Instrumentation. Since the systems are intended to be
run on a batch basis, manual control of treatment unit
operations is recommended. Excessive automation should be
avoided. Any automation provided must have full manual backup.
Automatic backwash controls on filtration units and automatic
start-stop control of polymer feed systems on sensing flow to a
DAF/IAF unit are recommended. pH monitoring and automatic
control for chemicals addition are also recommended. On direct
discharge systems consider provision for automatic recycles of
effluent to a LET if oil is detected at higher than permissible
concentrations. Instrumentation should be provided to monitor
influent and effluent flow and key effluent quality parameters.
Monitoring instrumentation for facilities discharging to
navigable waters should be provided in duplicate for 100 percent
redundancy. Suggested parameter monitoring guidelines are
presented in Table 16.
