"In the aftermath of a disaster, individuals and communities often lose access to adequate quantities of clean water required for proper hygiene and consumption. This can result in an increased incidence of diarrheal diseases, one of the major contributors to the overall death rate following a disaster. To limit the prevalence of such diseases, the swift re-establishment of a clean water supply is vital. In emergency situations, water treatment is usually achieved through a chemically-assisted “batch” sedimentation strategy inspired by conventional treatment approaches. In this process, aluminum sulfate is used to condition suspended particles for quicker settling and clarification. For efficient settling to occur, conditioned particles must be provided optimum conditions to collide and agglomerate. This process is referred to as flocculation, and is achieved by inducing specific energy inputs to the system. The flocculation process however is not included in “batch” treatment for the sake of simplicity in resource-limited contexts, and thus, longer settling times can result. With the onset of monsoon season, the “batch” water treatment system currently implemented in Rohingyan Refugee camps in Bangladesh will experience decreased drinking water production due to high source water particle loadings. The proposed solution requested by Oxfam, a major humanitarian relief agency, is to design and implement a portable flocculation unit to the existing system to improve particle settling times. The research conducted aims to determine whether successful flocculation can occur in a portable flocculator designed within the size and cost requirements of the project."
