Method of treating low-concentration turbid water |
| abstract |
The present invention provides a method of treating low-concentration turbid water, which comprises adding an anionic coagulant and a cationic coagulant in this order and forcedly stirring the mixture. n According to the present invention, low-concentration turbid water of even up to 100 ppm can be cleaned to below 10 ppm at a high efficiency in a single run of treatment. |
