The invention comprises providing sensors (11), in a communication system connected with a control center (10), for determining amount of retarder (4) used and resulting sludge water/concentration. The data is analyzed such that overdoses or insufficient doses of retarder are minimized or prevented. Warnings or corrective signals can then be sent by the control center (10) if needed.
