Reverse osmosis technology is widely used in all walks of life, which is conducive to the continuous and stable water supply of the water production system. In addition, it is also necessary to monitor daily operation data, record operation data, and sample testing. Through good prevention and maintenance In order to better meet the water quality requirements of enterprises.
The application of reverse osmosis technology in purified water equipment often needs to consider the following issues:
One is the selection of the original water pump. If the raw water pump is not matched, it is easy to cause insufficient water production in the pretreatment system, which cannot meet the water inflow requirements of the subsequent RO;
The second is the replacement of some consumables in the pretreatment unit, such as quartz sand, activated carbon, and exchange resin. Since these consumables are used for a long time, the adsorption and replacement of impurities will be greatly reduced. Therefore, they need to be cleaned and replaced regularly according to the actual production situation;
The third is the effect of temperature on the water produced by the reverse osmosis membrane. Usually, the inlet water temperature before the RO membrane is controlled between 20-25 °C to ensure the high-efficiency operation of the RO membrane and improve the desalination rate.
The fourth is the cleaning and disinfection of reverse osmosis membranes. The reverse osmosis membrane will be fouled and blocked after long-term use, and the water permeability will be significantly reduced. Therefore, the RO membrane module can be chemically cleaned by the reverse osmosis cleaning device to remove the dirt. Water disinfection. In addition, if the conductivity and water production of the system meet the design standards and corrective measures are required, after cleaning or replacing the reverse osmosis system, a risk assessment should be done to determine whether the system needs to be verified according to the actual situation.
