The water situation in rural Cambodia deeply affects the poverty that is so prevalent in the communities we serve. To address this situation we needed a highly effective, low cost solution that could provide clean water consistently for years. The scale and scope of the water situation in Cambodia is what lead us to implement us to the BioSand technology.<\/p>\n
We chose BioSand filters because:<\/p>\n

BioSand technology is open source and royalty free, allowing us to build as many as our budget will allow. The materials to construct the BioSand filter are all available locally and are very affordable.<\/p>\n
A home filter unit can be constructed for $60 and will provide enough clean water for a family to drink, wash, and bathe with.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″ el_class=”Wash” css=”.vc_custom_1653893532395{padding-top: 12% !important;}”][vc_single_image image=”3944″ img_size=”full” alignment=”right”][\/vc_column][\/vc_row][vc_row css_animation=”fadeInUp” css=”.vc_custom_1653893178192{padding-bottom: 66px !important;}” el_class=”Unit”][vc_column width=”1\/2″ el_class=”Wash”][vc_single_image image=”3945″ img_size=”full”][\/vc_column][vc_column width=”1\/2″ el_class=”ABC” css=”.vc_custom_1653893815785{padding-top: 11% !important;}”][vc_custom_heading text=”Clean water pipes” font_container=”tag:h1|font_size:30|text_align:left|color:%23a8cc52″ use_theme_fonts=”yes” css=”.vc_custom_1649664834265{margin-top: 0px !important;margin-bottom: 0px !important;padding-bottom: 12px !important;}”][vc_column_text]The main components of the home filter box are concrete mix, sand and PVC pipe. We purchase all of these in the communities where the filters are constructed and used. This fuels the local economy and reduces transportation costs for the materials.<\/p>\n
The sand and gravel that make up the filter medium are mined from two mountain quarries in Kampong Speu province outside of Phnom Penh. Sourcing our filter medium in country is better for the environment and provides jobs for the local economy.[\/vc_column_text][\/vc_column][\/vc_row][vc_row css_animation=”fadeInUp” css=”.vc_custom_1653893167664{padding-bottom: 66px !important;}” el_class=”home-sale”][vc_column width=”1\/2″ el_class=”home-sale-HD” css=”.vc_custom_1653893839429{padding-top: 8% !important;}”][vc_custom_heading text=”Requires Community Investment” font_container=”tag:h1|font_size:30|text_align:left|color:%23a8cc52″ use_theme_fonts=”yes” css=”.vc_custom_1649664879584{margin-top: 0px !important;margin-bottom: 0px !important;padding-bottom: 13px !important;}”][vc_column_text]Each family that receives a BioSand filter actively invests in the process of bringing that filter to their family, and each community actively invests in bringing the filter to their school.<\/p>\n
Each family must invest $5 to receive a filter. They must provide the transportation to move the filter from the construction site to their home, participate in the construction and they must participate in the community education programs to ensure their filter is maintained and serves them well.<\/p>\n
Schools must provide a roof structure to cover the filter system and a water storage tank for the latrines.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″ el_class=”Wash”][vc_single_image image=”3946″ img_size=”full” alignment=”right” el_class=”home-Q”][\/vc_column][\/vc_row][vc_row css_animation=”fadeInUp” css=”.vc_custom_1653893157097{padding-bottom: 66px !important;}” el_class=”Unit Durable”][vc_column width=”1\/2″ el_class=”Wash” css=”.vc_custom_1653893083049{padding-top: 2% !important;}”][vc_single_image image=”3947″ img_size=”full”][\/vc_column][vc_column width=”1\/2″ el_class=”ABC regular” css=”.vc_custom_1653893856659{padding-top: 8% !important;}”][vc_custom_heading text=”Durable” font_container=”tag:h1|font_size:30|text_align:left|color:%23a8cc52″ use_theme_fonts=”yes” css=”.vc_custom_1649664896841{margin-top: 0px !important;margin-bottom: 0px !important;padding-bottom: 12px !important;}”][vc_column_text]The BioSand filter medium we use in our filters lasts for decades, requiring only regular maintenance.<\/p>\n
To clean the filter the family will stir the surface of the BioSand medium to release the trapped particles into the standing water. This water containing the particles is then removed from the filter. Then the surface of the BioSand layer is leveled and the filter is ready use again.<\/p>\n
