"I bring direct drinking water treatment technology introduced from the Mcgill University in Canada, this technology is pushed out may offend many here related water treatment reagent manufacturers, equipment manufacturers, which may subvert the technology now tap water treatment process." In June 21st the first National Water Forum, from Jiangsu Dage Water Company Limited chairman Ding Nanhua's remark, it caused the audience attention of the leaders, experts, suppliers, media and interest. His report entitled "the exploration and application of the original ecological safe and healthy drinking water treatment technology".
The following is the scene shorthand:
Mcgill University, the use of advanced ozone oxidation + Super oxidation equipment combined with ultrafiltration equipment, from surface reservoirs, rivers and other water treatment operation process does not need to add any chemicals, and no sludge produced by continuous nano microbubble automatic backwash water drainage standard is qualified. The North has been 10 years from the laboratory to test and industrial application in 8 projects, now is the largest scale of 30 thousand tons of water.
Mr. Ding Nanhua stressed: after the launch, now all tap water treatment processes: coagulation reaction, precipitation, flocculation reaction, adding PAC, PAM, dosing clarification, sand filtration, sludge thickening and dewatering machine is not needed, operation cost is low, mainly for the micro polluted raw water, heavy metals, eutrophication and other ingredients to remove the technology, it can effectively remove the turbidity, humidity, algae and odor, Escherichia coli, trace organic compounds, phosphorus, nitrogen, trace COD and BOD, TOC, iron, manganese, cyanide oxidation and pesticide persistence of pollutants, antibiotics, cholesterol, skin care products, chlorine disinfection the by-products in water. The technology extension, two, is a super ozone, two ultrafiltration membrane, but it is the performance of large continuous and stable measurement of ozone, the ultrafiltration membrane must be resistant to oxidation of the membrane, ultrafiltration membrane life is generally 3 years, it was 10 years ago today the film did not change, but also in a very good run.
Ding Nanhua: 2008 Canada DAG company for global patent, including 4 years obtained the patent authorization in Chinese. Standing behind me is one of the inventors, Professor Rali of Mcgill University, who published the technology in English at the end of last year at the national drinking water safety and security conference.
In North America, about ozone, it's a long time. What is the core? Ozone by oxidation in the water after the removal of these pollutants strong oxidation and degassing, flushing process, the amount of strong oxidation is? We call 15 kilograms level, our country at present is generally 1.5 to 3 kilograms.
This is the resistance to oxidation of UF in strong oxidized water into the ultrafiltration process, resulting in a technique called nano micro vesicles technology, through the micro fine bubble collision on the ultrafiltration membrane, after the collision adsorption in ultrafiltration membrane on all the dirty things off in the bottom of the membrane, by compressed air and water. Just wash away, so the backwash is not required for chemical. In North America, it's anti flushing water can reach 4 kinds of water standard discharge.
What is the biggest advantage? It handles a ton of water running costs is 3 cents more money, it does not require agents and artificial, completed by a person on duty. Ding Nanhua said, I went to Canada to see his 30 thousand tons of water, I was surprised that a person on the computer on duty. Running a fairly high degree of automation! Influent turbidity in the 134mg/l, the effluent turbidity in the 0.008-0.009, an hour to see the changes in water."
About compound medicine, antibiotic, cholesterol, skin care products, disinfection of chlorine by-products of these new pollutants can be removed. The greater the tonnage of operation cost, more small, to 500 thousand tons of only 1 wool much money a ton of water.
Qu academician has said: now our country's leaders put forward more, so that people drink without chemical agents of the original ecological safety and healthy drinking water, you develop technology into China was at the time! In addition, the International Water Association IWA has put our technology included in the 2016 year of Australia will publish a list of innovative application of drinking water!
The way of pollutant removal performance and energy consumption comparison: flocculation, ultraviolet, chlorine, activated carbon, ozone, reverse osmosis treatment effect and running cost. Among them, ozone is the most effective, good effect, low energy consumption.
Finally, we introduce the technology invited Professor of Mcgill University and Canada DAGUA company experts respectively to the Tsinghua University, Tongji University, Harbin Institute of technology, Beijing Municipal Engineering Design Institute, Shanghai Municipal Engineering Design Institute, National Institutes of health and the CDC, membrane engineering research center of Chinese Academy of Sciences, chief engineer of the relevant experts and scholars in tap water company, ozone and membrane face to face AC.
