Are the membrane elements of small and medium-sized reverse osmosis pure water treatment equipment polluted?
Are the membrane elements of small and medium-sized reverse osmosis pure water treatment equipment polluted? Author of the article: the rapid development of industrial development makes more and more serious water pollution, and even has affected the quality of our water. Small and medium-sized reverse osmosis pure water treatment equipment can purify water quality and are favored by the majority of industries. In fact, many people do not understand how small and medium-sized reverse osmosis pure water treatment equipment purifies water. Today, I will popularize it for everyone. The pretreatment system in the small and medium-sized reverse osmosis pure water treatment equipment mainly consists of a quartz sand filter device, an activated carbon filter device, and a precision filter device. The purpose is to remove sediment, rust, colloidal substances, suspended matter, pigments, and odors in the raw water. , Biochemical organic matter, reduce the residual ammonia value of the water and pesticide pollution and other harmful substances. The mechanical filter in the small and medium-sized reverse osmosis pure water treatment equipment is mainly used to reduce the turbidity of the water. It can be used as a pretreatment equipment or as an ordinary filtration equipment alone, and is mainly used in areas with low water quality requirements. Small and medium-sized reverse osmosis pure water treatment equipment uses the adsorption performance of activated carbon to remove harmful substances in the water, such as organic matter, colloids, microorganisms, oils, residual chlorine, and odors, which are adsorbed on the surface of activated carbon. Small and medium-sized reverse osmosis pure water treatment equipment integrates pretreatment system, RO system, EDI system, and post-treatment system. It is easy to operate and maintain. The pollution of membrane elements of industrial pure water equipment still occurs frequently, what about industrial pure water equipment membrane What is the cause of the contamination of the components? 1. The unreasonable operation and use of the operation management personnel (pressure difference, water production, recovery rate, concentrated water volume, cleaning and other). 2. Inappropriate equipment is selected, or the material is incorrectly selected (pumps, piping, and others). 3. The composition of the raw water has changed greatly or the characteristics of the water source have undergone a fundamental change. 4. The system chemicals injected into reverse osmosis pure water equipment fails (acid, scale inhibitor/dispersant, flocculation/coagulant aid, reducing agent and others). 5. Long-term accumulation of insoluble sediments in the membrane system. 6. A considerable degree of microbial contamination has occurred in the reverse osmosis membrane system. 7. Appropriate protective measures have not been taken after the small and medium-sized reverse osmosis pure water treatment equipment operates intermittently or the system is out of use. 8. Inappropriate pretreatment system equipped with pretreatment device is not suitable for the raw water quality and flow rate, or the system is not equipped with necessary process devices and process links; or the pretreatment device is not operating normally, that is, the original pretreatment of the system The equipment has low ability to remove raw water SDI components, turbidity, jelly, etc., and the pretreatment effect is not ideal. The above is an introduction to the reasons for the pollution of the membrane elements of the small and medium-sized reverse osmosis pure water treatment equipment. The pollution of the membrane elements will affect the operation of the small and medium-sized reverse osmosis pure water treatment equipment and affect the quality of the produced water.
