Plant/Process Description:
Indorama Petrochems has recently commissioned a
660,000 TPA capacity PTA manufacturing Plant at
Thailand. This plant generates various waste
water streams which are high in organic contents
which is reflected by its high BOD, COD, TSS etc.
The flow rate is 275 M3/Hr with design COD values
of 37 Tons per day. The COD concentrations are
around 7000 ppm while BOD is around 3500 ppm.
The PTA waste water has very difficult to biodegrade
constituents which show lag phase during
biological treatment. The overall consultants for
this PTA plant were Foster Wheeler from UK. The
PTA manufacturing technology is sourced from Du
Pont, UK. After conducting very exhaustive search
by Indorama and Foster Wheeler through out the
world on the successful technology for PTA waste
water treatment it was observer that a properly
designed Anaerobic followed by Aerobic Treatment
System can treat the waste water upto the levels
suitable discharge.
The designers and turnkey contractors for WWTP
Systems throught theworld were contacted and the
tenders were floated to them. After receiving the
bids the technical scrutiny was done by involving
a team of technical people from Indorama, Foster
Wheeler and Du Pont. Various bids were evaluated
and only three bidders were short listed based on
their past experience and detailed discussions
were held with each of these bidders.
Finally UEM India Limited having their office at
D-19, Kalkaji, New Delhi-110019 India were
selected as the successful bidders. The person
dealing from UEM was Mr.naresh Verma - VP
Marketing (Cell : 91-9811144282, EMail :
nverma@uemgroup.com).
It was found after all the bids analysis that UEM
had the maximum experience of handling PTA waste
Water and had sucessfully executed PTA waste
water treatment plants at Reliance PTA facilities
in India (3 plants), Du Pont Far Eastern -
Taiwan's PTA facility, Indian Oil Corporation's
PTA facility at Panipat-India etc. All these
plants were working on a unique technology and
were producing very satisfactory results for the
last several years.
The technology proposed by UEM for Indorama's
plant was similar to their other installations.
This technology incorporated various treatment
steps such as Equilisation, Neutralisation,
Buffering, Primary Treatment, Temperature
correction, Anaerobic igestion in Twin Hybrid
Digesters (Twin AHR), Aerobic Treatment in
Sequential Batch Reactors (SBR), Polishing,
Sludge Thickening, Sludge Dewatering in Belt
Press etc.
Hybrid Technology for Anaerobic Treatment is a
unique combination of UASB - Up Flow Anaerobic
Sludge Blanket and UFF - Up Flow Fixed Film and
combines the benefits of both these technologies
and eliminates the individual technology short
comings. It does not depend on Granular Sludge as
is the case with UASB and does not allow any
sludge wash outs. The media - cross fluted PVC is
placed above the UASB zone where additional
biomass growth takes place offering very large
bio mass inventory resulting in satble and better
treatment efficiencies. The media zone also
arrests any sludge wash outs and send back the
sludge in the UASB zone below. In addition there
is also higher biogas generation as UFF zone has
significantly higher population os methogenic
bacterias.
The Two Digesters are planned to operate in
parallel as well as series mode. The PTA waste
water has certain constituents which show lag
phase in treatment and the series operation mode
is very effactive to degrade these constituents.
The AHR System can reduce the COD by about 70 -
75 % and for treating the remaining COD and to
bring it down to the desired discharge levels a
SBR System in three basins configuration is
provided. Three basin designs offers the plant to
accept the inflow continuously. The SBR - Aerobic
Biological Treatment System uses Fine Bubble
Diffusers in removable patter and works very well
for such wastes. It has three floating decanters
to discharge the treated waste water which is
finally discharged trough a polishing pond after
monitoring all desired parameters.
The excess sludges are thickened and dewatered in
Belt Filter Press before discharge out side the
factory.
