2 Deposits on Membranes Biofouling - Frequency: Present in ~90% autopsies as Fouling factor. Main Fouling in ~30% of the Autopsies Specially in surface water, tertiary plants and desal. plants Biofouling 28% Biofouling Oxidation Metal Clay Scales Abrasion 2

3 If fouling would happened Fouling Biofouling Pressure H 2 O Increase of the pressure energy Feed H 2 O H 2 O H 2 O RO membrane Permeate Decrease of Permeate 16/11/2018 3

4 Problems in membranes Biofilm development on the membranes leads to: High differential pressure across the membrane High energy cost to maintain permeate flow in KWh/m 3 Reduction of membrane lifetime by physical damage Frequent CIP cleanings High operational cost 16/11/2018 4

5 Total Bacterial Count in water does not correlate to Biofilm growth on membrane. Comparison of results after 14 days Total bacterial count in CFU/ml 1,E days 1,E+06 1,E+04 7 days 14 days 7 days 1,E+02 1,E+00 CFU in water CFU in biofilm CFU does not correlate with the expected biofilm amount! Need Control Method to measure the Biofilm on the membranes during operation. 16/11/2018 5

6 The Objectives: 1. Having an efficient Biofilm control agent 100% compatible with Membrane systems 2. Monitor real time the Biofouling growth in the plants in order to manage/optimize the dosage of chemicals. 6

7 The Solution Package: New Biofilm control agent for Membrane systems Effective Monitoring of Biofilm and Scaling Dosage Automatisation 7
