The liquid mass circulates in the tank in a controlled manner such that submerged parts remain centrally suspended in the tank, regardless of the material, density and geometry comprising the part. The part circulates and rotates in conjunction with the rotational flow of the liquid mass for uniform exposure to means of support removal. During rotation, the part may be subjected to multiple means of agitation that include heat, chemical and ultrasonic, in order to optimize energy use and maximize efficiency of the removal of support material.
