The Dairy Science Department of a California University milks 250 cows. The
wastewater and manure lane flushes through a solids separator and into a lagoon.
An enzyme-based product was used in an attempt to digest solids and reduce
odors. However, the wastewater odor continued to generate complaints from
professors, students, physicians and attorneys. Advanced BioTech Waste & Odor
Treatment was added to the lagoon every 2 weeks. The odors have been eliminated
and the solids are continuing to be digested aerobically. The staff has received
numerous compliments for resolving the odor problem.
Project Summary #2 (Dairy Wastewater Solids Digested)
A California dairy milks 1,050 cows 3 times a day. The resulting wastewater
and manure is lane flushed into a lagoon. The lagoon became heavy with solids,
had a two inch crust, and odor problems. Advanced BioTech Waste & Odor Treatment was
added to the lagoon every 2 weeks. After 8 weeks of treatment, the solids and
two inch crust layer had been digested and odors were eliminated. On-going
treatments are maintaining the lagoon odor free with ducks inhabiting the area.
Project Summary #3 (Fats and Grease Digested at Meat Processor-Odor
A California beef slaughterhouse generates 1 million gallons per day of
wastewater containing animal fats and grease which empties into several lagoons.
An enzyme-based product was used for several years in an attempt to digest
solids and reduce odors, but limited success was observed. The influent lagoon
was anaerobic and several feet thick with grease and fats. After 6-8 months of
biweekly Advanced BioTech Waste & Odor Treatment in conjunction with agitation, the
solids had been significantly reduced, odors were eliminated, and aerobic
digestion was established.
