Pure Water Equipment | Paper Manufacturing Industry

I. Paper industry water quality requirements and equipment selection background

 Paper industry as an important industry closely linked to economic development, with complex processes, resource consumption, pollutants and other characteristics. In the production process, the water quality of product quality and production links have a significant impact, so we must pay attention to water quality issues, the use of industrial water purification equipment, based on actual demand, the use of primary or secondary industrial water purification equipment to produce pure water for production.

Ⅱ. Product Details of Pure Water Equipment for the Paper Manufacturing Industry

1. Brand: Qingqingquan - industrial water purification equipment

2. Model: 100% professional customization, according to the paper industry can be flexibly customized for different production scenarios and needs.

3. Water production capacity: ranging from 0.25 tons/hour to 1000 tons/hour, which can meet the water demand of different scales of paper industry production.

4. Inlet water quality: municipal tap water or well water, from a wide range of sources, adaptable.

5. Effluent water quality: meet the customer's requirements of pure water quality.

6. Conductivity range: 0.055µS/cm~10µS/cm, reflecting the ion content in water, the lower the value, the purer the water quality.

7. Resistivity range: 1Ω-m ~ 18.2Ω-m (at room temperature 20°C), the higher the resistivity, the purer the water quality, to meet the paper industry's high standards for pure water.

Ⅲ. Working Principle of Pure Water Equipment for the Paper Manufacturing Industry

1. Reverse osmosis industrial water purification equipment and osmotic pressure:

  Reverse osmosis water purification equipment phenomenon is common in nature, such as cucumbers into the brine will become smaller due to the loss of water, the brine level rises to a certain height to reach equilibrium, at this time, the difference in the liquid level at both ends of the diaphragm represented by the pressure is the osmotic pressure, and the size of its brine concentration is directly related.

2. Reverse osmosis phenomenon and reverse osmosis water purification technology:

 Device equilibrium, in the brine end of the liquid surface on the application of a certain pressure, water molecules will be from the brine end of the migration to the pure water end, this liquid molecules in the pressure by a dilute solution to the concentration of the migration phenomenon is the phenomenon of reverse osmosis. In the brine end of the pressure applied over the osmotic pressure of brine, at the other end of the pure water can be obtained, this is the principle of reverse osmosis water purification.

Ⅳ. Technical Process Features of Pure Water Equipment for the Paper Manufacturing Industry

1. Advanced technology integration: the system adopts advanced reverse osmosis, ion exchange, EDI and ultrafiltration technology, as well as PLC automatic control technology, on-line instrumentation monitoring and other advanced technologies to ensure the stability and efficiency of the water production process.

2. Wide range of raw water quality: according to the characteristics of the separated or concentrated medium, imported reverse osmosis membranes with different membrane materials, pressures and desalination rates are selected, which are suitable for a wide range of raw water quality.

3. Perfect pre-treatment system: according to different raw water quality, it adopts iron and manganese removal, organic matter removal, residual chlorine removal, softening or dosing equipment as the pre-treatment system, which effectively removes sediment, rust, organic matter, residual chlorine and other impurities in the water to ensure the safe and effective operation of the membrane host.

4. Comprehensive disinfection function: with ultraviolet rays, ozone disinfection function, so that the water quality is thoroughly purified, to prevent microbial contamination, to protect the health and safety of water production in the paper industry.

5. Precise water quality monitoring: advanced water quality monitoring instruments can accurately and timely test the water quality to ensure stable and reliable water quality.

6. Stable and reliable operation: self-control program, stable water production, simple operation, imported membrane module to ensure water quality, reduce the difficulty and error of manual operation, improve production efficiency.

V. Installation Precautions

1. Site Requirements: The equipment installation site should be level, clean and tidy environment, close to the power supply and water source, which is convenient for equipment operation and daily maintenance.

2. Fire safety: please do not close to the fire source and any heat generator, to prevent equipment damage due to high temperature or cause safety accidents.

3. Special requirements of the region: the equipment should not be installed outdoors in cold regions to prevent the equipment from freezing inside, damaging the instruments and filter elements and affecting the normal use of the equipment.

4. Drainage requirements: equipment installation location should be able to facilitate drainage, so that the equipment drain pipe to maintain smooth, to avoid the accumulation of water affecting the performance of the equipment.

5. Water pressure and flow requirements: when the water pressure < 0.12Mpa, flow < 2.0T / H, the machine will repeatedly appear in the operation of the multi-stage pump start - stop - start the phenomenon, at this time should be discontinued to prevent burning the motor. Areas with insufficient water pressure and flow rate, please increase the raw water tank before this equipment.

6. Pump working pressure requirements: the paper industry manufacturing industrial water equipment used to ensure that the working pressure of the pump in the 1.2 - 1.5Mpa, to ensure that the pump in its rated head range, to extend the service life of the pump, to ensure the stable operation of the equipment.
