RO reverse osmosis deionized water equipment is an important device that uses reverse osmosis technology for purifying and separating water sources. The performance of RO membranes has a significant impact on the quality of water treatment. Therefore, it is recommended to purchase membranes from reputable manufacturers with guaranteed quality. In addition, regular cleaning of the reverse osmosis membrane is required during operation and use. So what are the common pollutants in RO membranes? Below are a few points summarized by Quante Xiao Bian for reference:
1. Calcium carbonate scale: When the pH value is high, calcium carbonate will accumulate on the RO membrane. If not cleaned in time, it will damage the membrane surface. Therefore, after calcium carbonate deposition occurs, the pH value of water should be reduced in time, and continuous operation for one or two hours should be done for flushing and cleaning. If the deposition time is long, citric acid cleaning solution should be used for circulating cleaning or overnight soaking to remove it.
2. Silica scale: Special cleaning methods and chemical solvents are required to remove the silica in soluble form deposited on the RO membrane. To avoid damage to the membrane surface, it is recommended to find a professional RO membrane manufacturer for cleaning. In addition, higher flushing flow rate should be used during cleaning, and repeated circulation and soaking are required.
3. Organic deposits: If organic deposits cause contamination of the RO membrane, common ones include microbial slime and mildew. In this case, professional cleaning liquid can be used to remove it. In order to prevent the organic material from multiplying on the RO membrane, a suitable solution can be circulated and soaked in the system. However, it should be noted that effective cleaning usually requires a longer soaking time. Moreover, if the RO system is not used for more than 7 days, suitable cleaning agent should be used to clean the RO membrane system.
These are several common RO membrane pollutants. Different methods should be adopted to remove different pollutants. Some pollutants are difficult to identify and clean. If you are uncertain about the equipment contamination situation, it is recommended to find a professional RO membrane manufacturer or engineering company to provide cleaning services. This could improve the efficiency of pollutant cleaning.
