PREDICTABILITY AND CONSISTENCY SAVES YOU TIME AND MONEY
Producing biostable and safe drinking Water for consumption is essential for Water utilities. In industry being in control of the process Water quality reduces the potential for production downtime and eliminates the costs associated with fouled products due to introduction of sub-standard Water quality in the production process.
TAKE CONTROL OF THE WHOLE WATER PRODUCTION CHAIN
The real value of monitoring microbiological water quality lies in the early detection of change from the normal operating conditions. Therefore the starting point for gaining the full potential of the Bactiquant technology is to establish baselines for normal operation at Critical Control Points. The Bactiquant data handling software is then used to establish operational thresholds, based on historic data and simple statistical calculations (ISO 11462-1). The software provides the operator with a rapid and comprehensive overview of water microbiological quality and easily interpretable results.
EARLY DETECTION OF DEVIATIONS
The aim of our utility and industry customers is to produce Water of a uniform and high quality.The keyword is process control. The advantage over other methods of quality control such as "inspection" is that emphasis is on early detection and prevention of problems, rather than correction of problems after they have occurred and result in Water of sub-standard quality. Our customers produce water of a high quality by monitoring and controlling water quality in the whole production chain from raw water through treatment processes and distribution to the end use.
Example of critical control points for a Water utility treatment process:
MICROBIOLOGICAL MONITORING AND CONTROL IN THE PROCESS
The concept is simple: 1) Identify Critical Control Points 2) Establish baselines at each point 3) Stabilize baselines by eliminating assignable sources of variation 4) Monitor and control the ongoing process. The graph below shows data from a water utility customer. The Critical Control Point is the outlet from a Water Plant and the data calculations and graph were generated by Mycometer software. Initially the process was not in control. The operator of the Water utility tracked the source of variation to an inefficient filter flushing protocol. The filter flushing protocol was changed and the baseline stabilized.
OUR CUSTOMERS ARE IN CONTROL
Our customers use the data handling software to produce consistent and predictable Water quality. When they have a stabilized baseline they are in control and they can deliver Water of a uniform and high quality. Improvements to the process are a continuous task and the data handling system is essential to sustain improvements and keep reducing variations and mistakes. Actions to improve Water quality include establishing standard operating procedures, training staff and introduce changes to the system. The baselines can be used to evaluate the changes to a process when new procedures are implemented or new activites are introduced.
STATISTICAL PROCESS CONTROL (SPC) AND REACTION PLANS
SPC is Applied in order to monitor and control a process. SPC can be Applied to any process where the product conformity can be measured. Key tools in SPC includes control charts and a focus on continuous improvement. In order to gain the full potential of process monitoring and control, it is important to establish a reaction plan that describes what you do if the result is above the control limit. A typical reaction plan includes, retesting, establishing a trouble-shooting guide and protocols for adjusting the process.
