Waste Treatment System Tested

Article excerpt

An infectious waste treatment system is expected to be unveiled next month now that tests have been completed, according to Ronald R. Mercer, president of Aegis Waste Systems Inc. of Edmond.

The mobile system, the German-engineered ZDA-M3, was scheduled to be introduced to the central Oklahoma area in August, but the debut was delayed until the tests were completed and the presidential elections were over, according to a company official.

Tests at Presbyterian Hospital by a team of investigators from the University of Oklahoma Health Sciences Center, College of Public Health and Occupational and Environmental Health Department confirmed the system's projections, Mercer said.

"We wanted to make sure the system performed according to the high standards we insist on having in all the services we offer," he said. "It has more than met our expectations, and now we're ready to move ahead. In fact, we're planning a formal unveiling for January."

Using a process of thermal sterilization using saturated steam, the ZDA-M3 "exceeded expectations" in disinfecting a high level of biomedical waste at the North American test pilot site, he said.

"This test tells us that we have provided access to a real breakthrough in infectious medical waste treatment by bringing the `Z' machine to the United States," Mercer said. "It also reinforces our belief that Aegis is on the leading edge in technological advancements in this area."

The mobile, on-site ZDA-M3 unit shreds and grinds a hospital's medical waste in an enclosed chamber to create a homogeneous waste stream while steam is continuously fed into the machine. It can handle up to 700 pounds of waste per hour.

It disinfects waste with pressurized steam heated to about 320 degrees Fahrenheit for at least 30 minutes. Air and excess steam are processed through an activated carbon filter above the sterilization chamber. …
