The bacterial community significantly promotes cast iron corrosion in reclaimed wastewater distribution systems.

ABSTRACT:

Background

Currently, the effect of the bacterial community on cast iron corrosion process does not reach consensus. Moreover, some studies have produced contrasting results, suggesting that bacteria can either accelerate or inhibit corrosion.

Results

The long-term effects of the bacterial community on cast iron corrosion in reclaimed wastewater distribution systems were investigated from both spatial (yellow layer vs. black layer) and temporal (1-year dynamic process) dimensions of the iron coupon-reclaimed wastewater microcosm using high-throughput sequencing and flow cytometry approaches. Cast iron coupons in the NON_disinfection and UV_disinfection reactors suffered more severe corrosion than did those in the NaClO_disinfection reactor. The
