Biosolids Processing Facility
The SWA accepts up to 600 tons per day of biosolids from almost all of the local wastewater treatment facilities in Palm Beach County at the BPF. This includes: the City of Boca Raton, East Central Regional Water Reclamation Facility, Loxahatchee River District, Palm Beach County Water Utilities Department, Seacoast Utility Authority and South Central Regional Wastewater Treatment Facility.
The BPF is designed to use landfill gas as its primary fuel source. By using landfill gas to fuel the dryers, we save over $30/ton on processing costs. This also reduces greenhouse gas emissions by offsetting natural gas usage.
The facility is equipped with sophisticated air pollution control equipment that eliminates odor causing vapors generated during the drying process.
The finished product is a small pellet, roughly 1 to 4 mm in size. The pellets are sold to companies as a "green" fertilizer product, all created from something that used to be considered a waste.
For more information on the drying process and how the air is handled and treated, process flow diagrams are provided here:
BPF Receving Area
Trucks back into the receiving area to drop off the wet biosolids for processing.
Truck Making a Delivery
Here, a truck is offloading wet biosolids from one of our local wastewater treatment facilities into receiving bins where it is then transported for storage and treatment in the drying system.
This is a view of the processing room, looking towards the screeners and recycle bins. There are two processing trains that can dry over 25 tons per hour of wet incoming biosolids.
The screener separates the final product from the material that is too large and too small. Anything that is not the right size is recycled back into the process.
Rear View of Facility
This is the rear of the facility, where you can see the Regenerative Thermal Oxidizers (RTOs) and the cooling towers.
Final Product (Pellets)
The finished product is a small pellet, about the size of Nerds(r) candy.
LFG Compression Skid
The primary heat source for the BPF comes from landfill gas (LFG) generated at the nearby SWA Landfill. This LFG skid cleans and compresses the gas before sending it to the BPF.
