. Water enters prefilter. Sand, silt and other sediments are reduced. Chlorine is also reduced. See Fig. 27.
2

3
. Water enters the Reverse Osmosis membrane. Dissolved solids are reduced.
4
. Processed water leaves the Reverse Osmosis Membrane and flows to the storage tank.
5
. Drain water with dissolved solids leaves the Reverse Osmosis membrane and flows to the drain.
6
. Faucet is activated.
