Improve Clarifier and Thickener Design and Operation

A design method for thickeners and clarifiers known as the batch flux curve technique was developed over 20 years ago, but still is not well known in design and operating circles. An informal survey of major clarifier and thickener manufacturers found that none of the firms surveyed use this method for sizing and maximizing operating conditions.

How to Size a Thickener Mineral Processing Metallurgy

Normally a 25 per cent factor of safety is allowed in determining the thickener area size. Thus, in the above case, 8.87 (largest of three figures) plus 25 per cent factor of safety, equals 11.09 square feet area required per ton of dry solids fed to the thickener per 24 hours.
