Oil Skimmer
Remove Oil & Grease from Water

Oil skimmers continuously remove floating oil, grease, and hydrocarbons from sumps, tanks, and effluent streams — improving water quality, protecting downstream equipment, and supporting reuse or discharge compliance.

Product Overview

Oil Skimmer Overview

Rototech's oil skimmers use a rotating drum, belt, or tube to pass through the liquid surface where oil adheres; the oil is then scraped or wiped off and collected in a receptacle. This mechanical separation is simple, energy-efficient, and effective for floating oils and greases in coolant sumps, ETP/CETP equalisation tanks, and process water — reducing load on downstream treatment and enabling oil recovery where applicable.

Key Features

Continuous Operation

Runs 24/7 to maintain low surface oil concentration and protect pumps and filters.

Minimal Water Pick-Up

Designed to lift mainly oil, reducing disposal volume and improving recovered oil quality.

Easy Installation

Mount on sump or tank; various belt/drum materials for different oil types and temperatures.

Working Principle

A rotating element (drum, belt, or tube) is partially submerged in the liquid. Oil and grease adhere to the surface due to affinity; as the element rotates out of the liquid, the oil is scraped or squeezed off into a collection tray. The cleaned element re-enters the liquid to pick up more oil. No chemicals are required; operation is purely mechanical and can be adjusted for flow rate and oil viscosity.

FAQ

Oil Skimmer Questions

Yes. Oil skimmers are widely used on coolant sumps and process tanks to continuously remove floating tramp oil and grease, helping extend coolant life and reducing load on downstream treatment.

Skimmers are most effective on free-floating oil layers. For strong emulsions, we recommend pretreatment (like chemical breaking, coalescers, or DAF) so the oil can separate and be skimmed efficiently.

Recovered oil is wiped/scraped into a collection tray or pipe and discharged into a drum or container. It can be reused where applicable or disposed as per your waste handling norms.

Share tank dimensions, access/mounting details, oil type (light/heavy), temperature, flow or turbulence, and expected oil loading. Based on these we recommend belt/drum/tube type and capacity.
