The Oil Grabber Model 8 oil skimmer from Abanaki is designed to remove oil from sumps in hydroelectric plants. Rugged construction increases the life of the skimmer, which is said to require little to no maintenance. It utilizes a continuous belt and wipers to remove virtually all oil, and an optional oil concentrator is designed to eliminate residual water.
The belt skimmer can be part of an emergency oil spill system, in which wastewater flows though a coalescer tank, is skimmed and passes though filters. According to the company, the system satisfies government standards for preventing oil spills from entering the environment.
Another product, the Oil Viper tube skimmer, is said to effectively remove floating surface oils via an oleophilic (oil-attracting), 3/4"-diameter, continuous-looped tube. The tube extends over the surface of the tank or pit and collects free-floating hydraulic oil and other oily hydrocarbons. A specially designed wiper system that removes oil from the tube ensures that it is a virtually oil-free tube as it leaves the skimmer, speeding oil removal. The skimmer can remove oil at rates ranging to 100 gallons per hour.
