Equipment/skill required
Porous barrier: cost and efficiency depends on the barrier: clean woven fibers (cotton cloth, linen, others) Moringa tree seed press cake, ceramic filter 
Water vessel 
Process
Fix the barrier on top of the water vessel. 
If using cloth it should be folded 4-8 times to create a thicker barrier. 
Pour water through the barrier into the vessel, trapping solids and particles on top of the barrier. 
Take care to only allow filtered water to reach the bucket.
