JIPL is exhibiting at New Zealand’s Water Expo on 19 – 21 September 2018. Mike Smith from INVENT Pacific, will be with us on Stand 91 on Thursday 20th September. Mike is an aeration and mixing expert and has recently brought the INVENT ALPHAMETER® into New Zealand, currently on hire by a major council organisation. The ALPHAMETER® is an off-gas measuring device and is used worldwide for direct aeration control and process monitoring. This an extremely useful tool for the monitoring of both the actual oxygen uptake (biological activity) and aeration system performance of a plant.
The ALPHAMETER® is available for hire so please contact us about hiring opportunities.
The INVENT ALPHAMETER®
The ALPHAMETER® represents “state of the art” monitoring of process parameters. The ability to develop real-time OUR (Oxygen Uptake Rate) data allows quantifying diurnal/seasonal variation in process loadings and demands, detects process inhibitions and provides vital information on plant bottlenecks or process imbalances.
The ALPHAMETER® allows a quantitative approach to aeration system control by providing real-time measurement of process oxygen demand (OUR) and parameters affecting oxygen transfer. Combined knowledge of the amount of oxygen required to fulfil process needs and all the parameters affecting oxygen transfer allows the ALPHAMETER® to determine the exact amount of air required to meet both biological process and operator control needs, thus eliminating all trial and error, iterative and tuning based control algorithms.
This direct approach greatly reduces aeration control response time allowing more accurate control. This results in increased system stability and significant energy savings.
Traditionally, aeration system control and monitoring have been based on liquid phase measurement of parameters related to aeration system performance. Many of these parameters have been used as indicators of biological process and aeration system performance, but none have been able to provide accurate, real-time measurement of process oxygen demands and aeration equipment performance.
