Using principles of Digital Holographic Microscopy we developed a device that is able to digitally reconstruct the objects from a recorded hologram. This technology enables said device to monitor volumes with order of magnitudes (200x) greater than with traditional microscopes. A bespoke recognition algorithm enables the instrument to classify the images from the reconstructed objects according to digital information using a previously recorded object database. The process enables the user to identify different kinds of algae, worms and other objects in the water.

Taking the above capabilities to the next level, our consortium developed and tested the device into a modular industrial measurement system called “WaterScope”. WaterScope can achieve large water and energy savings as well as considerably decrease the risk of environmental contamination. Based on this automatic measurement capability, Waterscope introduces a new, conditional based maintenance technology within the water filtering process in drinking water production. The occurrence of higher order organisms (worms) that proliferate on the biofilm on a given filter surface, - efficiently detected by WaterScope – is an indicator that the filter needs cleaning. With Waterscope providing real time information on contamination levels of the filter, the backwash cleaning of the filters can be reduced, thus reducing water usage all the while maintaining water quality levels as prescribed by the Water Quality Directive.
