Craig Adams - Dev Nation Water Treatment

Testing and Development of Water and Sanitation Technologies for Developing Nations

The Adams Research Group is focused on both the testing of current technologies and analytical methods employed in developing nations, as well as the development of new technologies and treatment approaches.

Filtration Technology Testing

Many different filtration technologies are employed in rural and peri-urban environments in developing nations. Some of these technologies remain effective for long periods of time (with proper maintenance) while other have been shown to actually degrade water quality after relative short periods of time. Further, different filters are designed to address varied treatment objectives with respect to biological, chemical and physical water quality parameters. The Adams Research Group is conducting rigorous testing and validation of commonly used filtration technologies with the aim to develop guidance for their implementation and maintenance.

Appropriate Treatment Technology and Water Quality Method Validation

The Adams Research Group is focused on testing both commonly used water treatment technologies and water quality analytical methods employed in developing nations with the objective to develop guidance recommendations.

Ceramic Filtration for Arsenic Removal

The Adams Research Group has been investigation means to removal arsenic and other heavy metals in modified ceramic filters of various configurations. Reference: Robbins, E., Guo, J., Adams, C. (2014) “Removal of As(III) and As(V) in Surface Modified Ceramic Filters,” J. Water, Sanitation, and Hygiene for Development (IWA), 4(2), 214-222.

Thermal Disinfection of Human Compost

Composting latrines are a common and valuable technology especially in areas of shallow groundwater and/or where nutrient recovery is important. Disinfection of parasites is important for this technology if there is the possibility of the compost serving as a vector for pathogen transmission. We are publishing research results on the use of thermal disinfection approaches including the ability to inactivate Ascaris eggs.
