CNP - Technology Water and Biosolids Corporation demonstrated how AirPrex technology has helped Biological Phosphorus Removal wastewater treatment plants improve overall plant efficiencies and in many cases save hundreds of thousands of dollars per year.
AirPrex, a sludge optimization and phosphorus recovery system, simultaneously helps wastewater treatment plants to optimize their sludge treatment processes and cost-effectively reduce problematic struvite buildup, resulting in overall plant efficiencies and significant operational cost savings. The breakthrough process also produces a high-phosphate fertilizer that can serve as a revenue source for treatment plants.
AirPrex serves as a complete biosolids optimization and phosphorus recovery process that takes place after a plant’s anaerobic digestion process but before sludge dewatering.
Efficiencies gained result in the ability to:
• Reduce the need for polymer and associated costs by as much as 30 percent.
• Improve sludge dewaterability for drier cake solids, which in turn, cuts biosolids disposal costs by as much as 20 percent.
• Minimize pipe treatment and repairs, effectively lowering costs for maintenance by as much as 50 percent.
• Potentially increase revenue by as much as 10 percent with the ability to resell the high-phosphate dry solids as fertilizer.
