membránfiltrációval

Membránfiltrációval is a Hungarian term referring to membrane filtration. Membrane filtration is a separation process that uses semipermeable membranes to remove impurities from liquids or gases. The membranes act as physical barriers, allowing smaller molecules or particles to pass through while retaining larger ones.

Different types of membrane filtration exist, categorized by pore size and the pressure applied. These include microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Microfiltration removes suspended solids and bacteria. Ultrafiltration removes larger molecules like proteins and viruses. Nanofiltration removes divalent ions and some organic molecules. Reverse osmosis is the finest form, capable of removing dissolved salts and small molecules.

The applications of membrane filtration are widespread. It is commonly used in water purification for drinking water and industrial processes, desalination of seawater, and wastewater treatment. In the food and beverage industry, it is employed for clarifying juices, concentrating milk, and producing beer. It also finds use in the pharmaceutical and biotechnology sectors for sterile filtration and purification of drug substances. The choice of membrane and operating conditions depends on the specific separation task, the nature of the feed stream, and the desired purity of the permeate.
