Preliminary Outcomes
Anaerobic Dam
BiOWiSH™-Manure & Odor TreatmentreducedthestrengthofeffluentwaterintheAnaerobicdamby83%.
Prior to Treatment 20 July 2009
After Treatment 10 September 2009
% Reduction
TotalSuspendedSolids(mg/L) 1,050 200 81%
BOD(mg/L) 2,700 450 83%
Nitrogen(mg/L) 590 470 20%
Prior to application of BiOWiSH™ – Little or no
sign of activity within the dam. High BOD, TSS
and Total Sludge Content.
Following application of BiOWiSH™ – Very
noticeable bubbling and sludge reactivation,
causing slick on dam surface. Substantially lower
BOD, TSS and Sludge Content. This will continue
until sludge has been completely degraded.

1,300Gal (5,000L) fresh water tank, prior to the application of
BiOWiSH™, showing inlet (far left, with float / ball valve) and linked
sections, all with moderate to severe algal growth on the surface of
the water.
Following the application of BiOWiSH™, the high
nutrient levels have been reduced to the point where
algal growth is inhibited. The fresh water used for
washing down is now clean and clear, with very little
algae.
