Shandong promotes ozone and algae removal technology along the Yellow River

Recently, a technology called “Algaecides for Contaminated Water Sources and New Bioactive Filtration Processes” is expected to change the water quality of the Yellow River so that residents along the banks of the Yellow River can directly drink sweet Yellow River water.
As the water of the Yellow River has been polluted in recent years, the degree of eutrophication has been increasing, resulting in a large number of algae in the reservoir. Algae entering the tap water treatment system not only causes filter clogging, but also easily leads to tap water taste, smelly and colored, which seriously affects the quality of tap water.
The use of conventional tap water treatment methods to remove algae is less than ideal. For example, although chlorine can effectively kill algae, the use of chlorine can lead to the formation of a large number of harmful by-product halogenated hydrocarbons that are carcinogenic.
Professor Gao Tingyao, director of the National Urban Pollution Control Engineering Research Center and former president of Tongji University, believes that this technology utilizes the strong oxidizing properties of ozone to kill algae; the first is a new type of biologically active filter material, and the two technologies can be combined to achieve surface removal. Water algae, organic matter, ammonia nitrogen, etc., to ensure the safety of drinking water. Because the ozone generator has been domesticated, and its stability and price are all suitable, it is possible to promote the large-scale production of this technology.
With this technology, a water plant that handles 10,000 tons of water per day will need to increase investment by more than 700,000 yuan and increase operating costs by 0.065 yuan per ton of water.
