The request
“Draw a chemical dosing and disinfection P&ID with a hypochlorite tank, isolation valve, dosing pump, flow control valve, filter, chlorine contact tank and FT-101/FIC-101 loop.”
Then tryAdd a residual chlorine analyser at the outlet.Change the dosing pump to a standby pair.
What is in this drawing
Read the decisions behind it.
01
Metering pump with diaphragm control valve fail-closed protects against over-dosing
02
Flow indicator controller trims the hypochlorite dosing valve based on line flow
03
Chlorine contact tank provides disinfection contact time before filtered water exits
Use this P&ID as a base for water treatment chemical dosing loops where flow-paced disinfection with a contact tank is required.
