• -->>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 萬年清環境工程股份有限公司 +).
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.
