Develop process engineering solutions that address identified performance and capacity constraints, to meet growth and compliance drivers, and improve treatment reliability.
Support opportunities to improve process integration, resource recovery, treatment efficiency and whole‐of‐plant performance while optimising investment outcomes for customers.
