What Makes an Efficient Ceramic Water Filter?

What Makes an Efficient Ceramic Water Filter?

An important but brief study was published last year by individuals working with the RDIC factory in Cambodia to find what factors make a more efficient ceramic water filter. In this study several empirical tests were preformed to investigate the relationships between filter mix ratios and firing schedules. Perhaps the most relevant results demonstrated by these tests demonstrated the lack of corr...

Investigation of the Critical Parameters in the Production of Ceramic Water Filters

Isabelle Gensburger October 2011 The flow rate can be increased by: 1. increasing the porosity of the filter, by increasing the quantity of burn-out material in the clay mix; and 2. increasing the pore size, either by – changing the particle size distribution of the burnout material, or by – changing the maximum firing temperature. The bacteria removal effectiveness is only compromised when in...

Batch Consistency – Ceramic Pot Water Filters

At Potters Without Borders our focus is on the transfer of skills required to manufacture strong, effective ceramic pot water filters. Manufacturing filters as an appropriate technology requires the utilization of locally sourced skills and raw materials. For technicians, the main challenge is to go through the process required to develop a working filter body within a short time, using greatly va...
