BHU Umwelttechnik GmbH received the order for the design, engineering and installation of a river water treatment system with a capacity of 800 m³ / h in a paper mill in Poland. The system comprises a high performance precipitation system (LHPS) prior to existing sand filtration units. The task is to decrease especially suspended solids and dissolved organic compounds. Thus, fouling in the existing production line will be reduced tremendously. BHU Umwelttechnik GmbH will be the general contractor.
We are pleased to report on the receipt of the next new order in the German industrial sector.
The third major order of the year 2019 was given to us by a german sugar manufacturer. The anaerobic wastewater treatment for the processing of beet wash water is designed for a capacity of 45 t / d COD. The plant converts 95% of the organic wastewater load into biogas.
BHU pilot plant for biofiltration
2 filter columns each with 307 mm inner diameter and 4000 mm total height
Height of filter material fill: 3000 mm
Filter direction: from bottom to top;
Feed rate: 280 - 850 L / h
Air volume Process aeration: 1 - 10 L / min
We are pleased to report on the receipt of two new orders in the German and European industrial sector.
The first major order of the year 2019 was given to us by a paper factory with several plants in southern Germany. The BAF biofiltration plant, with a capacity of 700 m³ / h, will be installed as a tertiary purification stage in the construction of a new wastewater treatment plant. The plant essentially serves for the further removal of the COD after previous full biological cleaning.
The process has been used successfully for many years in various paper mills. Nevertheless, a semi-industrial pilot plant was built in advance for the large-scale plant. The pilot plant has just gone into operation.
The second major order of the year 2019 was given to us by Südzucker AG for the Polish sugar factory of Strzelin. The anaerobic wastewater treatment for the processing of beet wash water is designed for a capacity of 25 t / d COD. The plant converts 95% of the organic wastewater load into biogas.
In total of these two projects, order intake in 2019 is already more than 3.5 million Euro.
BHU Umwelttechnik is now part of the ALMAWATECH Group
We are pleased to announce that BHU Umwelttechnik is now part of the ALMAWATECH Group. In February 2019, a participation agreement was concluded whereby ALMAWATECH Holding acquires the majority stake in BHU Umwelttechnik.
The management of BHU Umwelttechnik continues to consist of Stefan Köppl and Dr. Ing. Alessandro Meda. Both managing directors continue to hold shares in the company. The company will continue to operate independently in the European and Asian markets. The successful BHU subsidiary based in Qingdao, China is also part of the new stake.
Together we can be stronger - that is the motto and the goal for the long-started cooperation in special customer projects. Thanks to the cooperation between ALMAWATECH and BHU Umwelttechnik, there is hardly any process or technology in industrial water and wastewater technology that we can not offer our customers.

We are pleased to announce that our application has been approved as part of the joint project BMBF project Client II on 01.09.2018.
The project PIRAT-Systems - Energetic Process Optimization and Implementation of Resource Efficient Wastewater Technologies on Municipal Wastewater Treatment Plants – is a German-Chinese research project which supports both education through the support of five German universities, Tongji University in Shanghai, China Agriculture University Beijing and other well-known Chinese industrial companies , to strengthen research and innovation in Germany and China as well as to support the competitiveness of German companies.
Cooperation with emerging and developing countries in the field of research and development enables Germany to assume international responsibility in dealing with global challenges. In addition to ensuring a high degree of innovation dynamics, the project not only incorporates technological but also socio-economic and ecological aspects. The aim of the support project is to make a positive contribution to global climate protection, on the one hand through the efficient and intelligent use of natural resources, but also by creating incentives to reduce the environmental impact in the partner countries.
The aim of the project is to develop concepts and system components for resource-oriented, energy-efficient wastewater treatment for China, to provide design approaches, planning tools and market strategies, to show transitional paths and to gain acceptance among operators, authorities and the population. Innovative technologies for combined phosphorus removal and recovery, energy-efficient nitrogen elimination, co-digestion and energy efficiency on wastewater treatment plants are being adapted to the Chinese boundary conditions. In addition, the operation of test facilities on a laboratory scale improves the process understanding of the investigated innovative technologies and tests and adapts typical operating conditions in pilot plants. By modeling, embedding and simulating in SIMBA #, design approaches can be developed and, in a further step, these innovative technologies can be combined. Concepts are being developed which point out the transition steps towards a resource-oriented, energy-efficient treatment plant.
In order to get closer to the goal of a more energy-efficient sewage treatment plant, the necessary adaptation measures and extension stages for the successful and economically viable establishment of anaerobic sludge treatment - as a central component of energy and resource-efficient process optimization - are to be investigated. An essential element in this context is the extensive and energy-efficient nitrogen elimination, especially with regard to the upcoming new discharge standard and the nitrogen back-loading with the integration of sludge digestion. The work package "Energy-efficient nitrogen elimination" is led by the BHU.
For a selected large-scale model wastewater treatment plant, detailed planning and design parameters for the extension of the existing waterline are created by a deep sand filter for denitrification as far as possible and integration of the side-by-side nitrification / denitrogenation process.
The Top Harvest Yanchang Coal refinery wastewater treatment and recovery plant in Yan'an, Shaanxi Province, People's Republic of China was commissioned in early August. The plant consists of two main lines for the purification of highly polluted process wastewater as well as the slightly polluted mixed wastewater
with a capacity of just under 20,000 m³ / d each.
The planned recovery rate from both main lines is more than 70% overall. The treatment chain includes the following sub-processes: flotation, biological main cleaning with a two-stage activated sludge process, precipitation, flocculation and sedimentation (BHU reactor LHPS), oxidative treatment with ozone, biofiltration (oxic / anoixic - BHU reactor BAF), biological polishing by means of BiosS-Treat ® Filtration, Ultrafiltration (UF), Reverse Osmosis (RO), Concentrate Nanofiltration (NF); Activated carbon filtration.
BHU has carried out the conceptual design of the entire plant as well as the detailed design of all process stages except the membrane stages. BHU has also supplied key procedural components to these stages and is also responsible for monitoring installation and commissioning.
