Ceramic Membranes For Water And Wastewater Treatment

Ceramic membrane with acid and alkali resistance high mechanical strength narrow pore size distribution and long life so it s applied in.

Ceramic membranes for water and wastewater treatment.

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. A critical review on current status and future perspectives of ceramic based membranes for water and wastewater treatment is given. 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. The demand for more chemically and thermally stable membranes in water and wastewater treatment is growing rapidly over the past few years.

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. 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. Common ceramic membranes made of alumina zirconia titania silica and zeolite are described and their advantages and disadvantages are compared and discussed. 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.

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. The well thought out designed and implemented use of membranes can decrease capital. Highly efficient and economic treatment of wastewater sludges and wastewaters in one way is a challenging issue in the water treatment field.
