7 steps to choose the water filter cartridges for liquid filter housing
1) The requirements for filtering water. Firtly, we should know what’s our requirments for the water after filtration? Then we can choose the filter cartridges to pre filtration or deep filtration? To reach a effective filtration and the cost budget.
2) The sequence for the filter cartridge filtration accuracy: if we have 2 stage or 3 stage filtration process, we should choose the filtration accuracy from bigger to smaller, for example, from 50 microns, to 20 microns, and last stage should be 10 or 5 microns.
3) The maximum working pressure, different kinds of filter cartridges material will have different working pressure capability.
4) The maximum working temperature.
5) The requirements for the flow rate per hour.
6) The result for the liquid filtering, is it for municipal tap water use? Or for medical use? Or for drinking water?
7) Whether the liquid contains a strong acid or strong alkali.