Our home filter bodies are made of concrete and will last indefinitely. The first filters we constructed are still in operation today. Our school filters tanks are made from recycled materials and have a natural life of 15 years or more.[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” css_animation=”fadeInUp” css=”.vc_custom_1638413859738{padding-top: 66px !important;padding-bottom: 66px !important;background-image: url(https:\/\/www.clearcambodia.org\/wp-content\/uploads\/2021\/11\/background-color-1.png?id=1257) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}” el_class=”sand”][vc_column width=”1\/2″ css=”.vc_custom_1638109500713{padding-top: 33px !important;}” el_class=”Technology”][vc_custom_heading text=”BioSand Filter Technology Effectively Removes Pathogens and Contaminants.” font_container=”tag:h1|font_size:30|text_align:left|color:%23a8cc52″ use_theme_fonts=”yes” css=”.vc_custom_1649664921417{margin-top: 0px !important;margin-bottom: 0px !important;padding-bottom: 12px !important;}”][vc_column_text css=”.vc_custom_1636777293456{padding-right: 3% !important;}”]Slow sand filters have been shown to remove almost all the disease-causing organisms found in water. The BioSand filter has proven as effective as traditional slow sand filters, in both laboratory and field tests. The filter has been tested by various government, research, and health institutions, as well as by non-governmental organizations.<\/p>\n
Overall, these studies have shown that the BioSand filter removes:[\/vc_column_text][\/vc_column][vc_column width=”1\/2″ el_class=”sand-ab”][vc_single_image image=”3949″ img_size=”full”][\/vc_column][\/vc_row][vc_row css_animation=”fadeInUp” css=”.vc_custom_1641898363215{padding-top: 66px !important;padding-bottom: 66px !important;}” el_class=”How”][vc_column width=”1\/2″ el_class=”Wash”][vc_single_image image=”4046″ img_size=”full”][\/vc_column][vc_column width=”1\/2″ css=”.vc_custom_1638413199947{padding-top: 34px !important;}” el_class=”Works”][vc_custom_heading text=”How BioSand Technology Works” font_container=”tag:h1|font_size:30|text_align:left|color:%23a8cc52″ use_theme_fonts=”yes” css=”.vc_custom_1649664939352{margin-top: 0px !important;margin-bottom: 0px !important;padding-bottom: 12px !important;}”][vc_column_text css=”.vc_custom_1636780172170{padding-right: 3% !important;}”]The BioSand filter is made of a concrete shell on the outside with layers of sand used for water purification on the inside. The filter works through a combination of mechanical and biological processes. Water is filtered by sand particles and a biological layer that develops on the surface of the water, this layer is known as the biofilm.<\/p>\n
When water passes through the filter, the organic material it carries is trapped at the sand\u2019s surface and forms the biological layer. Over several weeks during the filter\u2019s initial use, micro-organisms colonize this layer and the water passing through the filter provides them with oxygen and food. These micro-organisms then remove contaminants in the water through predation. The rest of the filter structure further purifies the water through trapping, adsorption and the natural death of biological contaminants. See the diagram below for an illustration of this.<\/p>\n
The BioSand filter can purify between 20 and 60 liters per hour and can last for decades with simple maintenance.[\/vc_column_text][\/vc_column][\/vc_row][vc_row css_animation=”fadeInUp” css=”.vc_custom_1651760800544{padding-bottom: 66px !important;}” el_class=”Brief”][vc_column][vc_custom_heading text=”A Brief Tour of Our BioSand Logistics Center” font_container=”tag:h1|font_size:30|text_align:center|color:%23a8cc52″ use_theme_fonts=”yes” css=”.vc_custom_1651653583991{margin-top: 0px !important;margin-bottom: 0px !important;padding-bottom: 15px !important;}”][vc_row_inner][vc_column_inner width=”1\/6″][\/vc_column_inner][vc_column_inner width=”2\/3″][vc_images_carousel images=”3444,3445,3446,3447,3448,3449,3450,3451,3452,3453,3454,3455,3456″ img_size=”full”][\/vc_column_inner][vc_column_inner width=”1\/6″][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row css_animation=”fadeInUp” css=”.vc_custom_1641911340547{padding-bottom: 66px !important;}” el_class=”our-img”][vc_column][vc_single_image image=”1063″ img_size=”full”][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” css_animation=”fadeInUp” el_class=”AB-our-img” css=”.vc_custom_1653982767892{background-image: url(https:\/\/www.clearcambodia.org\/wp-content\/uploads\/2022\/05\/20160406015652.png?id=3943) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][vc_column][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” css=”.vc_custom_1653895679852{padding-top: 254px !important;padding-bottom: 254px !important;background-image: url(https:\/\/www.clearcambodia.org\/wp-content\/uploads\/2022\/05\/Water-img.jpg?id=3934) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}” el_class=”btn-vdo”][vc_column][vc_custom_heading text=”Where Can We Take You Next?” font_container=”tag:h1|font_size:35px|text_align:center|color:%23ffffff” use_theme_fonts=”yes” css=”.vc_custom_1653984248702{margin-top: 0px !important;margin-bottom: 0px !important;padding-bottom: 15px !important;}”][vc_row_inner el_class=”Take” css=”.vc_custom_1654859014548{padding-left: 3% !important;}”][vc_column_inner width=”1\/2″][vc_btn title=”Why Change Lasts” align=”right” link=”url:%2Fwhy-change-lasts%2F”][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_btn title=”Who We Are” align=”left” link=”url:%2Fwho-we-are%2F”][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"
