Ceramic Membranes For Water And Wastewater Treatment

The well thought out designed and implemented use of membranes can decrease capital.

Ceramic membranes for water and wastewater treatment. Membranes review ceramic microfiltration membranes in wastewater treatment. 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. Bandyopadhyay ceramic membrane division csir central glass and ceramic research institute. 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.

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. Common ceramic membranes made of alumina zirconia titania silica and zeolite are described and their advantages and disadvantages are compared and discussed. Highly efficient and economic treatment of wastewater sludges and wastewaters in one way is a challenging issue in the water treatment field. 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.

Ceramic membranes for wastewater treatment p. In this review article the key types of ceramic membranes that are applied in water and wastewater treatment are described and analysed. 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.

Ceramic membrane with acid and alkali resistance high mechanical strength narrow pore size distribution and long life so it s applied in. The demand for more chemically and thermally stable membranes in water and wastewater treatment is growing rapidly over the past few years.
