This book was released on 2021-02-25 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many developing countries, water demand is increasing while surface- and groundwater resources are threatened by pollution and overexploitation. Hence, a more sustainable approach to water resources management and water treatment is required. In this capacity, bank filtration is a natural treatment process that makes use of the storage and contaminant attenuation capacity of natural soil/rock. However, BF is site-specific and a significant knowledge gap exists regarding the design and management of bank filtration systems, particularly in developing countries. This research aimed to address these gaps and contribute to the transfer of bank filtration to developing countries. This study comprised both column and batch laboratory-scale experiments to determine the effect of environmental variables such as temperature, raw water organic composition and redox conditions on the removal of chemical pollutants such as organic matter, micro-pollutants and heavy metals as well as the mobility of iron, manganese and arsenic under anaerobic conditions. Ultimately, the effectiveness of BF for supplying high drinking water quality was assessed in a case study in Egypt. The study showed that more than 80% of biodegradable organic matter was removed during infiltration at temperatures between 20 and 30 °C. However, humic compounds enriched during BF, required post-treatment. Moreover, high humic content of infiltrating water reduced the removal of heavy metal and promoted the release of metal (loids) into the infiltrating water, rendering it more feasible to install BF wells within surface water systems with low levels of organic matter. Moderately-hydrophobic organic micropollutants were most persistent and required infiltration times longer than 30 days for complete elimination even at high temperatures (>20 °C). Finally, design parameters such as the number of infiltration wells should be configured to minimise the proportion of polluted groundwater in the pumped water. Overall, this study provides insight into the effectiveness of BF in removing chemical pollutants from surface water and proposes guidelines for the successful application of BF in developing countries where arid conditions and high temperatures prevail.

Book excerpt: A large segment of the population in undeveloped and developing countries drink untreated or partially treated water. Annually, 6 to 60 billion cases of gastrointestinal illnesses are continuously reported due to safe drinking water, and over 1.6 million people die due to these water-borne diseases. Owing to increasing concern about global water-related diseases associated with drinking water, finding an affordable and suitable way of water treatment is of great importance. Filtration is a promising point-of-use water treatment. Currently, most water filtration membranes are made of synthetic polymers derived from non-renewable resources. Negative factors like climate change, many different environmental pollutants and the reduction of oil resources give rise to increase the demand of biodegradable products over non-renewable resources. This book introduces a novel, cost effective and biodegradable filter; a so-called cellulose foam filter. The cellulose foam filter is a novel porous cellulosic derivative made via a foam-laid process and modified in order to act as a water filter. Improvements of wet strength performance and the biocidal activity of filters are two main tasks presented in this book. Wet strength improvement is achieved through a furnish formulation, and the addition of agents and antimicrobial activity are preformed using polymeric antimicrobial agents, guanidine-based polymers and �-poly lysine.
