Like many wastewater treatment facilities across the country, Joint Meeting of Essex and Union Counties (JMEUC), an 85 MGD facility, was looking to increase their digester gas production. They were introduced to BAE, and a protocol was developed to feed the digesters at a rate of 27 gallons per day. After extensive analysis, not only did JMEUC benefit from a 41% increase in digester gas production and the cost avoidance of electrical energy as a result, but they also reduced the amount for sludge cake for removal and significantly decreased the amount of TSS returned to treatment.  

The result is a net annual savings of $402,000.

It is also projected that as the JMEUC brings its 4th digester back into service, the facility will benefit from even greater savings as a result of additional power production and impacts to solids handling processes and disposal.

The Gloucester County Utilities Authority (GCUA) WWTP provides service to 15 municipalities with approximately 207,000 residents, covering a total service area of 150 square miles. GCUA is currently permitted to treat 24.1 MGD, and the plant treats leachate from the local landfill as well as septage that is hauled to the plant. GCUA began using BAE to restore balance to the microbial environment after significant rainfall depleted plant biology and caused numerous operational upsets. Within a matter of days, the system was in full recovery. Taking a proactive approach, GCUA continued using BAE as a regular maintenance tool to strengthen plant biology. Soon after, the facility began experiencing several operational benefits, resulting in a net annual savings of over $360,000.

BAE has been an invaluable tool for our WWTP, increasing our biogas production for reuse onsite and decreasing our energy demand on utilities. I’d highly recommend BAE to fellow wastewater treatment professionals.

Since implementing the use of BAE® in the digester, Landis Sewerage Authority (LSA) has vastly improved not only digester performance, but also increased the efficiency of the CHP system. The EPA recognized the results of this outstanding performance and awarded LSA with the EPA 2010 ENERGY STAR Award.

Hayward Water Pollution Control Facility (HWPCF) treats an average dry weather daily flow of 11.9 MGD, with peak daily flows averaging 18.5 MGD. An independent third party was brought in to validate the benefits of BAE® and perform an in depth review of the data and relative equipment. All inconsistencies were taken into account and extracted from the provided data. The resulting conclusion shows a positive effect. The addition of 6 gallons per day of BAE® from May 23, 2011 to December 31, 2011 significantly increased the production of biogas by 36%, which in turn resulted in an increase of kWh generated on-site by the engines. In addition, a substantial decrease in volatile solids was noted.

Lewistown WWTP had a particular challenge during heavy rain events, which included the possible loss of solids from the final clarifiers due to high plant influent flow conditions. Filamentous bacteria had overwhelmed the facility's biology during late winter and early spring as the wastewater temperature began to increase. To compensate for the possible loss of solids, polymer was added to the secondary clarifiers, and bacteria were added to the primary clarifier effluent. At the conclusion of the 60 day cycle, both polymer and bacteria were discontinued, and the microorganism population was in complete order.

The Cumberland County Utility Authority (CCUA) began using BAE in their primary anaerobic digester because they were having difficulty maintaining the minimum volatile solids destruction (VSD) of 38% required by the NJDEP for land applying sludge. 

BAE had clearly demonstrated that a balance between the acid formers and methane formers had been created and a stimulating effect was taking place within the primary digester, improving the performance of the two-stage secondary digester. Dewatering by the plants centrifuge machine improved, receiving digested sludge as high as 6% creating a dewatered cake at 25 to 28%.
