This is a landfill leachate treatment system for leachate from an existing county landfill

1. Average Temperatures - January 1C and July 23C
2. Average Annual Precipitation - 35 inches
3. Design Flow - 5,000 gpd
4. Project Location - Monroe County, IN near Bloomington, IN
5. Restrictions - System must provide treatment for 50 years.

DESIGN OBJECTIVES - Meet Indiana water quality standards for BOD, TSS, nitrogen, metals and be capable of treating leachate for fifty years.

1. Provide an On-Site Treatment System - Meet Indiana water quality standards for BOD, TSS, nitrogen, metals and be capable of treating leachate for fifty years.
2. Provide for Zero Discharge of Treated Effluent - Treated leachate can no longer be discharged into surface waters.
3. Provide Long Term Treatment of Leachate Solids - System includes reed beds designed for the removal of leachate solids and in-situ treatment.
4. Provide Treatment for Nitrogen -Treatment of nitrogen includes denitrification, plant uptake and harvest.

BENEFITS

• Extremely Low O&M Costs.
• Self maintaining and self regulating except for recycling pumps.
• Expansion Capacity - System can be easily expanded to accommodate landfill growth.
• Low Capital Cost.
• Ability to handle variations in design flows and loading rates.
• Ability to remove metals from leachate, and to biologically degrade priority pollutants.
