Oil Skimming/Separation System

This Model ACE 20 / 40 HI-RISE LLS™ Liquid/ Liquid Separator and Hunter Oil Skimmers removes floating liquid fuels and oils from several wastewater retention basins simultaneously. This installation is at the wastewater treatment plant of a large passenger railroad. Detergents do not affect the efficiency of the skimming/ separation system.

Dual inflow rates may vary from each pump, with two pumps operating at the same time for a total system operating capacity of 40 gpm. The separator can store over 1,000 gallons of recovered oil.

Air-operated double diaphragm pumps draw the surface fluids from the basins and through the Hunter Oil Skimmers. Action Engineering high-volume Trash Strainers protect the pump inlets from floating debris. The system has no moving parts.

Oil is harvested during system operation. Accumulated solids are removed during system shutdown through quick--cleanout flanges, which are standard on all units. Optional heated, insulated units permit operation on wastewater ponds containing gelled, floating oils.

HI-RISE LLS™ Liquid /Liquid Separators and Hunter Oil Skimmers are installed and operating at railroad refueling sumps, washyard sewers and wastewater retention basins. Other applications include industrial laundries, power-generating station wastewater retention basins and metals-processing plants.
