Project Description
The FilterClear installation at Bolsover forms part of the national CIP program, to ascertain the feasibility and real costs associated with achieving low (0.5 mg/L) to ultralow (0.1 mg/L) total phosphorus consents. The project has entailed us working closely with the main contractor Eric Wright, consultant Arup and Yorkshire Water to build a chemical dosing and tertiary treatment plant with the target of 0.1 mg/L TP. As part of the ongoing optimisation the plant operated with first point dosing only and achieved TP concentrations around 0.2 mg/L. The trial is in its early stages and initial results both with and without second point dosing are very encouraging. The FilterClear skid was fully assembled and tested off-site in our fabricator’s works in Chesterfield, including the HMI software by MCS. Following the FAT the skid was transported to site, installed on a flat slab in February and commissioned by 31st March.

Project Highlights
- Off-site manufacture
- Ultra-low TP
- Rapid installation and commissioning
Scope of Works
BwB supplied one of its proprietary triplex FC 3v1840 FilterClear skid and associated control system, and provided design, commissioning and training services. The main contractor, Eric Wright, built a concrete slab and provided associated connecting pipework and power supply cabling for the installation of the FilterClear skid.
