The process de-nitrification can be carried out by suspended growth and attached growth systems. The plug flow type of activated sludge system is commonly used. The flow diagram for the removal of biological nitrogen is depicted in Fig. 57.16.
Learn MoreThe process flow diagram (PFD) is a visual representation of the mass and energy balance. The PFD treats unit operations more simply than the P&ID (see "Piping and instrumentation diagram" section). Unit operations are shown using ISO or British Standard (BS) P&ID symbols or sometimes as simple blocks; pumps are shown, as are the main …
Learn MoreA Process Flow Diagram - PFD - (or System Flow Diagram - SFD) shows the relations between major components in a system. PFD also tabulate process design values for components in different operating modes, typical minimum, normal and maximum. A PFD does not show minor components, piping systems, piping ratings and designations.
