ABSTRACT:
A waste water treatment system includes a first stage oil separator having a plurality of conically shaped members disposed inside an enclosure. The conically shaped members are preferably made of polypropylene. Oil within the waste water coalesces upon contacting the conically shaped members. Waste water is circulated in vortical flow paths between the conically shaped members to lengthen the flow path of the waste water between the members thereby promoting coalescence of oil. A second stage oil separator involves a bead pack container unit filled with polypropylene beads through which waste water passes to remove residual oil and debris from the waste water coming from the first stage oil separator.
