Process Flow Diagram Water Treatment. These plant designs include a range of key technologies all researched refined and tailored to provide our customers with the ultimate solution in water treatment processes. PFDs are used for visitor information and new employee training.
A conventional sewage treatment plant has the requisite operating units arranged one after another for treatment and final disposal of sewage. The process flow sheet or flow diagram is a graphical representation of the sequence in which various unit operations and unit processes are adopted for treatment of sewage at any sewage treatment plant. PFDs are used for visitor information and new employee training.
The design of process flow sheet involves selection of an appropriate combination of various unit operations and unit processes to achieve a desired degree of contaminant removal.
