Feedforward
and feedback control of
nitrogen and/or phosphorous removal plants using on line
analysis and automated control is now a possibility. Design
and operation of nitrogen removal strategies can be optimized
with real time measurement of parameters such as:
|
Daily
trend without using
feedforward control |
| Feedforward
control can improve treatment efficiency and also significantly
reduce running costs Control of F:M ratios , greater control
over aeration zones, and reduction of sludge bulking in final
clarifier are all key factors. |

feedforward control |
| Oxidation

BOD at the inlet with in-situ DO, NH4 and NO3 measurement |

| Increasing
use of sophisticated software models such as GPSx highlights
the need for improved data. A model is only as good as the
data fed into it. On-Line sensors can generate a dynamic
, 24 hour picture of inputs and outputs. |
