© 2005 STS WMH The following pictures show the progress of the test conducted September 28, The test was to see the effects of pumping directly on to a flat surface (on-site spread) and if the resulting effluent setup the same as it does in a dump truck box (hauling for landfill cover). The approx. total amount of the fluid was 4500 us gal Aprox. run time 57 min. (start time 11:06 end time 11:59) Average flow 79 gpm. Test was successful! HDD PIT DRY Test Sept 28/05

© 2005 STS WMH Summary In approximately one hour, approximately 4,500 gal (US) (17 cubic meters, or 22 cubic yards) were processed and mixed with reagents which resulted in stackable solids which could be site spread or hauled away to a landfill in a dump truck. In approximately one hour, approximately 4,500 gal (US) (17 cubic meters, or 22 cubic yards) were processed and mixed with reagents which resulted in stackable solids which could be site spread or hauled away to a landfill in a dump truck. The reagents combine with the water and spent mud to trap and bind contaminating constituents thus making them non-hazardous.

Output solid met all Ontario disposal requirements – considered dirt – spreadable/disposable anywhere Output solid met all Ontario disposal requirements – considered dirt – spreadable/disposable anywhere
© 2005 STS WMH Conclusion This test has shown that we can turn waste drilling fluids and residue to environmentally compliant transportable/land disposable solids, using a simple robust method (equipment, reagents, and process) thereby eliminating problems/costs with current waste fluid disposal methods.
