(P) and potassium (K) are non-renewable materials and </span><span style=\"font-family:Verdana;\">widely</span><span style=\"font-family:Verdana;\"> in many industries such as </span><span style=\"font-family:Verdana;\">agricultural</span> <span style=\"font-family:Verdana;\">sectors</span><span style=\"font-family:Verdana;\">. On the other hand, the demand </span><span style=\"font-family:Verdana;\">of</span><span style=\"font-family:Verdana;\"> P and K as fertilizers increases which
following </span><span style=\"font-family:Verdana;\">global</span><span style=\"font-family:Verdana;\"> population. </span><span><span style=\"font-family:Verdana;\">The nutrient source of P and K which get from
biomass waste &lt;i&gt;</span><i><span style=\"font-family:Verdana;\">i.e.&lt;/i&gt;</span></i><span style=\"font-family:Verdana;\"> incinerated </span><span style=\"font-family:Verdana;\">of</span><span style=\"font-family:Verdana;\"> activated sludge and
coffee husk biochar, respectively. The present study was conducted recovery of
P and K as struvite-K (KMgPO</span><sub><span style=\"font-family:Verdana;\">4</span></sub><span style=\"font-family:Verdana;\">&amp;middot;6H</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">O)
precipitates. The results showed that alu</span></span><span><span style=\"font-family:Verdana;\">minium was released simultaneously with P from incinerated activated
sludge with precipitate of Al:P of 1:1, K:P of 0.5, and Mg:P of 3. However,
aluminium was inhibited to form struvite-K. Then, we examined cation removal
especially for removed Al by dissolved 0.5 M HNO</span><sub><span style=\"font-family:Verdana;\">3</span></sub><span style=\"font-family:Verdana;\"> and the solution was
mixed with KH</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">PO</span><sub><span style=\"font-family:Verdana;\">4</span></sub><span style=\"font-family:Verdana;\"> and MgCl</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">&amp;middot;6H</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">O
as </span><span style=\"font-family:Verdana;\">source</span><span style=\"font-family:Verdana;\"> of K and Mg, respectively. The
results showed a</span></span><span style=\"font-family:Verdana;\">luminium (Al)</span></span><span> </span></span><span><span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">was removed with precipitate K:P of 0.5, and
