This document summarizes the key processes involved in wastewater treatment, including primary, secondary, and tertiary treatment stages. Primary treatment involves physical processes like screening and sedimentation to remove solids. Secondary treatment uses biological processes like trickling filters, activated sludge tanks, and anaerobic digesters to break down organic matter. Tertiary treatment provides disinfection using chlorination, UV light, or ozonation to remove pathogens before wastewater is discharged.
this presentation is about the reuse of treated wastewater.Different application and technologies involved. I have also put four case studies taken from some journals mentioned.
Deals with what is activated sludge, mechanisms and kinetics of treatment, design of activated sludge process, secondary clarifiers and their design and bulking sludge, raising sludge and foaming of ASP.

First presentation of my whole life, That's i want to share with you people. I think this presentation (SECONDARY WASTEWATER TREATMENT) may fulfill your requirement.
Actually when my teacher told me about our assignment I was felling nervous because I've never done this type of thing. when she asked one of my classmate to upload his PPT in class common email-ID, then I felt very bad !!!! not on their success but because I COULDN'T. At that time i promised to myself and with the co-ordination of my group member MR. AYUSH GOVIL, MISS. VERSHA DABAS, MISS KRITI SINGHAL and myself RISHAW KUMAR (TIWARI). And finally i got not only me, we winzzzzz.
thanx to,
Dr. TANNU ALLEN (our prof.)
and special thanx to my group member and my classmate. and you guys also.

I was asked to provide current markups of the electrical drawing set. The problem was that much of the equipment had been upgraded with no drawing supplied by the contractor. There was also no drawing standards at the time, so I quick created a new numbering system and block templates.

Industrial waste water is a type of waste water produced by industrial activity, such as that of factories, mills and mines.
It is characterised by its large volume, high temperature, high concentration of biodegradable organic matter and suspended solids, high alkanity or acidity and by variations of flow.
The treatment of wastes by micro-organisms is called biological waste treatment.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

3. Wastewater
used water or liquid that contains impurities or pollutants in the
form of solids, liquids or gases or their combinations.
generated by human due to various activities (daily activities,
commercial activities, industrial activities).
The final discharge of wastewater will normally onto the land
(receiving bodies of water may be ponds, lakes, streams, rivers, seas,
etc.).
It is harmful and will affect people health if wastewater being
disposed into the environment without any treatment processes.
4. Wastewaters can be classified as:
Domestic wastewater
- municipal/sanitary wastewater, simply sewage.
- used water which has been discharged from the
residential, commercial and industrial area of a city,
and collected through sewage system.
- generally it contains 99.9% water and only 0.1% of
organic and inorganic solids and also
microorganism(bacteria).
Industrial wastewater
- generated by large & medium scale industries.
- manufacturing industries produce a large volume of high
strength wastewaters.
5. Wastewater - What's In It?
Pathogens: disease-causing
organisms
Solids: suspended particles
that make the water turbid
Nutrients: such as
phosphorus that can cause
nuisance plant growth
Organic matter: that can
rob the oxygen resources of
streams
Toxics: metals and
synthetic organic chemicals
harmful to humans and
wildlife Wastewater Treatment Plants 5

7. Primary treatment
Removal of large solids from the waste water via
physical settling or filtration.
Screening
-- first step and involves the removal of large non-biodegradable and
floating solids
--- Such as plastic, branches, rags, metals , tins ,
containers , wood, bones
--Prevent the clogging and interference in further processes
--three types of screens– fine , medium , coarse screens are used.
SEDIMENTATIONSCREENING
8. A comminutor, also known as the grinding pump,
houses a rotating cutting screen. This cutting screen
shreds any large chunks of organic matter in the
wastewater into smaller pieces. This makes it easier for
the microorganisms to use the organic matter as food
.
A grit chamber allows pieces of rock, metal, bone,
and even egg shells, which are denser than
organic materials, to settle out of the waste stream.
Removal of grit prevents damage to machinery
through abrasion or clogging.
comminutor and grit chamber.
GRIT REMOVAL
Grit –includes sand , gravel, pebbles , cinder,and eggshell , bone chips ,
seeds, coffee grounds , and large organic particles in food waste
9. Sedimentation
physical settling of matter, due to its density,
buoyancy, and the force of gravity.
--Through sedimentation, the larger solids are
removed in order to facilitate the efficiency of the
further procedures and also to reduce the biological
oxygen demand of the water.

11. SECONDARY TREATMENT
• The second stage of wastewater treatment.
• Usually biological treatment is used to treat wastewater
in this step.
• It involves the removal of biodegradable dissolved and
colloidal organic matter using aerobic biological
treatment processes.
• This step mainly includes:
Trickling filters
Activated sludge tanks
Lagoons
Anaerobic digesters
12. TRICKLING FILTERS
• A trickling filter consists of a bed of highly permeable
media on whose surface microorganisms are
developed as a slime layer.
• Wastewater is applied intermittently, or sometimes
continuously, over the media.
• Organic matter in the wastewater diffuses into the
film, where it is metabolized.
• Aerobic conditions are maintained by splashing,
diffusion, and either by forced air flowing through the
bed or natural convection of air if the filter medium is
porous.
• This reduces the BOD by 70%.
14. ACTIVATED SLUDGE TANKS
•Activated sludge process is a
common method of aerobic
wastewater treatment.
•Uses air and a biological floc
composed of bacteria and protozoa.
•These tanks are large aeration tanks in
which air is mixed to wastewater.
•The tanks soon develop a highly
16. ANAEROBIC DIGESTERS
• Anaerobic digesters digest organic waste
in a machine that limits access to oxygen,
encouraging the generation of methane
and carbon dioxide by microbes in the
waste.
• This digester gas is then burned as fuel to
make electricity.
• Digesters aren't widely used yet, but tend to
be used for sewage sludge at sewage
treatment plants and for animal waste on
