In another plant, again Waterhouse was called upon to help find a solution to an issue that had been plaguing the plant for years. This particular plant had been using a polymer on their DAF thickener and had been unable to get their TSS levels down to a reasonable level without dosing a LOT of polymer. On top of this, their operators were regularly being called out in the middle of the night to plant issues related to their DAF.
While the previous supplier had been in the plant for over two years, they had been unable to find a solution to the issues with the DAF, and consequently gave up. In their view, the problem had no solution and that was just the way the equipment would run.
After a series of jar tests and another two days of plant trials, Waterhouse was able to not only reduce their polymer dosage by a staggering 70%, we were able to increase their solids being thickened, and reduce their TSS levels by over half.
