MICROBIOLOGICAL AND PHYSICOCHEMICAL ANALYSES OF STORED GROUND WATER IN THE EKEHUAN CAMPUS, UNIVERSITY OF BENIN, BENIN CITY

The culturable microbial and physicochemical quality of stored ground water supplied to three hostels, the health center and Optometry clinic at the Ekehuan campus of the University of Benin was evaluated. Routine procedures such as pour plate, multiple tube dilution and usage of appropriate meters such as pH meter and conductivity meter were employed. The mean bacterial and fungal counts ranged from 1.03×105 cfu/ml±1.2 to3.27×105 cfu/ml± 3.1 and 0.9 ×105 cfu/ml ± 2.6 to1.97×105 cfu/ml ± 0.6 respectively. Eight microbial isolates; Klebsiella mobilis, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella sp., Aspergillus niger, Penicillium sp. and Rhizopus stolonifer were tentatively characterized. The mean pH values ranged from 7.36 ±0.4 to 8.67 ±0.1. It is recommended that the plastic storage tanks should be flushed and washed regularly. This measure would reduce or eradicate the biofilms associated with the interior surfaces of the plastic tanks

Barriers and Enablers to Intervention Uptake and Health Reporting in a Water Intervention Trial in Rural India: A Qualitative Explanatory Study.

Consumption of unsafe drinking water contributes to the global disease burden, necessitating identification and implementation of effective, acceptable, and sustainable water interventions in resource-limited settings. In a quantitative stepped-wedge cluster randomized trial of a community-based water intervention in rural India, we identified low rates of intervention uptake and reported diarrhea. To better understand and explain these findings, we performed a qualitative study examining barriers and enablers to intervention uptake and health reporting using the COM-B model, where capabilities, opportunities, and motivators interact to generate behavior. We conducted 20 focus groups and one semi-structured interview with participants and four focus groups with data collectors. Multifactorial barriers to intervention uptake included distorted perceptions of water-related health effects, implementation issues that reduced treated water availability; convenience of, and preference for, alternative drinking water sources; delivery of water to plastic storage tanks (perceived as affecting water quality and taste); and resistance to change. Enablers included knowledge of water-related health risks, proximity to tanks, and social opportunity. Barriers to health reporting included variability in interpretation of illness, suspicion regarding the consequences of reporting disease, weariness with repeated questions, and perceived inaction on health data already provided; low survey implementation fidelity was also important. Enablers included surveyor initiatives to encourage reporting and a sense of social responsibility. This qualitative explanatory study allowed better understanding of our quantitative results. It also identified obstacles and facilitators to implementing and evaluating community water interventions, providing insight on how to achieve better intervention uptake and health reporting in future studies.

Construction and Evaluation of Rainwater Harvesting System for Domestic Use in a Remote and Rural Area of Khulna, Bangladesh.

Scarcity of pure drinking water during the dry season (November–March) is a major problem in Bangladesh, which needs to be addressed. This crisis has been further aggravated due to surging populations. Rainwater can provide some of the cleanest naturally occurring water and can hold a great potential in dealing with the current challenge of acute arsenic poisoning as well as physical water scarcity in many parts of Bangladesh. In this connection, rainwater harvesting (RWH) system has been constructed in a very remote and rural village in Khulna, Bangladesh, for a 4-membered household. It consists of a concrete catchment of 40 m2 area, a supporting and collection system made of PVC pipes, and two locally available plastic storage tanks having capacity of 2000 L each. The study also investigates the quality aspects of the stored rainwater, which include measurement of pH, alkalinity, hardness, total dissolved solids (TDS), iron, chloride, nitrate, and turbidity, using standard methods. The results showed that not only the quality of harvested rainwater is good but also the amount of water is enough for a 4-membered household to meet its domestic use throughout the year.

Assessment of water quality of first-flush roof runoff and harvested rainwater

Summary Six pilot rainwater harvesting systems were installed in five urban, suburban and rural houses, and on a university campus. The systems consist of horizontal gutters to collect roof drainage, and downdrains which end into one or two plastic storage tanks. Devices were also provided to remove first-flush water. Water quality was monitored in the storage tanks and the first-flush devices during the 2-year period from October 2006 to November 2008. Water samples were collected at a frequency of once every 10 days, and analyzed according to potable water specifications to determine major anions (e.g., SO 4 2 - , NO 3 - , NO 2 - , F−, Cl−) and cations (e.g., NH 4 + , Na+, K+, Ca2+, Mg2+), total suspended solids, alkalinity, total phosphorus and microbiological indicators (e.g., total coliforms, Escherichia coli, Streptococcus, Clostridium perfrigens, Pseudomonas syringae and total viable counts at 22 °C and 37 °C). Furthermore, temperature, pH, dissolved oxygen and electrical conductivity were measured in situ. The mean concentrations of chemical parameters in harvested rainwater (with the exception of NH 4 + ) were below the limits set by the 98/93/EU directive for drinking water. Total coliforms were detected in 84.4–95.8% of the collected rainwater samples in the six tanks. E. coli, Streptococcus, C. perfrigens, P. syringae and total viable counts at 22 °C and 37 °C were found at low counts in samples of collected rainwater. The collected rainwater quality was found satisfactory regarding its physicochemical parameters, but not regarding its sanitary quality. Therefore, rainwater harvesting systems in this area could only supply water appropriate for use as gray water.

Demonstration of a zinc bromine battery in an electric vehicle

The zinc bromine battery is a high energy density battery that utilizes low cost materials. The battery is of unique construction utilizing plastic storage tanks for the zinc bromide electrolyte and plastic bipolar electrode stacks. This paper briefly describes the zinc bromine battery technology and the experience gained in installing and operating an electric vehicle with this advanced system. The described electric vehicle (The "T-Star") was tested in March 1993 on the Chrysler Proving Grounds in Phoenix, Arizona and it participated in the May 1993 American Tour de Sol capturing second place over all and first place in the student division.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Analysis and Design of Plastic Storage Tanks

The author has designed over one hundred major tanks that store plastic powders and pellets. This article gives some practical examples of how to analyze and design plastic storage tanks. Examples were taken from files of completed projects. All tanks are classified as either shallow or deep; an example of each is given. A series of four articles was written to report on a study about vessels made of aluminum or steel, and joined by bolting or welding. The first three articles are “Bolted Aluminum—Alloy Connections,” “Welded Tanks for Dry Bulk Plastic Storage,” and “Bolted Tanks for Storage of Plastics.” The state-of-the-art is presented. Although computer programs have been developed, some equations still used are empirical, and the assumptions are conservative. Not all authorities agree on the proper method of analysis. A research study of the whole tank, rather than its parts, should be made.
