Ultrafiltration

Ultrafiltration is the process of filtering liquid through a semi-permeable membrane under pressure. In ultrafiltration, water molecules and small particles pass through the membrane, while large molecules and particles are retained.

Ultrafiltration is widely used in water purification, food concentration, wastewater treatment, medicine and other applications.

One example of ultrafiltration in the human body is the work of the kidneys. In the kidneys, ultrafiltration of blood occurs through the glomeruli, as a result of which excess water, urea, salts and other metabolic products that are currently unnecessary are removed from the blood. These substances are excreted from the body in the urine. Thus, ultrafiltration in the kidneys allows you to maintain water-salt balance and cleanse the blood.

Ultrafiltration is a pressure filtration process used to remove impurities from liquids and gases. This process is widely used in medicine, industry and scientific research.

One example of the use of ultrafiltration is the filtration of blood in the kidneys. In the kidneys, the blood passes through a filter that removes excess water, urea, and other metabolic products from the blood. This helps maintain normal kidney function and prevent the formation of kidney stones.

Ultrafiltration is also used in industry to remove contaminants from water and other liquids. For example, in beer production, ultrafiltration is used to remove yeast and other microorganisms from the wort.

In science, ultrafiltration is used to separate mixtures of different substances into their components. For example, ultrafiltration can be used to separate proteins and lipids in blood serum.

Thus, ultrafiltration is an important process in various fields, from medicine to industry. It allows you to purify liquids and gases from impurities and obtain cleaner products.

Ultrafiltration Ultrafiltration is a method of filtering substances under pressure and is used in various fields such as medicine, science and technology. Today, ultrafiltration is one of the most effective technologies for purifying liquids in the pharmaceutical, food industry and water treatment. What is ultrafiltration?

The ultrafiltration method is pressure filtration, where the process of separating liquid and solid occurs through selective diffusion between two phases - liquid and gas, or between heterophase and homogeneous. The difference between an ultrafiltration system and a conventional filter system is the smaller overall dimensions of the membranes and the volume and filtration area. All this provides greater productivity in small ranges of separation efficiency and high selectivity when separating molecules and ions of similar molecular weight and size - a practically non-selective ultrafilter system.

Ultrafiltration processes and devices are used in two main methods: 1. Ultrafiltration concentration. In this method, the main goal is to remove more water to obtain a less soluble product. 2. In-depth isolation is the process of obtaining the target product directly with a low content of impurities by isolating it from products that have a low concentration or similar chemical composition.

Application of ultrafiltration in chemistry It is used in the following industries: - oil and gas; - mining; - food; - chemical; - medical; - cosmetic; - metallurgical. Enrichment of petroleum products It is distinguished by the fact that it has an ultra-high membrane pore size - up to 0.003-0.1 nm. This method
