Biosolids Management Site
The Biosolids Management Site (formerly known as the Farm Site, or Land Application Site) sits on 670 acres of Midland Bermuda fields and operational facilities that adjoin the Paul R. Noland WWTP property. The new name was given to accommodate the recent addition of a large-scale biosolids drying operation.
NUTRIENT UPTAKE PROGRAM:
The property at the Biosolids Management Site is managed to provide nutrient uptake of phosphorous in the soil from past land application of biosolids. Phosphorous uptake is achieved through effluent discharge mitigation, which supports the growth of grass. The grass is then cut, harvested as hay, and sold to local residents and farmers. Price is primarily determined by market supply/demand and the quality of the hay.
Advertisements are placed in the local paper around mid-March each year for those interested in securing a place on the hay commitment list. In addition, an official notice is sent to previous customers detailing when hay can be reserved. This year's hay commitment letter can be found here.
BIOSOLIDS DRYING OPERATION:
Escalating landfill costs and concern about future environmental impact have caused the City of Fayetteville to invest in other sustainable alternatives for biosolids disposal. A two-phase project to address these issues began in July 2010 with approval from the City Council for the installation of six Parkson Thermo-System Active Solar Dryers. The solar drying houses are designed to use the sun for approximately 95% of the energy required to dry the biosolids; the end result is a significant reduction in the volume of this material being hauled to the landfill.
Operation of the Parkson solar drying houses began May 12, 2011. In the short span of time since start-up of these units, the results from implementing this system have been outstanding. For example, five truckloads of undried biosolids were reduced to one truckload of material after going through the drying process!
The second phase began in early 2012, the addition of a thermal gas dryer. Processing the material in this manner further improves the quality of the final product (Class A biosolids) and creates a sustainable alternative to disposal through beneficial reuse applications (such as soil enhancement), which is also sold to farmers and residents. This year's fertilizer commitment letter can be found here.
