Cleaning 2.3
1. Thoroughly clean the decanter immediately after stopping the supply of feed
material and before stopping the motor.
Max. water temperature 80° C.
Water consumption and flushing periods: depending on product
Note: If the decanter is not cleaned as required, restarting will
be complicated, especially after storage periods, due to
product deposits.
2. Cleaning procedures
2.1 Cleaning the bowl interior and the scroll (15 min)
- stop feed / flocculant introduction
- feed water through feed pipe and flush machine
- operate skimmer between min. and max. diameter several times:
at min. diameter liquid will flow through solids discharge openings
after some time and flush the solids housing
- as soon as effluent is clear water:
turn skimmer to max. diameter, stop supply,
turn off decanter and wait until rotor stops,
adjust skimmer to standard diameter
Note: After turning off the decanter, close centrate shut off valve, if centrate is
conveyed to a rising drain pipe without pump via the skimmer, otherwise main
bearings may be flooded by return flow of the head of liquid to the skimmer.
2.2 Flushing skimmer chamber via centrate line
- at 1/2 speed (1st motor step or with rotor slowing down)
introduce water until it flows over at the solids discharge side
- repeat several times if required
- switch off decanter
