Chemical kill system commissioned for N.Y. BSL-3 lab

Officials with Practical Applications, Inc. announced that they have commissioned their chemical kill system to treat waste water for the Center for Medical Science BSL-3 laboratory in Albany, New York.

The treatment system uses chemical dosing to treat lab waste water by killing bacteria, viruses and spores that may be discharged from sinks, showers and washers. During the commissioning of the system, a modified and deactivated strain of anthrax was destroyed, according to company officials.

The system is comprised of two batch waste water treatment tanks for use as secondary containment. The system also uses two mixers, four reagent pumps, two chemical storage tanks, probes, a residual chlorine analyzer and an effluent electromagnetic flow meter.

The control panel, which is mounted outside the containment area, provides all operator interactions and the pumping station for the chlorine analyzer, officials said.

The system, which is capable of treating up to 28,000 gallons of waste water per day, is designed to function automatically.

Waste water is fed to the treatment tanks via a vacuum collection system that is gravity drained. Once the batch tank reaches specified levels, the chemical kill system enters treatment mode. Waste water is then mixed with chemical reagents until safe ORP and pH levels are reached. The set points are then maintained for a specific dwell time before the contents are discharged to the sewer.
