| titleOfInvention | Method and apparatus for high-speed coagulation and sedimentation of suspended water |
| abstract | PROBLEM TO BE SOLVED: To provide a high-speed coagulation-sedimentation method and apparatus of suspension water capable of remarkably improving the recovery rate of mineral particles from coagulation-sedimentation sludge by a simple operation. SOLUTION: An iron or aluminum-based inorganic coagulant and fine mineral particles having a specific gravity of 2 or more, such as sand and magnetite, and an organic polymer coagulant are added to raw water to form a floc incorporating the mineral particles and precipitate and separate. In the method, a mineral acid is added to the sludge containing mineral particles separated by precipitation to dissolve iron hydroxide or aluminum hydroxide floc, and then the mineral particles and other SS are classified using the difference in sedimentation. A high-speed coagulation-sedimentation method comprising collecting and returning the recovered mineral particles and a liquid containing iron or aluminum ions to raw water. Equipment for that. |
