Connections and Hook-ups
Complete each element carefully, one at a time:
Delivery of thickened sludge, if possible, should be by simple gravity slide. This
method serves two purposes: (1) there is no possibility of an overload condition
developing as might be the case where a pump is employed, and (2) any
downstream requirements for further dewatering derive great benefit from residual
polymer activity which is not the case where pumping is practiced. The residual
polymer benefits are also recognized where a simple belt conveyor is used.
Where pumping thickened sludge is employed, efforts should be made to minimize
the pumping distance, avoiding any line constrictions and right angles.
For return water delivery, if possible, provide short rigid line(s), avoiding flow
restrictions such as right angles.
In the line delivering untreated sludge to the flocculation tank, provide a chemical
injection point, located according to the manufacturer's recommendation. Also on
the line delivering untreated sludge, provide a valved drain down-line for the flock
tank immediately preceding the flock tank inlet. A common practice is to drain the
flock tank to the return water destination. Your ability to do this will depend on your
return water restrictions.
A fresh water supply for the chemical makeup and feed system is preferred but
plant water may be used for this application. A 1” flexible hose will be supplied for
installation between the booster pump and the spray wash header. Carefully size a
line from the plant water source to the washwater booster pump, so to provide
adequate flow.
Initial Lubrication
See MAINTENANCE SECTION for Lubrication and Maintenance requirements.
Before rotating the drum, verify the trunnion wheels are packed with grease.
Grease should be observed around the bearing seals. If necessary, using a grease
gun, fill the interior of the wheels with sufficient grease to pack the void inside. To
ensure wheels are fully greased, continue until grease is observed exiting from the
seals of the bearing.
Grease or oil the rotary drum drive chain.
All gearmotors and gear reducers are supplied with the correct grade and quantity
of lubricating oil based on mounting position. Check oil levels before first operation.
For additional details refer to the Component Data for Gearmotors.
