Biosolids Scrubber Used in Renewable Energy Production
A sludge processing facility in Southern California produces cement kiln fuel from waste sludge, a renewable source of energy. The dryer exhaust contains ammonia, particulate, sulfur compounds, and water vapor. The Envitech biosolids scrubber condenses the water vapor and captures the pollutants, enabling the plant to meet tough California regulatory requirements for SOx, NOx, and particulate. The majority of the exhaust is recycled to the dryer. This allows the downstream RTO to be smaller, resulting in both capital and operating cost savings.
The Envitech biosolids scrubber is a combination of air pollution control system components which include a quencher, condenser/absorber tower, Venturi scrubber, and packed tower scrubber. Simultaneous condensing of water vapor and pollutant removal enables the exhaust to be recycled to the dryer while at the same time enabling the plant to meet tough California regulatory requirements for SOx, NOx and particulate.
