Understanding the Core Water Purifier Technologies

Microfiltration (MF)

It operates based on a simple yet effective principle.

Using a porous membrane with relatively large pores, typically in the range of 0.1 – 50 micrometers, MF acts as a physical barrier.

When water passes through this membrane, it can effectively remove large – sized particles.

For example, sand, silt, and rust particles that are visible to the naked eye or are relatively large in the water are trapped by the membrane.

This makes the water visually clearer.

However, it’s important to note that MF has its limitations.

It cannot eliminate smaller contaminants such as bacteria, viruses, and most chemical pollutants.

These substances are small enough to pass through the relatively large pores of the microfiltration membrane.

Ultrafiltration (UF)

It functions by utilizing a pressure difference across a semi – permeable membrane. The pores of an ultrafiltration membrane are much smaller than those of a microfiltration membrane, typically ranging from 0.001 – 0.1 micrometers. This allows it to filter out a wide range of harmful substances. UF can effectively remove not only suspended solids like sand, rust, and colloids but also bacteria, protozoa, and some large – molecule organic pollutants. For instance, common bacteria such as Escherichia coli and Salmonella, which can cause various diseases if ingested, are retained by the ultrafiltration membrane.

Minerals like calcium, magnesium, and potassium, which are essential for the human body, are small enough to pass through the membrane’s pores along with water molecules.
