Bioremediation – the use of certain biological agents to remove or neutralize contaminants from polluted soil or water – is a rapidly advancing field and the technology has been applied successfully to remediate many contaminated sites. Effective monitoring of biological processes is a necessary component of any bioremediation application.Currently, the influence of the remediation process is monitored by taking samples from contaminated sites and analysing them remotely, which takes a lot of time, and costs significant amounts of money. By integrating online, real time on-the-field monitoring and control systems into the remediation process, the overall time and cost of remediation can be decreased significantly.The proposed project intends to build on recent advancements in the fields of sensor and low-cost wireless technology to address the need of a system for continuous monitoring the bioremediation processes. The aim of the project is to develop a flexible and expandable, low cost online system for detecting subsurface microbial events allowing autonomous control and remote adjustment of the remediation process.The project objectives include the development of• new generation of biosensors with ultra-low power consumption for the detection of aromatic compounds• low-cost, self-sustaining and expandable wireless communication system• a treatment unit with autonomous control and remote adjustmentand the integration of the obtained data with pre-existing data analysis systems.SMEs involved in bioremediation will possess a low-cost system enabling the continuous monitoring, autonomous control and remote adjustment of the microbial processes at the contaminated sites, which reduces operational costs and shortens response time.
