Process for controlling amounts of chemical auxiliaries and flocculating agents in dependence on an on-line mass/solid measurement for clarification and dewatering processes of all types, and plant for carrying out the process

摘要

The invention relates to a process for controlling amounts of chemical auxiliaries and flocculating agents in dependence on an on-line mass/solid measurement for clarification and dewatering processes of all types in accordance with Patent Claim 1, of P 4321994.2 and is to enable further saving of chemical auxiliaries and flocculating agents by achieving a constant solids content in the solids suspension of the particular clarification and dewatering process. For this purpose, from the mass/solids content measurement, a low-solids to solids-free medium is fed into the solids suspension, the feed being controlled in dependence on the continuous determination of the mass/solids contents/mass concentration.
