• -->> cont: WM Accepted: L(Drinking water production): Slow Sand Filter(SSF) by biofilm
effect(schmutzdecke):
Its high effectiveness in removing heavy metal to undesired bacteria is not fully WM explained.
*Also effective as activated sludge combined waste water treatment is now becoming underutilized
status on new installation basis, replaced by another bio process MBR(Membrane
BioReactor).
• Given established economic system, more suitable to install new in poor nations with low cost
land that doesn't disrupt local overall business structure. With mechanical sand cleaning system,
low cost labour is no longer essential. Cost competitiveness diminishes in long freezing season
area(BioSand Filter - Manz Engineering, Bushproof, South Asia Pure Water Initiative+), Often
due to low profitability(too cheap) notable NGOs handling rather than prv companies(similar
phenomena to solar desalination or atmospheric water collector)(DHAN Vayalagam
foundation+), but some eco conscious Western companies are taking up again(Osmo Sistemi+)
• J(waste water cleaning): effect in sludge digestion by some high aeration methods has
WM media occasionally Disputed portion as to whether non-conventional aeration
methods are much more effective than regular aeration types. In certain applications/
situations some are reported to demonstrate disruptively increased effectiveness in following
types: Spiral aerator type(Pax Water Technologies+), Z(bioenhancement, extra plant growth)
(Seair inc+)
