Because pollution costs money and foundries
can spend funds more productively elsewhere

High production green sand foundries are under increasing pressure to reduce hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) that are emitted during pouring, cooling and casting shakeout (PCS). Smoke and odor from PCS emissions are a serious concern in the workplace environment and a source of neighborhood complaints. In 1988, the State of Wisconsin established regulatory limits for the HAP benzene at 300 lbs/yr and for the HAP formaldehyde at 250 lbs/yr. The U.S. Environmental Protection Agency in August 2003 established a VOC emission standard of 20 ppm for new PCS lines at iron and steel foundries. Since most end-of-pipe treatment systems such as thermal oxidizers are energy intensive and expensive, the foundry industry needs alternative pollution prevention strategies that economically comply with ever more demanding air quality requirements. The Sonoperoxone® treatment system prevents pollution at its source by improving the ability of the sand mold to adsorb the HAPs and VOCs.

Sonoperoxone® systems reduce pollutant emissions to meet increasingly stringent government regulations and to satisfy increasingly activist neighbors.

Because bond costs money and bond usage
is reduced with Sonoperoxone® and Pneu-Col®

The advanced oxidants generated by the Sonoperoxone® process interact with the clay and coal in the bond to make them more efficient. Clay activation increases and coal usage drops. Sand strength per unit of clay increases. Foundries with Sonoperoxone® Blackwater systems have seen their bond consumptions drop by up to 40% by combining bag house dust recycle with advanced oxidant activation.

Sonoperoxone® systems make a foundry more competitive by simultaneously reducing bond consumption and pollution.
