Restaurant Grease Trap

Biological Treatment Summary

The Situation

Two side by side sit down restaurants located in a major shopping mall, with high customer volume, were experiencing grease build up in their grease traps. The grease traps were being pumped every three months with a one to two foot [30.5cm-61cm] grease caps and heavy bottom solids in both grease traps.

The Solution

United-Tech proposed a bioaugmentation program of adding BZT® Waste Digester to decrease the grease cap and bottom solids.

For this program, only one of the restaurants grease traps were treated while leaving the other restaurants grease traps untreated to be used for a control comparison.

The Results

After three months both grease traps were pumped. The untreated grease trap had a two-foot [61cm] grease cap and heavy bottom solids as before. The BZT® Waste Digester treated grease trap had only a slight grease sheen on top of the liquid and had no bottom solids.

This program proved that treating a grease trap with BZT® Waste Digester not only reduces grease caps and bottom solids but also provides the benefits of a faster, easier, more pumpable slurry and increases the capacity and efficiency of the grease trap by breaking down the grease cap and bottom solids.
