Oily Sludge Treatment

Sludge Handling

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.

Biological Treatment

In addition to conventional biological treatment for sanitary water treatment applications, this process is also employed to treat specific contaminants in industrial water applications. Each biological treatment process is custom designed for industrial use. For sanitary wastewater applications standard biological processes are available including that required for MBR applications.
