Oil Skimmers for Municipal Wastewater Treatment Plants: Meeting Discharge Standards

Oil and Grease Challenges in Municipal Wastewater

Municipal wastewater treatment plants (WWTPs) receive industrial discharge, commercial kitchen grease, and stormwater runoff containing oils and hydrocarbons. Oil and grease interfere with biological treatment processes, foul membranes and filters, and must be removed to meet effluent discharge limits. Vens Hydroluft provides reliable oil skimming solutions to municipalities worldwide, helping plants achieve consistent compliance with environmental discharge standards.

Oil Skimming at Each Treatment Stage

At the headworks and primary clarifiers, slotted pipe oil skimmers remove bulk floating oil. In equalization basins, belt oil skimmers or Vens ORBIS Pro multi-disc skimmers provide continuous surface cleaning. For sludge lagoons, floating drum skimmers handle varying water levels. Final polishing is achieved with coalescer oil water separators to meet the strictest discharge limits. See WWTP installations on our YouTube channel and contact us for WWTP solutions.
