This powerpoint presentation begins by providing a brief overview of nitrification in drinking water systems. The study approach is presented, and topics covered include: evaluate impact of pipe corrosion on nitrification
occurrence
in four pipe materials that included PVC, copper, brass, and lead; nitrification effect on water
quality in different pipe materials; TOC creation in different pipe materials; after 3.5 days, complete ammonia loss in
PVC at all pH (6.5-8.5) and phosphate
levels; ammonia loss in brass pipes after 3.5 days stagnation; and, correlation of ammonia loss % vs.
soluble Cu in copper and brass pipes. Presentation conclusions indicate that: selection of pipe materials has a strong
impact on nitrification occurrence;
nitrification in different pipe materials is
high in
Iron, Concrete, PVC, Lead;
medium in
Glass, Galvanized, Brass;
low in
Copper; pH (6.5-8.5) and phosphate (5-1000 ppb)
had no or very small impact on
nitrification in PVC and lead pipes; and,
pH (6.5-8.5) and phosphate (5-1000 ppb)
can affect nitrification level in brass pipes
(probably copper) by affecting corrosion. Includes figures.
