Ultrafiltration is a separation process using a membrane with small pores (0.001 to 0.1 µm) to filter out solid particles and large molecules from a liquid. It effectively removes fine particles such as silica, silt, endotoxins, plastics, proteins, smog, and viruses.

Nanofiltration membrane technology removes dissolved contaminants from water, including pesticides, herbicides, and pharmaceuticals. It also effectively eliminates viruses, bacteria, and other pathogens, making it essential for ensuring safe drinking water.
