Abstract

Large diameter transmission mains pumping raw water experience capacity loss during the summer months due to the growth of biofilm. The loss of capacity impacts power costs at a time when power is obtained at a premium. Biofilm growth varies with the seasons and varies along the length of the pipeline. Biofilm growth and decay directly impacts the friction factors. Future design work should consider a seasonal friction factor rather than an aged friction factor over time.The method of controlling biofilm is with the application of chloramines at the lake pump stations. This study compares the difference between little to no chloramines application to increased chloramine dosages as related to the friction factor. Proper chloramines application retards the growth of biofilm and is cost effective.
