APTsorb Data Sheet
PRODUCT
DATA
SHEET
APTsorb
is
an
innovative,
environmentally
friendly
sorption
media
for
dissolved
heavy
metals.
It
is
made
of
physically,
thermally,
and
chemically
modified
reed--sedge
peat
harvested
from
the
abundant
reserves
of
North
America.
It
capitalizes
on
the
known
sorption
mechanisms
and
capacities
of
natural
peat
while
improving
on
those
qualities
that
have
limited
peat’s
use
in
wastewater
treatment
in
the
past.
APTsorb
is
a
low--cost
alternative
to
traditional
resins
and
excels
in
applications
such
as
polishing
prior
to
discharge,
storm
water
treatment,
and
waste
waters
with
low
pHs.
