ABSTRACT:
This invention relates to a device for regulating a water-removing or drainage machine, particularly a double-sieve sludge drainage machine having a plurality of automatic control means for adaptation thereof to sludges with different drainage properties, comprising an automatic throughput control means in which a sludge level in a filtering zone serves as an indication for the automatic throughput control means, an automatic flocculant control means adapted to employ shearing strength of a sludge-flocculant mixture as an indication of drainage behavior, and an automatic sieve velocity control means responsive in dependence upon drainage velocity.
