FM Environmental recently completed the installation and commissioning of a new Grit Plant in Banbridge WWTW.
The driver for this project was to remove grit / gravel / stones, as much as possible from the influent, to avoid un-necessary deterioration of down stream equipment, such as the FFT Pumps and other assets.
The new Grit Plant, which was constructed off-line, involved a substantial dig (>9m excavation depth), lower and upper concrete chamber construction, through-flow and by-pass channel construction, and specially fabricated DN700 pipe connections, to allow integration into the pre-existing pipeline.
This was followed by full MEICA installation of the grit paddle, motor, gearbox and walkway, isolation penstocks, flooring, handrail, air-lift blower, Grit Classifier, control panel and all associated wiring.
Following full installation, commissioning flows were diverted through the new Grit Plant with initial signs being very good, with good volumes of grit being removed.
This project was a collaborative success with input from NI Water, McAdam Design, FM Environmental and Lowry Building and Civil Engineering.
FM Environmental would also like to thank their supply chain, Jacopa, Pronto Automation and M&M Steel Fabrications and also acknowledge their own Project Management staff and site team, who contributed greatly to the overall project.
