[...]Birmingham, England A HUBER Technology Industrial Wastewater Case Study HUBER Technology recently completed a project for the largest confectionery manufacturer in the UK at their site at Marlbrook between Leominster and Hereford. The project for Mondelez which own confectionery brand Cadbury was delivered following good early engagement to allow a successful project to be delivered. Project Profile This project was part of the upgrade to the sites effluent treatment plant to include for a provision of sludge dewatering capability on site. It involved removal of an existing redundant DAF [...]

[...]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[...]

[...]Various solutions for conveying dewatered and dried sewage sludge Sludge transport plays an important role in the planning and construction of sludge drying plants. On the one hand, the dewatered sewage sludge has to be brought into the dryer and on the other hand, the fully or partially dried sewage sludge has to be transported away from the dryer. When designing a particular transport solution, important criteria include not only the required transport capacity but also the sludge properties (moist, dry, sticky, dusty,...) and the desired degree of automation. Feeding and Removing Supply and[...]

[...]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 [...]

[...]Sludge Drying Cost reduction on sludge transportation and disposal costs. Efficient solutions to minimise the volume of sludge for disposal Wastewater sludge is dried to minimise its mass and to save sludge transport and disposal costs. Handling and storage of dried sludge is cost effective, and any further disposal and utilisation methods are possible. The dried product can be used as fertiliser, as well as fuel – the calorific value of fully dried sludge is similar to that of brown coal. Thermal energy from different energy sources Thermal drying involves the evaporation or vaporisation of [...]

[...]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 [...]
