[...]During dry weather, organic and inorganic sediments increasingly settle on the sewer base in combined sewer systems due to slow flow velocities. Under stormwater conditions, these sediments float up and arrive along with the sewer flow at the sewage treatment plant or stormwater overflow structure. If the combined sewer volume exceeds the capacity of the overflow structure or sewage treatment plant, the combined water is frequently discharged to a receiving water course, impairing water quality with the result of increased costs for maintenance and cleaning. As a preventive measure, coarse material[...]

[...]Using the thermal energy of process water to reduce operating costs Much of the industrial wastewater comes from the food production sector: slaughterhouses, breweries and beverage industry, distilleries and dairies. Wastewater from the chemical industry or mineral oil processing is also part of industrial wastewater. Independent of the specific industry sector, these different types of wastewater have one thing in common: the high energy content of the wastewater streams. Recovering thermal energy from process water The reuse of thermal energy already contained in the production cycle is becoming [...]

[...]Optimisation of existing treatment concepts through adapted machine technology Industries that produce wastewater with above-average pollution levels must either pre-treat it before discharge into the sewer or treat it completely biologically before it can be returned to water bodies. The relevant regulations result from the Water Resources Act, or from local statutes and environmental legislation. Since these industries can usually provide wastewater treatment with comparatively few resources, necessary optimisations are often not undertaken, and this is reflected in particular in increased [...]

[...]Bitburg and Kyllburg, Germany A HUBER Service partnership on the basis of our service and maintenance contracts has meanwhile become a much-demanded HUBER Service product worldwide, especially when it comes to absolute security for plant operation yet low and calculable operating costs! Preventive maintenance and inspection on a manufacturer quality level and their benefits for the customer, such as high operational reliability high machine performance calculable operating costs maintenance of value and investment security professional and reliable support of the operating staff on site detailed[...]

[...]Rednitzhembach, Germany HUBER was awarded the contract in early 2024 to supply and install a HUBER Rotary Drum Fine Screen ROTAMAT® Ro2 with a downstream HUBER Wash Press WAP® for renewing the STW’s screening system. These have now been in operation since the end of August 2024. Technical challenge and solution in the screen channel A particular challenge in this project was that the screen channel had to be widened from 600 mm to 1000 mm in the area of the screen basket. In order to minimise conversion time, which included demolishing the old channel and continuing to operate the sewage treatment[...]

[...]Reduce Volume of Industrial Sludge Through Thickening, Dewatering or Drying In the wastewater treatment process, substances are removed from the wastewater and accumulate as screenings or sludge. In addition, biological processes, but also physical and chemical treatment processes such as the flotation process that is frequently used in industrial wastewater treatment, lead to the formation of sludge. Residues can also arise directly from industrial production in very liquid form. Process Technology HUBER solutions for reduction of disposal costs Depending on the upstream process step, the [...]

[...]Current situation In industrial production, products are typically manufactured from raw materials using water and external energy. In addition to residual and waste materials, used water and not inconsiderable amounts of surplus energy in the form of waste heat are usually generated. In addition to immediate reutilisation of the heat energy within the production process and/or direct discharge from the system via separate cooling systems such as cooling towers, larger amounts of heat are also discharged via the wastewater. Increasing demands on discharge quality requirements Particularly in[...]
