Ceramic Membrane For Water Purification

As shown in table 2 1.

Ceramic membrane for water purification.

Hence large scale membrane applications or less challenging water purification processes are still dominated by polymeric membranes. Compared with hollow fiber membrane ceramic membrane can keep on running for many years without any risk of membrane damage. Ceramic membrane filtration is a robust and sustainable technology for the production of clean and reliable water. The advantages and disadvantages of these common ceramic membrane materials are compared in table 4.

Nanoporous membrane for water purification can generally be divided into three types based on their material composition. Optimized hydraulic design for water applications. Flux of crm membrane can keep at a stable point. However the main drawback of using ceramic membranes for water treatment is their high capital cost.

In recent years ceramic membrane are more and more applied for municiple water treatment even its investment is much higher than normal polymeric hollow fiber membrane. Alumina zirconia titania silica and zeolite are five common candidates employed in producing ceramic membranes for water and wastewater treatment. Due to the removal of impurities like suspended substances turbidity bacteria and protozoans the technology is very suited as a purification step in the production of drinking water process water or for purification and reuse of wastewater. Ceramic lasts up to 10x longer.

Still now for water purification there are several kinds of membranes are developed by several researcher like ceramic zeolite mixed matrix membranes mmm thin film composite tfc thin film. Ceramic photocatalytic membranes for water filtration under uv and visible light. Best in class life cycle cost. Inorganic organic and inorganic organic hybrid membranes.

Nanostone s engineers have developed a ceramic membrane to outperform other ceramic and polymeric membranes on the market today. Action of two active surfaces in one membrane element and the overall concept and way of implementation in an efficient water purification device are already covered by a european patent.
