TL;DR: In this article, the authors studied the survival and transport of a model enterovirus (BE-1) and faecal coliform bacteria in four on-site wastewater treatment systems (three conventional and one low pressure, small pipe diameter, pumped system) located in sandy soils typical of the coastal plains.
TL;DR: In this paper, the effect of leachate from the major landfill in northern Jordan, El-Akader on the ground-water was investigated, including pH, total hardness, electrical conductivity, and total dissolved solids for the physical parameters.
TL;DR: This study investigates helminth eggs removal and inactivation efficiency in a treatment process combining faecal sludge dewatering and subsequent co-composting with organic solid waste as a function of windrow turning frequency, complying with the WHO guidelines 2006 for the safe reuse of FS.
