The aim of this study was to determine the effect of natural zeolite (commercial preparation with 80% of clinoptilolite) on counts of different physiological groups of bacteria i.e. sulfide-producing, faecal and total coliform, mesophilic aerobic and anaerobic, and thermophilic bacteria in pig slurry. Zeolite was spread daily directly over partially slatted floor in a dose of 0.4 kg/1 m 2 durin...

A survey of the microbiological and chemical quality of water supplies in the Bindura urban and peri-urban area was carried out over a three year period from January 2000 to July 2003. Bindura is the provincial city of Mashonaland Central, situated 88 km from the national capital, Harare. Large-scale farming and mining activities in the area predispose water bodies to eutrophication and chemica...

Grey water from a university facilities building in Cairo, Egypt was analysed for basic wastewater parameters. Mean concentrations were calculated based on grab samples over a 16-month period. Values for chemical oxygen demand (COD) and nutrients exceeded values reported in a number of other studies of grey water, while coliform counts were also high. A submerged membrane bioreactor (SMBR) syst...

In this study ten laboratories in Greece compared the performance of reference method TTC Tergitol 7 Agar (with the additional test of beta-glucuronidase production) with five alternative methods, to detect E. coli in water, in line with European Water Directive recommendations. The samples were prepared by spiking drinking water with sewage effluent following a standard protocol. Chlorinated a...

Coliform bacteria contamination of food and beverages may result from various causes, one which is faecal contamination, leading to serious health issues. Drinking water coliform 50/100 mL has been found be responsible for diarrhea episode. Local regulation determined the cut-off point its within commercial not exceed 3/mL. No such study ever conducted in Ternate. To determine exact value stree...

This three year study compared the decay of the commonly used faecal indicator organisms Escherichia coli, enterococci and coliphage in coastal water and sediment using laboratory based microcosms with that for the pathogens Salmonella typhimurium and S. derby. Results from the laboratory study were validated with in-situ decay rates of faecal coliforms observed at a recreational coastal site f...

Abstract Drinking water quality and its public health effect are ignored in urban slum households of Ethiopia. The aim this study was to assess physicochemical microbial drinking stored Hawassa City, Cross-sectional conducted a total 120 samples were collected from 60 (60 tap, households) test the quality. Wagtech Potalab + PTW − 1000 used parameters. Physicochemical parameters—temperature, tur...

Drinking water quality assessment in Kathmandu valley has always been crucial with reference to public health importance. The objective of this study was assess the drinking respect physiochemical and microbiological parameters. A total 63 random samples were collected from different sources like stone spout, tap, well, boring, hand pumps jar wards Kageshwori Manohara Municipality, Kathmandu. c...
