Settle the dirt

If you have a swimming pool you need a sand filter to filter dirt from the water, and so it becomes dirty instead of the water. But, then you need to wash the sand in the filter, with clean water from your pool. That water is normally disposed of. As we had a LOT of sand in the pool lately, the filter could not cope, so we resorted to a 500 liter settling tank, that we just pumped the dirty water in, directly, bypassing the filter. Let it settle a day or two, and siphon it back. That way we don’t lose water, and no salt. Just the last 30 liters plus sediment we washed away after about 10 settlings.

From now on we won’t dispose of water any more, and always wash the filter this way.

Yet another ingenieur Jansen triumph!
