What are the precautions and troubleshooting methods for stainless steel purified water treatment equipment? Author: As the industry production strict water quality requirements, stainless steel water purification equipment utilization rate is more common, for new users, the beginning of purified water treatment equipment, stainless steel, and certainly do not understand the use and operation and many more. The first is to control the pressure when the water enters. This is also the most important point of all conditions. If the pressure is too high, the device will issue an alarm to the operator. This is what we need to monitor with the most equipment to avoid damage to the pressure transmitter. The second is to always pay attention to the change of water temperature, so that it is easy to find inconsistencies with the specified temperature range of the equipment, thereby ensuring the normal operation of the equipment. The last thing is to pay attention to the concentrated water flow monitoring system, so as to achieve the purpose of monitoring the flow of the concentrate and controlling the smooth operation of the equipment. Stainless steel purified water treatment equipment uses membrane technology to purify water through RO membrane filtration and separation. Recently, many people have checked the Internet for these situations in the process of using the equipment. The following editor will sort out for everyone: 1. Production The water volume cannot meet the production: some have been cleaned and maintained, but the water production volume still cannot meet the requirements, so the membrane needs to be replaced. 2. The quality of the produced water cannot meet the production requirements: some have been cleaned and maintained, but the quality of the produced water is still not good, so the membrane needs to be replaced. For example, the ultrapure water production process requires the conductivity of the produced water to be lower than 10 us/cm. Once the water conductivity approaches 10, if it cannot be lowered through maintenance, the membrane must be replaced. 3. The production process cannot meet the operating requirements: For example, the conductivity of the reverse osmosis product is too high, which causes frequent regeneration of the mixed bed. Although it can meet the production, the operation becomes frequent, so the membrane needs to be replaced. 4. Membrane element damage: the membrane breaks due to the telescope effect, and its performance is greatly reduced after being oxidized, so it needs to be replaced. 5. Generally, the RO membrane is replaced once a year under normal use of standard urban tap water. (TDS value of raw water—TDS value of pure water) ÷ TDS value of raw water×100%≥75%. If the obtained value is ≥75%, it proves that the water quality is qualified and the RO membrane can be used continuously. If the obtained value is less than 75%, the RO membrane must be replaced.
