Abstract<\/strong><\/h3>\n

Ceramic water filters are promising household water treatment technology, as they are capable of removing waterborne pathogens and thereby reducing diarrheal disease. Flow rates are the main quality control criterion for manufacturing, and multiple theoretical flow rate models have been published. <\/span><\/p>\n

This dissertation presents the results of combined experimental and theoretical studies of flow rate variation in ceramic water filters in\u00a0<\/span>frustumand<\/span> disk-shaped ceramic water filters. <\/span>Also investigated is how clay mixtures\/plasticity affects the strength of the ceramic water filters. <\/span><\/p>\n

Furthermore, residual strengths of filter specimens that had undergone cold-shocking at temperatures 750, 850 and 950 are presented and trends explained via bridging models. Firstly, in this dissertation six frustum-shaped ceramic water filters of the same\u00a0<\/span>clay: sawdust<\/span>\u00a0composition was tested.<\/span><\/p>\n

Each ceramic water filter was filled with water and allowed to filter 20 times. Each time, the flow rate and water level are measured for consecutive 12 hours. <\/span>Permeability values are estimated for each run of the ceramic water filters.<\/span><\/p>\n

Statistical analysis was performed on flow rates (in the first hour), mean flow rates and estimated permeability values. <\/span>The flow rate values (in the first hour) for the six ceramic water filters were found to be between 1.4 \u2013 3.0 L\/hr. <\/span><\/p>\n

An effective permeability was obtained for ceramic water filters with a range of micro- and nano-scale pore sizes. The statistical variations in the flow rates and effective permeabilities were elucidated along with the potency of a multiple ceramic water filter system for scale-up studies in serving communities that need portable water.<\/span>\u00a0<\/span><\/p>\n

Introduction<\/strong><\/h3>\n

1.1 Background of the Study<\/strong><\/p>\n

It is estimated that 1.8 million deaths per year and 61.9 million disability adjusted life-years are attributed to the drinking of unsafe water and poor sanitation. The World Health Organization (WHO) also suggests that over 99.8% of the deaths are caused by unsafe water, sanitation and hygiene in developing countries. <\/span><\/p>\n

Furthermore, in developing countries most of the childhood mortality occurs in children that are less than five years old. <\/span>Many of those who have access to such improved drinking water sources have contamination issues and usually require further treatment at the point of use. <\/span><\/p>\n

This information is confirmed in recent global joint monitoring 2014 report of WHO\/UNICEF on progress made on sanitation and drinking water. The global Millennium Development Goals (MDG) target for number of people to improved water sources has been achieved.<\/span><\/p>\n

The target for sanitation, however, was not attained and this may be a predominant force in contaminating the improved water sources. Governments, non-governmental organizations, and researchers have been instrumental in achieving the MDG for improved water sources. <\/span><\/p>\n

It is undisputable fact that inculcating household water treatment systems (HWTS); such as ceramic water filters (CWF) which has high performance were paramount.\u00a0<\/span><\/p>\n

The important criteria often used in selecting high performance HWTS include: ability to remove pathogens, removal chemical contaminants (such as fluoride and arsenic), flow rate, etc. <\/span><\/p>\n

Other factors to be considered are maintenance cost; purchasing cost; user-friendliness with little or no training; reasonable amount of water to be discharged within reasonable amount of time (flow rate); socially accepted and culturally accepted in the user environment.<\/span>\u00a0<\/span><\/p>\n
