Information
Increasing water scarcity in the world calls for sustainable solutions in the face of drought, population growth and outdated infrastructure. BHU Umwelttechnik GmbH offers state-of-the-art technologies, processes and systems for water treatment, wastewater and sludge treatment.
BHU Umwelttechnik GmbH covers the entire spectrum of processes and technologies for water and sludge treatment for municipal and industrial applications - for new plants as well as for upgrading existing establishments. Our know-how makes us a reliable partner who supports you in all phases of the project, from the planning through to the ready-to-operate plant.
Our Homepage provides you an overview of our range of services and our core competencies in the areas of process engineering and project management for water technology plants.
Our engineers specialize in the physical, chemical, biological and thermal aspects of water technology processes, providing you with the best possible solution for your job. We determine the optimal treatment stages and integrate them into a holistic, technically and economically optimal plant.
The know-how and many years of experience of our employees enables us to process all types of water resources and to produce the desired water quality. Our in-house technology spectrum offers the necessary prerequisites for this.
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
