Out With The Old, In With The New Removal of old baffle curtains and installation of new Reg 31 approved curtains for a service reservoir tank Due to a bad state of repair, an underground concrete structure required the old baffle curtains to be removed along with repairs to existing stainless 316L baffle plate and the Installation of Reg 31 approved flexible membrane to improve contact time. Let's go! Client Water Utility Company Project objective To create a controlled flow of treated water around the service tank Project description Once the old baffle curtains had been removed and repairs made to the existing stainless 316L baffle plate, installation of the new baffle curtains could begin. The new prefabricated 1.5mm Flagon GeoP/AT baffle curtains are shipped to site and placed inside the tank to the exact positioning of the old curtains. To place these in the tank, the baffle curtains are hoisted up from the floor into a vertical position and then each curtain is fixed to an eyebolt from the soffit by a baffle strap which are used for tensioning. The baffle curtains are fixed to the floor slab using a 316L stainless bar and fixings which provides a positive seal and reduces short circuiting. The curtain panels are individually pulled up and welded onto the newly installed curtain using hot air welding techniques. Statistics 3 weeks required turnaround 7 lanes of corridors 1600 sq.m of complex welding used (approx) 1500 sq.m of Reg31 baffle curtains 10m – 50m varying lengths of curtain Deadline met. We completed this work in the 3 week turnaround required by the water utility company to finish the project including necessary testing and to return the tank to service. The new baffle curtains are manufactured off site to improve the efficiency of installation on site. 7 lanes of corridors with approx 1600sq.m of complex welding were used. 1500sq.m of Reg31 baffle curtains were used On completion, curtain lengths can vary between 10m – 50m long.
