[...]Sustainable Use of our Waters Municipal wastewater contains between 5 and 15 mg/l phosphorus. If phosphorus is not adequately removed during wastewater treatment, it ends up in the “receiving waters”. In lakes and rivers, phosphorus acts as a nutrient that generally promotes and accelerates plant growth, especially algae growth, which has a negative impact on water quality and thus on the biotic communities in the water body. Reducing phosphorus inputs from municipal wastewater treatment plants is therefore a very important contribution to maintaining or achieving a good ecological status in [...]

[...]Highest purification quality and reuse of wastewater The membrane bioreactor process is a biological wastewater treatment process that works according to the principle of the activated sludge process (aerobic biological treatment of organically polluted wastewater with activated sludge), except that the secondary sedimentation tank, which ensures biomass retention, is replaced by membrane filtration. Membrane Technology Membrane Bioreactor Process The use of membrane technology greatly reduces the space required, as the structures necessary for the treatment process at municipal and industrial [...]

[...]Denitrification in the sand filter for nitrogen reduction Nitrogen is a basic building block of life and nature and, like phosphorus, is indispensable as a nutrient for all humans, animals and plants. Municipal wastewater contains various nitrogen compounds (including organically bound ammonium and nitrate). The removal of nitrogen is one of the main tasks of municipal biological wastewater treatment, because without sufficient nitrogen removal, the discharge of wastewater into receiving waters has significant negative effects on water quality and thus on flora and fauna. Denitrification Downstream[...]

[...]Efficient wastewater pre-treatment to achieve indirect discharge quality Compared to municipal wastewater, the generated industrial wastewater is much more polluted, and the composition of the wastewater varies greatly. In particular, pollution by organic or inorganic substances depends on the sector of industry, the product range, the production methods and, last but not least, the individual usage behavior. Many industries discharge their wastewater directly into the sewer and must therefore comply with certain limits for COD and solids, ensure pH neutrality and reduce grease content to a minimum[...]

[...]Optimization 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 optimizations are often not undertaken, and this is reflected in particular in increased [...]

[...]Treatment of polluted stormwater to protect water and soil Road wastewater treatment plants are used for heavily frequented roads. The task of such a plant is to filter rainwater that runs off roads before it is discharged into a body of water or into the ground. Road run-off is stormwater contains coarser solids such as gravel, sand and litter, as well as significant amounts of finer solids such as abrasion from car tires (microplastics). Road wastewater occurs whenever it rains, and its quantity depends on the amount of rainfall. Technology for Road Wastewater Treatment Plants Intermediate [...]

[...]Increasing operational safety for pumping stations Pumps and lifting units are used where wastewater needs to be lifted to a higher level so it can be passed further on by gravity. However, the solids contained in the wastewater (coarse materials, foreign matter, fibers) often lead to a failure of the units used, as they cause operational downtimes due to clogging and blockages. Labor-intensive manual cleaning is required to restore the function of the units or, in the worst case, they even need to be replaced. To ensure trouble-free and reliable operation of a pumping or lift station, the [...]

[...]Screens for solids retention at sewer overflow structures for the protection of water bodies Structures with overflow are used to relieve the sewer system during rainfall. They either discharge the excess water/sewage/combined water directly into the receiving watercourse or initially store it temporarily. In practice, different types of structures can be found: Stormwater overflow: As soon as the water level in the sewer rises above a maximum permissible level, wastewater is discharged into the receiving water via an overflow channel. Stormwater overflow tank: When the rain weather begins,[...]

[...]All-round building protection with tested security We must eliminate the risk of any manipulation of our drinking water and its quality. Access to the free water surface must be prevented and the plants protected against vandalism and theft. The exterior shell of objects should therefore be designed as a mechanical barrier with a long resistance time. Criminal investigation departments recommend, among other measures, the use of security doors certified to resistance class RC3 or RC4 in compliance with DIN EN 1627. For vertical access, it is best to use tested security manholes covers . Certified[...]

[...]Sustainable processing and recycling of mineral waste Mineral-rich wastes such as street sweepings, sludge from sewer flushing and cleaning of stormwater tanks and gullies, and grit trap material contain not only grit and gravel but also trash (e.g. packaging material), coarse materials (e.g. stones, wood, glass, metal parts), and organic materials (e.g. soil, leaves, grass, fruit stones and cereal grains). For the processing and treatment of such mineral wastes HUBER offers individually designed grit treatment processes. Process Process technology according to requirements Depending on the required[...]
