Case: Fish Blood Pond – Tasmania
Problem: This facilities at Huon Aquaculture was having problems with
odour control management. For some time

emanating from The Blood Ponds at Hideaway Bay. These ponds are utilized to
capture and treat wash down waste water and blood generated from the harvest of
Atlantic salmon at Huon aquacultures Harvest facility located on the shore of
the Huon River at Hideaway Bay. Huon Aquaculture endeavored to reduce the

Case: Hog Facility – Texas
Problem: This facility was having problems with manure crusting and
floating on the top of the pit. This was making it impossible to flush the
solids from the pit to an anaerobic digester. It was also having a tremendous
buildup of ammonia gas that was causing irritation to the pigs and the
employees. Flies were beginning to use the crusting manure as a breeding ground
which was also creating problems for the pigs and employees.
Case: Dairy Farm – New Mexico
Problem: This facility has an expensive liner in its lagoon, and the use
of equipment to remove the solids from the lagoon was not an option. It also
dewaters the lagoon via irrigation onto row crops every 30 days. The buildup of

Case: Dairy Farm – Crosswinds
Problem: Buildup of sludge in this 12 year old lagoon has been a

problem involved the clogging of the irrigation nozzles by the sludge during
dewatering resulting in interruptions and manual cleaning.
Case: Dairy Farm – Oklahoma
Problem: This facility was in need of solid removal from sediment basin
as it was to a point of water flow restriction and solid capacity in the
sediment basin. The expectation was to liquefy the solids in the sediment
basins using microbial augmentation, and to not use costly equipment to do so.
Further expectation was to increase wastewater flow to the lagoon for
