Bollfilter UK Limited

Bollfilter UK is a team of highly motivated, positive and professional people with extensive knowledge and experience of the filtration industry. Here are some recent testimonials.

As the dedicated technical sales arm of Boll & Kirch – Europe’s leading manufacturer of automatic water filters – Bollfilter UK provides complete filtration solutions and expertise through the supply of quality equipment, servicing, spares and support.

Boll automatic filters are widely used by the UK water treatment industry thanks to their reliability, performance and durability. Featuring unique backflushing technology, they are provide low maintenance filter protection for tertiary waste water systems and primary potable water treatment plant and are ideal for unmanned sites.

For potable water applications, Boll automatic filters can protect water treatment plant, such as membrane, UV disinfection, DAF recycling and ion exchange systems with a typical filtration level of 10-500 microns.

For waste water treatment, Boll automatic filters can screen final effluent down to 50 microns for intermediate wash water equipment, such as screens, belt thickeners, filter presses and centrifuges. They can also protect NSAF and sand filters and be used with disc filters to prevent spray nozzles from blocking.

For final effluent washwater booster pump protection, where overall pressure in the system is low but high pressure washwater is available, a Boll automatic filter fitted to the washwater feed will remove particulates to ensure efficient performance of pumps and keep downstream nozzles free from blocking.

Where automatic filtration is not required, i.e. on cleaner systems or for very coarse filtration, Boll & Kirch also offer a range of simplex and duplex manual strainers.

Bollfilter UK is dedicated to meeting and exceeding customer’s expectations from the first point of contact to the selection and supply of equipment, commissioning, after-sales support, spare parts advice recommendation and timely supply, on-site service/maintenance and training, and work for continual improvement through training and development.

Witches Oak WTW: Green Recovery - Decarbonising Water Resources (2024)

The challenges of designing and constructing the Witches Oak programme of works on multiple sites to a condensed timescale

Finham Advanced Anaerobic Digestion (2023)

Finham STW, situated near Coventry in the West Midlands, is Severn Trent’s fifth largest wastewater treatment works and treats over 115 megalitres of effluent a day from half a million people. The works processes indigenous sludge on site as well as accepting exports from local, satellite sites, producing final effluent, ‘cake’ and biogas as outputs. […]

Witches Oak WTW: Green Recovery - Decarbonising Water Resources (2023)

In the summer of 2020, the water industry was set a challenge by its regulators to identify ways to support the country’s green economic recovery from Covid-19. Severn Trent responded with a number of proposed programmes, including Decarbonising Water Resources (DWR), the subject of this paper. The objective of the DWR programme was to provide […]

Severn Trent Borehole Capital Maintenance (2022)

Severn Trent is undertaking a programme of rehabilitation works at one its borehole pumping stations (BPS); a groundwater abstraction site consisting of three boreholes (BH1, BH2 and BH3) that provides up to 10 megalitres per day (Ml/d). The three boreholes historically operated in a duty/assist/standby configuration. The site was previously operating at below its intended […]

Strongford STW - THP & LTP (2022)

Strongford STW is a major sewage treatment works serving the population equivalent of circa 350,000 from Newcastle-under-Lyme and Stoke-on-Trent. The site’s sludge treatment facility provides a major centre for regional operations. Based on a forecast increase in population, it was identified that an increase in treatment capacity would be required to accommodate the local growth. […]

Cog Moors Advanced Anaerobic Digestion Facility (2021)

Welsh Water’s sludge strategy is to treat 97% of sludge using advanced anaerobic digestion (AAD) technology. The Cog Moors AAD facility was constructed to supplement the existing facilities at Cardiff and Afan in South Wales along with the recently constructed Five Fords facility in North Wales. AAD gives the benefits of: Meeting the Enhanced Sludge […]

Poolend Borehole Capital Maintenance (2021)

Severn Trent’s existing Poolend Borehole Pumping Station is located near Leek in Staffordshire and is one of four sources that supply water to Ladderedge DSR. A second borehole source feeds into the Poolend site where both sources undergo water treatment (pH correction, plumbosolvency, marginal chlorination, and ultraviolet (UV)). To ensure continued water security in the […]

Durleigh WTC (2020)

Durleigh Water Treatment Centre is located approximately 2km west of Bridgwater, Somerset and is Wessex Water’s second largest surface water treatment works serving a population of 44,500. The site was originally designed to treat up to 28.5 Ml/d, with water drawn down from the 959,000m3 Durleigh Impounding Reservoir. Raw water quality has deteriorated in recent […]

Ketford Borehole Pumping Station (2020)

Severn Trent’s Ketford Borehole Pumping Station (BPS) is a critical source which feeds into the Bromsberrow BPS, where the water is blended before being pumped into supply. The pumping station was vulnerable to outage largely due to having a single operational borehole. There were three boreholes at the site (BH1, BH2 and BH3), which historically […]

Ardersier WwTW (2019)

Ardersier is located on the Moray Firth some 11 miles east of Inverness. The wastewater treatment works serves the town of Ardersier and the surrounding area including Inverness Airport and Fort George Barracks. It currently serves a population of less than 2,000 but there are significant developments planned in the area with a long-term future […]

Stocksbridge WwTW (2019)

Stocksbridge WwTW is located in the village of Deepcar on the outskirts of Stocksbridge, approximately 7km northwest of Sheffield city centre. It currently serves a population of 13,000, but this is expected to grow towards 15,000 by 2030. Major housing development is ongoing near the existing works, and as part of this Yorkshire Water reached […]

Audley Borehole Pumping Station (2018)

Audley Borehole Pumping Station is one of Severn Trent Water’s (STW) borehole capital maintenance projects which supports the Peckforton Group in supplying potable water to Coopers Green Reservoir. As part of the £3m scheme, the project focuses on delivering resilience from Audley to maintain high quality water supply to the people in Staffordshire. Audley is […]
