Traditional sewage deep treatment and recycling technology system for Dalian water treatment equipment.
Water treatment includes physical, chemical, and biological processes. Human water treatment has a long history. Physical methods include using filter materials with different pore sizes, using adsorption or barriers to exclude impurities from water, with activated carbon adsorption being particularly important. The barrier method involves using filter materials to prevent large impurities from passing through, resulting in cleaner water. Additionally, physical methods also include sedimentation, which involves floating smaller impurities to the surface for removal or allowing larger impurities to settle at the bottom for removal. Chemical methods utilize various chemicals to convert impurities in water into substances that are less harmful to humans or to concentrate the impurities. The oldest chemical treatment method is likely the addition of alum to water. Once impurities in the water are collected, their volume increases, allowing them to be removed through filtration.

Revealing wastewater treatment processes on World Water Day
Water is the source of life, nurturing all things and concerning human well-being. However, with the rapid development of industrialization and urbanization, water resources are becoming increasingly scarce, and water pollution is becoming more severe. To make the most of every drop of water, wastewater treatment technology is particularly important. Current wastewater treatment technologies are not only a key part of managing water pollution and improving the water environment, but also an important way to promote the recycling of water resources and achieve sustainable development.
