Bar Screen.
The equalization tank has suitable retention time to take care of peak flows. Coarse Bubble
Aeration Grid provided in Equalization Tank, to prevent the settling of solids. The homogenized sewage
is transferred at constant rate to the Aeration tank using submersible sewage pumps.
In Aeration tank, biomass media provided for maintaining the required volume of microbes. The
microbes (MLSS > 8000) attached on the media surface and move along with water. The Moving/
Fluidized state maintained by diffused aeration. The excess biomass growth on media shall get

hours and provided with air grid to maintain the required Dissolved Oxygen levels of 2 mg/lit. The
Settling tank has tube packs to provide the larger surface area for the effective solid liquid separation.
The over flow from the settling tank shall be collected in clarified effluent tank.
The Bio Sludge collected in the bottom of the settling tank is transferred through sludge pump
to the Filter Press and dewatered sludge is disposed to municipal wastes.
The clarified effluent is disinfected by dosing hypo and further polished by filtering through PSF
and ACF for removal of trace suspended impurities. The Filtration process helps to reuse the treated

2 EXISTING ENVIRONMENTAL SCENARIO
2.1. INTRODUCTION
Baseline study is conducted in order to identify any potential impact and changes to the natural and
socioeconomic environments and to have a thorough understanding of the nature of those existing
environments prior to commencement of the proposed activities. This translates as a need to
characterize the existing baseline environmental and socio-economic conditions including establishing
the prevailing conditions for a range of media through primary monitoring, undertaking focused surveys,
and the collection of secondary information from various published sources.
The baseline environmental quality data collected during the study period within a radius of 5.0
km of the project site for the study. The studies and data collection have been carried out systematically
and meticulously as per relevant IS codes, CPCB & MOEF guidelines and the data collected for these
parameters are given in this report. View of the project site is shown in below image.

2.2 EXISTING ENVIRONMENTAL QUALITY:
2.2.1 AMBIENT AIR QUALITY (AAQ):
To assess the ambient air quality status, monitoring stations were identified on the basis of
meteorology in the upwind and downwind direction as well as to represent the cross sectional scenario of
the project site. Based on the activities, the parameters chosen for assessment of air quality are Particulate
Matter <10(PM10), Particulate Matter <2.5(PM2.5), Sulphur dioxide (SO2), Oxides of Nitrogen (NOx) and
Carbon monoxide ( CO)
Calibrated Respirable Dust sampler (with an average flow of 1.2 - 1.4 m3/min.) were used for
monitoring of SPM, PM10 and a tapping provided in the hopper of the same sampler was utilised for
sampling of SO2, NOx, with proper flow controller.
PM10
Calibrated Respirable Dust Sampler with Whatman’s GF/A micro fibre filter paper was used for
the determination of PM10, is a measure of particulate matter having size <10microns.The dust
particles having size >10 microns is being collected in the cyclone and measured.
PM2.5
Calibrated APM 550 Fine Particle Sampler with Whatman’s standard PTFE 47 mm diameter
filter media was used for the determination of Fine Particles (PM2.5). PM2.5 is a measure of particulate
matter having size <2.5 microns. APM 550 Fine Particle Sampler is based on impactor designs
standardized by USEPA for ambient air quality monitoring.
SO2 (Modified West & Geake Spectrophotometer method)
Ambient air is bubbled at the rate of 1.0 l/min in an Impinger containing a scrubbing solution of
Sodium-Tetra Chloro Mercurate. The resultant complex is reacted with P-Rosaniline and Formaldehyde
to form coloured Para-Rosaniline methyl sulphuric acid. The absorbance of the solution is measured in
a Spectrophotometer at a wavelength of 560nm. The SO2 is then calculated from standard graph.
NO2 (Jacob & Hocheiser modified method)
Ambient air is bubbled at the rate of 1.0 l/min in an Impinger containing a solution of Sodium
Hydroxide and Sodium Arsenate. The resultant Nitrite Ion is reacted with Phosphoric acid,
CONCEPTUAL PLAN
47
Sulphanilamide and N-ethylene di-amine di-hydro chloride to form a coloured complex. The absorbance
is measured in a Spectrophotometer at a wavelength of 540 nm. The concentration of NO2 is then
calculated by using standard graph.
CO
The Carbon Monoxide samples were collected and analysed as per Non Dispersive Infra Red (
NDIR) spectroscopy
Three air sampling locations, one in the proposed project site and other two locations are in up
wind and down wind direction respectively.The details of the locations are given below
1. Proposed project site
2. Mother land sc hool,Telengupalayam ( downwind)
3. Vedapatti village ( upwind )
DATA ANALYSIS:
PM10 and PM2.5 values are ranging from 30 g/m3 to 52 g/m3 and 12 g/m3 to 22 g/m3
respectively. SO2 and NOx values are varying between 4.2 to 6.2 g/m3 and 6.2 to 14.2 g/m3
respectively. The CO values are found to be BDL ( > 114.5g/m3 ) at all locations. All the values are
found to be well within the NAAQ Standards 2009 prescribed by CPCB. The analysis report is given
in Annexure – 13.
2.2.2 WATER ENVIRONMENT:
Water samples were collected and analyzed as per procedures outlined in IS-2488/ IS-3025 /
AWWA / APHA. Sterilized bottles were used for collection of water sample for bacteriological analysis,
stored in icebox and transported to the laboratory for the analysis. Parameters like pH, Temperature,
Dissolved Oxygen, Residual Chlorine, Conductivity, Free Ammonia, Total Hardness, Calcium Hardness
and Magnesium Hardness were analyzed in the field while collecting the samples. MPN index of
Coliforms are determined in the laboratory as per standard methods.
The analyses were carried out as per the BIS & APHA standard methods
To assess the water quality, five locations are identified and samples were collected and analyzed
for physico-chemical,heavy metal parameters and bacterial examination. Four ground water and one

2.2.3 NOISE ENVIRONMENT
Ambient noise level measurements in four co-ordinal directions were carried out using CYGNET
sound level meter, with windscreen during daytime as well as night time. Noise measurements were made
at 1.5 m above ground and about 3m away from walls, buildings or other sound reflecting sources. The
readings were taken from morning 6.0 AM to 10 PM at 4 hours a regular interval which gives day time
Noise level. The average Leq values during Day time are reported. Similarly Night time noise level were
taken from 10 PM to 6 AM at four hours interval. Ambient noise levels are compared with CPCB
Norms.
To know the background ambient noise level 5 locations were identified for baseline study.
Mean Leq noise levels at day time and night time are ranging from 47.8 –54.2 dB(A) and 36.5 –
42.1 dB(A) respectively. While comparing with IS: 4954 -1986 norms for acceptable outdoor noise
