[...]Elimination of Trace Substances Solutions for the elimination of trace substances and micro pollutants from wastewater Adsorption process with powdered activated carbon (PAC) Elimination and reduction of micropollutants from wastewater: Adsorptively removal of trace substances with powdered activated carbon, which is added to the wastewater and then separated again by means of a polishing filter (before the treated wastewater is added to the receiving water.) Adsorption process with granulated activated carbon (GAC) Elimination and reduction of micropollutants from wastewater: The removal of trace substances is carried out adsorptively with granulated activated carbon, whereby ozone can be additionally used. It has been proven that wastewater treatment plant effluents are significant input pathways for anthropogenic trace substances (especially pharmaceutical residues) into our water bodies. In the aquatic environment, these micropollutants have negative impacts and in conventional wastewater treatment plants, these substances are only insufficiently degraded. In order to achieve a more extensive elimination of micropollutants in municipal wastewater treatment, special processes of advanced wastewater treatment are necessary. Elimination of micropollutants is also referred to as the fourth purification stage or quaternary treatment. There are different processes for the elimination of micropollutants, for each of which HUBER has different machinery and plant technology in its product range. Adsorption process with powdered activated carbon : In the process with powdered activated carbon (PAC), the trace substances are adsorbed on powdered activated carbon. Adsorption process with granulated activated carbon : In the process with granulated activated carbon, the GAC process, the micropollutants are adsorbed on granulated activated carbon. Note: When considering the elimination of micropollutants, it is highly recommended to keep the synergy effects of solids reduction and phosphorus elimination in mind, as these can skilfully be exploited, taking into account all individual boundary conditions. FAQ Frequently Askes Questions What are anthropogenic micropollutants? Anthropogenic micropollutants are man-made chemicals that enter water bodies via wastewater and have negative effects even in low concentrations. Typical trace substances of this kind are, for example, medicines, cosmetics, cleaning agents or plasticisers in plastics. Industrial chemicals, corrosion protection agents, pesticides and biocides also belong to this category of substances. Why should trace substances be removed from wastewater? Although trace substances are only present in wastewater in very low concentrations, they can still have an environmentally harmful effect. Not only active substances of the contraceptive pill but also many other substances such as bisphenol A can negatively influence the hormone balance of aquatic organisms. Other trace substances can damage the gills and internal organs of fish. In addition, trace substances can accumulate in aquatic animals and ultimately reach humans via the food chain. Why not prevent trace substances from entering wastewater in the first place? In principle, medicines and chemicals should not be disposed of down the toilet. But even if everyone followed this rule, these substances would still end up in the sewage system and thus in the wastewater treatment plants. All medicines that we take leave the body with our excretions and are therefore automatically in the sewage. Many objects that are exposed to rain, weathering or mechanical wear can release harmful substances, which are then flushed into the sewage system with the rainwater. Since the input of trace substances cannot be prevented in practice, the elimination of trace substances at the wastewater treatment plant is an effective way to remove the unwanted substances.[...]

Elimination of Trace Substances HUBER offers solutions for the elimination of trace substances and micropollutants from wastewater with granulated activated carbon (GAC) and powdered activated carbon (PAC). Membrane Activated Process The membrane activated sludge process is a biological wastewater treatment process that works according to the principle of the activated sludge process, but the secondary sedimentation tank for biomass retention is replaced by membrane filtration unit. The wastewater treatment process of a conventional municipal sewage treatment plant consists of a mechanical and a subsequent biological treatment stage. Increasing demands on the quality of the treated wastewater, however, increasingly require additional treatment stages, which are often referred to as third and fourth treatment stages, or collectively as “advanced wastewater treatment”. The aim of advanced wastewater treatment is the reduction of one or more of the following pollutants: solids, COD, BOD, phosphorus, nitrate, micropollutants and germs. HUBER is a competent partner for the implementation of different processes for advanced wastewater treatment: Solids reduction : reduction of suspended solids, COD and BOD before discharge of the wastewater into the receiving water or as a preliminary stage for further treatment Phosphorus elimination : reduction of phosphorus before discharge of treated wastewater into water bodies Micropollutant elimination : adsorptive and oxidative removal of micropollutants Biologically activated filtration : denitrification in sand filters Membrane activated sludge process : solids-free treated wastewater FAQ Frequently Asked Questions What is meant by tertiary treatment? In wastewater treatment, tertiary treatment means the third treatment stage and refers to processes of advanced wastewater treatment in which a further reduction of nutrients (nitrogen and/or phosphorus) takes place. The first two stages of wastewater treatment are mechanical treatment (primary treatment) and biological treatment (secondary treatment). What is meant by quaternary treatment? In wastewater treatment, quaternary treatment means the fourth treatment stage and refers to processes of advanced wastewater treatment in which micropollutants are eliminated. The first three stages of wastewater treatment are mechanical treatment (primary treatment), biological treatment (secondary treatment) and phosphorus and/or nitrogen elimination (tertiary treatment).[...]

