1R.O Pure Water Treatment MachineInlet water quality requirements:

To ensure the safe and normal operation of the reverse osmosis water treatment system and improve the core components—The service life of reverse osmosis membranesreverse osmosis membraneTo enhance performance, appropriate pre-treatment and adjustment should be carried out on the raw water entering the reverse osmosis equipment to achieve the following indicators:

2. The Influence of Inlet Water Quality on the Performance of Reverse Osmosis Membrane

（1）In the table aboveSDIValue refers to the pollution density index of water. Its numerical value reflects the content of suspended colloidal substances in water. The presence of these substances can easily clog the reverse osmosis membrane, leading to a decrease in the water production rate and desalination rate of the device.

（2）PHThe control of values and Langmuir index is mainly to preventCaCO3After precipitation on the membrane surface, scale forms, blocking the reverse osmosis membrane.

（3）In addition to having a significant impact on the permeability of the membrane, an increase in water temperature can also enhance the solubility of silicon. In the case of high silicon content in water, increasing the water temperature is beneficial for improving the recovery rate of product water, but excessively high water temperature can accelerate the membrane pressure density.

（4）When the content of metal oxides such as iron, manganese, and aluminum is high, hydroxide colloids are easily formed on the surface of the film, resulting in deposition phenomena. Therefore, iron, manganese, aluminum, etc. should be removed in the pretreatment process to achieve the specified indicators.

（5）If the incoming water contains a large amount of sulfate ions, it is easy to produce calcium sulfate（CaSO4）Precipitation, the solubility product of calcium sulfate should be calculated, and its solubility product varies with ion strength. For reverse osmosis systems, due to the concentration product being19×10-5Above, calcium sulfate precipitation will form on the surface of the membrane.

II1T/h reverse osmosis equipment,R.O Pure Water Treatment Machine,Function Description of Fully Automatic Water Treatment System:

The pre-treatment system for reverse osmosis includes a raw water pump, mechanical filter, activated carbon filter, security filter, high-pressure pump, and reverse osmosis pure water machine.

1. Raw water pump: In the pre-treatment process, there are requirements for the inlet water pressure, and the raw water pump plays a role in boosting and improving the raw water.

2. Quartz sand filters and activated carbon filters effectively remove low molecular weight organic matter and free chlorine from water, as well as reduce odors, color, and odor in water. As a reverse osmosis andion-exchange systemThe pre-treatment device of the activated carbon filter can effectively prevent organic pollution on the surface of reverse osmosis and ion exchange resin, without being affected by its own inlet water temperaturePHThe influence of values and organic mixtures. It can effectively remove low molecular weight organic compounds and free chlorine from water, and also effectively prevent reverse osmosis andion exchange resinSurface organic pollution. It has a uniform water distribution method to achieve effective filtration and can meet the long-term requirements of reverse osmosis membrane for organic pollution control. Equipped with a backwashing device, it has strong backwashing ability, short time, and low water consumption.

3. Security filters,Security filterThe function of intercepting raw water is greater than5uTo prevent particles from entering the reverse osmosis system, these particles may penetrate the reverse osmosis membrane components and scratch the impeller of the high-pressure pump after being accelerated by the high-pressure pump. The filter element in the filter is a replaceable filter element. When the pressure difference between the inlet and outlet of the filter is greater than the set value (usually0.07-0.1MPa）At that time, it should be replaced. The security filter adopts corrosion-resistant material304Stainless steel shell material. The filter element is made of polypropylene by spray melting, and its characteristics are: the hole shape is conical structure, which can filter deep and form deep filtration. It has a large capacity for dirt absorption and a long service life (can be maintained)2-3Months), easy to replace.

4. High pressure pumps, based on the characteristics of reverse osmosis itself, require driving force to overcome resistance such as osmotic pressure in order to ensure the designed water production rate.high-pressure pumpThe function is to provide sufficient inlet pressure for the reverse osmosis device and ensure the normal operation of the reverse osmosis membrane. According to the configuration of reverse osmosis, after calculation by specialized software, the design temperature is20℃, the required inlet pressure should not be less than1.3MpaStainless steel high-pressure pump. This system uses an imported vertical high-pressure pump, which has the characteristics of small footprint, high efficiency, low noise, low maintenance time, and energy saving.

5. The reverse osmosis device is the main desalination device in this system. The reverse osmosis system utilizes the characteristics of the reverse osmosis membrane to remove the majority of soluble salts, colloids, organic matter, and microorganisms from water. After pre-treatment, qualified raw water enters and is placed inpressurecontainerThe membrane components inside, including water molecules and a small amount of low molecular weight organic matter, pass through the membrane layer and are collected through a collection pipeline before being directed to the production water pipe and injected into the reverse osmosis water tank. A series of control valves, monitoring instruments, and programmable operating systems are installed on the inlet, production, and concentrated water pipelines of the system, which will ensure the systematic operation of the equipment with long-term quality and quantity assurance. The reverse osmosis membrane components of this device all use the world's advanced ultra-low pressure composite membrane, which achieves a desalination rate of98%.

6. The regulating valve in front of the pump can be opened slowly and closed slowly to prevent the back pressure formed by the instantaneous shutdown of the high-pressure pump.

7. The inlet regulating valve, installed after the pump, is mainly used for regulating and controllingROThe membrane inlet water volume is used in conjunction with the concentrated water regulating valve to adjust the pressure and water volume inside the membrane tube.

8. Conductivity meter

9. Concentrated water solenoid valve, using solenoid valve, has stable operating performance. Its function is to open this valve during fast flushing, so thatROThe flow rate inside the membrane accelerates, taking away the dirt on the membrane surface.

10. The pre filter and post filter pressure gauges of the security filter mainly display the pressure situation of the raw water before entering the pump. By observing these two gauges together, it can determine whether the security filter element has failed or whether it needs to be cleaned. When the pressure difference is significant (approximately)0.05Mpa）This indicates that the filter element should be cleaned. If the condition still does not meet the requirements after washing, it should be replaced.

11. High pressure pump and concentrated water pressure gauge,The pressure gauge after the high-pressure pump displays the pressure when water enters the membrane, and the concentrated water pressure gauge displays the pressure from the outlet to the concentrated water regulating valve. When adjusting operating parameters, the pressure should be adjusted based on the pressure gauge before the reverse osmosis membrane, especially when the system pressure is at the upper limit and the membrane pressure difference is large, this point should be paid more attention to.

12. Low voltage switch is a safety device that controls the operation or stop of the host based on the water pressure value set according to the system process requirements. When the pressure of the raw water supply is lower than the system set value, the pressure switch will automatically shut down the main unit to avoid the high-pressure pump from rotating when there is a lack of water or when there is no water, which may cause damage to the pump.

13. High voltage switch, the equipment is equipped with a high voltage switch, which functions when the system pressure exceeds the rated pressure10%At this time, the high-voltage switch will automatically turn off the host to avoid accidents.
