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 anti microbial activity are performed using polymeric anti microbial agents, guanidine-based polymers and å-poly lysine.
