[...]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 processing capacity, the composition of the input material to be treated as well as the requirements on the output material and other general conditions, different process engineering concepts are necessary. The main process stages of grit treatment are: HUBER Grit Acceptance System RoSF7 Receiving and intermediate storage tank for the material delivered and to be processed (e.g. sewer grit, road sweepings). HUBER Wash Drum RoSF9 The wash drum is used to separate all coarse material and foreign matter that would make further treatment difficult. HUBER Coanda Grit Washer RoSF4 The grit washer separates organic matter from the mineral fraction and produces clean grit with an organic content < 3%. Wash water treatment If the wash water required for grit processing is not provided externally, the grit processing plant can also be supplemented with a wash water treatment system. The required water is then purified and can be reused (water cycle). On the basis of its wealth of experience in developing complete grit treatment systems, HUBER is able to provide a tailored concept for each individual grit treatment project.[...]

[...]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 operation of a sludge dewatering system, sludge conditioning plays a very important role in addition to selecting the right dewatering unit. Not only is it important to select the right flocculant and to ensure optimum dosing (concentration, quantity, dosing point), but also to mix the flocculant properly into the sludge to achieve good floc formation, which then leads to an optimum dewatering result. HUBER offers various machines for sludge dewatering and, based on decades of experience and thousands of installations, can always design the best suitable solution for different throughputs and different sludge qualities. The overall solution of a modern sludge dewatering system also includes the transport of the dewatered sludge to further sludge treatment or to intermediate storage (container or bunker). Here, too, HUBER has extensive expertise and can provide tailor-made solutions for the transport of sludge .[...]

[...]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 compressed by the weight of its own solids. Primary sludge from the primary clarifier of wastewater treatment plants and digested sludge from anaerobic sludge treatment thicken better statically than secondary sludge because of the higher density of their solids. Secondary sludge (excess sludge) from the secondary clarifier is preferably thickened mechanically separate from the primary sludge. Polymers are mixed into the thin sludge for flocculation before the sludge is added to the thickening machine. The sludge water released by flocculation drains by gravity through a filter medium (cloth or fine screen) while flocs are retained thereon. Mechanical excess sludge thickening is a prerequisite for the economic operation of anaerobic sludge stabilisation in a digester. HUBER offers various machines for sludge thickening differing in design, size and throughput capacity. We offer best-performing equipment for every application.[...]

[...]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. Septic Sludge Treatment of septic sludge Septic sludge is usually delivered by tankers and must be screened of coarse material and contaminants such as sanitary products and plastic particles etc. before further treatment. This cleaning is necessary for the reliable and economical operation of subsequent stages of septic sludge treatment or co-treatment of the sludge in sewage treatment plants. Depending on the size of the treatment plant, it is advisable to first store the septic sludge in buffer tanks after mechanical pre-treatment, from which it can then be continuously transferred to further treatment. For the acceptance of septic sludge, HUBER has developed special septage receiving stations , which have been successfully used worldwide for decades. With the use of this technology, it is then possible for the septic tankers to empty quickly and for the removal of all coarse material and contaminants to take place reliably and without disturbances. For septic sludge treatment plants our HUBER Screw Presses Q-PRESS® and S-PRESS are also used.[...]

[...]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, fibres and hair). Otherwise, repeated malfunctions of aggregates and processes may occur in pumps, but also during thickening, dewatering or drying, and these can be time-consuming and costly to rectify and require increased manpower. For the agricultural recycling practised in many regions of the world, it also makes sense to separate all solids such as plastic parts for reasons of environmental protection and aesthetics. Depending on the application, HUBER has different machines for sludge screening in its product range so that the right machine and technology is available for every application, every installation situation and any throughput rate.[...]

