Understanding Carbon Mesh Size: Smaller granules equal bigger performance
Full Abstract: Carbon filters for domestic water treatment are increasingly popular, but many water treatment professionals may not realize the impact carbon's 'mesh size' can have on a filter's performance. Mesh size, which indicates the range of particles sizes in a particular carbon product, is an important physical consideration. Other physical properties of activated carbon include its ...

Water, sanitation, and diarrhea incidence among children: evidence from Guatemala
Using household survey data for Guatemala, this paper investigates the role of water and sanitation infrastructure on diarrhea incidence in children. Hierarchical logit models of diarrhea incidence are estimated to account for potential regional heterogeneity of water and sanitation effects. Results indicate that the incidence probability of diarrhea is on average 20% lower in homes connected ...

Do sales models influence the purchase and use of ceramic filters in rural areas of Kenya and Bolivia?
Demand for safe water, as well as access to adequate and affordable products for drinking water treatment, is key for household water treatment (HWT) in low-income countries. Critical barriers, particularly in rural areas, are the lack of adequate marketing and sales models and the challenge of setting up distribution channels that reach low-income customers, leading to the unavailability of ...

The role of social networks on the uptake of household water filters by women in self-help groups in rural India
Household water treatment and safe storage (HWTS) has been shown to improve drinking water quality and prevent disease. Efforts to scale up HWTS among vulnerable populations have been limited, partly due to an incomplete understanding of the socio-cultural influences on decision-making around uptake of HWTS. In-depth interviews were conducted with women in self-help groups in rural India who were ...

Microbiological quality of chlorinated water after storage in ceramic pots
Household water treatment with sodium hypochlorite has been shown to reduce self-reported diarrheal disease in developing countries. Reported hypochlorite use, time since treatment, total chlorine residual (TCR), and E. coli concentration results from 589 household surveys in rural Kenya were analyzed to quantify the effect of exceeding recommended 24 hour post-treatment water storage time in ...

An optical method for characterizing carbon content in ceramic pot filters
Ceramic pot filter (CPF) technology is a relatively common means of household water treatment in developing areas, and performance characteristics of CPFs have been characterized using production CPFs, experimental CPFs fabricated in research laboratories, and ceramic disks intended to be CPF surrogates. There is evidence that CPF manufacturers do not always fire their products according to ...
