How it works
The SWS-200 solar water still is of a "wick" design, meaning that it works by
having the input source water slowly and continuously wet a black cloth wick. The
sun shines through the front glass pane and heats up the wick, to the point where
water evaporates from it and rises up to the pane where it condenses. The
condensed distilled water runs down the glass pane into a trough where it then runs
out of the still and into a carboy.
Water is fed into the still by way of 1/4" tubing coming from a hose faucet. The
water pressure in this line is set to 10 psi by a regulator located at the faucet. The
flow rate of water is set by the main valve of the still. Water is evenly distributed
on the wick by a manifold inside the still, this manifold being 1/4" tubing with a
series of small pin holes.
After exiting the still and before entering the carboy, the distilled water passes
through a granular activated carbon (GAC) post-filter, in order to remove any
residual organic volatiles. The water finally entering the carboy is highly purified
and ready for drinking as is, or may be remineralized if desired.
