Was diese Zeichnung zeigt
Die dahinterstehenden Entscheidungen verstehen.
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.
