Welcome to manzwaterinfo.ca,
the official site for the BioSand Water Filter
(BSF) and for
cooperative discourse on water management.
The BSF and its
applications are at the center of a rapidly evolving field
that provides cheap, simple water purification systems to
those who need it most.
Here you'll find
information for BSF users, investors, students, professionals
- anyone interested in
inexpensive, effective, simple water purification.
MISSION STATEMENT below.
Introduction to the BioSand Water Filter
Individual BSFs with capacities ranging from 20 to 960,000 litres per hour are available. Systems of BSFs can be expected to treat up 20,000,000 litres per hour.
In 1990 the first ideas for the development of the BSF
were born. Since then, numerous individuals and supporting
organizations have been trained in the use and application of
models specifically designed for humanitarian projects around
the world. These individuals passed on their training to
others, and over the past decade hundreds of BSF projects have
been established. The technology was patented and commercial
versions were designed, manufactured and marketed.
Most BSF's are used by individual families, often shared with
extended family members, friends and neighbours. The safe
water produced is used for drinking, food preparation,
personal hygiene and sanitation. Most of these BSF's have a
capacity to produce between twenty and sixty litres of water
Several community-scale BSF systems are currently operating in
North and Central America. Unfortunately, community scale
systems delivered to Africa were never installed due to
political unrest. The smallest systems provide water for
several families while the largest provide water for tens of
thousands of people.
BSF's are used alone or in combination with pre- and
post-treatment to remove water borne pathogens (helminths,
parasites, bacteria and viruses), particulate matter, colour
and other DOC, BCOD, organic toxins and inorganic toxins such
as arsenic and mercury. BSF systems capable of removing
fluoride are currently being developed.
BACK TO TOP
It's now estimated that there are more than 200,000 BSFs in more than 70 countries in Africa, Europe, Asia, North,
Central and South America, the Caribbean and the South Pacific - with several hundred more being constructed and installed every week.
This website focuses on the smaller scale humanitarian
models, which differ from the larger capacity versions only in
the complexity of their mechanical systems. The intention is
to report and discuss all relevant elements of the BSF
- Project implementation
Information, web links and references that support the
successful use of the BSF technology for the provision of safe
water will also be reported and discussed.
The objective is to provide as much useful guidance as
possible to all of the organizations and individuals involved
with or interested in implementing BSF projects, using the BSF
technology, evaluating BSF technology and its implementation,
research and development of the BSF technology (at least as it
pertains to humanitarian applications), funding BSF
activities, regulatory bodies concerned with certifying BSF
technology and any other activity pertaining to the successful
use of the BSF technology worldwide.
The BSF technology and its applications are rapidly
evolving, and there is a constant stream of information to
communicate and share. The internet provides unparalleled
Please feel free to email me. Your ideas, advice and
experiences are important and welcome, and to the extent
possible will be shared with the world.
Thank you for your interest and support.
