An economical ABOVE GROUND CLARIFIER system designed to simplify EQUIPMENT and installation cost Model SDS Above-Ground Clarifier or Sewer Discharge System is a small and compact clarifier system designed to save space and save installation time. The system includes a minimum of (3) separate small foot-print flat bottom poly tanks mounted on a corrosion-resistant aluminum stand. Each tank is plumbed to maximize the flow path and dwell time. Each tank is plumbed on the bottom with either manual valves or optional automatic valves to enable purging sediment from the bottom of the tanks.
As water flows through the tanks sediment will drop out and oil will tend to float on the surface where it can be skimmed off through oil skim valves or adsorbed into floating oil pillows. The system is designed with oil coalescers provided in the first two stages to maximize oil/water separation which causes oil to float to the surface. The cleanest water will exit the system by gravity to the sanitary sewer. As an option the cleaned water can first be deposited into a Sample Barrel and then be pumped out under pressure via a sump pump mounted inside the Sample Barrel. Oil bleed valves are provided with each stage to allow removal of free floating oil which has worked its way to the top.
