The increasing application of constructed wetlands for leachate treatment
is an ever-growing incentive for the development of better process design tools.
This study was conducted to investigate leachate treatment performance of
horizontal subsurface flow constructed wetlands (HSSFCW) installed with water
dispersal system, called Safety Flow® to produce a defined subsurface wetting
pattern along the line and length of the system. A pilot scale HSSFCW with
three parallel reactors was set up with dimensions of 2.45 m length x 0.20 m
width x 0.40 m depth. All reactors were dosed using pre-treatment leachate
effluent from sanitary landfill, lohor Bahru. Out of the three reactors, Reactors
A and C were planted with I11yp/za angustifolia, whilst Reactor B was not
planted and used as a control. In addition, Reactor C was installed with water
dispersal system. The performance of constructed wetlands system was
evaluated from the effluent quality. The main parameters were organics matter
(biochemical oxygen demand (BOD) and chemical oxygen demand (COD),
nutrients (ammonical nitrogen (NH4-N), nitrate (N03-N), phosphorus (P), and
heavy metals (chromium (Cr) and cadmium (Cd). Based on the observation,
Reactor C was found better than both Reactors A and B. Reactor C had removed
more than 70% of BOD and COD, up to 80% of NH4-N and P and at least 90%
of heavy metals. |
