In 2012, Haines City, Florida, installed BCR’s Neutralizer® system at its 3 MGD wastewater treatment plant to upgrade from Class B biosolids to a Class A/EQ fertilizer product. Following installation of the Neutralizer® solution, Haines City has experienced significant cost savings and expanded beneficial reuse options for its fertilizer product.
In 2012, the Haines City wastewater treatment plant, serving the City’s businesses and 20,000 residents, upgraded from its previous aerobic digestion operations to BCR’s Neutralizer® system. Previously, the plant treated secondary sludge through aerobic digestion and subsequently hauled the Class B residuals to a landfill or land application site.
Haines City faced several challenges, including escalating energy costs, odor issues, digester capacity issues, and stringent environmental regulations. In addition, the City faced limited financial resources and a lack of capital for process enhancements. After an evaluation process, Haines City installed the Neutralizer® system to address these challenges.
Neutralizer® is BCR’s patented Class A/EQ residuals treatment solution. This two-stage chemical system treats Waste Activated Sludge (WAS) and produces Class A/EQ residuals in a matter of hours. Neutralizer® is approved by the U.S. EPA as a Process to Further Reduce Pathogens (PFRP).
Neutralizer® has become the most installed Class A/EQ solution in Florida because it is simple, safe, environmentally responsible, and cost effective for wastewater treatment plants of almost any size.
BCR Provided Haines City with a design-build Neutralizer® biosolids treatment solution to upgrade to Class A/EQ residuals. The solution consisted of a dual-train Neutralizer® system with a centrifuge for sludge dewatering. Installation of the Neutralizer® system was completed in late 2011, and full-scale operations began in early 2012.
Through value engineering, BCR was able to deliver a solution that met Haines City’s objective of producing a Class A/EQ product while meeting the City’s financial goals.
After installing the Neutralizer® system, Haines City upgraded its end product from Class B biosolids to a Class A/EQ fertilizer. Haines City is in the process of registering its nutrient-rich Neutralizer® residuals as a commercial fertilizer with the Florida Department of Agriculture. Residuals are free from foul odors, and the pH can be adjusted to suit the needs of the fertilizer customers. Neutralizer® residuals meet the strict nutrient and pollutant limits of the State of Florida and have an extremely low Phosphorus Source Coefficient (a measurement of phosphorus leachability). In a study performed by Penn State University, the Phosphorus Source Coefficient of Neutralizer® residuals was 0.1.
The Haines City Neutralizer® project was supported by the media and the local community. See the following links to media coverage and talks given at the facility’s grand opening ceremony:
