A laboratory-scale reactor was used to simulate a water treatment process
 sequence of rapid mix, hydraulic flocculation, upflow clarification with
 a floc blanket, and lamellar sedimentation to accomplish removal of colloidal
 particles.
 This study focused on variables affecting performance of the floc blanket
 including: provision of hydraulic flocculation, raw water turbidity, coagulant
 dose, upflow velocity through the floc blanket, and bulk density and solids
 concentrations of the floc blanket.
 An upflow clarifier velocity between 1.0 and 1.3 mm s-1 produced the best
 floc blanket performance for turbidities studied between 10 and 200 NTU
 while an upflow velocity between 0.6 and 0.8 mm s-1 produced the best floc
 blanket performance at 500 NTU.
 The results show that overall particle removal efficiency improved with
 increasing hydraulic flocculator residence time and energy dissipation
 rate.
 Particle removal efficiency improved with increasing floc blanket depth
 for floc blanket depths between 15 and 75 cm.
 Lamellar sedimentation with a capture velocity of 0.12 mm s-1 is a key component
 in improving clarifier performance when utilizing a floc blanket.
