1. Overview of domestic clean water
a. What is domestic clean water?
- Domestic clean water is water used for daily purposes such as drinking, cooking, personal hygiene, laundry, and cleaning in homes, schools, offices, and public agencies. Clean water is sterile, free of impurities, bacteria, viruses, or toxic compounds. This type of water is very important for the health of humans and living organisms on earth. Clean water can be produced through a water treatment process or collected from natural water sources such as ponds, lakes, rivers, or boreholes.
- According to the General Statistics Office’s report, the total amount of water supplied for domestic use in 2020 was about 6.26 billion m3, of which 2.58 billion m3 were produced by water treatment factories, with the remainder supplied from natural water sources.
- However, the supply of clean water in Vietnam has not yet fully met the needs of the people, especially in rural and mountainous areas. Many areas are still using groundwater that does not meet hygiene standards, posing a danger to people’s health.
- In addition, issues related to the management and monitoring of clean water quality also need to be improved to ensure that the quality of water produced and supplied meets the standards. Furthermore, applying advanced technology and optimizing the manufacturing process are also things that need to be focused on to improve manufacturing efficiency and minimize environmental impact.
b. Types of machinery for domestic clean water manufacturing
The types of machinery and equipment for domestic clean water manufacturing today include:
- Wastewater treatment system: Includes main components such as corrosion treatment tanks, organic decomposition tanks, settling tanks, ion exchange systems, activated carbon filters, organic sludge separation systems, bottom sludge separation systems, etc.
- Water pump: Used to supply water to the treatment system or directly supply clean water to the public. Common types of water pumps include booster pumps, wastewater pumps, submersible pumps, etc.
- Home water purifier: Can filter water directly from a clean water source or from a faucet, removing harmful substances and impurities, ensuring safe clean water for health.
- Industrial water purifier: Used for projects, buildings, and urban areas to produce clean water and supply it for domestic purposes.
