The tank contains chemical rock whose functionexterior wall liner is a solution. The exterior liner is provided is to perform the neutralization of the acidic wastewater.on the concrete outer wall. Some common lining materials The chemical rock consists of lump limestone orinclude; Bitumastic Waterproofing, Fiber Reinforced marble 1 to 3 inches in size and should have a calciumPolyester, High Density Polyethylene, or Polypropylene.carbonate content of at least 92 percent. The chemical rock is expendable during normal operation. StandardLeak detection systems are available to detect primary tank sizes are 30 to 2000 gallons.tank or pipe leakage or groundwater seepage.15 Gallons Sampling Tank: This tank is constructed ofThe Neutralization Tank is gas-tight, therefore ventinghigh-density polyethylene. The tank houses a pH sensoris required. During the neutralization process theprobe for the sampling of wastewater effluent from theby-product is carbon dioxide gas that is not toxic,Acid Neutralization Tank. The corresponding pH analyzercorrosive, or flammable. Venting will allow for the removal is identified as Primary System at the control panel. of any vapors. Venting is typically accomplished by routing a vent pipe from the tank to the building vent system.Wet Sump: The wet sump is located in the floor of the concrete vault. As the name implies, this sump mayWhen pH monitoring and/or leak detection is required, contain water. A sump pump is located here. As waterseveral options are available. For budget projects, a visual accumulates, the pump will automatically transfer waterdetection system consisting of an access cover or pipeinto the sewer. A buoyancy sensor will detect high waterin the secondary tank is available. Routine inspectionlevel in the secondary vault in the event of pump failure.is required to ensure warning in the case of a leak.For automatic notification, an electronic pH monitoring Control Panel: The control panel is equipped with and leak detection system is available. This system consists pH/conductivity analyzers and a digital chart recorder.of sensor probes, analyzers, digital chart recorder and Monitoring data is digitally recorded to a memory cardnotification panel.

In general laboratory PSI @ 28 days. Pre-casting the concrete shell ensuresapplications like schools or hospitals, 10 gph per stationthat all units achieve structural and physical uniformity.of effluent discharge is used.The units are structurally engineered for H-20 truck loading and can be buried without any need for any other structural protection. The unit is of monolithic construction at the walls and bottom to insure against joint leakage.Acid Neutralization Tank Model ANMS SizesLABTANKNEUTRALIZATIONNEUTRALIZATIONMAXIMUMNUMBER OF LAB MODEL FILL IN LBS FILL IN CUBICGALLONS EFFLUENTSTATIONSFEET GAL/HRANMS-0030 400 4 30 60 6ANMS-0050 700 7 50 100 10ANMS-0100 1,300 12 100 200 20ANMS-0150 2,000 20 150 300 30ANMS-0200 2,700 27 200 400 40ANMS-0250 3,300 33 250 500 50ANMS-0350 4,700 47 350 700 70ANMS-0500 6,700 67 500 1,000 100ANMS-0700 10,000 94 700 1,400 140ANMS-0800 10,700 107 800 1,600 160ANMS-1000 13,400 135 1,000 2,000 200ANMS-2000 26,700 267 2,000 4,000 400378 [email protected]|888-611-7275|WWW.PARKUSA.COM'
