My kids had a blast making this sand filter because it combined their two favorite things: water and dirt.

Filtered water then flows through the filter bed in the opposite direction. The polluted matter is released and flows away along with the rinse water. The filtration process can then resume.

Sediment Filtration is an effective method for reducing turbidity in water caused by the presence of suspended solids such as silt, sand or clay. Sediment Filters remove suspended matter such as sand, dirt, rust, loose scale, clay or organic material from the water. Untreated water passes through a filter medium which traps suspended matter.

Chemical Treatment and Filtration. Filter Design: Greensand filters are typically designed to flow at 35 gpm per square foot of filter surface area and need a minimum of 12 gpm per square foot for backwash. Backwash should be initiated manually or by pressure differential switch when the differential pressure across the filter increases by 12 psi.

Quartz sand, silica sand, anthracite coal, garnet, magnetite, and other materials may be used as filtration media. Silica sand and anthracite are the most commonly used types. When silica is not suitable (, in filters following a hot process softener where the treated water is intended for boiler feed), anthracite is usually used.
