Ceramic Membranes Oily Wastewater Treatment

Discharge of untreated oily wastewaters could bring about dire consequences such as environmental catastrophes.

Ceramic membranes oily wastewater treatment.

In order to address this problem a photocatalytic membrane reactor pmr comprised of tio 2 γ al 2 o 3 modified ceramic membrane was prepared for treatment of synthetic oily wastewater under uv illumination the structure morphology and phase composition of the layer of modified. Therefore a reduction in the cost of oxide ceramic membranes would be significant in order to improve competitiveness. This article presents the review of ceramic membrane for the treatment of oily and chromium wastewater. 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.

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. However few studies are related to the application of inorganic ceramic membranes on oily wastewater treatment. The well thought out designed and implemented use of membranes can decrease capital. Among various wastewater treatment processes ceramic membranes have the edge to treat oily wastewater and separate chromium from waste streams.

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. 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. 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. 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.

For ceramic membranes microfiltration process targeting wastewater treatment is promising.
