This presentation talks about biological treatment of leachate & domestic wastewater. Treatment process involves upflow anaerobic sludge blanket reactor. Efficiency achieved was around 90% by using different proportions.

2.  Overview.
 What is Biological treatment.
 Analysis of parameters.
 How we did it differently.
 Treatment workflow.
 Results & Discussion.
 Conclusion.

3.  Sanitary sewerage systems
serve only a low percentage
of the population.
 In non sewer areas, more
than 80% of the night soil is
treated in septic tanks.
 Therefore, using the
biological leachate treatment
plants to treat both MSW
leachate and domestic waste
water has been hashed out in
this study.

4.  It involves analysis of
physico chemical
properties.
 Examination of operating
parameters.
 monitoring parameters.
 experimental setup for
bioreduction of leachate.

5.  pH, COD, HRT, Temperature,
co-substrate was determined
for the samples.
 pH meter, ELICO makes
model LI 120, were used to
determine the pH of the
samples.
 COD is a measure of the
oxygen equivalent of organic
matter .
 HRT is defined as, the
volume of the reactor to the
volumetric flowrate.

6.  Solid wastes were collected freshly from omagulam
dumping site by vehicles and dumped.
 Leachates were collected from the land fill in which
the solid wastes collected and dumped.
 The seed sludge for reactors were collected from
high rate anaerobic digester, which was treating
distillery effluent located at M/s Sakthi Sugars Ltd.
Appakoodal, Bhavani, Erode Dt. and M/s Sriram
Narayana Sago Factory, namagripet, Rasipuram Tk,
Namakkal Dt.

7.  VSS was found out by using a known volume of the sludge was
filtered through what-man filter paper no. 44.
 Volatile fatty Acid has been found by taking a sample of 100ml and
tirated against 0.1N NaOH, after adjusting the pH on 6.5.
 For TSS a known volume of the effluent was filtered through a
Whatman filter paper no. 44 and carried in a pre weighed silica
crucible and evaporated to dryness by a heating device and then the
crucible was again weighted.
 Bio gas production was measured by water displacement method.
 The production of “5-day BOD test” as given in AOHA, 1992 was
adopted for estimating BOD5 for characterizing the effluent.

8.  UASBR reactor was used in
this work was drawn up of
vertical polyacrylic rectangular
shape tanks with internal
working volume of 15L.
 The elevation of the reactor is
3m in this working height was
2.4m with the width and
breadth of 0.18m and 0.061m
respectively.
 The inlet of the reactor was at
the bottom and the outlet was
at the top.
 This reactor contains four
sampling ports for every 60cm

10.  The waste water from septic tank was integrated
with the MSW leachate to feed the UASBR as
substrate.
Characteristics of the leachate

20.  The analysis report of domestic wastewater and
MSW leachate revealed that both the
characteristics were almost very similar.
 In time, efficiency the start up period of the
reactor was minimized up to 45days by seeding
the reactor with starch based sludge.
 The experimental results also demonstrate that
the COD removal by variable HRT is almost up
to 90%, whereas other parameters also
decreased drastically.
