Method&Equations
This composite item works as a dilute equipment. That is, it dilutes the inlet stream to the desired vat consistency using the second shower stream inlet plus the first shower stream after the first pass. Pulp from the vat is washed with the first shower stream and pulp stream is deckered until desired outlet consistency is obtained.
If the shower flow is zero, the washer model acts like a 'decker' and only dewaters the pulp to outlet mat consistency. No displacement takes place in liquor flow.
All solids (pulp, etc.) are assumed to leave with the outlet pulp stream.
