Know-How

BHU Umwelttechnik GmbH has deep know-how, being predestinated to solve almost every technology and process requirement in water, wastewater and sludge treatment in both dimensioning and implementation. Furthermore, we are using advanced and unique technologies for, chemical-physical, biological and thermal applications.

 

For some applications - such as the high-performance flocculation and sedimentation reactor LHPS -

BHU Umwelttechnik GmbH has issued technological licences in several countries.

 

BHU Umwelttechnik GmbH is highly experienced in LHPS and BAF technology applied to

municipal and industrial wastewater treatment applications.

The StR process furthermore offers holistic treatment possibilities for municipal sewage sludge providing the following advantages:

- highest production of electric power

- production of ashes instead of residual waste

- recovery of nutrients like phosphorous and nitrate as a fertilizer value
