Wastewater optimisation provides cost savings
Advanced RTC control modules to provide substantial savings in operational costs
The HACH LANGE optimisation system combines process measurement technology with advanced RTC control modules to provide substantial savings in operational costs, whilst maintaining compliance with consent values.
In combination with HACH LANGE sensors, Nutrient Removal and Sludge Treatment Processes can now be easily optimised in order to achieve savings in aeration energy and chemical consumption, even on small waste water treatment facilities.
As technology advances, new opportunities materialise from the latest sensors coupled with a new breed of real-time controllers. Improvements in the accuracy and reliability of sensors, coupled with a new facility providing information about the sensors' performance, in addition to the measurement itself, means that real-time control (RTC) has become very reliable.
In recent years, improvements in sensor technology have focused on greater resolution and accuracy in combination with longer intervals between calibration or service. However, in order for an RTC system to operate effectively it is also necessary for sensors and analysers to be able to provide information on the quality of the signal and the service status.
HACH LANGE provides RTC control modules with a continuous indication of a sensor's status so that if pre-determined conditions occur (sensor failure, outside calibration, service overdue, drift etc) the RTC automatically adopts an alternative control strategy, which might be a typical weekly and diurnal flow profile that has been stored in the system's memory.
In addition to the stand-alone modules mentioned above, it is also possible to combine different RTC modules to optimise an entire plant. Termed an 'enterprise solution' this activity involves a review of the plant as a whole and the creation of customised specifications for the application of different control modules for nitrification, sludge retention time, methanol dosing, and/or chemical phosphate removal to achieve the best overall performance.
