How To Maintain RO Membrane In Daily Life?
Jan 31, 2024
Water RO Membrane is an efficient membrane separation technology that can effectively remove dissolved salts, organic matter, microorganisms and other impurities in water to obtain high-quality water. In daily life, reverse osmosis membranes are widely used, such as household water purifiers, seawater desalination equipment, etc. In order to ensure the normal operation and service life of the reverse osmosis membrane, it needs to be properly maintained.
1. Regular cleaning
During the use of the reverse osmosis membrane, it will be contaminated by impurities in the water, leading to problems such as a decrease in Membrane Flux and a decrease in Salt rejection rate. Therefore, the RO membrane needs to be cleaned regularly to remove dirt and impurities on the membrane surface. Cleaning methods can use two methods: physical cleaning and chemical cleaning.
2. Prevent membrane clogging
During use, the reverse osmosis membrane may be clogged by impurities such as suspended solids and colloids in the water, resulting in a decrease in membrane flux. In order to prevent membrane clogging, pre-treatment equipment, such as filters, activated carbon filters, etc., can be installed before the water enters to remove suspended solids and colloids in the water.
3. Control incoming water quality
The reverse osmosis membrane has certain requirements for the incoming water quality. If the incoming water quality does not meet the requirements, it will lead to membrane fouling, membrane flux reduction and other problems. Therefore, it is necessary to control the quality of the incoming water to ensure that the turbidity, SDI value, COD, TOC and other indicators of the incoming water are within the specified range.
4. Replace the filter element regularly
Some filters are usually installed in front of the reverse osmosis membrane to remove large particles and impurities from the water. After being used for a period of time, these filters will become ineffective due to clogging and need to be replaced regularly.
5. Pay attention to the preservation of membranes
When the RO membrane is not in use, it needs to be stored correctly to prevent the membrane from being contaminated and damaged. There are two methods of preservation: wet preservation and dry preservation.
In short, RO membrane is a very important membrane separation technology and is widely used in daily life. In order to ensure the normal operation and ro membrane service life of the reverse osmosis membrane, it needs to be properly maintained. Through regular cleaning, preventing membrane clogging, controlling incoming water quality, regularly replacing filter elements and paying attention to membrane preservation, the service life of the reverse osmosis membrane can be effectively extended and the separation efficiency of the membrane and the quality of produced water can be improved.
