For something that can get a national patent, it should be considered powerful. Here, I searched the Internet for some specific eight processes, which look complicated and powerful anyway.
First pass: coarse filtration
Filter out large-particle impurities such as suspended solids in water.
The second level: ultrafiltration
Filter out colloids, fine impurities and macromolecular organic substances in water, such as coliform bacteria and silica gel, to avoid adverse reactions such as diarrhea and gastrointestinal infection caused by coliform bacteria. In addition, this process can also escort "RO reverse osmosis" and make the filtered water safer and purer.
The third way: activated carbon filtration.
Trihalomethane produced by the reaction between chlorine and organic matter in the process of chlorination and disinfection of drinking water can cause liver, kidney and intestinal tumors. The process uses activated carbon with high adsorption value, which can adsorb organic matter and remove residual chlorine, trihalomethane and other harmful substances as low as 0.01mg/L/L.
The fourth way: ultraviolet sterilization
Using ultraviolet rays to destroy the DNA of bacteria to kill bacteria, viruses and other microorganisms in water, and fully disinfect them to prevent bacteria or viruses from entering the human body and causing unnecessary harm to the human body.
The fifth way: security filtering.
Ensure the filtration accuracy of water quality and the filter element of protective film is not damaged, so that every bottle of water that consumers drink is more secure.
Level 6: Two-stage RO reverse osmosis
The filtration level that domestic drinking water treatment equipment can't reach is to remove the calcium and magnesium plasma content in water according to the principle of reverse osmosis, to prevent excessive ions from causing stones in the body, and to remove impurities such as dissolved salts, microorganisms, nitrite and heavy metals in water.
Seventh: ozone sterilization
All-round sterilization ensures the safety of consumers. Ozone sterilization can not only kill pathogenic bacteria and microorganisms in water, but also sterilize bottles and caps.
The eighth lane: terminal filtering
The terminal filter is installed in front of the filling machine for the last protection, filtering out impurities with pore size greater than 3μm to ensure the final water quality is pure and safe.
