[...]Schallstadt, Germany The energy turnaround has already been under discussion for several years. The events on the energy market in 2022 at the latest have now made it very clear to the public that there is a very great need for reorientation on the “heat market”. The discussions about the right fuel are in full swing. HUBER SE has a solution that does not require any fuel at all: it is based on exploiting the energetic potential of wastewater using the HUBER ThermWin system. Energy from wastewater replaces renewable and fossil fuels In Schallstadt in Baden-Württemberg (Breisgau-Hochschwarzwald[...]

[...]By generating electricity and heat from digester gas, operators of wastewater treatment plants with anaerobic sludge stabilisation can generate energy themselves, and thus significantly reduce the purchase of external energy and consistently and sustainably lower their operating costs. Under suitable conditions, by feeding external and organic-rich waste (co-substrates) into the digester, gas and thus energy production can even be increased to the point of energy self-sufficiency. Typically, liquid waste from the food industry or catering (such as grease separator contents or flotate sludge[...]

[...]Newark, UK A HUBER Technology Wastewater Case Study HUBER Technology recently completed a project at Crankley Point STW located in Newark. The scheme was part of a £60 million investment by Severn Trent Water in Newarks waste and water systems to prevent flooding at around 400 homes in Newark. Part of this work involved the construction combined sewer tunnel 2.8m in diameter with a new terminal pumping station built at Crankley Point STW. Project Profile HUBER Technology were first approached to look at the outline design of the project in 2012 directly by Severn Trent Water and as the project [...]

[...]Davidstowe, UK Following successful trials using the HUBER Technology pilot plant Screw Press Q-PRESS®, Dairy Crest Creamery in Davidstowe went ahead and purchased 2 off HUBER Screw Press Q-PRESS® units complete with polymer dosing, pumps and controls. This has now been followed by a third order to cover for expansion of the effluent plant which has now been successfully installed and commissioned. Four different sludge streams arise from Dairy Crest’s modern effluent plant and it was initially thought they might behave differently with regards to polymer requirements and dewatering potential. [...]

[...]Cork, UK When DuPont needed to improve their on-site ETP performance, replacing the existing final settlement tanks with HUBER DAF units provided a compact solution. Background The site in Cork makes Micro Crystalline Cellulose Powder, a filler/binder for pharmaceutical and veterinary tablets. The raw material for this is Wood Paper Pulp. In the manufacturing process, large belt filters are used to recover the product as a wet cake but the filtrate and cake washings require treatment before discharge to sewer. The nature of the wastewater is similar to that found in a paper mill, rather than a [...]

[...]Dublin, Ireland A new Anaerobic Digestion plant outside Dublin has been provided with high efficiency HUBER grit removal and grit washing, to ensure trouble free operation and reduced downtime. Background Material accepted at site includes kerbside food waste collection as well as other organic material. This material is de-packaged and screened, but the resulting pulp still contains large amounts of grit (stones, glass, eggshells and bones). If not removed, this grit blocks and abrades both pumps and tanks. In particular the digester itself can accumulate grit, reducing the effective volume and [...]

[...]Cannock STW, UK HUBER Technology recently completed a project for Severn Trent Water at Cannock STW, north of Birmingham. HUBER Technology were engaged on the project in 2018 with the project being installed in late 2019 and commissioned in 2020. Project Profile This project was part of the upgrade to the Four Ashes and Cannock STW sludge treatment capability to include finer screens and provide sludge thickening. HUBER Technology Supplied 2 x HUBER Sludgecleaner STRAINPRESS® 290 5mm Sludge screens including Control Panels to Severn Trent Water Specification and a 6m high gantry to mount the[...]

[...]Charfield, UK As part of the Wessex Water inlet screen replacement projects, HUBER Technology completed the delivery and installation of a new inlet screen and screenings handling project at Charfield STW near Wooton under Edge. Project Profile Installed on site was an old 20mm bar screen discharging into a launder feeding a macerator and licep unit. All the equipment installed were at the end of their asset life and were constantly failing. The inlet screen was also allowing rag to bypass it due to its age. HUBER Technology Supplied HUBER Micro Strainer ROTAMAT® Ro9/700/6 without washwater or[...]

[...]Dublin, Ireland HUBER Technology UK was chosen as supplier of seven bar screens and seven screenings wash-presses for the Dublin Bay Inlet Works at Ringsend. The order also included supply of all control panels for all our machines. The plant’s management selected our multi-rake bar screens RakeMax® because of their low head loss during peak flow, in spite of their small bar spacing. Another selection criterion was their great screenings removal capacity. It also helped that our super-launder screenings presses WAP® SL provide superior washing intensity and compaction capability, resulting in a [...]

[...]Penrith, UK Originally, the two existing perforated plate (escalator-type) screens at the Penrith wastewater treatment plant discharged their screenings into a launder trough wherefrom they were flushed to a tank incorporating macerator pumps. These pumps grinded the solids and returned them back to the works. Besides the fact that the entire system did only comminute the screenings, but did not remove any solids, the system did not operate reliably. The main problems encountered by the operators were that the macerator pumps required constant maintenance and that, under certain circumstances, the [...]
