Brightwork Moving Bed Filter
Download the brochureAchieve consistently high‑quality effluent, even under challenging loads, supported by intelligent Sand‑Cycle® monitoring for total process visibility.
The Brightwork Moving Bed Filter (MBF) is an advanced continuous moving bed media filtration system that delivers stable, predictable treatment performance, even under varying hydraulic and solids loads. Its integrated Sand‑Cycle® smart monitoring and control system provides engineers with real‑time insight into filter operation, helping them quickly pinpoint developing issues and avoid potential non‑compliance with effluent discharge permits.
Hydro International and Brightwork BV have partnered to combine UK water industry expertise with leading Dutch filtration innovation, delivering advanced tertiary treatment solutions that support smart, reliable, compliant and future‑ready wastewater performance.
The Brightwork MBF is an high-performance, moving bed media filtration system with integral Sand-Cycle® smart remote monitoring and control to help water companies ensure that final effluent is compliant with their permitted limits.
The Brightwork MBF is designed to handle varying hydraulic and solids loads while excelling in both solids removal and biological conversion, making it a robust, adaptable solution for wastewater treatment plants of any scale. The system is modular in design with components built off-site and ‘plug-and-play’ for easy installation, significantly reducing design and installation time and costs.
Applications
- Wastewater treatment
- Process water production
- Cooling water conditioning
- Surface water treatment
Reduce design and installation costs
The Brightwork MBF is modular in design which significantly reduces design and installation costs and simplifies project delivery.
Get real-time visibility of performance
The integrated Sand-Cycle® system allows operators to monitor performance on unmanned sites via an online visualisation portal.
Rely on stable, consistent performance
The Brightwork MBF reliably handles variable hydraulic and solids loading, maintaining stable operation.
The Brightwork MBF is an upflow media filter, removing particles in the pores of the filter. It may also function as a carrier for biomass for biological conversion applications.
An air lift pump continuously conveys the sand to the sand washer. The air lift pump has a turbulent operation, which starts to separate impurities from the sand. The sand washer further cleans the sand with a flow of clean water. Clean water is discharged via the outlet at the top of the system and separated solids are discharged via a piped outlet. The clean sand drops back down onto the top of the sand bed, starting the cycle again.
Sand-Cycle® monitoring and control
Sand‑Cycle® uses RFID tags, similar in principle to those used for pet microchipping. These tags are mixed into the filter media.
As the tags move with the media, they act as a reliable proxy for sand circulation. Field data is continuously collected and processed to calculate meaningful process parameters, which are displayed via clear, intuitive dashboards.
Operators gain real‑time visibility of key operating conditions, supporting faster decisions, improved performance and greater confidence in filter operation.
Brightwork MBFs are designed modular systems and may be applied in a wide capacity range. Standard filters are available from a capacity as small as 4 m3/h up to and over capacities of 4,000 m3 /h.
Single stand-alone units are typically constructed in stainless steel. For large filter plant capacities, typically from 1,000 m3/h onwards, rectangular and circular concrete units are applied.
Brightwork MBF plants are configured, based on similar modular units, to accommodate the operating window and to meet the required consent levels. Dedicated process design tools are used to determine the most economic lay-out.
