Wastewater treatment has become an integral part of any industrial plant today. No matter what industry it is, owing to certain newly implemented laws and regulations, and also contributing to the saving and proper reusing of an important resource, wastewater treatment through membrane filtration has become a common thing nowadays. The use of membrane filtration for treating wastewater has increased over the years and is a process where wastewater is passed through a membrane to make it ultrapure.
Membranes for filtration process are normally made from “polymeric” substance however, a new substance is being used to make these membranes. Ceramic membranes for water filtration are in the trend now and has become the most preferred alternative for polymeric membranes for water filtration. Not only for industrial plants, ceramic membranes are also used for commercial water filtration systems. That being said, let’s look at some benefits of
ceramic membrane filtration:
Service Life: One of the most important reasons for using ceramic membrane water filtration system, is its “service life”. When we compare ceramic membranes to the polymeric membranes, then the former one offers greater service life. The ceramic membranes are made up of intricate and delicate fibers, making them more immune to wear tear or damage. Also, when it comes to warranties, then for water filtration systems with ceramic membranes one can expect double of what the polymeric membranes offer. As water filtration systems are a valuable investment, ceramic membranes can offer a great service if you want to save money when it comes to replacing it after a few years.
Membrane Fouling: Membranes are greatly affected by fouling given that they are not cleaned and maintained on a regular basis. Here, the advantage of using water filtration systems with ceramic membranes is that the rate of membrane fouling is pretty low as compared to the polymeric membranes. Where fouling in polymeric membranes typically starts after 3-4 years, ceramic membranes doesn’t start fouling till 10 years of time period.
Membrane Cleaning and Maintenance: Membrane cleaning generally involves the use of strong cleaning agents and given the type of the membrane you are using, can damage the surface while cleaning is in process. However, ceramic membranes can endure cleaning with strong chemicals and hence, they can be used over polymeric membranes (as the damage is more with polymeric membranes). In addition, ceramic membranes have a lower cleaning frequency when compared to polymeric membranes.
Performance and Durability: Unlike polymeric membranes, ceramic membranes are very much easy to use and hence, can be considered as a more viable alternative when it comes to filtration performance. This would mean that they are more durable and wouldn’t need replacing earlier than necessary.
Flux Rate: In comparison to the polymeric membranes, the flux rate of ceramic membranes is almost double. Less flux rate means you would need less membrane material to filter the same amount of water.
Hence, these were some benefits of ceramic membrane filtration systems. You can choose this membrane filtration system, given that you want to protect your investment for a long-term.
