Log credits for giardia removal
(OP)
Has anyone ever seen any documentation suggesting that filtration with a manganese greensand media removes giardia?
In addition, does anyone know of any jurisdiction (state/ province, etc) that recoginizes the above?
Thanks in advance for your information

Sometimes credit is given when chemicals are used, but optimization of doses and flow rates is more difficult with a pressure filter because the operator can not see the outcome of the dose rates on the media bed, so the credit are typically less than the credit given for a traditional gravity filter with equal componets.
