Ceramic membranes for water and wastewater treatment.

Membranes review ceramic microfiltration membranes in wastewater treatment. The well thought out designed and implemented use of membranes can decrease capital. A critical review on current status and future perspectives of ceramic based membranes for water and wastewater treatment is given. Ceramic membranes have been at the epicenter of recent advances and research in membrane development and further growth in the area of water and wastewater treatment with the scope being focused in results being geared towards creating a greater membrane area without compromising mechanical strength.

Common ceramic membranes including those made of alumina zirconia titania silica and zeolite are presented first where their advantages and disadvantages are compared and discussed. In this review article the key types of ceramic membranes that are applied in water and wastewater treatment are described and analysed. Bandyopadhyay ceramic membrane division csir central glass and ceramic research institute. Highly efficient and economic treatment of wastewater sludges and wastewaters in one way is a challenging issue in the water treatment field.

Herein we present a waste to resource strategy for rational fabrication of low cost ceramic membranes which simultaneously addresses the treatment of heavy metal laden sludges and the separation of oil in water o w emulsions. 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. Common ceramic membranes made of alumina zirconia titania silica and zeolite are described and their advantages and disadvantages are compared and discussed. The cold emulsion wastewater treatment is the most difficult the general treatment of oily wastewater are flotation adsorption biological chemical etc but are difficult to get good treatment effect.

As a result ceramic membranes are increasingly applied due to their inherent advantages over conventional polymeric membranes such as good chemical stability favorable mechanical strength high surface hydrophilicity if desirable good antimicrobial. Ceramic membrane with acid and alkali resistance high mechanical strength narrow pore size distribution and long life so it s applied in.
