Intermittent filtration of wastewater—removal of fecal coliforms and fecal streptococci

Water Research, 2002
Removal of fecal coliforms and fecal streptococci was monitored over a period of 13 months in 14 buried pilot scale filters, treating septic tank effluent. The effects of grain size, hydraulic dosing rate and distribution method were investigated. Two different natural sands (sorted sand and unsorted sand) and three different types of light weight ...

Load of coliforms and fecal coliforms in dairy desserts in Aswan City

International Journal of Life Science Research Archive, 2022
The dairy desserts are of wide popularity and variety. Also microbiological safety and quality is lack. Seventy five samples of dairy dessert consumed in Aswan City were collected and analyzed for coliforms, fecal coliforms, and E.coli counts. The results revealed that 14 (56%), 9 (36%) and 5(20%) of examined dairy desserts Bellilah, Custard and Om-Ali

Extended Acid Digestion for Inactivation of Fecal Coliforms

Water Environment Research, 2006
The objective of this research was to establish a correlation between inactivation of fecal coliforms caused by organic acids in their un‐ionized form in batch acid digesters and semicontinuously fed acid digesters at both mesophilic (38°C) and low‐mesophilic (24°C) temperatures. Batch acid digesters achieved a U.S.

Agar Medium for Enumeration of Fecal Coliforms

Journal of Food Science, 1992
ABSTRACT Spread‐inoculated plates of fecal‐coliform agar (FCA) were pre‐incubated 2 hr at 35°C, and then transferred to 44.5°C for 22 hr. Fecal coliforms on FCA produce acids and CO 2 , which react with bromocresol purple and calcium lactate to form yellow to yellow‐green ...

Coliforms, fecal coliforms, and fecal streptococci as indicators of water pollution

Water, Air, and Soil Pollution, 1973
The presence and survival of coliforms, fecal coliforms, and fecal streptococci were studied in sewage treatment plants, heavily polluted rivers, a lake, and other drinking water sources. In all cases the fecal streptococci were generally more resistant to the natural water environment and to purification processes than the other indicator organisms ...
