AbstractThe CHEM-FREE project proposes

development of a process control instrument to integrate and optimise three well known physical water treatment

devices: fibre filter, ultrasound and UV-C. This is a Cooperative Research Project in the EU 6th Framework

Programme's Horizontal Research Activities involving 4 SMEs: LG Sound (The Netherlands), TB Hauer (Austria),

Drema (The Netherlands) & Limnos (Slovenia) and 3 Universities: University of Natural Resources and Applied Life

Sciences Vienna (BOKU), Institute of Sanitary Engineering and Water Pollution Control (Austria), University of

Portsmouth, School of Biological Sciences (UK) and University of Catania, Department of Agricultural Engineering,

Hydraulics division (Italy).

Both lab-scale and pilot-scale research and validation are performed to combine,

arrange and steer efficiency of physical and biological processes. The resulting integrated technology must combine

the economic and ecological advantages of all the individual devices to achieve targeted application in specific water

qualities without the use of chemicals.

Lab-scale experiments regarding removal of algae result in a better

understanding of the principal removal mechanisms to decrease the contamination for the applications using a) the

individual devices and b) their combinations to determine the optimal operational parameters. Our main results will

be presented.

The optimal integration and control of fibre filters, ultrasound devices, and UV-C sets will result

in chemical-free water treatment enabling ecologically prevention of algae, prevention of biofilm growth on walls, in

pipelines, on fittings and in containers and completely new solutions for sensitive water treatment systems where

chemicals are an unsatisfying solution like drinking water production from surface waters, groundwater recharge,

etc.
