POLY-GONE is the most useful tool to diagnose belt blinding from polymer, sludge and basic oil & grease build-ups. Install POLY-GONE feed system as described in POLY-GONE Installation Instructions. Every operator has an optimum method, a habitual way, which they prefer to operate their machine. Once the operator has established a comfortable processing level, increase the sludge in 5% increments:
|50 GPM||52.5 GPM||55 GPM||57.5 GPM||60 GPM|
|100 GPM||105 GPM||110 GPM||115 GPM||120 GPM|
|150 GPM||157.5 GPM||165 GPM||172.5 GPM||180 GPM|
At a certain point, you will affirm that no more sludge will be able to squeeze into the pressure section of the belt press. Note this setting. Recover machine to best processing level.
Remember, this is a controlled experiment in optimum processing. Leave all other settings alone, only increasing sludge throughput. Turn on POLY-GONE pump at maximum levels 100% speed & 100% stroke. Run POLY-GONE for 3 revolutions of the machine, watching for the seam on the larger belt to be your guide.
Reduce POLY-GONE pump to normal operating level. This will draw out a quart to three-eighths of a gallon of water depending on the number of spray bars and the size of the machine. Confirm this dosage with your Schaner’s Waste Water Products, Inc. professional. They can supply you with a POLY-GONE Pump Calibration Instructions.
Increase the sludge, again in 5% increments, to establish the area in which blinding was causing decreases in production. If the Belt Filter Press had blinded belts, you will find the opportunity to increase the sludge 10%, 20%, 30% and occasionally even more sludge, by simply adding POLY-GONE!
This increase in sludge, will not only represent a comparative savings in your polymer use, but also serves as removing the polymer coatings on the solids particulates! Consequently, the solids will separate from the waterside of the process, releasing even more water from your solids disposal side, leaving your belts cleaner during process. The continuing build-up on the belts ceases and optimum dewatering begins. Simply put, by increasing the porosity of the belts, you will use less polymer and quite often see substantial solids reductions in the dumpsters. Facilities who use POLY-GONE during every hour of operations, spend a few dollars an hour on POLY-GONE and save 10, 20 and 30 TIMES that expense in chemical and disposal costs!
