The need for clean water has risen exponentially over the globe. Millions of people are affected daily by a lack of clean water, especially women and children, as much of their day is dedicated to collecting water. The global water crisis not only has severe medical implications, but social, political, and economic consequences as well. The Institute of Catholic Bioethics at Saint Joseph's Univ...

Abstract Pathogenic protozoa endanger human health and challenge water treatment, especially during outbreaks in developing countries. For instance, Giardia spp. cysts can recirculate the filter backwash (FBW), reinforcing relevance of their detection protocol negligible matrices. This study aimed to detect FBW by direct centrifugation (DC) immunomagnetic separation (IMS) with addition detergen...

In this paper, results of new intermittent sand filter design was presented. Drawer Compacted Sand Filter DCSF is a modified design for sand filter, in which sand layer is broken down into several layers (10 cm each) and placed in a movable drawers separated by 5 cm space each. Lab-scale DCSF was designed and operated in Surrey University's lab for 49 days and fed by synthetic greywater. 30 cm ...

This paper describes an analysis of the effects adjusting intensity filter backwash to water temperature. The consequences lack such adjustment for life beds, amount used backwashing, energy backwashing and quality first filtrate are presented. In order determine losses profits resulting from controlling depending on its temperature, was carried out at a treatment plant in southern Poland. Labo...

The intermittent slow sand filter (biosand filter) is a household-scale drinking water treatment system known for its simplicity and ease of use. This research examines several factors affecting the flowrate of the biosand filter as well as schmutzdecke disturbance, volume of water treated, and previous microbial loading to determine their effect on removal of microbes. It is recommended that a...
