An apparatus and method for separating hydrophobic materials in liquid state from an aqueous liquid or hydrophilic liquid, for separating debris from such liquid, or for purifying hydrophobic materials in liquid state are disclosed. An improved strainer for such apparatus and method is also disclosed. The apparatus and method employ at least one rotatable disk to which hydrophobic materials are attracted and retained; scraper blades to scrape the hydrophobic materials from the disk into a discharge tube from which said materials flow to a pump situated in the apparatus. The pump pumps the materials out of the apparatus. The pump is preferably driven by the same motor which rotates the disk. The strainer has an upper mesh portion and a lower portion where the walls and bottom are solid. The strainer also has an internal diverter plate. Influent containing debris strikes the plate and debris settles in the strainer and is retained in the non-mesh portion thereof. Alternatively, the strainer can be a removable, flexible strainer which, when full of debris, is emptied.
