CASE STUDIES
being so thick at the time, we had to try almost 20 times for more than 15 minutes to get the AeriGator in low enough though the thick layer – and to make sure that we were all out of harm’s way. When the scum began to blow out of the nozzle, it was really disgusting – unless you happen to have a liking for thick brown toothpaste! As bubbles began to emerge and the crust slowly began to break up, we could see that it was working. The Facilities Manager was suitably amazed at what this set-up could do. And despite what I’ve said about trying to lower it down, installation of the AeriGator is actually very easy; an operator could set up themselves in an afternoon”.
Such was the speed and efficiency of the new equipment that wisely, Smith Environmental held back on clearing all of the tank’s crust at once, so as not to overwhelm the DAF plants, with what would have been a long continuous slug of fat. Some fine- tuning of the operation is still in progress, but now that the crust is no longer present, the meat processor’s DAFs receive a far more consistent flow from the now blended equalization tank. This allows discharge consent for final effluent to be met without the previous variations – also caused by the fluctuations of the chemicals that were being added to combat the bad odors.
“The acquisition of just this one pump will make a big positive difference to the bottom line at the meat processor”, continued Paul Matrka.
“The Landia AeriGator will easily pay for itself in just two years”.
He added: “This site was unique, as there weren’t any significant complaints about the foul smell, but at a location with near
neighbors, an odor problem is a serious issue, with no end of negative publicity. The AeriGator now runs 24/7, with no fuss, making those odors a thing of the past. Our Facilities Manager customer is now such a champion of this product that every time I see or talk with him, he’s selling its benefits to me. It’s made a huge difference to the plant”.
