Evaluation of Physicochemical Pretreatment Methods on COD and Ammonia Removal from Landfill Leachate
The goal of this experiment is to evaluate the
effectiveness of different leachate pre-treatment options in terms of
COD and ammonia removal. This research focused on the evaluation
of physical-chemical methods for pre-treatment of leachate that
would be effective and rapid in order to satisfy the requirements of
the sewer discharge by-laws. The four pre-treatment options
evaluated were: air stripping, chemical coagulation, electrocoagulation
and advanced oxidation with sodium ferrate. Chemical
coagulation reported the best COD removal rate at 43%, compared to
18% for both air stripping and electro-coagulation, and 20% for
oxidation with sodium ferrate. On the other hand, air stripping was
far superior to the other treatment options in terms of ammonia
removal with 86%. Oxidation with sodium ferrate reached only 16%,
while chemical coagulation and electro-coagulation removed less
than 10%. When combined, air stripping and chemical coagulation
removed up to 50% COD and 85% ammonia.
