The rope is pulled back to a housing unit where the oil is wrung out and collected in a tank. The rope is then sent back to the pit surface to collect more oil.]]> Mon, 17 Sep 2007 00:00:00 +0300 http://www.au.all.biz/g473/ http://www.au.all.biz/g475/ This skimmer is similar to a rope skimmer, but a belt is used, typically 300mm (11.8 in) wide. The belt will wear out and require periodic replacement]]> Mon, 17 Sep 2007 00:00:00 +0300 http://www.au.all.biz/g475/ http://www.au.all.biz/g477/ Rotating discs are used to attract oil. The collected oil is scraped off and the oil pumped to a collection tank. These units generally float on the surface of the water but larger installations may use fixed units. A very similar design is the drum skimmer, which utilises a rotating drum rather than an array of discs.]]> Mon, 17 Sep 2007 00:00:00 +0300 http://www.au.all.biz/g477/
