Internal Strainer Basket Series

Big Dipper Internal Strainer (IS) series units utilize an internal strainer basket to capture incidental solids in kitchen waste water flows. A skimming wheel system inside the unit skims the grease & oils out of the retention area when activated by a programmable timer. IS units work well inside fast food-type restaurants or food preparation facilities where grease removal directly at the source is important. Big Dipper IS Point Source Grease Removal Units treat kitchen flows of 15 to 50 GPM (0.95 through 3.15 l/s). There are also larger Grease Removal Units in the IS category that pretreat wastewater flows of 75 and 125 GPM (4.73 and 7.89 l/s).
