Pilot Plant Storage Tanks The pilot plant requires the purchase of 8 storage tank units which range in size and application from 500 gallons to 3,000 gallons. The storage tank units should be purchased as follows: Tank Backwash Minimum Size allons 500 Service Settled Water Material Polyethylene Minimum Inlet/Outlet Size 3 inch Settled Water 2,100 Settled Water Polyethylene 4 inch Lake Return 500 Settled Water/Filtrate Polyethylene 3 inch MW & CIP Waste 3,000 Chemical Polyethylene 4 inch MW & CIP Waste_ _ _3,000 Chemical Polyethylene 4 inch SettlingTank 3,000 Solids HandlingPolyethylene _ 3 Recycle Water Storage 2,500 Solids Handling Polyethylene 3 Solids Storage 3,000 Solids Handling Polyethylene 3 Based on preliminary layouts, it appears the settled water, both chemical tanks, settling tank, recycled water storage, and solids storage tank will need to be located outdoors near the administration and shop building. Backwash. Tank.. The 500 gallon backwash tank will receive the backwash waste flow from the membrane pilot units. A submersible type pump will be required in the backwash tank to pump the backwash waste back to the raw water supply line at the head of the pilot plant. The tank needs to be open top or be provided with a large enough opening in the top for installation of the backwash return pump. Lake Return Tank The 500 gallon lake return tank will receive flows from the 6 -inch filtrate header. Minimum size for the inlet, outlet, and overflow is 3 -inch diameter. A 6 -inch lake return line will return flow back to the lake. The discharge of the lake return line into the lake should be located at a minimum of 500 feet from the existing intake structure. MW and CIP Waste Tanks (2) Two 3,000 gallon MW and CIP Waste tanks will be required to collect the waste from the membrane pilot units for suitable disposal off-site. One tank will hold acidic waste and the other will hold hypochlorite and caustic waste. Both tanks will require 4 -inch minimum inlet and outlet fitting connections which are typical maximum inlet/outlet sizes. Outlet fittings need to be coordinated with the connection to the truck to be used for disposing of the waste. Provide overflows from each tank to the existing reverse osmosis (RO) concentrate pond. 07/25/2008 Page 3 Settled Water Tank The 2,100 gallon settled water tank will receive flows from the plate settlers and provide settled water to each of the membrane pilot units. Maximum water level in the tank should be 6 feet or less. Inlet, outlet, and overflow connections need to be a minimum of 4 -inch diameter. Provide a ''/s" sampling valve on the tank inlet and a drain connection on the outlet from the tank. Provide a 4 -inch bypass around the tank. Settling Tank Settled solids from the plate settler unit will intermittently discharge by gravity into the 9 foot diameter settling tank. The settling tank should be located so the water level is I to 2 feet below the high water level in the plate settler so that solids from the plate settlers can be discharged by gravity into the settling tank. The maximum water depth in the tank should be 6 feet. The settling tank will be equipped with a settled water header at the base of the tank to withdraw solids. The settled water header shall be constructed from 2 inch PVC pipe with % inch drilled openings spaced at I foot intervals as shown on Figure 1. The settling tank should be equipped with a 3 -inch influent line from the plate settlers, a 3 -inch settling tank overflow, and a 3 -inch effluent connection for the solids removal header. Solids from the settling tank will be pumped to the solids storage tank. Provide a drain connection on the outlet from the tank. Recycle Water Storage Tank Settling tank overflow will discharge into the 9 foot diameter recycle water storage tank. The maximum height of the tank should be 5 feet with maximum water level of about 1 foot below the water level in the settling tank. The recycle water storage tank should be equipped with a 3 - inch opening to receive the overflow from the settling tank, a 3 -inch overflow connection, and a 2 -inch recycle water effluent at the base of the tank. The recycled water will be returned to the plate settlers. Provide a drain connection on the outlet from the tank. If necessary,. recycled water may be used for irrigation purposes. Solids Storage Tank The solids storage tank will receive solids settled in the settling tank. Solids will be hauled away or discharged to the existing RO pond during emergency conditions. The tank should be provided with a 2 -inch influent connection for the solids removal line, a 3 -inch overflow connection and a 2 -inch effluent connection. Outlet fittings need to be coordinated with the connection to the truck to be used for disposing of waste. The truck connection may serve as the drain for the solids storage tank. Raw water supply line A water supply of 220 gpm will be pumped from Lake Alan Henry at the existing intake structure near the dam and conveyed through a raw water line to the pretreatment units. The pipeline would consist of a 4 -inch hose from the supply pump to the platform and 6=inch PVC or /z HDPE pipe to the pretreatment units. Provide a '" sampling valve in the raw water supply line upstream of any chemical feed and backwash return. 07/25/2008 Page 4 Plate Settler Pilot Units Two plate settler pilot units which are self-contained, complete with chemical feed equipment, inline mixer, 3 stage flocculators, inlet diffusers, plate settlers and sludge removal equipment have been selected. Install plate settlers as follows: • Place level pad near the north end of the administration and shop building with minimum dimensions of 10 feet wide by 25 feet long for each plate settler unit. Acceptable pad materials would be well compacted road base, asphalt, or concrete. The tank bottom must be fully supported. Confirm that units are mounted at a high enough elevation to permit gravity flow of the effluent to the settled water tank and gravity flow of the sludge to the settling tank. Install handrails provided. • Install static rapid mixer, inlet throttling valve, and inlet flow meter at inlet to each unit and electrically actuated sludge outlet valve at sludge outlet if not already installed when delivered. • Install raw water supply piping, outlet piping to the settled water tank, and sludge outlet piping to the 9' diameter settling tank for each unit. • Install chemical feed system inside the administration and shop building and feed piping to feed points on plate settlers. • Make electrical connections to plate settler including controls, drive motors, sludge collector, and flow meters as required. Provide power to chemical feed equipment. Raw Water Supply Pumv A single submersible type pump will be supported from the bridge near the existing intake. The raw water pump data is as follows: Type .of Pump.........,. Submersibles .., . Number of Units i plus 1 spare available Rated total head, ft 115 Capacity at rated head, gpm 220 Horsepower 20-25 (Varies by Model) The ITT Flygt NS3153 pump or ITT Goulds 4NS pump are recommended for this application. The pump should be selected and purchased by the City of Lubbock. The ITT Flygt pump is available through J&L Equipment and the ITT Goulds pump is available locally through Global Pump and Equipment. The lead times vary by manufacturer and may be as long as 6-8 weeks. Raw Water Strainer The City of Lubbock should purchase and install a raw water strainer, to be located upstream of the plate settlers, for removing debris from the raw water. The strainer should be a simplex basket type strainer with a 4 -inch inlet/outlet and a 3/16 -inch perforated basket. Strainers are available in both PVC and Cast Iron with plastic or stainless steel baskets. Provide reducers and increasers as required to connect to upstream and downstream piping.
