Field-testing solutions for drinking water quality monitoring in low- and middle-income regions and case studies from Latin American, African and Asian countries

Assessment of Nitrates and Nitrites in Borehole Water from the Southern and the Northern Region of Côte d’Ivoire (West Africa)

“…According to the United Nations, nearly 884 million people worldwide do not have access to quality drinking water, and among them, two million people mostly young children die each year due to diseases caused by unsafe water consumption (UN, 2022) [3] [4]. In Africa, over 400 million people, almost half of the population, lack proper access to a safe and sufficient water resource [5] [6]. In Côte d'Ivoire, nearly half of the total population lacks access to clean water.…”

Experimental approach and analysis of the effectiveness of a tubular helical flow flocculator for water supply in developing communities

“…Conventional water treatment plants are essential to provide an efficient service of quality liquid to the population; However, the costs, knowledge and adaptation of spaces necessary for their operation have been the aggravating factors so that in developing communities there is no possibility of implementing them [ 5 , 6 ]. Therefore, the use of new treatment techniques is required to generate accessible, quality drinking water that integrates optimal processes from its intake to its distribution in homes [ 7 , 8 ]. Within the treatment process of a conventional purification plant (CPP) there are two essential processes and the subsequent processes depend on their efficiency, these are coagulation and flocculation, in the first it is necessary to incorporate a chemical coagulant and in the second a flocculant or coagulation aid [ 9 , 10 ].…”
