How to make filtersOur school requires a filter to clean out the dirty waterI don't know what to do. Please consult me ~!
Find a plastic box and open itThen under the "bottom" uniform gash. Hole can not be too wide (that way, water is too easy to leak down hole) not too narrow (in that case, the water is not easy to drain down), inside the box, some filter cotton on top (if not using space cotton will do it) and have a certain thickness. In addition, conditions permitting, you can also put some activated carbon in the middle of the filter, so better.A hole is placed at the side of the box close to the opening, and a plastic tube is drawn in (for water injection into the box). The other end of the plastic pipe is connected to the pump
Be careful：The pebble, sand wash, small pebbles and quartz sand filtration effect.Activated carbon should be washed to soften the role of water quality.A filter gauze or filter cotton can be arranged at the outlet of the unfiltered water to filter out larger impurities, and also to be replaced and cleaned at the same time.
