Solar Desalination ‐ Leachate Treatment  Treatment of Leachate is a GLOBAL ISSUE
 Old disused rubbish tips
 New state of the Art landfills

Solar Desalination ‐ Leachate Treatment  F Cubed has developed the CAROCELL
 A flow through SOLAR DESALINTION SYSTEM
 Following the Natural Water Cycle

The production rate on average is 5 ltrs per M2/ Day
Completely solar driven with minimal maintenance
Modular design to meet any water volumes or area
Economics : if you are paying 0.20c per ltr for off site disposal the amortized Capital is less than 6 months.
disposal the amortized Capital is less than 6 months
 Operation life of 15 – 20 year before refurbishment.

Solar Desalination ‐ Leachate Treatment Solar Desalination ‐ Leachate Treatment  Solutions to the Ammonia transfer in the produced water
 1>To be filtered through ZEOLITE CLAY
 2> The double desalination of the produce water
 3> The application of using the produced water as a liquid fertilizer
7
Solar Desalination ‐ Leachate Treatment  1> ZEOLITE CLAY  The produced water is free from other contaminates, filtering this through the Zeolite Clay binds the ammonia within the clay structure which then can be used as a soil conditioner. Solar Desalination ‐ Leachate Treatment  2> Double Distillation , for older landfills will lower Ammonia Levels. ie Closed Local council landfills
 The processed water > Carocell unit flashing off the Ammonia in the distilled water , the waste stream has 9
90% reduction in Ammonia.
 Further diluted for road maintenance 8

 Trials undertaken by the Hanson Landfill team.
 The natural nitrogen cycle is used to denitrify the ammonia allowing the plants to take up the nitrogen and release nitrogen gas.
