A cheese manufacturer with a 3 million gallon lagoon, discharges onto an adjacent meadow and has two 5hp splashers operating during the summer months. The task in this application is to eliminate odor and reduce BOD. One splasher near the discharge pipe has been replaced with the BIO-Boost™ System from TVT US Corp. The second splasher located at the far end of he lagoon remained for continued circulation and aeration. Typically the lagoon establishes an active green algae population during summer operations. During Winter operations the daily whey waste water simply is discharged into the lagoon system, which has enough capacity to retain all whey discharge until February/March. The collection tank in the factory has fluctuating BOD loadings from 3,860-10,600. The pH range in the collection tank is from 9.8-11.6, at this range no microbiology is present. The lagoon is covered by ice and at aeration start up in spring odor occurs. The BIO-Boost System was installed and for the first time no odor has been noted during summer operations. When the temperatures in the lagoon reached 55°F application specific bacteria where added. Dominant green algae have been replaced by the inserted bacteria and turned the lagoon into a secondary aerated treatment lagoon. The odor was eliminated within three weeks and the BOD was reduced by 73% over a few months. The existing alge dominated lagoon has been converted into a secondary treatment by the BIO-Boost System.
