Ultrafiltration for water treatment
Human health and quality of life depend on the properties and composition of the food and liquids we consume. Unfortunately, the water that comes into our homes through the water pipes is not fit for consumption and is even dangerous for the human body. It needs to be thoroughly treated.
Ultrafiltration of water is a compulsory measure that most consumers have to take. Ultrafiltration makes it possible to fight successfully against impurities in tap water by eliminating all harmful impurities in the water. The production of ultrafiltration membranes has solved the problem of the water's unnatural yellow colour, lack of transparency and sludge content. In this case, progress is helping people to correct their mistakes by providing the opportunity to obtain clean water.
Technological features of the baromembrane separation process
The chemicals contained in the water are usually removed by means of nanofiltration or reverse osmosis. Ultrafiltration removes microorganisms and foreign mechanical impurities from the water.
The use of ultrafiltration membranes improves the quality of tap water, surface water and water from wells. Filtration of water occurs under pressure when it passes through a finely porous membrane with a hole diameter of 0.002-0.1 microns. As a result, all particles larger than its smallest pores remain on the surface of the membrane.
Ultrafiltration is an effective way of purifying water
The high quality of water purification using a sieve mechanism separates the macro-components from the water due to the following factors
- Removal of organic matter residues, clay and colloidal particles of iron, silicon and manganese, which leads to clarification and full water clarity;
- The membrane cuts off viruses, bacteria, Salmonella, Giardia, Escherichia coli, Legionella and other living organisms that are larger than the membrane pores. The capacity of the porous baffle eliminates the need for primary disinfection of the water with chlorine. Mechanical disinfection is sufficient at this stage.
- The ability of ultrafiltration semi-permeable membranes to pass mineral salts, which distinguishes this type of partition from similar models.
Ultrafiltration is an effective modern technology for the water purification, which is in demand among consumers. It avoids most of the problems encountered during the operation of a variety of water supply systems.
The main advantages of ultrafiltration systems
One of the main advantages of ultrafiltration is its efficiency under any conditions, high productivity, regardless of the initial data of the treated liquid. Ultrafiltration membranes are used in domestic and industrial applications.
Ultrafiltration is an energy-saving and economical technology. It is easy to maintain and does not require large quantities of reagents which can be purchased at high costs. The process is automated and easy to use. With this type of membrane, the chemical consumption is reduced by a factor of 10 and the energy costs are halved. At the same time, the overall cost of water treatment will be reduced by 5 times.
Application area of hollow fibre membranes
Plants equipped with hollow fibre membranes are suitable for purification of all types of water. The hollow fibre membrane systems are suitable for purifying all types of water:
- potable water and polluted water;
- surface water and from wells;
- process water used in industry.
Thanks to hollow fibre membranes, treated wastewater can be reused in production plants, reducing the degree of water pollution and the technological impact on the environment.
Sterilizing ultrafiltration is a promising way to purify, disinfect and clarify drinking and natural mineral water that is prepared for bottling.
The quality of the water purification process depends directly on the integrity of the membrane fibres. It can be damaged by constant mechanical, biological and chemical influences. Plant failures that occur are most often due to the accumulation of coarse particles. In order to prevent clogging of the unit and to prolong its service life, it is recommended to use a special pre-filter, which should be placed directly in front of the membrane.
The use of a modern ultrafine water purification system gives a hundred percent result. The water is absolutely safe for humans and animals. Technical devices cannot be blocked. The ultrafiltration water purification method is considered one of the most promising, reliable and in-demand methods.
