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.


Summary of preliminary results
