Carlin Construction was the general contractor on the job. The Grit System is located in the headworks just after the mechanical screens. The Septage Receiving System is in an underground tank adjacent to the headworks of the plant. The TFA’s are located right above the grit screw. There are 10 TFA1.50 diffusers. The diffusers create a rolling action in the tank to wash the organics from the grit particles; the diffusers are mounted ~3’ above the collection zone allowing the grit to settle out. The piping material for this application is Schedule 10 316L stainless steel. This is the isolation valve located at the top of the drop pipe. This type of system is a removable manifold configuration constructed entirely of schedule 10 SS. The Contractor is in the process of adjusting the diffusers to their correct alignment. This is a “fixed mounted” type configuration. Total 12 diffusers. (6) TFA1.50 on each side. All angled uniformly so the air is evenly distributed. Orifice plugs are also used to evenly distribute the air to all valves. Tideflex uses all Victaulic Brand couplings (304SS & 316SS) for the connections within the stainless steel systems. Fill out an Application Data Sheet and Tideflex Engineers will size up a system for you. They will supply detail CAD drawings and sample specifications. A complete evaluation will be included.
