    sand filters
  • A filter used in water purification and consisting of layers of sand arranged with coarseness of texture increasing downward

  • (Sand Filter) Uses sand to collect debris from water running through it.

  • (Sand filter) Sand filters are used for water purification. There are three main types; # rapid (gravity) sand filters # upflow sand filters # slow sand filters

  • (Sand Filter) A filtration system that removes contaminants by forcing the water through a vessel of sand.  These require backwashing about once a month and have no need for replacement chemicals.

Functionality and Social Acceptance of Safe Water Technology: Pond Sand Filter (PSF) and Rainwater Harvesting System (RWHs) in the South-West Coastal Region of Bangladesh



The coastal environment of Bangladesh is characterized by excessive salinity in both ground and surface water resulting in poor coverage because of the paucity of drinking water. Ground water cannot be used as drinking water due to excessive salinity, iron and arsenic problem. Moreover, most of the water supply options are not feasible in this region. So, people are suffering intensely due to lack of safe water sources and diarrheal diseases break out several times in each year causing death to hundreds of people. Pond sand filter and the rainwater harvesting system are widely used alternative safe water source among other modern technologies in the coast. This book, therefore, provides the scientific evidence to proof, which technology have more potentiality to solve long term water crisis in water scarce area. It will also help to evaluate the functional ability of pond sand filter and rainwater harvesting system and limitation of these technologies. Therefore findings of this study will be very significant for further expansion, planning, implementing of such technologies in not only in salinity affected coastal regions but also in other arsenic prone areas in Bangladesh.

This shot was taken looking away from the sunset at Yarramundi last week. I have been wanting to try some new post production techniques for a while but have not had the time. Finally last night I sat down and did my first one. I am happy with some aspects of it but I know there is much more to learn. This is just the first step

On Tuesday afternoon I went to Yarramundi after work for some sunset action. The colours were very nice and the reflections were strong. I could not shoot into the sunset because the river had flooded all of the good locations.
