Product Description
Product Description
Brief description of reverse osmosis pure water equipment: application scope of reverse osmosis pure water treatment>Preparation of pure water and ultrapure water in electronics, industry, medicine, food and other industries; purification and preparation of water for textiles and chemical industries; water for food and beverages, wine Purification and preparation of process water; useful substances and concentration and recovery of aqueous solutions in industrial production; pre-desalination treatment of high-pressure boiler feed water in power plants and other enterprises; desalination and desalination of brackish water and seawater; purified water device as the first level of high-purity water production Desalting equipment.
Water quality requirements for reverse osmosis equipment:
High inlet water SDI (15 minutes) <5
High influent turbidity＜1.0NTU
High free chlorine concentration of influent <0.1ppm
High inlet water temperature＜45℃
High Fe content in influent water <0.05ppm
Raw water tank
Function: Overcome the instability of the water supply of the pipe network and ensure the stable and continuous water supply of the entire system; at the same time, it also provides a guarantee for the long-term reliability of the equipment.
Selection: PE material or stainless steel water tank.
Control: The water tank is equipped with a high-water level float valve and a low-water level switch. It has the advantages of high reliability, low price, simple structure and convenient installation. When the water level is at a high level, the float valve is closed to stop water inflow. When the water level is at a low water level, the high water level float valve opens and starts to fill the water tank. At the same time, the low water level switch is turned off and the booster pump stops working.
Booster pump
Function: Provide necessary working pressure for pretreatment equipment.
Selection: Determine the working pressure of the booster pump according to the design pressure drop of each pretreatment device (the maximum pressure drop of each filter device is 0.05Mpa), and the pressure before the high-pressure pump cannot be less than 0.5Kg/cm2.
Control: Use a regulating valve after the pump to adjust the pressure and water intake.
Mechanical filter
Function: The raw water first passes through a mechanical filter, and 12-24 mesh fine quartz sand is placed in the filter, so that the flocs, rust and other suspended impurities in the raw water are intercepted in the process. Since the mechanical filter retains a large amount of suspended impurities during operation, in order to ensure the normal operation of the filter, the filter must be flushed and backwashed regularly.
Selection: Use FRP material (glass reinforced plastic) container.
Control: The backwash operation of the mechanical filter adopts a manual controller. The filter should be cleaned once a day, and the cleaning time is 10-20 minutes.
Activated carbon filter
Function: This process adopts activated carbon filter, which is very important as the pretreatment of reverse osmosis device. The reverse osmosis system requires the inlet water index SDI≤5, and the residual chlorine <0.1mg/L. In order to meet its water intake requirements, the raw water needs to be further purified to achieve the reverse osmosis water intake index. A carbon filter is installed in front of the reverse osmosis device, which has two main functions: 1. It absorbs some organics in the water with an adsorption rate of about 60%; 2. It absorbs residual chlorine in the water. It absorbs inorganic colloids, organic colloids and soluble organic polymer impurities with a particle size of about 10-20 angstroms, as well as residual chlorine that is difficult to remove in a sand filter. The reason why activated carbon can be used to adsorb active materials with a particle size of about tens of angstroms is that its structure has a large number of micropores and gaps with an average pore diameter of 20-50 angstroms. This structural feature of activated carbon makes its surface adsorption The area can reach 500-2000m2/g, because the molecular diameter of general organic matter is slightly less than 20-50 angstroms, so activated carbon has a strong adsorption effect on organic matter. In addition, activated carbon has a strong dechlorination ability. Because the residual chlorine has strong oxidizing properties, the residual chlorine reacts with carbon to generate carbon dioxide and -1 valent chloride ions, so only a small amount of carbon is lost, so the activated carbon is dechlorinated It can be used for a long time. Activated carbon not only has the above functions, but also can remove the peculiar smell and pigment in the water, and improve the clarity of water. After the activated carbon is used for a period of time, its adsorption capacity decreases and needs to be regenerated or replaced. Therefore, after the raw water passes through the carbon filter, the water quality can be greatly improved, and the pollution of the reverse osmosis membrane can be reduced. After the treatment, the water quality can meet the water quality requirements of the reverse osmosis device (residual chlorine <0.1mg/L).
