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 membrane
filtration (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 with
respect to its efficacy and productivity in producing safe
drinking water;
investigate the impact of membrane fouling on the
sustainability of the LPMF system; and,
based on the findings obtained in experimental
evaluations, identify key issues associated with the
technological sustainability of similar systems to be applied
to 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 in
regard to its performance and sustainability for LICs;
it was found that this system was capable of producing
clear and microbial-free drinking water at outputs
suitable for community use; and,
in order to adapt to low-income countries, redesign
of the system was recommended for four major
aspects including
pretreatment for fouling control, implementation of bench-scale assessment,
simplification of system cleaning scheme, and
integration of other treatment for additional contaminant
removal. Includes tables, figures.
