The tank is cleaned by pumping rinsing and cleaning solution upward to the
top of the tank which then cascades downward cleaning the side walls. A special
fitting connects the spray-up line to the overflow line and vent lines so that
the cleaning solution is forced upward through these lines to clean them. No
ladders, catwalks or outside solution lines are required. Servicing the spray
nozzle is easily accomplished through the tank manway. There are no openings
in the top of the tank.
This view shows a typical arrangement of the alcove area with a positively
aligned drive, sump outlet and fittings for level gauge, thermometer, etc.
