In granular activated carbon filters for drinking water, contact times from 8 to 12 minutes are recommended, for bed heights of minimum 1m and a superficial speed of 12 m/h.
Toensure a longer life and optimal performance of granular activated carbon, the water that reaches the filters should have the minimum amount of solids in suspension as possible. Therefore a previous filtration is recommended.
Where possible it is also recommended to make a previous ozonisation of the carbon filters.
