Q: I want to convert from a suction type clarifier with a flat floor to a spiral bladed clarifier. Will this cause a problem? I understand spiral bladed clarifiers usually have a 1:12 sloped floor.

A:  The spiral bladed clarifier can be designed to accommodate an existing flat floor clarifier. We have numerous installations in flat floor clarifiers. Flat floor typically = slopes of 1/4” in 12”, 1/8” in 12”, 1/16” in 12”.
