DESCRIPTION
The HA1200 Coagulation Control System brings everything you could possibly need to
the table for optimizing coagulant dosing. This controller brings together both Streaming
Current and UV254 measurements in a single platform. Either or both measurements
can be used as part of the control algorithm. If your coagulation is mostly driven by
organics, then utilizing the UV 254 measurement as a primary control for coagulant feed
is recommended, but the addition of the Streaming Current sensor gives you the extra
assurance that the job of charge neutralization is actually getting done. And there is also
an option for feedback control from a UV analyzer post filtration which can be used to
optimize the streaming current setpoint as needed. pH, conductivity, and chlorine
measurements can also be part of the measurement platform as the HydroAct 1200 is
capable of accepting up to 12 parameters.
