(Alam tanks must be bound with corrosion resistant material (HDPE Lining, Bitumen Coating, tiles etc) 2) Flash mixer equipment with SS 304 material made stirrers & paddles for chemical resistance. 3) Filtration plant equipment instrumentation and piping. 4) Clarifloccualation equipment (with stainless steel blades) with rotating bridge arrangement etc.,The equipment consists of following components a) Flocculator Drive Mechanisms These will consist of suitable H.P geared electric motor mounted on M S Frame work on bridge platform. b) Flocculating Mechanisms and raking in the flocculation compartment . These will consist of vertical M S shafts and arms, wooden paddles, guides, bearings etc with stainless steel bush bearing for the shafap at the bottom. The paddle area shall be between 10 to 25 % of the cross section of flocculating zone. c) Mechanism for raking in clarifier compartment. d) Revolving Bridge This will be made of M S sections with torsion proof fabrication of required length and width of 1.22 m. The scrapper frame work of M .S section shall be hung from bottom of the bridge. The Bridge will have an outer travelling trolley. The walk way will be 1.22 m wide and shall have chequered plates. The web of the bridge structure shall perform the function of hand railing on both the sides also. The scarping plates will be fitted with the scrapper frame work with hinges and stainless steel pins and will be fitted 12 mm thick rubber ledging . The scrapers will be so adjusted as to ensure smooth and even scarping of the floor. e) Bridge Drive The Bridge will be driven by an electrically operated geared motor with suitable H.P f) Bridge Drive Mechanisms This will consist of two nos of steel wheels driven by electric geared motor. The wheels will be fitted on the trolly with necessary bearings, pedestals etc . These wheels travel along the periphery of the clariflocculator tank on rails. g) Electrical Arrangements These will consist of electrical cables PVC insulated with copper wires run from the main switch board provided in the chemical store and run under the tank and along the central column. The cable will be connected to the central slip arrangements. The electric geared motors will be controlled from the control panel fitted on the bridge with necessary weather proof housing cabinet with necessary cables, wires, starters , switches etc . 5) Stainless steel wheel shall be provided for the bridge clariflocculator. 6) Wash water tank fittings and pumpsets with 100% stand by.
