[...]Production increase or conversion of production make it necessary to upgrade the wastewater treatment systems For reasons of cost and efficiency, industrial wastewater treatment plants are often planned and constructed according to the current capacity utilisation of the facilities. Changes in production and product changes, capacity increases and other factors often lead to plants being too small at the time of commissioning or after a few years already, and the required effluent qualities can no longer be achieved. While machine technology that is too small can often be easily adapted to the [...]

[...]Process engineering solutions for the treatment of drinking water For the production of drinking water (especially when surface water is used), physical process steps are often necessary to remove solids of different types and sizes. HUBER has customised mechanical and process engineering solutions for the various applications: Specially developed screens for water abstraction remove all inadmissible coarse and solid matter from the raw water from rivers and seas. If required, suitable devices for fish protection can also be provided. Particularly in the case of machine technology for seawater [...]

[...]Minimise wear and increase operating reliability For the operating safety and reliability of wastewater treatment plants, it is necessary to separate the grit transported with the wastewater and other mineral materials from the putrescible organic matter. For this purpose, grit chambers of various designs are used in practice. Depending on the type of grit trap, grease can also be separated in addition to grit. The removal of grit from the wastewater serves to prevent operational troubles, such as grit sedimentation (in aeration tanks and digesters), increased wear (of pumps, stirrers) and [...]

[...]Elimination and reduction of micropollutants with the PAC process Trace substances can be removed from wastewater with the help of powdered activated carbon (PAC), as the micropollutants adsorb to the activated carbon. Powdered activated carbon is ground activated carbon. According to DIN 12903, at least 95 percent of the mass fraction must have a grain size of less than 150 µm. The average particle diameter of typical powdered activated carbons is approximately in the range of 10 µm to 50 µm. For the elimination of micropollutants, the powdered activated carbon is added directly to the wastewater[...]

[...]Grit washing for Reduction of the Organic Matter Contained in Grit Grit and mineral substances from the grit chambers of municipal wastewater treatment plants usually contain a large to very large proportion of organic substances, which have settled in the grit chamber together with the grit. Grit washing has become an established process for the treatment of grit from grit chambers over the last decades. HUBER Grit Washing Plants have been in operation worldwide for more than 25 years and have set the standard for modern and efficient processing of grit from wastewater treatment plants to [...]

[...]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[...]

[...]Solutions for cost-efficient sludge dewatering Sewage sludge produced in municipal and industrial wastewater treatment plants requires dewatering prior to further treatment or utilisation. Rising costs for sludge disposal make it necessary to concentrate the sludge to a high solids content. Mechanical sludge dewatering is used to reduce the amount of sludge by separating sludge water. A more or less firm sludge cake is produced. Prior to its dewatering, fed sludge is first flocculated by addition of polymers (sludge conditioning). Sludge Conditioning Economic Sludge Dewatering For the economic [...]

[...]Mechanical sludge thickening to reduce sludge volume Before sludge with a very high water content is subjected to further treatment, it makes sense and is often necessary to reduce its volume by thickening. This also increases the solids content of the sludge. If sludge with a solids content of 1% is thickened to 6% solids, this gives a volume reduction of more than 80%. The thickening of the sludge is effected by separating sludge water; thin sludge becomes thick sludge, which is viscous but still pumpable. Sludge Volume Reduction Excess Sludge Thickening Sludge settles in gravity thickeners and is[...]

[...]Reliable pre-treatment for septic sludge Wherever wastewater is not fed to a sewage treatment plant via the sewer system, but is treated decentrally, septic sludge is produced. This septic sludge collects either in simple septic tanks or in more modern small wastewater treatment plants and must be removed at regular intervals to be treated in a central plant. Where possible, this is done at a centralized wastewater treatment plant with sufficient surplus capacity; but where such a plant is not available nearby, a separate on-site plant for the complete treatment of septic sludge can also be built.
