查询词典 coagulants

The high turbidity problem in water out of the cyclofloc always exist in Pech?-David water treatment plant at Toulouse in France. Compared with the other water treatment plant at Toulouse, the turbidity of Pech-David was 2.3NTU and was higher than that of Clairfont as 0.5NTU. Coagulation jar-tests with several coagulants and coagulation aids from Floerger and Ciba company were studied to solve this problem.
