The treatment plant is now working with Neozyme to reduce and condition sludge and expand the use of Neozyme within the wastewater facility. This plant uses an activated sludge process with wasted sludge process with wasted sludge returned to the primary settling tank. Sludge remaining after wastewater treatment is treated by anaerobic digestion to produce methane gas. The specific goal of this trial was to reduce concentrations of both odor causing chemicals and nitrogen in a waste treatment lagoon receiving wastes from approximately 20,000 swine. The lagoon has a maximum capacity of approximately 29 million gallons and has been operated for several years.
Fresh water is used for flushing.
To determine the effectiveness of ESP treatment, samples of the wastewater leaving the lagoon were collected for analysis and compared to historical data. The interim results of this study confirm ESP is having the desired effect of reducing both odor and total nitrogen levels in the treated lagoon. It is anticipated that as treatment continues, allowing for the further degradation of accumulated nitrogen sources in the sludge, total nitrogen concentration will be further reduced.
