Abstract |
A proposed program has been selected to serve the sludge management needs of the City of Los Angeles, Los Angeles County Sanitation Districts, and Orange County Sanitation Districts. The proposed program provides for complete cessation of ocean discharge of sludge and recovery of useable resources from the sludge. For the City of Los Angeles, a system of dehydration and thermal processing for volume reduction and energy recovery has been selected. For the Los Angeles County Sanitation Districts, a combination of dehydration and thermal processing for volume reduction and energy recovery, advanced windrow composting and recycling, and landfill disposal of sludge has been selected. Truck transport of dewatered sludge to an offsite location for composting/air drying has been selected for the Orange County Sanitation Districts. |
