A Belt Mop Oil Skimmer is a non-oleophilic mechanism employed to skim oil from coolant and wastewater. Non-oleophilic skimmers are distinguished from oleophilic skimmers by the component used to collect the oil. In the case of a belt mop oil skimmer, the belt is used in applications where an oleophilic material, such as a rope, drum, or disc, is inappropriate. Since Belt Mop Oil Skimmers are used in harsh conditions, the skimmer is generally turned off whenever there is no oil to skim thus minimizing the amount of water collected. Belt Mop Oil skimming elements are nearly as efficient as oleophilic skimmers when oil is present and removes a high volume of oil. The skimmer works on the difference in surface tension of oil and water allowing the rotating continuous belt to attract waste oil and reject water.
