I was called in 20 years ago by a chicken QSR to develop a product to treat their grease trap. They faced high pumping costs yet still needed to pump out the traps every two weeks for control of odors and grease discharges to city lines. While walking through numerous locations before opening hours, I noticed the odors and discovered they often had two plumber call outs per month for clogged floor drains. This led to a new microbial/enzyme application that had the potential to solve multiple problems.
The result of a few changes in the formulations was a new product for use in mopping/cleaning floors. At the end of the night, employees switched from using surfactant cleaners and bleach to a new biodegradable surfactant/microbe/enzyme blend. The residual cleaning solution in the mop bucket was dumped in to the floor drains after cleaning.
A quick side note, even through we often try to "Kill 99.9% germs", microbes are vital for the environment and necessary for our digestive process. The microbes found in the product are beneficial organisms found throughout the environment and are important waste degrading bacteria. They are similar in effect to the probiotic cultures taken by millions of users every day.
The product was simple in formulation yet very effective. The surfactants and enzymes provided for immediate clean with the enzymes helping to deep clean the tiles and grout. In the drain lines, the microbes in the product began to grow and degrade residual organics removed in the cleaning. When used nightly, the results were remarkable:
- Grease traps were less odorous, no grease cap and pumping frequency reduced to once every 5 - 6 weeks from a previous every 2 weeks
- Emergency plumber call outs for grease clogged floor drains/lines fell by 60%
- Mystery odors were controlled by the microbes degrading rancid grease behind equipment and in tile grout that was left by previous cleaners
- Drain flies (fruit flies) decreased significantly as the number of breeding sites was decreased through better cleaning/sanitation
