Separating sand and salt by filtering and evaporation ...

Procedure. Pour the sand–salt mixture into the beaker so that it just covers the base. Add about 50 cm 3 of water, or add water until the beaker is about one-fifth full. Stir the mixture gently for a few minutes. Filter the mixture into a conical flask. Pour the filtrate into an evaporating basin.How to measure sand filter? - Trouble Free Pool · I would suggest that you size the filter based on the pump. I suggest finding the flow rate of the pump at 20 ft of head, then using the following equation. √ (F x 3.05) = radius of filter in inches. For example if the flow is 60 gpm at 20 feet of head. √ (60 x 3.05) = 13.5 inches radius or about 27 inches diameter.
