Maintenance
There are some maintenance tasks you’ll need to carry out in order to keep your
SWS-200 solar water still performing optimally. Here are the tasks, ordered from
most to least frequent:
Cleaning the glass pane
The outside surface of the glass pane of the still will accumulate dirt and bug/bird
droppings over time. Clean it in the same way you clean your house or car
windows. For a streak-free window, as a final step try using a microfiber cloth
such as “E-Cloth” with distilled water.
Replacing the GAC
The GAC (granular activated carbon) in the post-filter periodically must be
replaced, especially if you begin to notice a slight taste to the distilled water. The
best GAC to use for filtering small organic volatiles is made from coconut husk.
Inexpensive bags of coconut husk GAC can be ordered online, for example
through Amazon.
The post-filter is easily removed from the barb fittings on either side. Shake out
the old GAC (can go on compost pile), and pour in new material. Note there are
mesh screens on either side to contain the GAC. Put enough GAC in to allow for a
tight fit. Pour some water through before closing it up, to ensure all the carbon
grains are wetted and to wash out any small grains. The two barbs on either side
should be pushed in firmly, so the GAC is well-packed in the tube.
Cleaning the wick
Over time, depending on the mineral content of the source water, the wick will
calcify and accumulate other sediment build-up. This degrades the performance,
because such sediment is less solar absorptive than a clean black wick.
To clean the wick, first turn off the water mains faucet. Next, cut the 1/4
″
drip
irrigation tubing near the main valve of the still. Try to make a clean cut, because
you’ll later re-attach the tubing to the barb of the valve. Remove the small piece of
