Design and Specifications

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.
