Reverse osmosis is a process that relies on selective permeation(Half-through)Membrane separation technology in which the working force of the membrane can be driven by pressure,When the pressure applied in the system is greater than the osmotic pressure of the feed water solution,Water molecules constantly pass through the membrane,It flows through the product water channel into the pipe,Then impurities in the water flow out from one end,Such as ions, organic substances, viruses, etc,It is retained on the water inlet side of the membrane,Then it flows out from the concentrated water outlet,So as to achieve the purpose of separation and purification.

　　Reverse osmosis equipment can block all dissolved salts and those with molecular weights greater than100Organic matter,But water molecules are allowed to pass through,The desalination rate of reverse osmosis composite membranes is generally greater than98%,They are widely used in the preparation of industrial pure water and electronic ultrapure water,Production of drinking purified water,Processes such as boiler feed water,The use of reverse osmosis equipment before ion exchange can significantly reduce the amount of operating water and wastewater discharged. In the following text, let's talk about the specific process flow of reverse osmosis equipment:

　　The total hardness of the influent water quality is required≤500PPM,The maximum operating temperature shall not exceed45℃,Continuous motionPHScope2     Desalination rate of effluent quality>99%,The electrical conductivity of the water quality is lower than10us/cmAs follows;

　　The equipment can be divided into fully automatic and semi-automatic types. It is convenient to operate and does not require manual operation during continuous normal operation.

　　The common process flows of reverse osmosis equipment include:Sand filter→Carbon filter→Softening→Reverse osmosis host;Sand filter→Carbon filter→Reverse osmosis host

　　This device is easy to operate,The effluent quality is stable.;The water output of the equipment is designed according to the customer's requirements,The process of the equipment is improved accordingly based on the local water quality conditions,The selection of equipment materials can also be adjusted accordingly according to your needs.

　　The following several questions often arise during the use of the equipment:

　　The conductivity of the effluent water quality has increased:The condition of the equipment at each period needs to be recorded in a timely manner,If the electrical conductivity is rising slowly,It is a normal phenomenon that the desalination rate is gradually decreasing,Just carry out corresponding maintenance in a timely manner according to the reasons for the increase in its electrical conductivity;If the conductance suddenly rises,It depends on whether the filter components are damaged, the quality of the raw water has changed significantly, or the failure of some pretreatment materials, etc.

　　After the reverse osmosis membrane is cleaned,The water quality has not changed much.:aCheck if the components are damagedbWhether a certain pre-treated material has failedcDuring the membrane washing process, it was not clear which species contaminated the membrane elements and the extent of the contamination,And treat the symptoms accordingly.

　　The system pressure difference is too large:According to different membrane elements,The pressure difference of the system should be controlled within a reasonable range,To avoid causing damage to the membrane elements.

　　The utilization rate of raw water is not high,The concentrated water discharge is too large:Whether the influent flow rate is sufficient, whether the pressure meets the working conditions of the material, and whether the equipment design is reasonable, etc.
