3. Introduction
• Water is the most common liquid on Earth. But, only
0.01% of total water accessible for consumption.
• Effective use of water becomes pivotal. In such
scenario wastewater treatment becomes very
significant.
• Wastewater treatment is the process that removes the
majority of the contaminants from wastewater or
sewage and produces a liquid effluent suitable for
disposal to the natural environment.
• As the waste water cannot be discharged in the natural
environment due to its hazardous nature, its treatment
employs certain physical chemical and biological
processes for producing an effluent stream of relative
purity.

4. Literature Review
• AWWA Research Foundation prepared series of reports with a
comprehensive literature review on nature and solutions of water
treatment plant waste disposal problems in 1969.
• Concurrently effort was made to determine the type and quantities of
waste produced, the characteristics of the wastes, and the existing
methods of waste disposal in Illinois.
Presence of water treatment plants in India :
•In India, only five metro cities have treatment capacity close to
100% of their sewage generation, these are Hyderabad, Vadodara,
Chennai, Ludhiana and Ahmedabad.
•Delhi has the largest sewage treatment capacity in absolute terms,
but it is only about 60% its needs, while Mumbai has the second
largest treatment capacity in absolute terms but meets only 80% of
its needs.
•Almost all other major metropolitan cities have treatment
capacities below 50% of their sewage generation.
•A 2010 report by the New Delhi based Center for Science and
Environment (CSE) put the effective treatment capacity at only 19%
of total sewage generation3 compared to an installed capacity of
30%.

5. Efforts to expand municipal sewage treatment
• Acknowledging that cities cannot tackle the sewage
problem alone, the central government launched the
Ganga Action Plan. Subsequently, Action Plans for
other rivers were also taken up and separate programs
were merged under the National River Conservation
Plan (NRCP).
Framework for wastewater reuse
• The only directly relevant policy for wastewater reuse
is the CPCB standards for land application of treated
wastewater for irrigation.
• While the general discharge standards for discharge
into surface waters cover 33 parameters, those for land
application for irrigation only cover 8.
• In addition, for each industry specific discharge
standard, there are standards for land application.

6. SCOPE OF THE PROJECT
• With UN reports warning of water stress being faced by the
two thirds of global population by 2025, the scope of waste
water treatment is a large one.
• Wastewater treatment plants are going to see being used in
different technical setups.
• Sewage treatment plants
• Tertiary treatment
• Agricultural wastewater treatment plants
• Leachate treatment plants
These waste water treatment plants can be installed in
numerous setups which may be industrial, institutional, in
human colonies as well as agricultural lands until there is
requirement for safe disposal of waste water generated.

12. Quantity Estimate

13. DESIGN
• Effluent Quantity:-
The generation of effluent has been considered from
toilets, pantry, rooms etc. and office as well, if any.
Design flow considered - 15 cum/day (maximum)
Raw Effluent Quality:-
Raw effluent characteristic is considered to have the
following characteristic:
pH - 7.5 – 8.5
BOD, mg/l - 250 - 300 (max)
COD, mg/l - 450 - 500 (max)
TSS, mg/l - 300 - 350 (max)
O&G, mg/l - 30 – 50 (max)

14. Treated Water Quality:-
The treated water characteristics as per P.C.B norms will be as follows:
pH - 6.5 – 7.5
BOD, mg/l - < 20
COD, mg/l - <150
TSS, mg/l - < 10
O&G, mg/l - < 10
We do not stand guarantee for any other parameters except the above as per the norms of
PCB.
C. Design Basis:
•High Rate Flexible Digester (HRFD) method has been considered for treatment of the
sanitary wastewater or in other words the treatment will follow the principle of Anaerobic
Sludge Blanket Process.
D. Treatment Methodology:
•The removal of BOD, TSS, Bad Odour and E-Coli will be done in proposed anaerobic tank
followed by filter by dosing of EM in a proper dosing pattern.
•The bacterial strains of EM will form a sludge blanket at the bottom of the tank within 20–25
days time after which the load on the tanks will come down substantially.
•The clear water then overflows from the top of the tank to the Treated Effluent Sump from
where it will be pumped through filters to the final discharge point.

15. E. Treatment Programme of EM:
For initial stabilization we recommend 10 liters followed by 4 liters
per month as preventive maintenance dose.
Progressive stages of developments after of EM.
F. Progressive Stages:
• Within 3 to 7 days of starting the EM programme, bad odor will
get reduced significantly.
• Commencing from the 2nd week onwards the BOD, TSS, E-Coli
values will reach an optimum level of treatment.
• By 4th week BOD, TSS etc. will start achieving the desired levels
of pollution parameters.

23. WORKING PROCEDURE
There are several waste water treatment technologies that are :
1. Wastewater Collection
2. Odor Control
3. Screening
4. Primary Treatment
5.Secondary Treatment
6.Bio Solids Handling
7.Disinfection
8.Sewage Treatment

25. CONCLUSION:-
I. The waste water have high BOD, Turbidity and total dissolved solids. Our
aim is to make this water safe for disposal in natural environment or to use
it for other purposes.
II. The DO content of waste water recorded is found to be low value due to the
presence of higher organic matter and an increased BOD and COD.
III. This increased BOD and COD value indicate the polluted nature of the
discharge. We’ve to treat it at least below to 20ppm.
IV. Higher quantity of inorganic nutrients like nitrogen & phosphorus was
found present in the waste water.
V. The waste water has a Ph range of 7.5-8.5
VI. Most Probable Number value was higher again indicating the polluted
nature of the waste water.
VII. Disposal without any treatment in to fresh water body may impose the
danger of eutrophication as well as serious problems of health and
hygiene.
VIII. Long term leaching of waste water may alter the soil characteristics as
well as may influence the quality of ground water.
IX. The treated wastewater can be utilized for purposes like gardening,
washing vehicles and cleaning garages, etc.
