From groundwater to safe and pure water for drinking there are many important filtration steps in the middle, we often ignore the role of protection or packaging role of the filtration process, and ultimately can not get pure water, let us understand the specific purified water filtration steps.
This is one of the key steps in the purified water filtration process. Prior to treating surface or groundwater, the water is treated and softened using a filter to protect the reverse osmosis or ion exchange unit. This helps remove impurities and hardness from the water and ensures that subsequent treatment steps operate efficiently.
Before the water enters the deionization system and the bottling line, it is passed through a pre-filter to remove fine particles and suspended organics. This helps to reduce the burden on the subsequent treatment equipment and ensures the cleanliness of the water.
As the last line of defense before bottling, final filtration aims to reduce biological contaminants. This includes the removal of microorganisms such as bacteria, capsules and viruses to ensure that the final product meets hygiene standards.
During the bottling process, the exhaust ports of the gas storage tanks need to be filtered. This ensures that sterile air can pass through during filling and venting, while protecting the tank and its contents from contamination.
Filters play an important role in the bottling and packaging stages in the presence of CO2 or N2. They effectively remove airborne contaminants and ensure that the final packaged purified water remains pure at the factory.
By carefully designing and implementing these steps, manufacturers can ensure that they provide a high quality, safe and pure purified water product that meets consumer demand for healthy drinking water.
After understanding the steps of filtration from surface water to purified water, you may still have some questions about how to choose the right purified water filter, the following content will tell you what kind of filtration elements you should pick at different stages to ensure filtration efficiency.
Pleated cartridge filters made of PP or fiberglass are recommended. PP pleated cartridge filters are known for their chemical resistance, low cost and uniform microporous distribution, making them an economical pre-filter choice for removing particulate matter. Fiberglass pleated cartridge filters are suitable for handling chemically complex liquids. The filtration accuracy is progressively filtered from greater than 10 microns down to 1 or 5 microns to protect reverse osmosis and ion exchange units.
A 5 micron pp or glass fiber filter cartridge is installed between the ion exchange unit and the water storage tank to prevent the entry of broken beads.
Control bioburden class hydrophilic polyethersulfone membrane pleated cartridge can not only filter out microorganisms in water, such as bacteria, encapsulation and virus, etc., the price is more economical, if the budget is sufficient to pursue higher filtration effect, you can choose the sterilization model of PES membrane pleated cartridge. The filtration precision can be chosen from 1~10μm as the final filtration before bottling.
Usually the filtration precision is 0.2μm, and the cartridge should be hydrophobic and bacteriostatic to prevent moisture and microorganisms from entering the gas storage tank. Hydrophobic PTFE membrane pleated cartridge filters are recommended.
As above, hydrophobic PTFE membrane pleated cartridge filters are recommended, with a filtration accuracy of 0.2 microns, hydrophobic and bacteriostatic properties to prevent moisture and microbial contamination of the finished product.
