eachate originating from landfills poses a significant
environmental threat to both the groundwater and surface
water. In order to reuse it for irrigation, the leachate has to be
collected and treated in a proper way. In this study, leachate
samples were collected fromaworking landfill in Kuwait. Aerobic/
anoxic (A/A) biological reactors were used to treat the collected
leachate. The analysis of leachate show high solids content and
high organic strength as expressed by its biochemical oxygen
demand (BOD) and chemical oxygen demand (COD). The
maximum COD concentration was 800 mg/l and the maximum
total dissolved solids (TDS) concentration was 24000 mg/l.
The biological treatment of leachate was efficient for removal
of organic compounds. The COD removal efficiency reached a
value of 90% within a month. Nitrification rate was higher than
dentrification processes. The nintrate concentration in the reactor
decreased from a maximum value of 750 mg nitrate-N/L to a
minimum of 300 mg nitrate-N/L in 20 days. In general the A/A
treatment process has high efficiency in treatment of COD, solids,
and ammonia concentrations.
