[...]After intensive discussions with industry associations, partners and many exhibitors from all segments of IFAT, the fair was now canceled with a heavy heart, after it has already been postponed from May to September. The next IFAT will now take place from May 30 to June 3, 2022. The COVID-19 pandemic has a massive impact—also on the global environmental technology industry. In consultation with the Executive Board of the Exhibitors’ Advisory Board and the conceptual partners of IFAT, Messe München conducted a survey among the IFAT exhibitors, revealing that most respondents are against holding IFAT from September 7 to 11, 2020. Hence, IFAT at the planned time would be unacceptable—not only for Messe München but also for the trade fair participants. In addition, according to the latest announcements, major events must not be held until the end of August 2020. In order to provide all customers a reliable basis for planning and in close consultation with the Executive Board of the Exhibitors' Advisory Board, IFAT is canceled. “A safe and successful IFAT 2020 for all concerned—that was our primary concern. Due to the still unforeseeable circumstances, this objective is unfortunately no longer feasible, even for the new date,” explains Stefan Rummel, Managing Director of Messe München. The decision is based on intensive discussions with industry associations, partners and many exhibitors from all segments of IFAT. And a recent survey has confirmed this opinion. We will provide further information about our trade fair activities in due course. For further information please visit the IFAT webseite of Munich Tradefair . In the meantime, we are available for you as usual via all other sales channels and look forward to answering your questions by e-mail, telephone or via our website.[...]

[...]Wackersdorf and Föhren, Germany Sand and water, as the most important components for concrete production, are a basis of modern society. Due to the growing world population and the ongoing construction boom, both resources are becoming increasingly scarce. Smart solutions from HUBER are designed to remedy this by exploiting synergies of ecology and economy, thus promoting sustainable grit processing in the disposal industry. Intelligent and efficient products and solutions for grit processing not only in industrial plants include the HUBER Grit Treatment Process RoSF5, with the HUBER Horizontal Grit Dosing Screw RoSF7, the HUBER Wash Drum RoSF9 and the HUBER Coanda Grit Washer RoSF4. The HUBER Grit Treatment Process RoSF5 The HUBER Grit Treatment Process RoSF5 is the solution for processing grit, mineral waste and wastewater into reusable fractions. Especially the low operating costs and low maintenance requirements of the HUBER machine technology are decisive for the efficient treatment of the input material and thus also for waste management companies to plan economically. In addition, HUBER technology ensures a consistently high quality of the components to be recycled. This in turn provides the disposal company with planning security and can lead to competitive advantages. Used by waste management companies: intelligent HUBER solutions in practice Hammerer Kanalservice GmbH, based in Wackersdorf, Germany, and HP Enders Umweltservice GmbH, based in Föhren, Rhineland-Palatinate, Germany, have recognised the advantages of HUBER products and solutions: both waste management companies have met the steadily growing customer demands for a receiving station for grit from municipal wastewater treatment plants, industrial grit chambers and sewer flushing by taking a HUBER Grit Treatment Process RoSF5 into operation. Hammerer Kanalservice GmbH can accept up to 20 tonnes of raw material per day, process it and sell it profitably on the raw materials market. The processing plant of the waste management company HP Enders Umweltservice is designed for a solid material volume of 1 m³/h. Thanks to HUBER's treatment technology, HP Enders was able to immediately accept the sewer flushing material produced during last year's flood disaster and to make an essential contribution to the restoration of the sewer system. Acceptance of the liquid and solid phase in the receiving bunker of the HUBER Grit Dosing Screw RoSF7 The first step of the process is the discharge of the liquid phase from the tanker vehicles. For this purpose, the operator connects the vehicle via the hose directly to the provided Perrot connection. With the HUBER system, the liquid phase can be reused and recirculated as service water. Cost-intensive fresh water supply is therefore not necessary for the operation of the plant. This is a significant advantage because, compared to municipal wastewater treatment plants, the process water in industrial companies is not available in sufficient quantities and quality and not without