Drain-Net offers the number one Point Source Grease Recovery Unit, the Big Dipper® to treat kitchen drain flows of 20-50 GPM.  This unique system removes grease and oil form free kitchen drain water.

These units are engineered to treat single fixtures such as a three compartment sink or pre-rinse station. Big Dipper Point Source Grease Traps are typically found in fast food & full-service restaurants, schools, grocery stores, hotels, commercial kitchens and similar establishments.


Benefits of the Big Dipper®

Grease buildup within a building’s plumbing drainage system is a major cause of problems due to drain line blockages.  These problems jeopardize normal operations as well as create health and safety hazards within the facility itself.  Proper installation of a Big Dipper System can reduce or eliminate grease problems.  Use of the Big Dipper assures minimization and/or elimination of costly sewer surcharges and fines through efficient separation and removal of free-floating grease & oils.  In addition, the Big Dipper also helps reduce or eliminate pumping and disposal costs associated with conventional grease traps or interceptors.  The recovered grease & oils are substantially water-free and are suitable for recycling by local rendering and/or biodiesel companies.


How the Big Dipper® works


The 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 gallons per minute.  There are also larger Grease Removal Units in the IS category that pretreat wastewater flows of 75 and 125 gallons per minute.

Performance

The most important characteristic about Big Dipper® removal systems is that they work. There are countless success stories. One nationally known fast food facility cut grease trap pumping costs by over $25,000. A large hospital in the Northeast saved an estimated $50,000 a year in fines and maintenance costs by installing a Big Dipper®.

Big Dipper® systems solved a huge grease problem at two Puerto Rican prisons and weekly remove more than 100 gallons of grease from each prison. Furthermore, in most applications, the recovered grease can be recycled and used in bio-diesel fuel, cosmetics, animal foods and more.

What size Big Dipper® / model number is right for me?
