BIOTECH
- WASTE TO ELECTRICITY PROJECT
(Module digester model )
(Module digester model )
In Chennai, The capital of Tamilnadu, India
BIOTECH has designed and
installed a compact and pre fabricated Bio waste to Electricity plant at Sri
Sankar Nagar, Pammal, Chennai, the Capital of Tamil Nadu, India
This plant is capable of
treating 300 Kg. of organic waste every day. Bio methanization technology is
applied for this process. The process involves the breaking down of the waste
substances into simpler substances for the consumption of microorganisms
resulting in the by production of methane and carbon dioxide. 25-30 Cum Biogas is being generated every
day. This gas is utilized for power generation. 40 KWH of electricity is
generated every day. It is used for meeting the in-house requirement for the
project and for street lighting. 50 N0s. of Compact Fluorescent Lamps (CFL)
have been installed nearby the streets and these are working with green
electricity.
The specialty of this plant
is that it is totally a pre-fabricated one, made of Fiber Glass Reinforced
Plastic (FRP). The system is equipped with three anaerobic pre-digesters and
three Modified Up-flow Anaerobic Sludge Bed (MUASB) reactors connected in
series. The treated liquid that comes out from the plant is utilized as
fertilizer and a part of this treated slurry is re used for the operation of
the plant with the help of an inbuilt slurry loop system. The slurry is of high
nutrient content and does not have any polluting properties like that of
chemical fertilizers. The Biogas
generated from the pre-digesters and digesters are passed through a non return
unit and collected in a centralized synthetic gas collector. This gas is passed
through a gas scrubber and after scrubbing it is used as fuel in a 100% Biogas
engine for the generation of electricity.
The main advantage of the
prefabricated system is the saving of space and time required
for the
installation. Without much expense all parts of the plant can be shifted from
one place to other if necessary. It is maintenance free and uses only minimum
moving parts. The treated solid manure can be removed from the pre-digester.
Through the introduction of pre-digesters, there is no chance for formation of
scum in the digesters. Predigesting also helps in better performance of the
reactor as the physical conditions can be maintained at required. The expected
life of the plant is more than15 years. The Environmental benefit derived
through the installation of the plant is equivalent to the emission reduction
of more than 100 metric tones of CO2 every year. It also solves the
problem of waste disposal and the other negative impacts like pollution,
diseases, unaesthetic appearance of the city etc related to it.
