Ceramic membranes oily wastewater treatment.

Oily wastewater treatment using a zirconia ceramic membrane a literature review 5 ceramic membranes are usually obtained by sol gel technique but also by isostatic compression reverse phase. Accordingly the fabrication of such oxide ceramic membranes requires multiple coating sintering processes which is both energy intensive and time consuming and in turn too expensive for industrial oily wastewater treatment. For ceramic membranes microfiltration process targeting wastewater treatment is promising. Discharge of untreated oily wastewaters could bring about dire consequences such as environmental catastrophes.

Many studies of membrane separation for oily wastewater treatment have been reported particularly in ultrafiltration uf and reverse osmosis ro with organic membranes. Ceramic membrane is extensively used in water and wastewater treatment which include oil field injection water paper industry waste water landfill leachate palm oil wastewater textil and printing industry wastewater oily wastewater titanium dioxide wastewater fermentation chemical industry wastewater desalination seawater treatment and degreasing liquid treatment and other aspects. The well thought out designed and implemented use of membranes can decrease capital. Nowadays integrated microfiltration mf membrane systems treatment is becoming widely popular due to its feasibility process reliability commercial availability modularity relative insensitivity in case of wastewater of various industrial sources as well as raw water treatment and lower operating costs.

Membranes review ceramic microfiltration membranes in wastewater treatment. Therefore a reduction in the cost of oxide ceramic membranes would be significant in order to improve competitiveness. However few studies are related to the application of inorganic ceramic membranes on oily wastewater treatment. Wastewater and water treatment methods include both physical methods such as sedimentation and filtration membranes media filtration and chemical methods such as coagulation ph adjustments addition of anti scalants and acids 4 5 regardless of its domestic municipal or industrial origin wastewater is a serious environmental constraint that dictates effective treatment for its safe.

In this novel study based on previous experiences on fabrication of low cost and high performance ceramic membranes for oily wastewater treatment processes cheap kaolin natural zeolite and activated carbon powder have been employed in the membrane structure to improve the pf and toc rejection.
