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. BioWorld 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.

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. BioWorld 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.

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 BioWorld Waste & Odor Treatment in conjunction with agitation, the solids had been significantly reduced, odors were eliminated, and aerobic digestion was established.
