The mixture is then allowed to settle for 1-2 hours. The tap is then turned on so that the water can pass through a cloth screen and a sand filter in the lower bucket.

'''Coagulation-Flocculation: 2-Kolshi Filterfilter'''<br>

* Add ENPHO chemical (iron sulphate, sodium hypochlorite and ash) to a bucket of water

* Stir water for a few minutes

* Pass the water through a ceramic filter

'''Surface complexation: Sono Filterfilter'''<br>Each bucket has different media and functions:<br>* Top bucket: 3 kg iron filings and 2 kg coarse sand* Middle bucket: 2 kg fine sand, 1 kg of wood charcoal and brick chips* Bottom bucket: water collection container

The water first flows through the coarse river sand and a composite iron matrix (CIM). The water flows into a second bucket where it again filters through coarse river sand, then wood charcoal to remove organics, and finally through fine river sand and brick chips to remove fine particles and stabilize water flow. '''Kanchan Arsenic Filterfilter'''<br>
