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
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
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.
