The use of 1μm or 5μmPPF polypropylene fiber filter and +UDF coconut shell granular activated carbon filter can remove floating objects and particulate matter larger than 5μm in water, clarify the water source, and the adsorption of activated carbon can effectively absorb odor and residual chlorine in water, thus improving the taste of water. Only suitable for high-quality drinking water sources. Generally, tap water cannot be drunk raw after being filtered.

Two-stage filtration

Use 1μm or 5μmPPF polypropylene fiber filter element to remove suspended solids and particles larger than 5μm in water and clarify water source; Sticking 5μ mCTO rod-shaped activated carbon filter element can effectively adsorb different colors and smells in water, partially remove organic and inorganic impurities, effectively adsorb residual chlorine in water, and improve the taste of water. It is only suitable for high-quality drinking water sources. Better taste than single-stage filtration. Generally, tap water cannot be drunk raw after being filtered.

Three stage filtration

5μmPPF polypropylene fiber filter element, which is used to remove suspended solids and particles larger than 5μm in water and clarify the water source; Sticking 5μmCTO rod-shaped activated carbon filter element can effectively adsorb different colors and smells in water, partially remove organic and inorganic impurities, effectively adsorb residual chlorine in water and improve the taste of water; Using 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 water. It is suitable for tap water sources with good water quality, and with the pretreatment process, the treated water can meet the water quality standard of CJ94- 1999 and can be directly drunk.

Four-stage filtration

Using 0.5μmCF all diatom microporous ceramic filter element can remove rust, red worms, floating objects and particulate matter larger than 0.5μm in water and clarify the water source. Sticking 5μmCTO rod-shaped activated carbon filter element can effectively adsorb different colors and smells in water, partially remove organic and inorganic impurities, effectively adsorb residual chlorine in water and improve the taste of water; Using 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 water; Using PPF polypropylene fiber +UDF coconut shell granular activated carbon two-stage filter element can remove abnormal color and odor in water and make the purified water taste sweet and fresh. Adapted to the general tap water source, combined with the pretreatment process, the treated water can meet the drinking water quality standard of CJ94- 1999, and can be directly drunk, which is better than the three-stage filtration.
