How Ceramic Membranes are helping purify polluted water in rural areas ?
Ceramic membranes have been widely used in areas that are polluted with heavy metals like arsenic & iron. They are used in rural areas to convert wastewater into potable drinking water. Other than this, ceramic membrane technology is widely used in various non-water applications also like the food & dairy industry, chemical treatment, oil-water separation etc.
Ceramic membranes have a lifecycle of 10-15 years which is very high compared to traditional water treatment solutions.
Ceramic Membrane Features
• The membrane filters separate the contaminants from water and make it pollution-free. Reverse osmosis, ultrafiltration, and nanofiltration can be used in a membrane while carrying out various filtration processes.
• Ceramic membranes are made of inorganic raw materials like alumina, titanium, zirconium oxides, silicon carbide, etc.
• Unlike polymeric membranes, ceramic membranes can be used in separations in the presence of aggressive media like acids and strong solvents.
• Due to the excellent thermal stability, it can be used in high-temperature & high-pressure membrane operations.
• They are either dense or porous, just like polymeric membranes.
• Ceramic membranes have a lifecycle of 10-15 years which is very high compared to traditional water treatment solutions.
How does Ceramic Membrane ensure pollutant-free water for rural areas?
The ceramic membrane filtration system can generate clean and clear potable drinking water for rural areas. It eliminates impurities like heavy metal and turbidity in raw water from rivers and wells. It ensures the highest level of water treatment by complying with the NGT standards.
Inorganic membranes such as ceramic membranes can effectively treat complex effluents. The properties like high efficiency, durability, stability, and resistance make it the ideal solution.
Also, there are several liquid separation needs where the ceramic membranes are used extensively. Ceramic membranes use materials like alpha-alumina or silicon carbide. It has multiple inorganic membranes such as aluminium oxide, titanium oxide, zirconium oxide, or silicon carbide. The tubular, flat sheet, monolithic hollow fiber, and various layers of the ceramic membrane are also present. While the Flat sheet membrane is a membrane coating outside, the tubular membrane channels work inside the membrane coatings.
Ceramic membranes can also be used as a pre-filter to Reverse Osmosis (RO), which ultimately will reduce the load of the RO.
IPNR Endura Ceramic Membrane
H & R Johnson with CSIR-NIIST & CSIR-CGCRI has launched The National Water Mission. Their vision is to supply cheap potable drinking water to every village in the country.
IPNR Endura Ceramic Membrane is characterized by
