Discussion on the operation status of the improved Dalton clarifier and its countermeasures;

In order to give a solution to the incomplete solid-liquid separation of metallic precipitate in conventional chemical precipitation and sand filtration process, a new post-treatment technology was developed for medium- and small-capacity of electroplating wastewater, in which helical-flow clarification was used in combination with diatomite pre-coat filtration process.
