PELLU Batch Treatment Process
for Heavy Metal Removal from Wastewater
The PELLU process of heavy metal removal
from wastewater can be a batch
treatment process or a
continuous treatment process. Typical applications for the
PELLU batch treatment are sporadic, low volume generators with very
high level metal concentrations. Laboratory and/or
pilot studies will establish the required combination and dosing of
PELLU chemicals.

Typical PELLU Batch Treatment
System
- Capacity: 1,000-gallon tank equipped with a high speed mixer.
- Control
hardware: Fully automated with level sensors in treatment
tank.
- Process control: At
a wastewater level setpoint, as detected by level sensors, the PELLU
chemicals dosing pumps are turned on until a pH setpoint is achieved
in the tank, indicating completion of the reaction. The dosing pumps and
the mixer are then turned off. Time is allowed for total liquid/solids
separation. The resulting high quality clear water can be reused, be
further treated, or dumped to the local municipal sewer. The sludge is pumped either to
a sludge holding tank or to a filter press.
- Throughput time: Very fast.
