Due to seasonal demands on an existing sewage works at Rampton village Nottinghamshire, Severn Trent Water requested WPL offer a solution to assist meeting consent standards.
The WPL Clic-Clo 5 FBO Microcreen tertiary polishing plant solution meets the highly variable peak flow and load. WPL allowed maximum in-flow capacity with total suspended solids @ 100mg/lt (95%ile) due to peak flow during the ‘sloughing season,’ when dead biomass is washed off the trickling filters.
Andrew Haywood, Utility and Industrial Sales Manager at WPL states “Severn Trent Water has used microscreens from WPL previously for both permanent and portable applications to great success.”
The WPL Clic-Clo Microscreen tertiary polishing plant is an ideal solution due to its compact size, low maintenance regime, minimal mechanical and electrical installation requirements and plant reliability – all designed to improve whole life costs.
The plant is due for delivery April 2015.
