A food-grade 304/316 stainless steel sealed water storage tank designed for storing purified water produced via reverse osmosis. It is equipped with an air vent filter and a liquid level sensor; the sealed design isolates the water from air and dust to prevent secondary contamination, ensuring a stable supply to the subsequent sterilization and filling processes.

This is a physical sterilization device that uses ultraviolet light to destroy the genetic material of bacteria and microorganisms, thereby eliminating *E. coli* and algae in the water. It involves no chemical additives and does not alter the water's taste; installed at the outlet of the water storage tank, it continuously inhibits bacterial growth in stored purified water, offering a safe and eco-friendly solution.

RO serves as the core component of the water purification system, capable of removing over 97% of dissolved salts and more than 99% of colloids, microorganisms, particulates, and organic matter. It features automatic membrane flushing, high/low-pressure protection, and online water quality monitoring, ensuring consistent product water quality.

Raw water pump serves as the primary power unit for the water system, drawing tap water or groundwater and delivering it to the pre-treatment stage. Featuring a pressure-resistant and corrosion-resistant stainless steel housing and adjustable pressure settings—along with low-pressure/water-shortage protection—it ensures a stable, constant flow of water to the various filtration units.

This precision protective device for RO inlet features a built-in 5μm melt-blown filter cartridge that captures fine impurities and carbon fines remaining from the pretreatment stage, preventing particles from scratching the RO membrane. It offers easy cartridge replacement and multi-level pressure protection, thereby extending the service life of the RO membrane and reducing consumable costs.

Ozone sterilizer serves as an advanced treatment process for finished water, providing powerful sterilization and bacteriostatic effects that extend the shelf life of bottled and barreled water. The ozone blends thoroughly with the purified water, ensuring comprehensive sterilization with no dead zones and leaving no residue.

Quartz sand filter: This unit removes suspended impurities and reduces water turbidity.
Activated carbon filter: This unit removes color, odors, and microorganisms from the water.
Sodium ion exchanger: This unit softens the water by removing calcium and magnesium ions.
