Microfiltration Compared with Alternative Filtering Systems
In today’s regulatory climate, it is important for potential buyers to understand the differences between the various types of filtration systems. Microfiltration, just like all of the other systems, has a specific set of scenarios that stand as the best option. Understanding the differences between different types of water and wastewater treatment equipment is an excellent way to help make the best investment, for purposes of safety, quality and financial returns.
Explaining Water Filtration
The majority of modern filtration systems have a number of things in common, the most important of which is the use of a membrane. Such a membrane can exist in many forms, but all forms consist of a plastic or polymer material perforated with a large number of extremely small pores. These pores are large enough to allow water through, and yet small enough to halt the flow of foreign materials. The main difference between microfiltration and the other types, then, is the size of these pores, and thus the types of materials it is best suited to remove. The other common factor is the use of pressure to push contaminated water through the membrane into a chamber that consists of purified water.
Alternatives to Microfiltration
The most widely used alternatives to microfiltration are considered to be reverse osmosis, ultrafiltration and nanofiltration. The primary difference between these processes is the size of the pores in the membrane, which means that each type is best suited to filtering different kinds of materials. For a quick explanation: Microfiltration is well-suited to trap bacteria; ultrafiltration is great for removing some viruses as well as other biomaterials such as proteins; and ultrafiltration and reverse osmosis are strong choices for the deep removal of viruses, chemicals, saline, and other tiny particles.
Relative Benefits of Microfiltration
While a purchaser’s choice depends greatly on what type of material needs to be filtered, there are other factors to consider. Generally speaking, microfiltration requires very little maintenance or chemical assistance.
Overall, the decision to use any of these types of filtration systems depends on an analysis of business needs and pragmatic concerns. Feel free to contact M.W. Watermark with any questions.
