PELLU Wastewater Metal Removal Process:
Frequently Asked Questions
|
|
Q. |
What is the PELLU
Process? |
|
A. |
The PELLU Process is a highly
efficient, cost-effective process for the treatment of "real-world"
metal-laden waste solutions; wastewater matrix that is complexed/chelated
with sequestering agents; high in Biochemical Oxygen Demands (BODs)
and Chemical Oxygen Demands (CODs). The process which removes all heavy
metals totally encompasses the concepts of pollution prevention, waste
minimization and resource recycle. |
|
Q. |
What superior
performance is the PELLU process claiming over present metal treatment
processes? |
|
A. |
|
The PELLU Process is claiming superior performance
in all aspects of process control in treating real time metal-laden
water solutions: |
|
1. |
The process is not pH-sensitive. All metals in
a multi-metal waste solution are removed at one pH treatment cycle. |
|
2. |
The process is highly efficient even in the presence
of interfering agents (EDTA, chelating/sequestering agents). |
|
3. |
The process effectively treats metal-laden solutions
high in Biochemical Oxygen Demands (BODs) and Chemical Oxygen Demands
(CODs). |
|
4. |
The process can also remove some ranges of organics
(e.g. Phenols), colors and odors. |
|
5. |
The clarifier retention time is
drastically reduced
from 5-30 minutes to less than 1 minute, resulting in a highly compact
treatment unit with a very small footprint. |
|
Q. |
What are the
typical areas of applications? To what industries do the products
apply? |
|
A. |
The PELLU Process can be used by all
generators/handlers of metal-laden wastewater. |
|
Q. |
How cost
effective is the process? |
|
A. |
The PELLU Process is cost competitive
with present processes on the market. |
|
Q. |
I have a
conventional wastewater treatment systems unit (reaction-mix,
flocculation/ coagulation and clarifier chambers). What is my
capital equipment cost if I want to change over to the PELLU
chemicals? |
|
A. |
The PELLU chemicals are highly
adaptable to present conventional systems unit with little or no
modifications. This process simply makes your unit cheaper and more
efficient to run. |
|
Q. |
I need a
treatment system in my facility. Does the PELLU Process come with a
systems unit? |
|
A. |
The PELLU systems unit is a highly
compact modular unit with a very small footprint. The unit can be
batch or continuous; manual; semi- or fully automated. |
|
Q. |
Can the process
treat high color metal-complexed dyeing solutions? |
|
A. |
The process can effectively remove the
metals and color from a dyeing solution all in one treatment cycle. |
|
Q. |
How does the
process handle chelated hexavalent chromium plating waste solutions? |
|
A. |
The PELLU Process eliminates the
noxious gases intermediate step of reducing Cr(VI) to Cr(III). Hexavalent chromium is maximally
removed to compliance level. |
|
Q. |
I want to
remove my metals from my waste solutions. How can I use the PELLU
Process? |
|
A. |
The process can be integrated onto a
metal recovery platform either at the front-end in a precipitation
step or at the end of the platform in a sludge recovery method. |
|
Q. |
Does the PELLU
process handle free/total metal-complexed cyanide wastewater? |
|
A. |
The PELLU process can effectively
handle both free and total cyanide metal-complexed waste solutions. |