additional costs. At the wastewater treatment company HP Enders, the solids are fed directly via the tanker truck into the receiving bunker of the HUBER Grit Dosing Screw RoSF7. Due to the situation on site at Hammerer, the grit as well as the mineral and organic waste is fed from the dewatering site to the HUBER reception bunker by wheel loader. In general, HUBER designs the receiving area according to customer specifications. Alternatively, a crane can be used to feed the waste into the HUBER reception bunker. Use of HUBER Grit Screw RoSF7 and HUBER Wash Drum RoSF9: separation and washing of coarse material The HUBER Grit Dosing Screw RoSF7 integrated in the receiving bunker feeds the material fully automatically into the HUBER Wash Drum RoSF9. In the wash drum, the fraction < 10 mm is washed out by homogenisation. Coarse material > 10 mm is separated by the inclined screening drum, statically dewatered and discharged into the customer’s bin. In addition, a magnet is provided for the separation of metals. Both operators dispose of the coarse materials, and the metals are sold after pre-sorting. Classification, washing and dewatering of the grit in the HUBER Coanda Grit Washing Plant RoSF4 In the next process step, the HUBER Coanda Grit Washing Plant is used. The grit, organic and water mixture (fraction < 10 mm) is fed into the plant via the Coanda tulip with upstream vortex chamber. The flow, which is set into strong rotation by the vortex chamber, is deflected from the vertical into the horizontal direction at the curved surface of the Coanda tulip due to the Coanda effect that occurs and is fed evenly into the container. The solids contained in the flow (grit particles, organic material) are then separated due to the flow diversion combined with flow velocity reduction, dependent upon the particle settling velocity, and sink down to the bottom area of the tank. There, the organic and mineral components are separated. Due to a defined introduction of upwardly directed service water the grit in the lower part of the HUBER Coanda Grit Washing Plant RoSF4 will be fluidised in the upflow, i.e. a locally defined grit fluidised bed is created. Within this fluidised bed the lighter organic particles are separated from the dense grit particles, independent of the particle size. The mineral fraction is then statically dewatered via the discharge screw and can be profitably sold by both companies to the construction industry. Organic and fine grit separation with the HUBER Compact Plant ROTAMAT® Ro5 The effluent from the HUBER Coanda Grit Washing Plant RoSF4 is then treated in the multifunctional HUBER Complete Plant ROTAMAT ® Ro5. Here, the organic and fine grit components are separated from the water stream in a grit channel in only one process step. Both the organic material and the fine grit < 0.2 mm are in turn dewatered and discharged by separate discharge screws. The fine grit is used, for example, in the recultivation or backfilling of pits in opencast mining and can thus be sold at a profit, while the organic components can be used in biogas plants. Sustainable internal water recycling for further reduction of operating costs: effluent from the HUBER Complete Plant ROTAMAT ® Ro5 supplying the Wash Drum RoSF9 The quality of the effluent from the HUBER Complete Plant ROTAMAT ® Ro5 is so good that it can be used directly as wash water supply for the HUBER Wash Drum RoSF9. The remaining wastewater is treated to clear water by the HUBER Dissolved Air Flotation Plant HDF at the end of the process. This clear water is reused as internal process water for the Grit Washer and the Complete Plant. In addition, Hammerer uses the clear water to refuel its suction vehicles. The disinfection plant ensures that the water is free of germs. The internal and external use of clear water reduces operating costs to a minimum, as the cost-intensive supply of fresh water can be dispensed with and, in addition, no wastewater subject to charges is produced. Furthermore, no additional compressed air is required for the saturation system of the HUBER Dissolved Air Flotation Plant HDF, which is another positive influence on the operating costs of the overall plant. Dissolved Air Flotation sludge is dewatered mechanically. The HUBER Grit Treatment Process RoSF5: smart, efficient, sustainable and economical The HP Enders and Hammerer project examples show that the turnkey HUBER Grit Treatment Process RoSF5 is the smart, efficient and sustainable solution for an adaptive system for grit treatment that guarantees a consistently high quality of the recyclable fractions and also saves operating costs. This technologically sophisticated process for grit treatment by HUBER makes an important contribution to the efficient use of resources – and has the nice side effect of being economical.[...]

[...]Changing from aerobic to anaerobic sludge stabilisation More and more municipalities in Germany are striving to optimise the energy efficiency of wastewater treatment on their sewage plants. Generally, there are two options: energetic rehabilitation or expansion of the treatment plant capacity. An expansion of the treatment plant capacity is possible through the construction of a new biological stage, but is counterproductive in terms of energy optimisation, since an additional biological treatment stage requires a considerable amount of additional aeration energy. This solution also increases disposal costs. The energetically more sensible option for the rehabilitation of small plants of 10,000-20,000 p.e. is very often to change from aerobic to anaerobic sludge stabilisation. This conversion makes it necessary to integrate both a mechanical pre-treatment unit and a digester for anaerobic sludge stabilisation into the system. Up to now, the literature has pointed out that the implementation of a digester would only be economically viable and make sense for expansion sizes larger than 20,000 PE. In view of rising energy costs and increasing disposal costs, this assessment has now changed fundamentally. An economic conversion from aerobic to anaerobic sludge stabilisation does not only require the economically best design of the digester, but also the optimal method of organic carbon removal from the biological treatment stage. Regarding the removal of organic carbon from the biological treatment stage, the HUBER Drum Screen LIQUID is the most economic option compared to a traditional primary clarifier (sedimentation tank), as numerous feasibility studies and implemented concepts have shown. The economic efficiency of a sludge digestion system depends mainly on the type of digester construction. In general, a distinction is made between concrete digesters, screwed steel silos with a bottom chamber, screwed steel silos with a concrete hopper and welded steel silos. However, it is not only the type of construction that influences economic efficiency, but also the type of sludge digestion process used. Compared to the usual fully mixed digester, in the "2-phase digestion" process the digester is operated with hydraulic displacement or stacking from the bottom to the top. This mode of operation means that there is no fresh substrate slip, and an increase in gas yield of up to 20% is achieved compared to conventional permanently mixed digesters. Another advantage of hydraulic displacement compared to a digester with mixing (agitator) is that a saving of 3-10 W/m³ can be achieved. Due to this process management without mixing, an enrichment and concentration of the necessary microorganisms is possible, which contributes to an increase in gas production. Economic process integration: Decisive for the economic efficiency of a possible process change from aerobic to anaerobic sludge stabilisation are both the electricity costs and the level of disposal costs. For wastewater treatment plants with an expansion stage of 15,000 to 25,000 p.e., there should be at least 200,000 euros per year in electricity and disposal costs. Furthermore, gas yield curves are used to draw conclusions about biogas production and sludge dewaterability. If a comparison of the original configuration of the wastewater treatment system with the system changed to anaerobic sludge stabilisation shows as a result a saving of at least 50,000 euros, a recommendation is made to continue the planning process.

(two gas turbines 65 kW / energy compensation 70 %) Project Pocking: (17,000 p.e.; one gas turbine 65 kW / 50% compensation) Advantages of 2-phase digestion: Retention time 10-14 days No circulation energy (savings potential: 3-10 W/m³) Increased gas production (up to 20% compared to mixed systems) Small installation space Low investment costs Fully welded stainless steel construction (preferred variant: welded steel silo) Figure 2 shows the individual variants of 2-phase digestion. The volume in each variant corresponds to 200 m³ with construction heights of 8 to 22 m. Due to the shorter service life of the screwed tanks, the "welded steel silo" design with bottom chamber is the most economical variant. The other variants shown are 5-10% higher in price. Subsidies for process conversion The selection of the digester system and the associated investment costs are an important criterion when applying for subsidies. With regard to compliance with effluent values, coordination with the lower water authority is necessary. No BiMSch procedure (procedure according to the Federal Immission Control Act) is required for the planning and implementation of the sludge digestion system. The funding according to the Local Authorities Guideline 2020 shows that 40% of the eligible costs are subsidised. CHP and machine installation rooms are not eligible. The prerequisite for applying for funding is the submission of a meaningful potential study. As this is ERDF funding, it can be combined with the Local Authorities Guideline.[...]

[...]Manholes fulfil an important task in water supply and wastewater disposal. They are used for example where shut-off fittings in pipelines must be accessible, or to control sections of very long pipelines, and for aeration/deaeration or access to complex installations (e.g. well shafts, pressure reduction shafts, and many other). Safe access must be ensured in each individual application. The operators of manhole structures are responsible themselves for the security of their manholes! Operating staff has to observe numerous instructions that should avoid accidents if applied correctly. Any work to be executed in manholes must be done by two persons. For security reasons, one person must stay outside the manhole. Most of the manholes are entered from the top. This means that operating staff must open a cover and climb into the manhole via a certified climbing system combined with a suitable, also certified entrance aid. They must bend over the manhole opening already when opening the cover. The installation of antifall guards can prevent accidents and provides a reliable protection against falling when opening manhole covers. The guards can be closed to secure the opening while working inside for a longer time. Nevertheless, the guards are designed to let in enough daylight. The antifall guards are dowelled into the manhole neck below the manhole cover and snap in automatically when opened. Due to their special design they provide sufficient stability to prevent that anyone can fall down. Such antifall guards can any time be retrofitted into existing manholes.[...]
