3.3.1 MANUFACTURER SIZING GUIDELINES -
FOR ALL PROCEPTOR GMC MODELS EXCEPT PDI & CSA CERTIFIED MODELS
STEP 1: Determine Flow Rate
Determine the peak flow rates (Q): add up all the fixture loads discharging to the grease separator (these include: rinse, prep,
3-compartment sinks, floor drain, mop sink, etc.) and establish peak flow rate by dividing fixture capacity by the drain down
time (one or two minutes depending on local code).
If fixture quantity and/or volume are unknown, assume worse case scenario by establishing peak flow rate based on drain size
connecting to grease separator. For example: 4 in drain at 1/4 in/foot or 2mm/100mm = 110 US gpm
STEP 2: Determine Hydraulic Retention Time Required
In order to meet a 100 mg/l euent discharge regulation, Proceptor separators require the following hydraulic retention time (HRT):
• 5 minutes retention for non-emulsified grease
• 30 minutes retention for emulsified grease from sinks only
• For heavily emulsified wastewater, call a Zurn Green Turtle representative for assistance
STEP 3: Calculate Size of the Proceptor
Multiply the peak flow rate (Q) by the hydraulic retention time (HRT) to determine the volume of the separator (V)
V = Q x HRT
STEP 4: Choose a Proceptor Size
Choose the Proceptor size equal or closest to the value of V. Please refer to Grease Separator Sizing Chart in Section 3.3.2.
For example:
1 Restaurant with wash sink (30 US Gal) at one minute drain down time = 30 US gpm
Recommendation: 30 US gpm x 5 minutes = Proceptor GMC 150 US Gal
2 Restaurant with 3-pot sink (30 US Gal) with soaps at one minute drain down time = 30 US gpm
Recommendation: 30 US gpm x 30 minutes = 900 US Gal = Proceptor GMC 1000 US Gal
For high flow rates or high grease content in wastewater such as from large commercial and industrial applications, please call
for a Zurn Green Turtle representative for support.
