    sand filter
  • The oldest and most basic filtration process, which generally uses two grades of sand (coarse and fine) for turbidity removal or as a first stage roughing filter or pre-filter in more complex processing systems.

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

  • (sand filters) Devices that remove some suspended solids from sewage. Air and bacteria decompose additional wastes filtering through the sand so that cleaner water drains from the bed.

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





    pressure
  • The force exerted per unit area

  • the force applied to a unit area of surface; measured in pascals (SI unit) or in dynes (cgs unit); "the compressed gas exerts an increased pressure"

  • coerce: to cause to do through pressure or necessity, by physical, moral or intellectual means :"She forced him to take a job in the city"; "He squeezed her for information"

  • The continuous physical force exerted on or against an object by something in contact with it

  • The use of persuasion, influence, or intimidation to make someone do something

  • a force that compels; "the public brought pressure to bear on the government"

easy to make. start with the right size press-on lens cap (BH has them) and cut a circle in the middle with a compass or calipers.

cut the hole out with an x-acto knife and sand or file smooth. the plastic will flex enough to let the filter 'mount' - just by pressure. no glue needed (yet).

Lake McKenzie





Freshwater lake, that is pretty much in the middle of the island. It's got fresh water in it, because of the filtered salt water from the ocean, that got filtered by the pressure of the ocean on the sand island.
