<br /> Biosolids Handling Alternatives
<br /> • Construct a Heat Drying Facility
<br /> — Small Footprint
<br /> — Produces Class A Biosolids
<br /> — Reduces Volume Required for Land Application
<br /> — High Capital Cost
<br /> — Higher Operating Cost
<br /> • Expand Anaerobic Digestion System
<br /> — Extremely Large Footprint
<br /> — Requires Large Biosolids Storage Volume
<br /> — Large Quantity of Biosolids to be Land Applied
<br /> — High Capital Costs
<br /> — Not Practical Given the Land Constraints of the Site
