Résumé :
|
The aims of ths study was to investigate the inhibition of biofilm formation on stainless steel (SS) and galvanized mild steel (MS) in chlorine and chlorine-monochloramine treated waters. The methods and the results are presented. The inability of bacteria to grow on SS and MS was observed only when 0.35mg1-1 residual monochloramine was maintained throughout the system. This demonstrates the inability of chlorine alone to inhibit bacterial growth and suggests a combination of chlorine and monochloramine as a more effective treatment for drinking water, especially for rural communities with very poor source waters in Africa.
