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.
