Reducing amount of chemicals in manufacturing and agricultural production, municipal water preparation and filtering, and thus reducing contamination to residents, wildlife, and water sources represents the important social, ecological and technological task. One of possible ways to fulfil this task consists in transition from chemical to non-chemical water treatments, such as the controlled hydrodynamic cavitation, the high frequency electric/DC electric field pulsing or UV lighting for corrosion/microbiological/viscosity control in cooling/heating/osmosis applications. Weak non-chemical treatment is difficult to detect and to characterize by common methods of physicochemical analysis. The technology handled in the E-Spectr project addresses the problem of sensing ultra-weak ionic changes in fluidic media caused by non-chemical treatments (or by ultra-low concentrations of chemicals). This approach represents a new high-resolution sensing technology with applications for material spectroscopy in biology/chemistry, biotechnology, material science, water quality monitoring and robotics. The initial technology was developed in the EU-funded project ASSISI|bf, the launchpad project E-Spectr targets exploitation aspects with the overall objectives: a) to parametrize the excitation spectroscopy device to concrete application areas on the global market; b) to perform necessary certifications and documentation required for market introduction and production; c) to look for potential partners on global biotechnological/energetic market.
