In-Depth Information
ABS's product and has been pushing projects under his permit authority to closely exam-
ine the material. Likewise, the Ohio EPA SWIF program that funds stormwater improve-
ment products has informed application parties that proposals that include Osorb-based
materials to improve water quality will be favorably reviewed.
While a macro effort to introduce a product is important, it is each individual response
that makes or breaks the introduction of any product. John Veney is a resident who lives
next door to the twin-chamber Osorb stormwater system built at the College of Wooster
in 2011. This system replaced a rather ugly ditch, which had gathered rainwater from sev-
eral locations for years and was well known for overlowing into the street and being a
low-grade eyesore. ABS was not aware of how bad the situation had been until Veney
sent letters to both the College of Wooster and ABSMaterials expressing gratitude for the
Osorb stormwater system addition to the street and for solving this long-standing prob-
lem, which included a regular looding into his garage. He also noted the amazing native
plant garden that had replaced the former mud trench and asked to be updated on how
the system was working. Veney, a retiree, has since become a reference and public advocate
for systems.
33.9 Introduction in Laboratory
The following section provides a brief summary of research projects on the development
of new bioretention ilter media to enhance pollutant removal by adding Osorb nanomate-
rials in bioretention systems. The research results presented here are based on work sup-
ported by the NSF SBIR program (grant no. 1113260).
33.10 Development of Osorb-Metal Composites
Five nanoscale zerovalent metals including aluminum (Al
0
), iron (Fe
0
), magnesium (Mg
0
),
nickel (Ni
0
), and zinc (Zn
0
) were used to create Osorb-metal composites. Osorb was used
to entrap the metals to create composites. Five different Osorb-metal composites (Figure
33.3) were created by adding each metal during the synthesis of the Osorb to embed each
metal within the Osorb matrix. Manufacturing was accomplished by adding 10% w/w
of each metal during the manufacture of the Osorb. Each Osorb-metal composite was
Al-Osorb
Fe-Osorb
Mg-Osorb
Ni-Osorb
Zn-Osorb
