• -->>cont: b-Fluidized Bed Crystallization(FBC)/Pellet Reactor:
• ■Unlisted effect(Resource or toxin, heavy metal recovery): in addition to water
softening purpose, FBC's ability to crystallize solutes in water is used for wastewater
cleaning combined with resource recovery. This method often deploys chemical
dosage, but some companies can use cleantech method of non chemical dose or it
is all recovered for reuse hence no effluent is produced(Century Water Systems,
Ever-clear 萬年年清環境⼯工程股份有限公司 +).
Phosphorus Recovery: (Royal HaskoningDHV - Crystalactor+), add magnesium
dosed for crystallization of phosphorus but all recovered for fertilizer use (Mitsubishi
Kakoki, PHOSNIX - Hitachi Zosen+), But unlike other processes, for this purpose,
there are many innovative method that must always use low dose chemical/polymer
for flocculation(hence not covered in this research) that are as or in some cases more
effective/lower cost.
• P(Sludge reduction), S(separation of waste & toxin): as a result this enables
separation of unprocess-able elements, & reduces sludge to be handled at rest of
wastewater process & make more entire system to function more effectively
(particularly Anaerobic Digestion) by providing concentrated sludge feedstock.
