Fig. 3: Chemical composition of the water: total nitrogen.
From: Pilot-scale drinking water distribution system to study water quality changes during transport
Results for (a), non-purgeable organic carbon (NPOC) (b), Cl- (c), NO3- (d), SO42- (e), Na+ (f), K+ (g), Mg2+ (h), and Ca2+ (i). Every day, one sample from every loop was measured during 7 days. For the NPOC measurements, technical triplicates were measured and averaged. Day 0 corresponds to the measurements after the cleaning of the pilot, prior to introducing the water in the loops. Loop 1 = red; loop 2 = green; loop 3 = blue.
