Thioguard Takes the Cake...and Makes it better.

For a nearly one million gallon a day plant in Lambertville, NJ the good news just kept on coming.

First, they started using Thioguard to condition their primary sludge to reduce odors from the plant.  This worked so well, they began to ask, “Where else could it be applied?”

As the winds whipped in early Spring, it was discovered that a significant amount of odor was coming from the nearly quarter million gallon sludge holding tank at their site.  Since it worked to reduce the primary sludge odors, they wondered if it could work for stored sludge waiting to be pressed.

After establishing a stable pH range of 7.5-8.0 su, with just a couple gallons a day, odors were reduced to satisfactory levels...and then something very interesting happened.   Not only were odors in the press building reduced, but the press cake was dryer.   On average nearly 20-40% dryer.

It’s true. Why? Thioguard is magnesium hydroxide: A buffered source of alkalinity that is used to increase pH.

Thioguard TST is a nonhazardous application with no required reportable quantities (RQ = None)

This elevated pH promotes better polymer performance.Not only that, but due to the divalent cation bridging, the press supernatant quality can be clearer as well. Any remaining alkalinity is then returned in the supernatant to the headworks of the plant.

Improved polymer and press performance through buffered pH control adding divalent magnesium cation bridging.  Thioguard proves it is a multiple benefit application.
