continued 4: Aeration & Aerobic Bacteria 4
• -->cont: WM Accepted widely used effects: J(waste water cleaning): Membrane
BioReactor(MBR):
In addition to smaller tank, 20-30% less energy use & low CAPEX by aerobic granular
sludge generating quicker setting(Royal HaskoningDHV Nereda): initiated by Delft
Univ.(There is slight disputing on effectiveness at media level)
• Although some universities in West pioneer new water technology
commercialization, This group from Netherlands has most frequently been the
driving force of bringing in previous pseudoscience into WM as science legal effects.
Often when they publish western unapproved but non western nations granted
effects, suddenly it becomes "discovered" & other western scientists can officially
start studying it for the first time.
• L(Drinking water production): Slow Sand Filter(SSF) by biofilm
effect(schmutzdecke) has been long used as very effective low cost method with
essentially only cost is occasional sand cleaning. Mostly replaced by "new
conventional" methods since around 1950s by exaggerated media ineffectiveness
appeal, lack of profitability (when this system is sold compared to other mechanical-
chemical types) & short term land sales profit in low cost land area, and genuinely
higher cost in super high land cost area.
