摘要

Control device flocculation in a stream of sludge or sludge and system for controlling flocculation by adding flocculating reagent into said stream of sludge or sludge. # The device (A) is provided with a container probe (2) arranged consecutively and in a different position and a filter (3) capable of dividing the container into two parts, where each probe is configured to provide a signal indicative of the presence or absence of sample in each position, allowing the difference in position between said probes calculate the degree of flocculation of the sample in the time elapsing between each signal time. The system comprises the device (A) adapted to measure the time passing the sample and adapted to provide a signal indicative of said change of time period, and a processor having a ratio of the time interval has elapsed, adapted to receive a signal device, for processing with that relationship and provide another signal acting on the amount of flocculating reagent introduced into the system.
