Sydney Water: Seawater Desalination Plant Design and Assessment Report

This report details the design and assessment of a seawater desalination plant, addressing key components and processes. It begins with an abstract and background on desalination's importance, followed by a comprehensive design assessment. The assessment includes the design layout of the desalination plant, focusing on intake, pre-treatment, RO system (including ROSA software analysis for optimizing parameters like stages and membrane selection), energy recovery, chemical dosing, and PLC systems. The report also examines the impact of desalination on cuttlefish, proposing mitigation strategies for brine disposal. Furthermore, it discusses the plant's shutdown procedures, particularly reverse osmosis and permeate flush processes. The report concludes with recommendations and references, providing a thorough overview of the plant's design and operational considerations.
