pretreatment
Initial conditioning step
Pretreatment is preliminary processing that prepares something for a main treatment.
In medicine, a patient might receive pretreatment before chemotherapy to reduce side effects.
Industrial pretreatment removes contaminants before wastewater enters a treatment plant.
Fabrics undergo pretreatment to accept dyes evenly: The pretreatment made the cotton more absorbent.
