Seminar Details
More efficient ways of aerating activated sludge are highly sought after by water companies who traditionally adopt an un-optimised approach to controlling oxygen, often resulting in over-aeration or under-aeration. Microbial tests are performed off-line in laboratories with up to ten days delay in results. We will discuss:
*Value in terms of cost, energy and carbon emissions savings of improved management of microbial processes in Wastewater purification.
*Advantages of on-line measurement in real time
*Potential for advanced process control
*A novel method of measuring microbial activity:
Bactest's solution, Shepherd, is a true in-situ, real time instrument which samples the activated sludge at regular intervals and measures microbial activity. Activity is quantified as a function of pressure changes due to gaseous exchange caused by the metabolic processes of the microbes within a closed vessel. The system maintains optimal conditions for growth and measures pressure via barrier protected sensors, enhanced for speed by a highly efficient mixing system. We aim to reduce water companie's energy usage and carbon emissions by up to 20%
Unlike conventional Dissolved Oxygen probes acting at an arbitrary set point, Shepherd measures the biological activity in real time facilitating sophisticated decision making for dynamic process control. Shepherd can measure both positive and negative pressure transients and can be applied to different gas exchange processes, not just Oxygen usage or Carbon Dioxide production.
We will communicate collaboration opportunities.
Attendees should be:
Those from the wastewater industry with a desire to reduce energy and carbon emissions.
Potential commercial or academic partners.
