Phosphorus Removal Systems
The ATAC PRS is a phosphorus
reduction system designed to meet
the challenging phosphate consent
standards set by environmental
agencies. This system offers a
cost-effective solution compared
to alternative equipment, providing
substantial savings without
compromising performance.
The ATAC PRS is engineered to treat
final effluent from 2 mg/l down
to 0.5 mg/l as P (phosphorus). Its
design incorporates integral mixing
and flocculation tanks equipped with
variable-speed mixers, ensuring
efficient phosphorus reduction.
With a maximum design flow of
approximately 8-10l/s (29-36m3/
hr), the ATAC PRS can handle varying
flow rates depending on the required
performance. Additionally, the system
can be expanded by attaching a
second ATAC lamella settlement
tank to increase capacity to up to
20l/s. This flexibility makes the ATAC
PRS a versatile solution for different
wastewater treatment plants.
Operation and Control
For effective phosphorus removal, the
ATAC PRS employs a combination of
coagulation, flocculation, and lamella
settlement processes. Ferric, a
coagulant, is dosed via an inline mixer
upstream of the P-Lamella package
plant, allowing for optimal reaction in
the feed pipework. Additional mixing
and flocculation occur in the dedicated
tanks, ensuring the formation of large
ferric flocks that settle effectively.
Effluent from the lamella units flows
over into the central channel and is
discharged.
The mixers in the ATAC PRS are
equipped with variable-speed drives,
allowing operators to manually adjust
the mixer speed at the motor control
centre (MCC). Typically, the first mixer
runs faster than the second mixer in
the tank. This configuration ensures
optimal mixing and promotes efficient
phosphorus reduction.
