ROOM 20-A
Environmental Engineering Research Laboratory
Dr.
Dempsey's lab
contains a zeta
meter, streaming-current
detector, carbon
analyzer, and
several small
items
including turbidimeters, conductivity
meter, and pH meters. Wet chemistry dominates in this lab.
Titrations, extractions, and jar-testing are common sights. The
lab is a center for field-work
and for experiments that will use equipment at other campus locations

Kevin Choi (on left)
works on an AWWARF-sponsored project dealing with the use of
novel coagulants in water treatment. In this picture, he's using
a micro-buret to dose concentrated coagulants into raw water
from Altoona, PA. Kevin plans to study in-line coagulation for
membrane filtration for his Ph.D. dissertation.

Byong-Hun Jeon is shown
at the glove-box in Room 9A.
He runs his set-ups from Room 20A. His Ph.D. dissertation
will deal with sorption of Fe(ll) by ferric oxide minerals,
and careful anoxic conditions are necessary for this task.
Byong-Hun already completed his M.S. at Penn State, focusing
on the characteristics of iron oxide minerals that are produced
during treatment of acid mine drainage. |
| Je-Hun Jang spends most
of his research hours at the nuclear reactor building, where
he is building a Mossbauer spectrometer that will be used to
analyze labile Fe(ll)Fe(lll) materials. Room 20A is his center
for set-ups and for analysis. |

Ben Paksuchon is analyzing water
samples for alkalinity,
hot-peroxide acidity, sulfate, pH, TSS, and total extractable
Al, Fe, and Mn. Ben and about ten other undergraduate and
graduate students are evaluating the quality of rivers and
streams across Pennsylvania. The goal is to determine the
best way to get these streams to a fishable-swimmable condition. |
