Oily Sludge Treatment
Most industrial processes that employ oil water separation, DAF, physical-chemical treatment or clarification require a sludge handling technology to reduce the quantity of water requiring off-site disposal. This technology generally includes chemical conditioning followed by sludge thickening and either filter presses or centrifuges to produce a solid sludge cake for disposal. The water extracted from the sludge handling process is generally recovered and returned to the head of the process for re-treatment.
PAT has designed and supplied sludge handling facilities for several industrial and municipal applications where water reuse and/or ZLD becomes a priority in the owner’s process requirements or due to regulatory limitations on liquid discharge.
