Final Product
Step one: Grind one eighth of a cup of dried okra seeds into a powder. This may be done in various ways depending on what the user has access to such as with a simple grain mill, pounding with a rock or hammer, or rolling the seeds between to rocks to break them down.
Step two: Add one eighth of a cup of salt (added to draw the polymers out) and the one eighth of a cup of the okra “flour” to one liter of water. Mix for ten minutes and then allow to rest until seed hulls settle on the bottom. This volume of solution should be able to produce about seventy liters of clean water.
Step three: Add fourteen mL of the solution per liter of dirty water to clean.
Step four: Using some form of mixer depending on what the user has accessibility to, stir dirty water for eight minutes at approximately one hundred rotations per minute. This allows the polymer to become evenly distributed throughout the water.
Step five:Then reduce stirring speed to fifty rotations per minute for eight minutes. This allows tiny flocks to form.
Step six: Then reduce speed to thirty rotations per minute to allow slightly bigger flocks to form.
Step seven: Next, stir for another eight minutes at fifteen rotations per minute to allow big flocks to form without breaking them up. It is crucial that only slow stirring occurs at this state because of the risk of breaking up the flocks.
Step eight: Allow water to set for at least thirty minutes in order for the particulate to settle.
Step nine: Pour the top portion of the water out through a filter into another container. Efficient filters can be made in various ways depending on what is available to the user. Cloth, sand, and charcoal can all be used for efficient filtration. After water is efficiently filtered, our tests show that it should be acceptable for consumption. If further disinfection is desired, user may do so by boiling water or addition of bleach to the water.
