High water costs led Primo Gold Cob to Grander Technology but it was the added benefits that created the enthusiasm that has turned former General Manager Des Nolan into one of the biggest advocates.

“The original need to look at Grander was brought about by the fact that we buy water from the council and were paying more to sell it back to them. “We were paying $1.96 a kilo-litre to the council to take our waste-water, which was more than double what we were paying to buy the original water. We had a need to reduce BODS etc,” he said.

 “The first two to three weeks we found pieces of matter six inches long and the diameter of the pipe coming out into our pit and that lasted about three weeks. After that, we started to notice changes.”

“Our biggest real change was the fact that the factory totally lost all its odours and still to this day has no meat smells. That confirmed to me that all our odours in factories are remnants of floor matter that comes back up through the drainage system.

“We noticed the aluminium started to brighten up and in the mornings there was no residue from the previous day’s cleaning in the ceiling, walls or evaporator units. The floor was constantly clean to the point that it looked like it had just been laid a couple of days before.”

Des believes the most significant thing was that BOD and suspended solid levels dropped around 2500 part per million to 600 to 800 parts per million. “In simple mathematics, that changed the cost the council charged us from $1.96 to 84c a kilo-litre, and it has maintained.”

“The overall savings in a year in money back to the council was considerable. I also believe we have helped Wacol sewage complex with the nature of the volume of water we have put through it has a higher oxygen content and that in itself is working in a manner no one even knows about.”
