250 Liters Per Hour Small Scale​ Reverse Osmosis Water Treatment System

Preparation principle of reverse osmosis water treatment equipment:

The reverse osmosis water treatment equipment is usually composed of three parts: raw water pretreatment system, reverse osmosis purification system and ultra-purification post-treatment system. The main purpose of pretreatment is to make the raw water meet the requirements of the reverse osmosis membrane separation module and ensure the stable operation of the reverse osmosis purification system. Reverse OSMOsis membrane system is the most economical and efficient purification method to remove more than 98% ions, organic matter and 100% microorganisms (theoretically) in raw water at one time. The ultra-purification post-treatment system further removes trace ions, organic matter and other impurities in reverse osmosis pure water through a variety of integrated technologies, so as to meet the final water quality requirements of different uses.

Unique Characteristics of RO Water Treatment System
1. The single-membrane desalination rate can reach 99%, the desalination rate of the primary reverse osmosis system can generally be stabilized above 90%, and the desalination rate of the secondary reverse osmosis system can generally be stabilized above 98%.
2. Because the reverse osmosis equipment can effectively remove microorganisms, organic substances and inorganic substances such as iron and silicon, the quality of the effluent is higher than other methods.
3. The equipment has small footprint, compact structure, reliable operation and convenient operation.
4. The system is simple, the degree of automation is high, the fault is automatically shut down, and it has the function of automatic protection.
5. The recovery rate can reach more than 70%.
6. Save the chemical consumption cost, labor cost and waste water treatment cost generated by regeneration, and reduce environmental pollution.

When using reverse osmosis system, special attention should be paid to raw water pretreatment

In order to avoid blocking the reverse osmosis system, the raw water should be pretreated to eliminate the suspended matter and reduce the turbidity of the water. In addition, sterilization should be carried out to prevent the growth of microorganisms. Since reverse osmosis has high requirements for suspended solids in raw water, a pollution index of water quality polluted by suspended solids is commonly used to detect water quality. This method is to determine the reverse osmosis system is polluted by suspended solids in water. The pollution index of water entering the reverse osmosis system should be no more than 5, and the recommended value is generally less than 3. The pH of the influent should also be taken into account during pretreatment. All kinds of semi-permeable membranes have their most suitable operating pH value, so it is necessary to adjust the pH value of the inlet water according to the requirements of the reverse osmosis membrane. The temperature of the inlet water should also be taken into account during pretreatment. The water permeability of the film increases with the increase of water temperature, but the high temperature will accelerate the hydrolysis rate of cellulose acetate film, and make the organic film soft and easy to compact. Therefore, for the organic film, the temperature is usually controlled in the range of about 20-40℃, the composite film temperature is controlled in the range of about 5-45℃ is appropriate. Reverse osmosis membrane separation technology is the use of reverse osmosis membrane principle for separation, the specific characteristics are as follows:

1. Under the condition of no phase transformation at room temperature, the solute and water can be separated, which is suitable for the separation and concentration of heat-sensitive substances. Compared with the separation method with phase change, the energy consumption is lower.

2. Reverse osmosis membrane separation technology has a wide range of impurities removal.

3, high desalination rate and water recycling rate, can intercept particle size of more than a few nanometers of solute.

4, the use of low pressure as the membrane separation power, so the separation device is simple, simple operation, maintenance and automatic control, on-site safety and health.
