The former set limits with respect to the number of total coliforms in the product.
Mixing harvested rainwater with groundwater resulted in higher phosphates and total coliforms.
Measurements of total solids, organic matter, total coliforms, pH and electrical conductivity were also made.
Total coliforms were detected in 84.4 95.8% of the collected rainwater samples in the six tanks.
Further, at optimum conditions high removals of phosphate (79%), suspended solids (84%), BOD (78%) and total coliforms (99.7%) were obtained.
During digestion, total coliforms were reduced by 99.1%, E. coli by 98.5%, and chemical oxygen demand (COD) by 93.6%.
Natural water sources with wild strains of Escherichia coli, total coliforms, Enterococcus spp. and Clostridium perfringens (including spores) were studied.
After HSF operation for 10 days, 97% reduction in E. coli, total coliforms and turbidity was evidenced.
The MWW contained varying concentrations of total coliforms (TC), fecal coliforms (FC), Escherichia coli, and fecal streptococci (FS).
Complete inactivation of wild total coliforms, E. coli and Enterococcus sp. in municipal wastewater treatment plant secondary effluents took place after 80 min.
While the average values for total coliforms and E. coli were 5 × 104 and 5 × 102; 1.2 × 104 and 7.2 × 101 CFU/mL, for the respective sampling periods.
