Louw was sixth fastest in the semi-finals, clocking 22.02 seconds.
Triple Olympic medallist Roland Schoeman crashed out, however, finishing last of the semi-finalists in 22.42.
Chad le Clos, who was fifth in the men's 200m butterfly final on Wednesday, failed in his attempt to reach the 100m final.
