			* '''Optimal Dimensions''': Aim for a height to diameter ratio (H/D) of 0.5-1.0, with newer installations favoring lower values. This ratio promotes faster settling due to the larger diameter and reduced height.

The entry velocity should be 3.5-5 m/sec, injected at a 20-30° angle to the vessel tangent, about 1 m from the vessel floor for maximum energy conversion efficiency. A flow rate below 2.4 m/sec during transfer from the kettle helps minimize trub floc break-up.

* '''Mashing Process:''' Avoid excessive shear forces during mashing to prevent the formation of gelled proteins, which can hinder trub formation.
* '''Wort Transfer:''' Minimize shear forces during wort transfer from the kettle to the whirlpool by using a slow-running pump with an open-throated impeller and maintaining a transfer velocity below 1.3 m/s.
