in the lower portions of the upper chamber mix box wall.
The other dimensions and suggested reinforcement could
remain the same.
CONCLUSIONS
The updated design has reportedly been maintenance-free
over the past decade. Additional mix boxes have since been
replaced in other plants across the property with similar
results. Shut-downs, worker exposure to the hazards of the
previous repair approaches, and solution losses to contain-
ment have been in large measure eliminated due to the
strengthened mix box design.
