“…Ex situ applications of Fe 0 filters for safe drinking water were mainly tested and applied in the context of arsenic (As) removal in South Asia, Southeast Asia, and Latin America [57][58][59][60][61][62][63][64][65]. Selected aspects of the corresponding literature have been reviewed [26,30,66] and actualized [27][28][29]50,67].…”

Metallic iron (Fe 0 )-based filtration systems have the potential to significantly contribute to the achievement of the United Nations (UN) Sustainable Development Goals (SDGs) of substantially improving the human condition by 2030 through the provision of clean water. Recent knowledge on Fe 0 -based safe drinking water filters is addressed herein. They are categorized into two types: Household and community filters. Design criteria are recalled and operational details are given. Scientists are invited to co-develop knowledge enabling the exploitation of the great potential of Fe 0 filters for sustainable safe drinking water provision (and sanitation).

“…These include but are not limited to low arsenic removal efficiency and interference generated by iron, high sludge volume, high costs for capital, operation, maintenance and failure to remove other contaminants such as phosphate and iron present in groundwater [13][14][15] . Additionally, beneficiaries have to pay for arsenic removal filters, but most of the arsenic-mitigation technologies are not designed according to the geographical needs of the intervention areas.…”

This study seeks to understand factors that guide the decision-making process to adopt and implement the available arsenic-mitigation technologies in rural areas in the middle-Ganga Plain in India. A total of 340 households comprising 2500 people were surveyed. Socio-economic and demographic factors, water and sanitation status, time spent and distance travelled to collect water, arsenic awareness, willingness to pay (WTP) for arsenic-free water, people's trust in others and in institutions, social capital in communities, and preferences for sustainable arsenic-mitigation options were investigated. Arsenic treatment units (filters) and piped water supply systems were the most preferred sustainable arsenic-mitigation options in the surveyed villages. Less preferred arsenic-mitigation options include deep tube wells, dug wells, and rainwater harvesting systems. Binary logistic regression models for each arsenic-mitigation option were produced. Arsenic awareness, WTP, trust in agencies, trust in institutions and social capital were found to be the most significant factors for decision-making for preferring one arsenic-mitigation technology over the others. We recommend a mixed model of two arsenicmitigation options for the studied individuals, which could be a sustainable arsenic-mitigation option for them, considering their socio-economic and demographic conditions. Existing institutions should be strengthened, agencies empowered, and communities enlightened about arsenic problems.

“…To protect the public's health, the maximum permissible limit has decreased from 50 to 10 mg L −1 [4]. This influences treatment processes and the selection of alternatives to attain the best solution, which depends on numerous factors, such as: the size of the treatment device, arsenic concentration and distribution of species, chemical composition and degree of mineralization of raw water, guidelines for the residual arsenic concentration, economic constraints and investment, operations and maintenance concerns, among others [5].…”

The present study was conducted in Naranjo County located in the municipality of Mixco, Guatemala. The water supply source comes from two wells with a maximum flow of 25.24 and 33.44 L·s . The aim of this study was to conduct laboratory tests, basic engineering and supervision of the construction and evaluation of an operations plant using two configurations, A (low-rate sedimentation and ceramic filter) and B (high-rate sedimentation and clinoptilolite filter), to remove arsenic present in water for human use and consumption. This plant supplies water to Naranjo County in Mixco, Guatemala (5000 inhabitants). First, a laboratory Jar Test was performed to evaluate arsenic removal efficiency. And second, a conventional clarification plant was then built (design flow: 25.24 L·s ) for arsenic, values that comply with Guatemalan standards. For this case, the relation between Fe(III) dosage/mg and As(V) removal was 1:46.
