IntroductionDesignOperation and MaintenanceOperation and Maintenance TrainingBibliographyThe limited amounts invested in the treatment of safe water in rural areas are partly explained by the high cost of water treatment systems. Consequently, the majority of rural communities are still drinking superficial water that does not meet the required standard of quality, causing serious health problems. In many cases, the high cost of water treatment systems and the poor quality of water deter investment in even the simplest systems of 在appropedia上查看更多信息

Slow Sand Filtration an overview ScienceDirect Topics

Seán Moran, in An Applied Guide to Water and Effluent Treatment Plant Design, 2018. Introduction. Nowadays fewer biological processes are used in modern clean water treatment (though ironically in the days of slow sand filtration, there was more biology than chemistry in clean water treatment).This is mainly because clean water usually has fewer of the nutrients that are needed to sustain life.
