Wastewater Technology, Inc.

Welcome to Wastewater Technology, Inc.

In 1990 we installed our first wastewater treatment plant for a church camp near the Town of North East,
Maryland. Today we have over 70 installations in the U.S., Eastern Europe and China. We can furnish
"packaged" treatment plants in steel tanks, which are preassembled in the shop, or we can provide the
Bio-Wheels™ and other equipment to be installed in locally constructed concrete tanks.

Bio-Wheel™ treatment plants can be designed to discharge wastewater with less than 5 mg/L BOD and TSS,
3 mg/L total nitrogen and 0.5 mg/L phosphorous to meet the requirements of the 2010 EPA standards for
discharge into the Chesapeake Bay and other protected waters. Many of our facilities discharge to sub-surface
irrigation systems which are used for crop or golf course irrigation.

Our newest product is the Bio-Brane™, which is a Bio-Wheel™ followed by a membrane, eliminating the
clarifier or filter. With the Bio-Brane™, we can achieve effluent BOD and TSS almost to non-detectable limits.

The Bio-Wheel™ is a very cost effective and operator friendly method of municipal, domestic and industrial
wastewater treatment. Operating and electrical power costs are very low, and a smaller footprint is required
because of the efficient combination of fixed film and activated sludge processes.

treatment needs and requirements. Please call at 800.741.8941 or send an email to info@bio-wheel.com for
