Can the water from the water purifier be drunk directly?

Human life cannot be separated from water. Fresh water is very scarce, so now a lot of it is groundwater or river water, which then passes through a water purifier before being consumed by people. The main function of a water purifier is to remove impurities and some harmful substances in water. So can the water in the water purifier be drunk directly? Next, follow the editor to learn in detail whether the water in the water purifier can be drunk directly!

1. Reverse osmosis principle in water purifier:

When the same volume of dilute solution and concentrated solution are placed on both sides of a container with a semipermeable membrane in between, the solvent in the dilute solution will naturally pass through the semipermeable membrane and flow to the concentrated solution side. The liquid level on the concentrated solution side will be higher than that of the dilute solution by a certain height, forming a pressure difference and reaching an osmotic equilibrium state. This pressure difference is the osmotic pressure. If a pressure greater than the osmotic pressure is applied to the concentrated solution side, the solvent in the concentrated solution will flow toward the dilute solution. The flow direction of this solvent is opposite to the original osmosis direction. This process is called reverse osmosis.

2. Principle of screen filtration:

Use 1μm or 5μm PP cotton polypropylene fiber filter to remove floating matter and particulate matter larger than 5μm in the water to clarify the water source; use 5μm CTO pressed-bonded rod-shaped activated carbon filter to effectively absorb foreign color and odor in the water, partially remove organic and inorganic impurities, effectively absorb residual chlorine in the water, and improve the taste of the water. It is only suitable for high-quality drinking water sources. The taste is better than single-stage filtration. Generally, tap water cannot be drunk raw after being filtered.

3. Principle of microporous ceramic filter element:

The 0.5μmCF all-diatom microporous ceramic filter element can remove rust, red worms, floating matter and particulate matter larger than 0.5μm in the water to clarify the water source; the 5μmCTO pressed-bonded rod-shaped activated carbon filter element can effectively absorb discoloration and odor in the water, partially remove organic and inorganic impurities, and can effectively absorb residual chlorine in the water to improve the taste of the water; the 0.1μmCF all-diatom microporous ceramic filter element can remove Escherichia coli, Salmonella, Staphylococcus aureus, Pseudomonas aeruginosa and mold pathogens larger than 0.1μm in the water; the PPF polypropylene fiber + UDF coconut shell granular activated carbon two-stage filter element can remove discoloration and odor in the water, making the purified water taste sweet and fresh. It is suitable for general tap water sources and cooperates with the pre-treatment process. The treated water reaches the CJ94-1999 drinking water quality standard and can be drunk directly. It tastes better than three-stage filtration.
