Activities and Aims

ERTEL Abwassertechnik Industrie e.K. – founded 2004 – is a family business with a long industrial experience and success in the fields of consulting, development, application and distribution of innovative specialty chemicals and processes.


We are mainly concerned with

  • the treatment and disposal of all types of oil-in-water emulsions, concentrates and oil- and heavy-metal wastewater from the metal, automotive and steel industries and
  • the chemical -process optimization of cost-intensive wastewater treatment plants.

Our objectives are not only to meet and permanently comply with the legally prescribed limit values for waste water pollutants, but also to apply products and processes that do not place an additional burden on water and the environment.

ERTEL Specialty Chemicals, Novel Demulsifiers (Spalter), Heavy Metal Precipitation and Detoxifiers

These products are produced in well-known companies and in contract manufacturing according to ERTEL recipes in Germany and are delivered directly to our customers in Germany and abroad. Only raw materials produced in Germany or in companies within the EU are used for our products. For this purpose, we increasingly use polymers and specialty chemicals based on renewable raw materials.


Our products are characterized by

  • the highest quality and the long storage resistance
  • excellent efficiency and cost-effectiveness and
  • moderate prices.

ERTEL Special Customer Service

We supply the chemical-physical basis for the treatment, detoxification and clarification of industrial and commercial waste water with detailed elaboration of the process, the costs with photos and Know-How for the project planning and construction of new waste water treatment plants and the conversion of old plants.


The waste water of interested customers is examined in our laboratory, the application of our products and processes is tested and the "scale-up" is carried out - i.e. products and processes are carefully selected here and not at the customers.


Due to the versatile tasks and requirements of our customers, such as plant manufacturers, distributors, commercial enterprises and industrial companies, we have now been able to acquire a wealth of experience in industrial applications.
