..., 2010) and this can lead to problems if the phosphate in the desorbed solution is to be recovered or used for fertilizing and irrigating crops due to the risk of high salinity (Johir et al., 2011)....

...This issue can be overcome by using prefilters to remove suspended solids and organic matter (Chazarenc et al., 2007; Johir et al., 2011), using large sized media (Shilton et al., 2006) or using a mixture of fine sized media (to have high sorption capacity) and coarser sized media (to reduce…...

...Simple low-cost salts such as NaCl and KCl have proved to be successful in desorbing phosphate only from sorbents with weak sorption strength where the sorption mechanism is nonspecific (ion exchange or outersphere complexation; Johir et al., 2011; Xu et al., 2010; Xu et al., 2011)....

...However, high salinity may be retained in the desorption solution, meaning that the phosphate recovery from the solution or direct land application of the solution may be ineffective (Johir et al., 2011)....
