This clip is to improve the water filtration system that has deteriorated from long use. by using the principle of stopping the flow of water instead of the old system that just slows the flow By using a timer to stop the water supply and alum for 3 hours to allow the cloudy water to settle in the sedimentation pond as much as possible. so that the filter can be used for a long time without having to wash the sand filter often Because this system is an underground water filtration system that doesn't have groundwater, therefore uses raw surface water, Huai water instead. Finally, I would like my friends to come up with an idea of ​​the principle of stopping this water flow to use to create a filtering system for turbid water to be clear water to produce tap water for use in Low capital is self-reliance. But if you still don't understand, just wait for the clip Next time I'm going to make it at home. Timer DH48S -S https://www.lazada.co.th/products/i32...
