Industrial Wastewater


Whether you discharge wastewater in municipal sewage plants or operate your own sewage plant – we offer comprehensive solutions for your company’s individual sewage problems. Apart from chemical-physical and mechanical solutions, we specialise in biological wastewater treatment.


We are producer-independent and recommend only what you need for your wastewater treatment, water purification and waste treatment. We are happy to counsel you on the various purification procedures, limiting values and the operation of your sewage plant.


We help you find your way through environmental law, legislation and regulations, so your company is perfectly on the safe side. We gladly take care of your wastewater reports, licensing procedures, and obtaining subsidies, and we support you in external controls.



Salzmann Ingenieure’s expertise is invaluable for us, as ongoing support and especially in planning new structures. They help us ensure that our production runs sustainably and at optimal costs.
