What details should be paid attention to during operation of small and medium seawater desalination equipment? Author: countries are now encouraging the development of seawater desalination, in fresh water resources increasingly scarce today, desalination has become an important way to get fresh water resources, desalination industry will enter a rapid development period. With the maturity of my country's desalination technology, under the background of national policy support, my country's desalination industry is expected to enter a period of rapid growth. Small and medium-sized desalination equipment can desalinize seawater, so that people can get fresh water resources that can be used. When small and medium-sized desalination equipment is in operation, we all wish to forget that the equipment does not malfunction and can operate stably, so it needs to be in use. Pay attention to some details, so what details should be paid attention to when small and medium-sized desalination equipment is in operation? 1. SDI index needs to be tested regularly. Too high SDI will cause irreversible pollution of the membrane module and shorten the service life of the membrane module. 2. The recovery rate needs to be controlled. If the recovery rate is too high, it is easy to cause the insoluble salt components to exceed the solubility product and fouling. In addition, the concentrated water flow rate in the component will be too low, which is easy to produce concentration polarization and cause fouling. At the same time, it is not conducive to colloid in the water. , Suspended solids, etc. are discharged. 3. Pay attention to the pressure difference of the membrane module. Generally, the initial pressure difference of the membrane module is very small. If the pressure difference increases quickly, it indicates that the membrane module is contaminated or fouled. The cause needs to be found immediately and corrected. 4. It is necessary to pay attention to the changes in water production and desalination rate, which usually occur at the same time as the pressure difference changes. In a short period of time, the water production and desalination rate have changed significantly. Immediately check whether the pretreatment system of the small and medium-sized seawater desalination equipment is operating normally, such as whether the dosage is appropriate, whether the filter is leaking, etc. This is the end of the introduction about what matters to pay attention to when small and medium-sized seawater desalination equipment is in operation. I hope it will be helpful to everyone. When using these details, not only can the equipment operate stably, but also can extend the small and medium-sized seawater desalination equipment. Life.
