What should be noted when large pharmaceutical water purification equipment to run the article:? Application of large pharmaceutical water purification equipment is very extensive, and now the poor condition of the water environment, the emergence of large pharmaceutical water purification equipment for people to solve the problems of large pharmaceutical purified water The most important thing for equipment to run normally for a long time is maintenance. Careful equipment maintenance makes the equipment handy. Therefore, care should be taken not to damage the machine during the operation of the pure water equipment. The operation precautions of large-scale pharmaceutical purified water equipment must be mastered by the operator. Accurate operation and correct maintenance are the guarantee for the long-term stable operation of large-scale pharmaceutical purified water equipment. Next, I will take you to understand the large-scale pharmaceutical purified water accurately. Some precautions in the use of equipment. 1. Prevent the filter material from entering the reverse osmosis device: select the appropriate filter water outlet device to prevent the filter from leaking sand and activated carbon, and select the appropriate activated carbon to prevent de-powdering during use. 2. It is best to set up an independent water supply system for large-scale pure water equipment that uses tap water as the water source. This can ensure the stable operation of the water supply system and reduce the instantaneous impact on the water supply network of the whole plant when the RO system starts and stops. When the RO device draws water directly from the raw water pipe network, high and low pressure protection facilities should be installed, because most of the tap water pipe network pressure fluctuates greatly. 3. The compatibility between the medicament and the medicament should be considered first, and the compatibility between the medicament and the membrane material should be considered secondly. For example, coagulants, coagulants, bactericides, reducing agents and scale inhibitors are often used in RO systems at the same time. Since colloids in natural water are generally negatively charged, positively charged cationic coagulants are usually used. In order to prevent scaling of the RO device, almost all measures of adding scale inhibitors are considered at the water inlet of the RO, and these scale inhibitors are almost all negatively charged. Therefore, the cationic coagulant should be avoided to react with anionic scale inhibitors to prevent the colloidal compounds generated by the reaction from depositing on the membrane surface. 4. The water permeability of the membrane increases with the increase of water temperature, but high temperature will accelerate the hydrolysis rate of the membrane, and make the organic membrane softer and easier to compact. Therefore, for organic membranes, it is generally appropriate to control the temperature within the range of about 20-30°C. 5. In order for reverse osmosis to proceed, the applied pressure must make the pressure difference between the two sides of the membrane greater than the osmotic pressure difference. The choice of operating pressure depends on the concentration of the original solution, because it is related to the osmotic pressure difference. In addition, it also depends on the water permeability of the membrane and the water recovery rate. Generally speaking, increasing the operating pressure will increase the water production, but if the pressure is too high, the membrane will be compacted and the water permeation will decrease. 6. In order to avoid blocking the reverse osmosis device, the raw water should be pretreated to eliminate suspended solids in the water and reduce the turbidity of the water; in addition, it should be sterilized to prevent microorganisms from growing in the device. The above are the most important issues in the process of using large-scale pharmaceutical purified water equipment. With the maintenance of large-scale pharmaceutical purified water equipment, the system can always be operated in an optimal state to ensure the stability of the water supply.
