Direct Known Subclasses:
PressureFilter, RotaryVacuumFilter, ScrewPress, SolidsCentrifuge
public class SolidsSeparator extends ProcessEquipmentBaseClass
Solids separator for bio-processing applications.

Separates a feed stream into a solids-rich (cake/retentate) stream and a liquid-clear (filtrate/permeate) stream. The separation is based on component-specific split fractions that define what fraction of each component goes to the solids outlet.

This is the base class for various solids-liquid separation equipment such as centrifuges, rotary vacuum filters, pressure filters, and screw presses. Subclasses can override the defaults for energy consumption and efficiency.

Usage example: 

SolidsSeparator centrifuge = new SolidsSeparator("Centrifuge", feedStream);
centrifuge.setSolidsSplitFraction("cell_mass", 0.99); // 99% recovery
centrifuge.setSolidsSplitFraction("fiber", 0.95);
centrifuge.setMoistureContent(0.40); // 40% moisture in cake
centrifuge.run();

StreamInterface cake = centrifuge.getSolidsOutStream();
StreamInterface filtrate = centrifuge.getLiquidOutStream();
