Large amounts of aluminum hydroxide (Al(OH)3) exist in water purification sludge (WPS) because of the added aluminum coagulant in water treatment process. Notably, Al(OH)3 is an amphoteric compound, can be dissolved in its basic condition using sodiu

The reduction of Cr(VI) by the nZVI particles seriously depends on not only the nZVI dosages but also the surface characteristics of nZVI particles caused by different syntheses processes. Therefore, to control the nZVI process only based on the nZVI

The major method used for the recovery of aluminum from water purification sludge is through acidification or alkalization, however, the cost of the acid and alkali limits the amount available for use, and thus results in the low concentration of dis

Black carbons (BC) which result from the incomplete combustion of farm waste [man-made (burned) BC] are highly absorbent. In Taiwan, the burning of farm waste known as slash and burn is common. The BCs from the burning may present an environmental ch
