Drinking water in the vast Arctic Canadian territory of Nunavut is sourced from surface water lakes or rivers and transferred to man-made or natural reservoirs. The raw water is at a minimum treated by chlorination and distributed to customers either by trucks delivering to a water storage tank inside buildings or through a piped distribution system. The objective of this study was to character...
The liquid wastes produced during the processing of radioactive materials at the Savannah River Site were initially stored in large underground tanks constructed of carbon steel. These liquid wastes were generated from the Purex process (for producing plutonium) and the HM process (for producing tritium). The liquid wastes were designated as high-level wastes and lowlevel wastes. As the product...
[1] In the face of global change, which is characterized by growing water demands and increasingly variable water supplies, the equitable sharing of water and the drought proofing of rural livelihoods will require an increasing physical capacity to store water. This is especially true for the semiarid and dry subhumid regions of sub-Saharan Africa and Asia. This paper addresses the following qu...
This paper reports an innovative method based on electrochemistry to adjust the pH in nutrient solutions used in hydroponics. The required quantity of H or OH ions is produced insitu through electrolytic water decomposition. Because the direction and rate of electrochemical reactions can be easily manipulated by controlling the polarity and voltage applied between electrodes, the most important...
In china, atmospheric storage tanks are not included in the management of special equipment, and therefore they are not required to be inspected compulsorily. There is larger difference between China and developed countries on atmospheric storage tank inspection technique than the other techniques on the inspection of pressure vessels. It is widely believed that the strength worsening and perfo...
The importance of controlled water supply is indispensable for the sustainability in low land paddy production, which varies enormously from region to region and country to country. What essential is the degree of importance given to the three elements of water management namely (i) resource management within the watershed (ii) conveyance to the crop fields and (iii) management within farm fiel...
Domestic rainwater tanks have become commonplace in Australia's urban landscape, and have become the physical embodiment of the changing relations between householders, water, and water authorities. The aim of our research was to understand these changing relations by examining how domestic rainwater tanks are inscribed with meanings and assumptions and thus mediate a relationship between house...
