Heavy Metal
Contamination Removal
from Industrial Wastewater
Heavy
Metal Removal Invention Surprises Treatment Operators!
|
A new chemical blend
named PELLU™ works so well for heavy metal removal from
waste water that it seems impossible: faster
reaction times, removal of 21 identified heavy metals in
one pass, and reduced sludge volumes. The metals include copper (Cu),
nickel (Ni), zinc (Zn,
chrome (Cr), and cadmium (Cd). Complicated treatment
routines with multiple chemicals are eliminated. Wastes
can be mixed, with no need to separate waste streams. A
bonus is the elimination of the common sulfur
smell generated
by other processes.

PELLU treatment
|
| The patent-pending PELLU™ process,
now available from Wastech, reduces treatment
costs, meets or betters discharge limits, and lowers the
risk of discharge violations. With more predictable
treatment results, automation becomes possible, and
company boards of directors can view the waste treatment
process with confidence. |
 The PELLU
Process
PELLU™ chemicals are key
to the process. Even the presence of metal complex or
interfering agents (such as ammonia, sulfates, soaps,
etc.) does not reduce the effectiveness of the PELLU
process in bringing metal levels to below compliance
discharge limits in a single pass. The PELLU process
does so instantaneously and without multiple pH
adjustments. Sludge volume is reduced, and sludge is easier to dewater.
Even chrome waste is reduced to total chrome below
discharge limits in one pass. Low metal wastes can be
removed to ppb levels.
PELLU chemicals compete
with commodity solutions such as caustic soda,
ferric chloride, ferrous sulfate, lime and acid
additives, or proprietary metal grabbers. The PELLU
solution is more cost effective, provides better
results, lowers operator costs, requires fewer tanks,
and simplifies hardware.
For the first time, small
waste generators can treat heavy metal waste streams
onsite, lowering hauling charges dramatically.
Packaged batch and continuous heavy metal treatment
systems available from Wastech make batches as small
as 50 gallons economical. Please see the following:
