To prepare a cleaning solution when using untreated raw water, it is important to know the water
chemistry. We recommend using water that has been filtered and de-chlorinated. We recommend
using de-ionized water for cleaning if possible. We also recommend paying attention to sparingly
soluble compounds of Ca, Mg, Fe, Al, etc. and insoluble silica, SiO
2
.These elements can
precipitate onto the membrane when there is a pH shift in the water.
