● Boil water: Effectively kills most bacteria and viruses, but is ineffective against some high-temperature-resistant microorganisms. ● Water filters: RO and UV sterilizers are very efficient at sterilization and virus removal, while ultrafiltration and activated carbon filters are relatively weak.

The reverse osmosis filter passes water molecules through the membrane pores under high pressure through a semipermeable membrane, while pollutants such as dissolved salts, heavy metals, bacteria and viruses are retained on the other side of the membrane to achieve the purpose of water purification.

Reverse osmosis systems use semi-permeable membranes (pore size of about 0.0001 microns) to remove most pollutants from water, including microplastics, nanoplastics, and soluble compounds.

The workflow of a water treatment plant is generally divided into the following main stages: pretreatment, primary treatment, secondary treatment and tertiary treatment. Each stage has its specific goals and technical means.

Traditional water filters usually refer to simple filtration devices that have been widely used in the past few decades. Modern water filters combine a variety of advanced filtration technologies to provide more efficient and comprehensive water purification solutions.

Pros of a water treatment machine: 1. Provide safe drinking water 2. Improve the taste of water quality 3. Protect household appliances 4. Environmental protection and conservation... Cons of a water treatment machine: 1. High initial investment 2. Maintenance cost 3. Wastewater treatment issues...

At present, the common home water purification systems on the market mainly include the following types: ● Water filter kettle ● Tabletop water purifier ● Faucet water purifier ● Pre-filter ● Reverse osmosis (RO) water purifier ● Ultrafiltration (UF) water purifier
