[...]Circular Grit Traps Separation of grit and other mineral materials transported with the wastewater with centrifugal force HUBER Circular Grit Trap HRSF Circular Grit Traps HUBER Vortex Grit Chamber VORMAX Circular Grit Traps Circular and vortex grit traps separate the grit from the wastewater with centrifugal force. Separation of the grit particles is supported by the rotational motion of the wastewater. Due to the radial rotation, the solids are very quickly collected within the centre of the grit chamber from where they can be separated and discharged.[...]

[...]Targeted dosing of chemicals for better clarification performance with less consumption The use of chemicals such as acids, alkalis, flocculants or flocculation aids is necessary in many areas of wastewater treatment and sludge treatment in order to achieve the required process performance. Ideally, the right chemicals should be added in exactly the right dosage to avoid either underdosing or overdosing. While underdosing leads to reduced performance, overdosing leads to increased operating costs and can also have a negative impact on the process. The fluctuations in concentration and volume[...]

[...]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[...]

[...]Catch basin, rectangular in shape, made of 1.4307 (AISI 304 L) stainless steel. Universally applicable, for retrofitting under manhole covers as protection against ingress of harmful chemicals, liquid or similar substances into the manhole. Custom-made to suit the specific local conditions. The cover is made of stainless steel plate, with a centrally raised profile, removable, with two handles. The frame consists of an angle section designed as an outlet channel, provided for bolted fixing inside the manhole under the manhole cover, with integrated ¾“ hose nozzle, for on-site connection to an [...]

[...]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. [...]

[...]Development of innovative sewage treatment technology as a component for energy self-sufficient treatment plants For the process changeover from aerobic to anaerobic sludge stabilisation fine screening systems represent a highly interesting alternative when it comes to reducing the solids loads in the biological treatment stage. Fine screening achieves better removal rates than a conventional primary settling tank but on a much smaller footprint and with significantly lower investment costs. Changeover from aerobic to anaerobic sludge stabilisation reduces aeration costs by at least 20-25%. The [...]

[...]Efficient wastewater pre-treatment to achieve indirect discharge quality Compared to municipal wastewater, the generated industrial wastewater is much more polluted, and the composition of the wastewater varies greatly. In particular, pollution by organic or inorganic substances depends on the sector of industry, the product range, the production methods and, last but not least, the individual usage behaviour. Many industries discharge their wastewater directly into the sewer and must therefore comply with certain limits for COD and solids, ensure pH neutrality and reduce grease content to a minimum[...]

[...]Our demonstration plants with the HUBER Drum Screen LIQUID for the reduction of the pollution load in the inlet to wastewater treatment plants are in great demand and fully booked until 2020. Even in the local press, our machine technology receives attention again and again. On average, the location of a trial plant changes every 8 weeks. To ensure that everything runs smoothly, a well-coordinated, proven HUBER team takes over the organisation and integrates the responsible persons on site. Two applications are in special demand by our customers: Bridging operation during the rehabilitation of[...]

[...]Stay on the safe side! The need for security has strongly increased especially in the recent past. This development can be recognized in nearly all situations of life. The security requirements are however especially high where a great many people could be affected very easily. Drinking water supply is an example for such a case. The facilities in this sensitive environment are often in a very poor condition. To identify potential weak points, the authorities recently simulated burglary attempts on public institutions, among them also drinking water supply structures. This campaign lead to [...]

[...]All-round building protection with tested security We must eliminate the risk of any manipulation of our drinking water and its quality. Access to the free water surface must be prevented and the plants protected against vandalism and theft. The exterior shell of objects should therefore be designed as a mechanical barrier with a long resistance time. Criminal investigation departments recommend, among other measures, the use of security doors certified to resistance class RC3 or RC4 in compliance with DIN EN 1627. For vertical access, it is best to use tested security manholes covers . Certified[...]