[...]HUBER masters growing challenges in wastewater treatment with digital solutions: HUBER Cloud Solutions HCS Counteracting rising operating costs and quality requirements through digital solutions Identify and exploit optimization potentials through data evaluation HUBER Cloud Solutions HCS as a basis for future additional services The challenges in wastewater treatment are constantly growing and the adequate treatment of wastewater and sludge at wastewater treatment plants is becoming increasingly difficult. The reasons for this are the increasing demands on the treated wastewater and sludge combined with dwindling personnel resources and rising costs for energy and operating materials. As a result, the treatment of wastewater and sludge must be optimized in an efficient manner. Potentials of Digitalization Challenges: Counteracting rising operating costs and quality requirements with the potentials of digitalization In order to successfully meet these challenges and support wastewater treatment plants in their operation, HUBER is developing new solutions and services. In doing so, the company is increasingly focusing on the benefits of digitalization and digital transformation and is further developing its products and solutions by consistently incorporating digital potential into the product development process. Objectives: Status description and optimization potential through data analysis The "raw material" of digital transformation is primarily data. This data is generated at any time by sensors and actuators in a machine or process. The collection and subsequent evaluation of this data requires specific knowledge of the machine and process technology as well as knowledge of mathematics and statistics. The evaluation makes it possible to describe the condition of a machine or process and to identify optimization potentials. These may include recommendations for lower-wear operation, advice on reducing electricity and water consumption, and suggestions for reducing operating materials such as precipitants and flocculants. Implementation: Development of the HUBER Cloud Solutions HCS To implement these goals, HUBER has started the development of the HUBER Cloud Solutions HCS, in which the digital service offers will be bundled in the future. The basis of this service is the recording of data at the local switchgear and control system of the machine or process and the transmission of the data in encrypted form via the internet to the HUBER Cloud for further processing. On the one hand, this includes the real-time calculation of key figures, which can be used to interpret the status of the machine or process. In the event of both atypical, abrupt changes and creeping, gradual deterioration in the key figures, the operator can be given immediate recommendations for action to maintain and improve the process. On the other hand, the data is used for further analysis to create additional key figures and gain new insights. In this way, customers continuously benefit from HUBER’s constantly growing knowledge and reduce both their time for troubleshooting and process optimization and their effort for machine maintenance. All recorded data as well as the calculated key figures are visualized in the HUBER Portal and are thus also available online to the operator at any time.[...]

[...]Protecting technical facilities against flooding Both our rivers and watercourses and the technical drainage systems (sewers) can only absorb limited amounts of precipitation. Depending on the degree of sealing and other local conditions, flooding can then occur above a certain precipitation intensity. As climate change is causing more heavy rainfall, the probability of flooding is likely to increase in the future. A variety of flood prevention measures The best protection against flooding is to prevent situations of extreme flooding from occurring in the first place. Any measures that allow sufficient space for the water are of helpful here, since rivers need adequate floodplains and must not be technically constricted and straightened. Decentralised infiltration and deconstruction of sealed surfaces also help to reduce rainwater run-off into the sewage system. Technical flood protection Despite many efforts, it will not be possible to completely eliminate the risk of flooding in many regions. In these cases, however, it must be guaranteed that no people are endangered in the event of flooding and that damage to technical facilities is minimised. In addition, it must be ensured that important facilities such as of water supply and wastewater disposal can be maintained for as long as possible. For protection against flooding and backwater, we offer our flood-proof HUBER Manhole Covers as well as flood-proof technical doors for use in wastewater treatment plants, sewers, water supply systems, elevated reservoirs, manholes and buildings.[...]

[...]Reliable conveying technology for grit and mineral solids Grit is separated by sedimentation in grit chambers during wastewater treatment. The grit settling at the bottom of the grit chamber is then removed – usually discontinuously – from the grit chamber. Grit Feeding and Conveying HUBER offers different designs of grit traps for grit separation. All HUBER grit traps are equipped with an appropriate conveyor so that the separated grit can be discharged into a container or passed to further treatment in a grit washing plant . Depending on the grit chamber design, either grit discharge pumps or screw conveyors are used for grit removal. HUBER can also supply tailor-made screw conveyors for operationally reliable grit transport in concrete grit chambers. Feeding of grit processing plants For feeding the material to HUBER grit treatment plants, HUBER offers storage tanks with discharge screws. The mineral material to be processed is temporarily stored in the tank and fed to the grit processing plant by a screw conveyor. The HUBER storage tanks can be installed above or below ground and can optionally be equipped with a debris separator and/or dewatering unit.[...]
