About WEHRLE Umwelt GmbH

Since 1982, WEHRLE Umwelt GmbH, a subsidiary of 1860-founded WEHRLE WERK AG in Emmendingen/Germany, has specialised into the treatment of complex waste waters. Treated effluents are landfill leachate up to industrial waste waters, for instance from food & beverage, chemical, pharmaceutical, petrochemical and, finally, manure and digestate. The focus is not only the cleaning of waste water, but also product re-use (e.g. for petrochemical industry), water recycling and heat recovery (e.g. for laundries) or energy Generation (e.g. animal rendering, slaughterhouse).

For this, WEHRLE delivery part or turn-key plant along with supporting service like lab testing, piloting, engineering, commissioning and plant optimizing even of plants of 3rd party suppliers.

Customers are not only local counties and companies, but also international customers like Unilever, Mondelez, Novartis etc. Up to now, the company built 300 reference plants worldwide. WEHRLE is pioneer and technology leader for several innovative processes, for instance, the first industrial-size membrane bioreactor (MBR), the first Nanofiltration (NF), the first Low-Energy MBR etc. The plants differ from most other industrial wwtps by exceptionally high reliability, flexibility, very simple operation and maintenance and the most compact design possible with MBRs using external membranes – all important criteria for industrial production plants in various climate regions and changing production waste water.
