Under this design, build and operate (DBO) contract Murphy delivered a new effluent treatment for the PepsiCo concentrate production facility at Carrigaline in Cork. Our solution treated 200m3 of industrial effluent each day with an average BOD5 concentration of 3,390 mg/l and included facilities for dewatering of solids removed.
The key challenges on this project entailed designing a process solution which reliably treat an influent with high BOD5 levels and variable pH to a standard where it could be discharged to the municipal network and treatment system without any adverse impact.
The solution delivered by Murphy included:
The solution delivered by Murphy achieved 99% BOD5 removal efficiency.