[...]Solutions for Sludge Treatment Highly efficient and comprehensive solutions for all stages of sludge treatment Mechanical Sludge Treatment Solutions for reliable mechanical sludge treatment - screening, thickening, dewatering. Sludge Drying Wastewater sludge is dried to minimize its mass and to save sludge hauling and disposal costs. HUBER offers various solutions to minimize the sludge volume to be disposed. Efficient solutions for cost-effective sludge disposal and utilisation Sludge is produced during municipal and industrial wastewater treatment, and many industrial processes also generate sludge. This sludge can either be recycled or must be disposed of. The higher the requirements for wastewater treatment, the more sludge is produced. Primary treatment separates solids contained in the raw sewage – the primary sludge. Secondary sludge (excess sludge) is the separated biomass from the biological treatment stage. Tertiary sludge is generated by additional advanced chemical/physical treatment. The existing and future challenge in sludge treatment is to process the generated sludge with further process steps as cost-effectively and energy-efficiently as possible to such an extent that safe disposal or even economic use is possible. The objectives of sustainable environmental management have to be reconciled with economic aspects and practical solutions for the operator on site. HUBER has the right machines and plant technology for tailor-made solutions for all stages of sludge treatment: Mechanical sludge treatment : removal of coarse material and other solids, and thickening and dewatering of sludge to reduce volume. Sludge drying : thermal processes for partial or complete drying of sludge as a prerequisite for safe and economic sludge disposal or recovery.[...]

FAQs Frequently Asked Questions Where is a storm screen used? Storm screens are used in the combined storm and sanitary sewage line of a sewerage system at storm water overflows. These overflow structures serve to relieve the sewer network during rain events by temporarily storing wastewater or directly discharging it into the watercourse. How often does a relief discharge take place? Depending on the region and the type of structure, overflow discharge at a combined sewage screening system occurs several times a year. Usually, it is assumed that a storm screen is in operation for about 1000 hours in 10 years. What can be done to keep screenings from combined sewer overflows out of a water body? In a combined sewer system, direct overflow discharge to a water body can occur several times a year. Many municipalities therefore use a storm screen to prevent coarser solids from entering the watercourse in the event of overflow discharge.[...]

[...]Wash Presses Reliable screenings treatment with high dewatering efficiency and maximum washout degree for reduced disposal costs HUBER Screenings Wash Press WAP® Wash Presses HUBER Screenings Wash Press WAP® SL Wash Presses HUBER Screenings Wash Press WAP® SL HP Wash Presses Wash presses reduce the mass and volume of screenings and consequently the disposal costs The best method of screenings treatment is washing and compaction with a wash press. Fecal matter and other organic materials are removed and returned into the wastewater flow. As a result, a good wash press increases the BOD 5 load to the biological treatment process by about 6 %. After washing, the screenings are compacted to reduce the water content and increase the solids concentration. Dewatering is improved by the removal of organic materials during washing. A good wash press can achieve a weight and volume reduction of up to 80 % and thus consequently reducing the disposal costs.[...]

Our equipment, as proven during many years of experience, is especially suited for septic sludge treatment. Hundreds of HUBER plants for septic sludge treatment have been installed worldwide. Septic sludge is typically delivered in tanker vehicles. Depending on the size of the WWTP, it may be pumped into a balancing tank from where it is continuously fed to the plant. Direct feeding without prior balancing is possible at larger plants. In any case, removal of coarse material, such as hygienic products, plastic material, etc., from the septic sludge is necessary. There are several requirements for good septic sludge treatment: High capacity to minimise waiting time of tanker vehicles High separation efficiency to achieve excellent separation of non-degradable material Automation to minimise operator attendance Complete encasement to eliminate odour annoyance Reliable operation without impairment by grit and gravel Integrated screenings washing and compaction to produce screenings suitable for landfill and to reduce their weight and disposal costs To meet these requirements HUBER developed special machines and plants that have proven their efficiency and reliability in hundreds of installations. There are three options of septic sludge disposal on sewage treatment plants: Introduction into the wastewater flow Introduction into the sludge flow Introduction partly into the wastewater, partly into the sludge flow FAQs Frequently Asked Questions What are faecal sludge acceptance stations used for? Wherever residential buildings are not connected to a sewer system but use a decentralised domestic sewage treatment plant, faecal sludge accumulates. This faecal sludge is disposed of via collection vehicles and transported to a central sewage treatment plant or a special faecal sludge processing facility for treatment. The collection vehicles usually empty the faecal sludge into special receptions stations, also referred to as sludge acceptance plants. What is the advantage of using a sludge acceptance plant for faecal sludge? Using a sludge acceptance unit before the faecal sludge is fed into the wastewater treatment plant will clean the raw material from undesired matter, such as sanitary products and plastic articles, etc. This cleaning is necessary to keep the load on the sewage treatment plant resulting from the introduced faecal sludge as low as possible. What are components of faecal sludge? Faecal sludge is the sewage sludge from domestic sewage treatment plants. Faecal sludge usually consists of wastewater with a concentrated content of faeces, food waste, toilet paper, sanitary products as well as mineral components. For the treatment of faecal sludge, a multi-stage system consisting of coarse screen and grit trap can be useful before the faecal sludge is discharged into the sewage treatment plant.[...]
