PALM OIL MILL EFFLUENT TREATMENT PLANT
SP 9000 is designed specifically for POME treatment at the systems below
to reduce BOD, COD, Fats, Oil and Grease efficiently and cost effectively.
Palm Oil Mill Effluent (POME) Treatment plants cater all raw effluent produced.
Approximately 0.65 tonnes of raw POME is produced for every ton of fresh fruit
bunches (FFB) processed. In 2003, a total of 2,106,956 tonnes of FFB were
processed, resulting in 1,369,521 tonnes of POME being produced.
Palm Oil Effuent Treatment Systems
Anaerobic Digestion System
Generally, palm oil mill effluent treatment plants (ETPs) are operated on two–phase
anaerobic digestion process followed by extended aeration process. This two-phase
anaerobic process gives excellent pollutant destruction efficiency of above 95%
while extended aeration ensures that the final pollutant levels in the effluent are
within the stipulated limits set by the Department of Environment (DOE).
In the anaerobic digestion process,
the raw POME is first converted into volatile
fatty acids by acid forming bacteria. The volatile acids are then converted into
methane and carbon dioxide.
The advantages of anaerobic digestion
system are:
1. The two phase system allows
greater control of digester
environmental conditions.
2. Long solid retention times allow
better biodegradation
efficiencies.
3. Additional settling of liquor
ensures minimum loading to the
aerobic process.
4. There is capability to cope with
full effluent load, regardless of
fluctuation
Extended Aerobic Process
In the extended aerobic system, the
anaerobic liquor is aerated to further
reduce the BOD content. In addition to
providing oxygen, the floating aerators
also ensure complete mixing is
achieved and the pod contents are
always in suspension. In this process,
levels of beneficial micro-organisms
are increased which in turn hasten the
conversion of pollutants into carbon
dioxide, water and energy. The aerobic
suspension is allowed to settle in a
settling tank to ensure production of a
fairly clean supernatant.
The main advantages of extended
aerobics systems are its high BOD
removal efficiency and low solid yield.
Ponding System
The raw effluent is treated using a
ponding system comprising of three
phases, i.e. anaerobic, facultative, and
algae processes. Although the system
takes a longer retention time of 90
days, it is less sensitive to
environment changes, stable, efficient
and could guarantee excellent
pollutant biodegradation efficiency of
above 95%.
Bioreactor System
This is a simple and innovative
bioreactor process that is capable of
treating POME efficiently. The system
is superior to the conventional system
as it operates with very short hydraulic
retention times, takes high organic
loading, requires less space and is
more environmentally friendly.
Composting System – USES SP8000 FOR COMPOSTING
The composting system offers an effective solution to the oil palm industry’s
perennial problem of waste disposal. The composting system utilizes 100% POME
and EFB and uses a technically advanced method and SP8000-COMPOST
ACCELERATOR to convert these waste matters into compost. EFB are firstly
shredded using a high speed hammer mill and then stacked into windrows of 1.5
meter high by 45 meter length in an open field. POME with BOD levels less than
10,000 ppm is then pumped from the pond and sprayed onto these windrows at a
specified rate at 3 days intervals. The windrows are turned regularly using a
windrow-turner for better mixing and aeration. SP8000-Compost Accelerator is
sprayed once at the start of the process to accelerate the composting process.
Throughout the composting process, the windrows are covered by an air-permeable
covering to avoid drenching by heavy rain and to prevent leaching of nutrients. The
covering is crucial for the control of temperature and moisture content, two key
factors that affect the speed of composting and quality of the end product. The
compost reaches maturity within 30 to 70 days before it is ready for use. The
compost, when used in sufficient quantity, is capable of replacing 66% of chemical
fertilizers.
