The natural pumice and bovine hydroxyapatite powders were grounded and sieved separately to achieve a mean grain size of ~100 µm. The HA powder was then mixed with 5 and 10 wt% of NP powder, respectively. The samples will be further denominated as 5 wt% NP-BHA and 10 wt% NP-BHA. Each mixture was then further grounded for 4 h in the ball mill.
Pumice Filtration Media is a low-density media typically used in multi-media filters to enhance the capacity of the filter and to remove smaller micron particles. Pumice sits as the top layer in a multi-media filter and is widely used for pre-treatment in desalination and seawater reverse osmosis plants (SWRO).
