Port Adelaide Re-lift Pump Station (PARPS) serves as the inlet works and screening for the Bolivar High Salinity Plant. The plant services and accepts wastewater from approximately 30,000 connections equating to approximately 22.5 ML/d. The PARPS is a critical infrastructure to the ongoing operation of the Greater Adelaide sewer network.
Prior to the upgrade, foul air to be treated was approximately three times higher than what the original system was designed for when installed in 2004. Whilst operational changes and improvements were done, the system was overloaded and affected a large surrounding population when discharging ineffectively-treated foul air.
Upgrading the odour-control system was a high priority.
Waternish implemented its internal process expertise to develop partnerships with world-leading technology suppliers and offer an engineered solution, which significantly improved the quality of life for local residents.
The Odour Control Facility designed, built and commissioned with internal resources has a capacity of 8,000m3/hour with 99.95% removal at design levels of 700ppm H2S and 500,000 ou. A three-stage process was used and consisted of a bio trickling filter, a biofilter, and an activated carbon filter (with both virgin and impregnated carbon).
In addition, a significant amount of collection ductwork was installed through the pump station, screening and grit removal handling areas. Access platforms and walkways, chemical dosing systems and drainage pump stations were also installed.
