We are trying to decide on whether to use a column supported clarifier or a bridge supported clarifier. Is one better than the other?
Based only on cost, a bridge supported clarifier is more economical at about 50 ft diameter and below. Column supported clarifiers tend to provide better cost at 40 ft diameter and above. Yes, there is an overlap between 40 and 50 ft diameter. Site, project and process specific conditions may be factors which need consideration when choosing between the two types of clarifier. This should be discussed with Ovivo or your local Ovivo Representative. We would be happy to assist.
