We can assist you to diagnose problems and provide solutions to resolve them. Our qualified technicians are experienced in working on all types of oil water separators in a variety of industries. Contact Cleanawater for more information about troubleshooting your oil water separatorĮxpert advice and technical support are close at hand with Cleanawater. If the problem persists, arrange for servicing of the unit by Cleanawater technical experts. There is a smell coming from the oil water separatorĬheck all basic operating conditions as you would for a hydrocyclone separator – read more here. Finally, check media packs and clean as per operations and maintenance schedule. Thirdly, there may be a formation of emulsions which would require investigation by Cleanawater experts. Secondly, the waste oil decant tank may be full. Firstly, an oil spill may have overloaded the system. There are 3 potential causes of oil being carried over to the water outlet stream. There is oil present in the water discharge These and pump overload checks are described in more detail in our article for hydrocyclone oil separators. Problems related to switching the equipment on or off are usually related to electrical or control panel issues. The pump overload keeps tripping and system switching on/off issues Contact Cleanawater for technical support to handle emulsions. Make sure no unapproved degreasers and detergents are being used in the system. Oils have formed an emulsion in the waste water stream and cannot be removed by a coalescing or vertical gravity separator. The waste water stream is clean and therefore no oil is being collected. The collar should be set to five millimetres above the water level when the pump is running to ensure that oil is removed from the system and does not build up inside the separator. The waste collar inside the unit may be set too high. There is no oil in the waste oil container Excess flow rate through the unit negatively affects its performance. Regular blockages may need further investigation into the unit sizing and removal of solid debris. Check media packs, and clean as necessary.

The collar should be set to five millimetres above the water level when the pump is running to prevent free water from being skimmed off with the waste oil. The waste oil collar inside the unit may be set too low. Water is flowing into the waste oil container, or water is flowing out of the top of the separator

For details on how to check these systems, refer to this article that addresses hydrocyclone separators too. Some of these issues are common to any kind of separator.
