PPG announces ACCU-TAB wastewater tablets for aerobic and on-site systems


PITTSBURGH, – PPG Industries (NYSE: PPG) has introduced ACCU-TAB(R) wastewater tablets that provide enhanced erosion control and reduced wicking to effectively kill bacteria, control algae and destroy organic contaminants in small-scale aerobic water treatment systems.

Patented Accu-Tab calcium hypochlorite wastewater tablets are manufactured with HI-SIL(TM) H-303 silica to provide a steady source of available chlorine. The PPG-engineered silica is an erosion modifier that replaces aluminum stearate, which can be violently reactive under certain environmental conditions. Accu-Tab wastewater tablets are compatible with standard 2 5/8-inch feeders, contain 73 percent nominal available chlorine and are made and serviced in the U.S. with no foreign materials. The tablets have a beveled edge and smaller 2.5-inch diameter to reduce wicking.

Most on-site aerobic wastewater systems that treat up to 250,000 gallons per day, including those for residential sites, apartment complexes and small commercial sites, can use Accu-Tab wastewater tablets.

“PPG has been providing private-label calcium hypochlorite tablets for wastewater applications and NSF-certified tablets for drinking water for more than 20 years,” said Mike Hoops, PPG business manager for calcium hypochlorite products. “We have built upon that experience to create this next generation of wastewater tablets that provide simple and effective disinfection with minimal maintenance and high reliability.”

U.S. Environmental Protection Agency-registered and certified to NSF/ANSI Standard 60, Accu-Tab wastewater tablets are available through a nationwide network of distributors.
