Difference between ultrafiltration and reverse osmosis

Reverse osmosis equipment and ultrafiltration equipment are two different types of water purification equipment, which have significant differences in filtration precision, working principle, applicable water quality and water purification effect.

1. Filtration precision: the filtration precision of reverse osmosis membrane is generally below 0.001um, while the filtration precision of ultrafiltration membrane is generally between 0.005-1um. Therefore, the reverse osmosis equipment can filter out the finer impurities and ions, and produce purer water.
2. Working principle: reverse osmosis equipment using reverse osmosis technology, through the semi-permeable membrane filtration, the water ions, microorganisms, organic matter and other dissolved substances filtered out, so as to achieve the purpose of water purification. And ultrafiltration equipment through physical filtration, the water impurities, particles, suspended solids and other substances filtered out.
3. Applicable water quality: ultrafiltration system is suitable for water quality is relatively clean areas, such as tap water. In the poor water quality, containing more impurities, microorganisms and other areas, you need to use reverse osmosis system.
4. Water purification effect: the reverse osmosis system of water purification effect is relatively good, can achieve a high rate of water purification, purified water is more pure than ultrafiltration. However, the reverse osmosis cartridge is more complex, requiring higher maintenance costs, while ultrafiltration is relatively simple and easy to maintain.

Ultrafiltration membrane cleaning method

Physical cleaning method and chemical cleaning method, physical cleaning method according to the direction of the rinse can also be divided into different reverse rinse, backwash, positive wash rinse three. Which cleaning method, this is mainly for different levels of pollution selection, pollution is more serious using chemical cleaning method, general pollution can be used in the case of physical cleaning method.

Ultrafiltration membrane cleaning method:

Ultrafiltration membrane will be used with the prolongation of time, ultrafiltration membrane pollution will continue to increase, when the pollution reaches a level when the ultrafiltration membrane needs to be cleaned, cleaned to allow the ultrafiltration membrane to maximise the recovery of the original water yield, then the ultrafiltration membrane cleaning methods there are several? Ultrafiltration membrane cleaning methods can be divided into two categories are: physical cleaning methods and chemical cleaning methods. Physical cleaning methods can also be divided into reverse flushing, backwashing, washing and rinsing three. These cleaning have different work and characteristics, the following is a detailed introduction.

1. Physical cleaning method:The physical method is actually to use water with a certain pressure to rinse the ultrafiltration membrane, which is also the most commonly used method. Because of the direction of this water flushing, not the same, and can be divided into reverse flushing, backwashing and positive washing flushing.
2. Reverse flushing: use raw water to flush the impurities in the membrane and the water inlet end face.
3. Backwashing: Use ultrafiltration water to flush the pollutants from the surface of the membrane block to loosen and flake off, and discharge them from the inlet and concentration port respectively (acid, alkali or sodium hypochlorite can be added to strengthen the cleaning effect of the drugs).
4. Rinse: use raw water to flush the impurities in the membrane and the end surface, and clean the ultrafiltration membrane according to the operation status.
