At a Canadian oil production facility an oily waste water treatment system is using oil adsorption media technology. CleanFlow was asked to provide a solution in order to protect the oil adsorption media from clogging with dirt and solids. We selected the robust and efficient automatic self-cleaning screen filter with suction scanner cleaning mechanism. The filtration degree of the automatic filter is 20 micron which is well below the requirement to prevent clogging of the oil adsorption media. Special considerations had to be made for the -25 degree Celsius freezing temperatures that occur. The automatic filter unit was installed in a skid frame for quick and easy mobilization and installation.
