The role of faecal coliforms in water quality assessment
The paper aims to evaluate the role of faecal coliforms in assessment of water quality. The study was conducted on the Neretva River in Bosnia and Herzegovina. The sampling was performed bimonthly, over 12 months at seven selected sites. APHA (1995) methods were used. The raw data of temperature, pH, conductivity, oxygen saturation, nitrogen, total phosphorus, and faecal coliforms were transfor...
متن کاملRemoval of Total Coliforms, Thermotolerant Coliforms, and Helminth Eggs in Swine Production Wastewater Treated in Anaerobic and Aerobic Reactors
The present work evaluated the performance of two treatment systems in reducing indicators of biological contamination in swine production wastewater. System I consisted of two upflow anaerobic sludge blanket (UASB) reactors, with 510 and 209 L in volume, being serially arranged. System II consisted of a UASB reactor, anaerobic filter, trickling filter, and decanter, being also organized in ser...
متن کاملColiforms from hides and meat.
Coliform tests were performed on 85 hide and 75 meat samples. IMViC reactions were determined on isolates from positive confirmed and fecal tests, and strains other than Escherichia coli were identified. Strains typed as Aerobacter aerogenes types I and II were identified as Enterobacter cloacae (51.4%), Klebsiella pneumoniae (21.5%), Enterobacter aerogenes (15%), and Enterobacter liquefaciens,...
متن کاملInjured coliforms in drinking water.
Coliforms were enumerated by using m-Endo agar LES and m-T7 agar in 102 routine samples of drinking water from three New England community water systems to investigate the occurrence and significance of injured coliforms. Samples included water collected immediately after conventional treatment, during the backwash cycle, at various points in the distribution system, and 1 week after the break ...
متن کاملRunoff transport of faecal coliforms and phosphorus released from manure in grass buffer conditions.
AIMS To test the hypothesis that faecal coliform (FC) and phosphorus (P) are transported similarly in surface runoff through the vegetative filter strip after being released from land-applied manure. METHODS AND RESULTS The Hagerstown soil was packed into boxes that were 10 cm deep, 30 cm wide and 100, 200 or 300 cm long. Grass was grown in boxes prior experiments. Same-length boxes were plac...
