ceramic membranes



What is Ceramic Membrane?

Ceramic membranes are identified as artificial inorganic membranes, used for liquid filtration. These membranes are made from the materials like alumina, zirconia oxides, titania, silicon carbide, and others. Compared to traditional polymeric membranes, ceramic membranes offer better application and efficiency because of its resistance to aggressive media. Therefore, ceramic membranes allow separations involving acids and strong solvents. These ceramic membranes for water treatment offer other beneficial features too such as thermal stability, chemical stability, low operation cost, long life, and more. Due to this, ceramic membranes are considered the best for obtaining high-quality and high-endurance liquid filtration in industrial environments.

How does it work?

A range of undesirable objects in the water such as suspended solids and particles, oil droplets and emulsions, bacteria, etc. are eliminated from the liquid. When the feedwater enters the ceramic membranes, it separates the permeate and concentrates. The ceramic membranes filtration leaves behind pure and clean fluid, at different levels as per the filtration requirements and pore size. The water filtration ranges are microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Microfiltration and ultrafiltration are low-pressure filtration ranges in which a semi-permeable membrane eliminates suspended solids, colloids, viruses, etc. and delivers a pure liquid. Nanofiltration and reverse osmosis are sensitive filtration involving partial separation of salts. The pore size of membrane is key to determining the filtration range.

Advanced ceramic membrane Filtration Process

Industrial liquids enter the ceramic membranes in the advanced ceramic membrane filtration process. The filtration process creates pressure, and the feed water passes through the membranes. The permeate moves through the membrane and becomes the filtered liquid:

  • The permeate passes through the conventional filtration method to eliminate pollen, coal particles, yeast, sand, hair, etc. Then it passes through the microfiltration method to remove bacteria, black carbon, oil emulsions, fat globules, casein micelles, viruses, asbestos, etc.
  • In the ultrafiltration system, the membrane eliminates finer components like synthetic dyes, sugar, more viruses, etc.
  • In Nanofiltration and reverse osmosis, aqueous salts, sugars, ions, and more are removed.

Even the concentrate goes under processing for reuse after recycling. In the filtration process system, all the parts have a significant role.

Ultrafiltration for Wastewater treatment

Ceramic Membrane Manufacturers ensure to make high-quality membranes to allow fine ultrafiltration for wastewater treatment. With this kind of fine liquid filtration by the ceramic membrane and not polymeric membranes, the industries can optimize their operation by separating permeate from concentrate at a low cost. In the ultrafiltration method, particles such as bacteria, viruses, black carbon, oil emulsions, fat globules, casein micelles, asbestos, synthetic dyes, sugar, etc. are removed. The diverse properties of ceramic membranes like chemical stability, mechanical stability, thermal properties, corrosion resistance, etc. make them perfect for ultrafiltration purposes. These membranes can be rewashed, used with harsh cleaners, sterilized at high temperatures, etc. This kind of wastewater treatment is necessary for a sustainable future and cleaner water.
