Bioremediation testing at PSAC II

The Public Safety Answering Center (PSAC II) Project in the Bronx is a closed access and secure facility that runs continuously without downtime. Limited access to exterior views and natural daylight makes the proposed AMP system an ideal application to improve the quality of well being for building occupants in addition to demonstrating the air cleaning capacity of this proposed system and the potential for reduction of the energy consumption profile. The installation and demonstration of a various range of air cleaning hydroponics plantings
will be tested within the atrium. PSAC II is an ideal first New York State test bed for this technology because it raises two other important issues: firstly, the building has security requirements that require the exterior air intake to be ‘locked down’ during an emergency, therefore the AMP system could create safe, secure zones of ‘fresher’ air in an emergency; secondly, the proposed site in the Bronx is an example of seriously compromised air quality in and around contemporary cities which is often even more polluted during certain times of the year
than indoor air, making internal production of ‘fresh air’ even more urgent for urban conditions where public health is seriously compromised by deteriorating air quality in general.

The assembly PSAC II consists of a fan-assisted plenum that pulls soiled air from the atrium through a plant filtration comprising the planted root environment (surrounded by activated carbon, expanded clay, foamed glass and ultraviolet light) whereby it is purified, humidified, and freed of microbes before it is connected to the duct system servicing each individual zone. The proposed innovation by this biofiltration and remediation assembly is to use biological means to condition air, such that mechanical HVAC systems are streamlined and
continuously cleanse through the regeneration of purified air.

Following completion of initial environmental testing of the lab-scale module in Phase I at the Aerosol Research Lab (ARL) at RPI, additional environmental testing will be undertaken at MRC 311 at RPI and a full battery of demonstration and environmental testing will be undertaken on a building scale panel under real-world conditions. This panel will also be assessed, demonstrated, and adapted for the installation of the AMP system into an atrium within the PSAC II project. This first implementation of the technology represents an ideal test
bed for further installations across New York State and within global markets by SOM and others.
