Online wastewater monitoring system using solid state sensor

Water and wastewater monitoring management is a task of paramount importance for the environmental control operations in the framework of the Adaptive Water Management policies enforced by the current EU legislation. Water resources management, on one side, and efficient water/wastewater treatment and control operations, on the other, must be carried-out timely and synergistically for best results. It is well known that conventional field sampling operations condition significantly data reliability from both qualitative and quantitative aspects. To overcome this problem, speditive field analysis, carried-out by the use of low-cost devices with solid-state gas sensors (e-nose), may offer a solution to the sampling, transport and deferred laboratory operations. The proposed devices do not require consumable and may be easily connected to data acquisition network.
