53. Question..
 When last did you test and evaluated filter products?
 By changing media from PP to GF, increase life by 24%
 Determined the exact PSD of the process? Will extend
the life, it block prematurely.
 Dual filtration extends life of fine filters and save a
huge amount of money
 Sand and self-cleaning filters does not work, it
is hugely inefficient.
