Full Description

This powerpoint presentation begins by providing a brief overview of drinking water in low-income countries (LICs), decentralized water treatment technologies, and issues associated with this technology. The development of small-scale low pressure membranefiltration (LPMF) is briefly presented. Research objectives of a baseline study for sustainable water supply in low-income countries are presented and include:assess a representative type of LPMF system withrespect to its efficacy and productivity in producing safedrinking water;investigate the impact of membrane fouling on thesustainability of the LPMF system; and,based on the findings obtained in experimentalevaluations, identify key issues associated with thetechnological sustainability of similar systems to be appliedto low-income countries. Operation protocols for short-term and long-term experiments are provided, along with design perspectives for pretreatment, fouling prediction, and system cleaning. Presentation conclusions indicate the following:a commercially-available LPMF system was assessed inregard to its performance and sustainability for LICs;it was found that this system was capable of producingclear and microbial-free drinking water at outputssuitable for community use; and,in order to adapt to low-income countries, redesignof the system was recommended for four majoraspects includingpretreatment for fouling control, implementation of bench-scale assessment,simplification of system cleaning scheme, andintegration of other treatment for additional contaminantremoval. Includes tables, figures.
