The scenario
A water treatment plant needs a P&ID for raw water intake and pre-treatment stages including coagulation, flocculation, clarification, and filtration.
What is in this drawing
Read the decisions behind it.
01
Used a flow control loop on raw water feed with FT/FIC and a diaphragm-actuated control valve.
02
Modeled clarifier and flocculation basins as atmospheric tanks and included a rapid sand filter.
03
Added a second flow control loop on filter effluent to maintain downstream flow.
Use for designing or documenting conventional surface water treatment pre-treatment systems with chemical dosing and filtration.
