[...]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 [...]

[...]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 [...]

[...]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 [...]

[...]Suitable materials and effective corrosion protection for economical solutions The right choice of material for screens and screening machines is a key factor for their reliable and low-maintenance operation. For applications with river water and fresh water, we use 304 and 316L stainless steel. For applications in particularly corrosive seawater with high temperature and salinity, we use stainless steel in combination with corrosion protection as well as corrosion-resistant duplex stainless steel and super duplex stainless steel. All steel parts are pickled and passivated in our own production[...]

[...]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 the material stainless steel.

[...]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 and 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 [...]

[...]The first step of operationally reliable and efficient wastewater treatment The separation of solids in wastewater with screens and fine screening systems is the first step in municipal and industrial wastewater treatment. The main task here is to remove all coarse and foreign materials that could inhibit or hinder the function of subsequent wastewater treatment stages. The following factors, among others, must be taken into account when planning an operationally reliable solids separation solution: Maximum required hydraulic throughput Expected screenings quantities Required bar spacing or [...]

[...]Increasing operational safety for pumping stations Pumps and lifting units are used where wastewater needs to be lifted to a higher level so that it can be passed further on by gravity. However, the solids contained in the wastewater (coarse materials, foreign matter, fibres) often lead to a failure of the units used, as they cause operational downtimes due to clogging and blockages. Labour-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 [...]

[...]Reducing screenings volume and disposal costs The screenings from municipal wastewater treatment mainly consist of household waste-like materials, faeces, paper and mineral particles. The screenings volume depends on the aperture size of the screening system. The solids content of municipal, untreated screenings varies from 5 – 20 %, depending on the type of screen. The organics contained in the screenings amount on average to approx. 90 % of the dry residue [DR]. The objectives of screenings treatment are: Dewatering of the screenings and thus reduction of screenings weight and volume. This [...]

[...]Reliable compliance with effluent values In conventional municipal wastewater treatment plants, the final settling tank is the last stage of the wastewater treatment process. The purpose of the secondary clarifier is to allow the activated sludge flocs and the finest suspended solids to settle and to discharge the clarified wastewater into the receiving water as free of solids as possible. Increasing hydraulic loads and changes in the settling behaviour of the activated sludge are the reason why wastewater treatment plants often do not reliably meet today's minimum requirements for solids retention[...]
