[...]Efficient and reliable removal of coarse material from sludge For the operational safety of sludge treatment processes, it is advantageous if the sludge is as free as possible of coarse material and disturbing solids (e.g. paper, plastics, fibers, and hair). Otherwise, repeated malfunctions of aggregates and processes may occur in pumps, but also during thickening, dewatering, or drying, these can be time-consuming, costly to rectify, and require increased manpower. For the agricultural recycling practiced in many regions of the world, it also makes sense to separate all solids, such as plastic[...]

[...]Solutions for cost-efficient sludge dewatering Sewage sludge produced in municipal and industrial wastewater treatment plants requires dewatering prior to further treatment or utilization. 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 is a good idea 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. It is viscous but still pumpable. Sludge Volume Reduction Excess Sludge Thickening Sludge settles in gravity thickeners and is compressed by[...]

[...]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[...]

[...]From the screen to the screenings wash press – reliable and operationally safe solutions for conveying screenings HUBER offers two different solutions for providing tailor-made and project-specific conveying systems for wet and untreated screenings: Screenings transport by launder channel The screenings to be treated are discharged from one or more screens into the launder channel. Sufficient wastewater or process water is used to flush the screenings into the screenings wash press. The flushing water also serves as wash water for screenings washing. HUBER Launder Channels HLC can be [...]

[...]HUBER solutions for permanent safe drinking water supply and distribution In water networks, many manholes are installed to accommodate branches, shut-off valves, backflow preventers, and sampling points. The manholes must be securely covered, sealed, and well ventilated. In addition, they must be safely accessible via step irons or ladders. HUBER supplies permanently safe stainless steel components for manhole equipment: Manhole covers Venting chimneys Safety access ladders and safety climbing systems with guard rail Entrance aids Pre-fabricated stainless steel manholes HUBER stainless steel [...]

[...]Complete system solutions for drinking water reservoir equipment HUBER has been committed to the development and supply of equipment for drinking water reservoirs for decades and relies on stainless steel material. A wide range of standardized products as well as complete system solutions have been developed. The product range includes manhole covers , venting chimneys , access ladders , doors , louvres , windows , and pressure-tight doors . Many standardized parts are even available from stock at short notice. In addition, HUBER develops taylor-made solutions together with the customer. Reliable[...]

[...]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 customized 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 [...]

[...]Complete process technology for the treatment of surface water Surface water can be treated into drinking water using the following physical, mechanical, and chemical process steps: Coagulation: Dosing a coagulant to the raw wastewater Flocculation: Dosing a flocculant and possibly a flocculation aid to the raw wastewater results in the formation of flocs. Clarification: The flocs are separated from the water, for example with a lamella separator. Filtration: The clarified water is then filtered in order to separate even the smallest solids and flocs. Depending on the requirements, single-layer [...]

[...]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 onsite plant for the complete treatment of septic sludge can also be built. Septic[...]
