Process Introduction of 0.5-Ton Beverage Juice Ultrapure Water Equipment

The 0.5-ton beverage juice ultrapure water equipment adopts a rigorous and efficient process to ensure the production of ultrapure water that meets the high standards of the beverage and juice industry.

After raw water enters the system, it first passes through a multi-media filter. This filter is filled with filter media of different particle sizes, such as quartz sand and anthracite, which form a multi-layer filtration structure arranged in a specific gradation.

As the raw water flows through, large suspended particles such as sediment and rust are trapped layer by layer, thereby initially purifying the raw water and reducing the burden on subsequent treatment units.

Next, the activated carbon filter comes into play. Activated carbon, with its rich pore structure and large specific surface area, effectively adsorbs residual chlorine, organic matter, and some pigments and odorous substances in the water. This step is crucial for removing impurities that could affect the taste and quality of beverages and juices. For example, it prevents residual chlorine from reacting chemically with juice components while reducing interference from organic pollutants on the product's flavor.

The water after activated carbon filtration then enters the precision filter. The precision filter uses a microporous filter element with a pore size typically around 5 microns, which further removes fine particulate impurities remaining in the water. This ensures that the turbidity of the water entering the reverse osmosis unit is kept at a low level, preventing these tiny particles from clogging or damaging the reverse osmosis membrane, thereby extending its service life.

The reverse osmosis unit is the core of the entire process. Under the action of a high-pressure pump, the raw water is subjected to a certain pressure to pass through a semi-permeable membrane. The semi-permeable membrane allows only water molecules to pass through, while most salts, heavy metal ions, microorganisms, and other dissolved impurities are retained. The reverse osmosis process achieves a desalination rate of over 98%, effectively removing various ions such as sodium, calcium, and magnesium ions, as well as small organic molecules and microorganisms, thereby significantly improving the purity of the water.

In some process designs, an ultrafiltration unit is also added. Ultrafiltration membranes have relatively larger pore sizes and are primarily used to remove macromolecular colloids, proteins, polysaccharides, and other substances from the water. If these macromolecules are present in water used for beverages and juices, they may cause issues such as turbidity, sedimentation, or spoilage in the product. Ultrafiltration further enhances the clarity and stability of the water, ensuring that the ultrapure water does not adversely affect the mixture with ingredients like juice.

Finally, the water treated by reverse osmosis and ultrafiltration passes through a UV sterilization device. Ultraviolet light disrupts the DNA structure of microorganisms, rendering them unable to reproduce, thereby killing residual bacteria, viruses, and other microorganisms in the water. This ensures that the microbiological indicators of the ultrapure water comply with food hygiene and safety standards. Some equipment may also include an ultrafiltration safety filter at the terminal stage to filter out any potential tiny particles or microorganisms once again, guaranteeing stable and impeccably pure water quality as it enters the beverage and juice production process.

Through the synergistic action of this series of process steps, the 0.5-ton beverage juice ultrapure water equipment can stably and efficiently produce ultrapure water that meets the stringent requirements of the beverage and juice industry. This provides a solid foundation for producing high-quality, pure-tasting, brightly colored, and safe beverage and juice products.
