Literature Review of Feedback Control for Drinking Water Purification
The disinfection of raw water plays an important role in environmental engineering. In this document we overview several feedback controllers proposed by different authors to purify the water contained in water distribution systems. Several techniques to purify the water and the sensors needed as part of the whole system are presented to provide an overview of the components and processes encou...
متن کاملApplication of Magnetic Nanoparticles in Drinking Water Purification
Pathogenic bacteria are fetal to human health, requiring cost-effective and safe approaches to be removed from drinking water source. With poly-allylamine-hydrochloride (PAAH) stabilization, magnetic nanoparticles (MNPs) were introduced in this study to remove pathogenic bacteria by electrostatic interaction and magnet capture. High removal efficiency was achieved for four main pathogenic speci...
متن کاملThe Effectiveness of Home Water Purification Systems on the Amount of Fluoride in Drinking Water
STATEMENT OF THE PROBLEM Water purification systems for domestic use have drawn significant attention over the past few years. This can be related to the improvement of public health and concern for water contamination. PURPOSE The aim of this study was to evaluate whether home water purification systems eliminate the essential materials such as fluoride besides filtrating the heavy ions and ...
متن کاملWater purification of arsenic- contaminated drinking water via air gap membrane distillation (AGMD)
Arsenic contamination in shallow tubewell water is a serious health issue in Bangladesh and other Southeast Asian countries. Rural and remote areas in these locations continue to face tremendous challenges in providing access to affordable and safe arsenic-free drinking water. In recent years, intensive efforts have been undertaken to identify appropriate technologies for arsenic removal. This ...
متن کاملFungal Contaminants in Drinking Water Regulation? A Tale of Ecology, Exposure, Purification and Clinical Relevance
Microbiological drinking water safety is traditionally monitored mainly by bacterial parameters that indicate faecal contamination. These parameters correlate with gastro-intestinal illness, despite the fact that viral agents, resulting from faecal contamination, are usually the cause. This leaves behind microbes that can cause illness other than gastro-intestinal and several emerging pathogens...
