Compression zone data, important in high rate thickener sizing, is also gleaned from static tests. Static thickening tests examine flocculation requirement, hydraulic loading rate, unit area requirements, feed solids concentration sensitivity, and to predict underflow solids concentration for conventional thickeners.
