cleaning is carried out in a purely mechanical/biological way; Recently, bio-membrane filters have also been used. The clear water which is produced in this way is hygienically clean. It can be used for garden irrigation, house cleaning and toilet flushing; even laundry can be safely washed (if prepared to bathing water quality, as is common in Europe). For a household of 4-5 people, the savings add up to about 90 m³ of water per year. In contrast to the weather-dependent use of rainwater, treated industrial water is always available.
