Abstract:
Due to water resources shortage in Saudi Arabia, the water authority relies on intermittent water supply system. In this system, the city is divided into a number of small sectors, and water is pumped rotationally between the sectors according to an operational schedule. The frequency of water pumping to a given sector varies from several days to weeks. Between the intermittent water supply, pipes remain empty and dry for long periods. Consumers construct the underground storage water tanks to meet their demands. Lack of sewerage systems in many areas with high water table in the city lead to

Abstract:
The current research was undertaken in the north of Benin Republic, to assess the pollution level of drinking water; with an emphasis on water sources (boreholes, wells, surface water, and fountain post) and water storage by households. To this end, five villages of the town of Manta were the target. The methodologywas based on chemical and bacteriological analyses of water samples collected in October 2015, from ten water sources and four households. The results of chemical analyzes, revealed that two out of five (5) boreholes sampled, had higher than normal nitrate concentrations. Two (2) we

Abstract:
This study was intended to evaluate the quality of some bottled waters available in Iraqi market, by testing their physical, chemical and biological characteristics. These samples produced by four companies during the period of December- 2016 to April-2017. The selected companies had the biggest sells and were under the trade names of AlluLua, Ala, Alwafi, and Venesia. The results showed that most bottled waters samples characteristics were in compliance with Iraqi and international standards, with some superiority in water quality for the trade mark Allulua upon the other companies, but the t

SummaryThe development of devices to sample milk at the clawpiece and at the end of the pipeline during milking are described. The results of tests to compare the bacteriological and compositional quality of milk collected from the sampling devices or from the recorder jar or milk cans were similar, demonstrating that the samples provided accurate and representative values. The use of the in-line sampling technique, whereby samples of the milk are taken at three points during its passage through the milking plant, to assess accurately the sources of bacterial contamination of bulk tank milk on

Abstract:
Ozone is widely used in water disinfection and the concentration needed for the effective microbial elimination depends on the water source. In many bottled water producing industries, products containing ozone are quarantined after application to allow decomposition into diatomic oxygen molecules and oxygen atoms in order to eliminate any toxic effect. A process optimization was carried out to determine the ozone decomposition time in a table water producing factory in southern Nigeria. To this end, bottled water products injected with the ozone were collected from a bottling line immediately

A total of fourty (40) snacks were screened using standard pour plate method while gram staining and biochemical test were carried out for the identification of various isolates. The samples had varying degree of bacterial contamination ranging from 2.0 x 102 - 1.4 x 103 cfu/g. The bacteria isolates found included Bacillus subtilis 29 (34.12

Abstract:
Abstract Rainwater harvesting (RWH) provides household water supply to rural and peri-urban populations that do not have access to centralised water services. The climate in south-west Uganda is particularly well suited to RWH due to bi-annual rainy seasons, which allows for the collection of rainwater to occur over two periods throughout the year. Water quality from RWH, however, depends on how well risk of contamination (ROC), from catchment to consumption, is managed. Using a mixed-methods approach, we assessed the maintenance practices and water quality of 20 RWH installations in Uganda in

Twenty-three Prim'Holstein lactating cows were inoculated. To be challenged, the mammary glands had to be productive, free of pathogenic bacteria, and with somatic cell counts (SCC) of <200 000 cells/ml.

Abstract:
The results of a 20-month period study in Brazil were analyzed to compare horizontal-flow constructed wetlands (CW) and waste stabilization pond (WSP) systems in terms of land area requirements and performance to produce effluent qualities for surface water discharge, and for wastewater use in agriculture and/or aquaculture. Nitrogen, E. coli and helminth eggs were more effectively removed in WSP than in CW. It is indicated that CW and WSP require similar land areas to achieve a bacteriological effluent quality suitable for unrestricted irrigation (103E. coli per 100 mL), but CW would require
