Filtration through a sand and pebble filter removes most of the impurities remaining in water after coagu-lation and sedimentation have taken place. After a large amount of sediment have settled on the bottom of the bottle of swamp water, carefully - without disturbing the sediment - pour the top two-thirds of the swamp water through the filter.
3-4 Coffee Filters. Dirty Water. A Plastic Cup with a Hole Cut in the Bottom. Begin by getting a jar full of dirty water. We went to a little pond nearby to collect some water. In the plastic cup, start by lining the bottom with the coffee filters. Then place a layer of clean sand followed by a layer of gravel. Place the cup into an empty jar.
4. In one water bottle add sand first and then gravel, in the other bottle put the gravel in first and then the sand. The idea is to see if the order of filtering materials makes a difference to how well the water is filtered… all about variable testing!
Homemade Simple Water Filter. You can easily make a water filter with children using recycled materials found at home. This project is best for children in grades three through six, but it will work for all ages. Construction of the homemade water filter will take about an hour to build.
Commercial Water Filters are ideal Filtration Systems for removing many water contaminants on large scale in places such as large private residences (over 4000 sq. feet), businesses, manufacturing facilities, apartment buildings, retail establishments, restaurants and schools.
This Water Filtration Lesson Plan is suitable for 5th Grade. In this water pollution and filtration lesson plan, 5th graders read the story 'Saving Salila's Turtle' and discuss the impact pollution has had on the Ganges river. Students work in groups to brainstorm different types of water pollution and then work together to make three different filtration systems.
2. Build your filter cartridge. Until a few years ago, water needed to sent up to the space station in large containers the size of duffel bags. But in 2010, a filtration system was installed that made it so that water could be cleaned and reused onboard the space station. To build your own filtration system, you'll need a filter cartridge.

The pharmaceutical grade post filter seals the carbon block to make sure it stays intact and in its place between filter and the housing. This protects the carbon and extends the life of your carbon water filter, giving you fresh drinking water much longer than when using other water filters.
Water filtration is a physical process of separating suspended and colloidal particles from water by passing water through a granular material. The process of filtration involves straining, settling, and adsorption. As floc passes into the filter, the spaces between the filter grains become clogged, reducing this opening and increasing removal.
Have students draw schematics of the layers. Once completed, give each team 25 ml of the dirty water to begin to filter in their test tubes. Once filtering is complete, have them bring the test tubes to you for observation. Decide if the water is A, B or C grade and help them measure their sample in a graduated cylinder.
Commercial Grade Water Filtration Systems When it comes to commercial water filtration systems, you need a water filter system that will not only give you and your customers access to the healthiest water available but one that's easy to install, and requires minimal maintenance/repairs.
To find out how water filters work, it is probably best to have a look inside the filter. Most of the filters that are used for home water treatment are carbon filters. That means the material inside the filter is carbon or a special form of it, called activated carbon or activated charcoal, which is shown in Figure 1.
There are sediment filters rated at 5.0 microns to filter out larger particulates above that size. Other RV water filters may be rated at 1.0 or even 0.5 microns for even finer filtration to make the water even cleaner. Some of the cheaper water filters such as the Camco 40045 TastePURE Inline RV Water Filter have a 20-micron sediment filter.

Filtration Examples. The most common example is making tea. While preparing tea, a filter or a sieve is used to separate tea leaves from the water. Through the sieve pores, only water will pass. The liquid which has obtained after filtration is called the filtrate; in this case, water is the filtrate.
