This presentation delves into the settling of particles in water and its implications for human health. It explores the processes by which particles, including sediments, pollutants, and microorganisms, settle in aquatic environments. Key topics include the role of settling in water treatment, sedimentation rates, and factors influencing particle behavior. Discussions also address health risks associated with sediment-bound contaminants, such as heavy metals and pathogens, and their potential impacts on water quality and public health. By elucidating these linkages, the presentation aims to inform strategies for water management and treatment that minimize health risks and ensure safe drinking water for communities.
Wastewater pretreatment methods for constructed wetland: Reviewpetro karungamye
One of the most interesting research topics has been the constructed wetlands (CWs) for wastewater treatment. The primary operating issue of CWs is medium clogging, which
is caused by the accumulation of varying sorts of solids, resulting in a reduction in the infiltration capacity of the gravel substrate. It is commonly recognized that effective wastewater pretreatment is necessary for the long-term operation of CW. Pre-treatment is crucial because it prepares the influent for CW treatment. The primary treatment's goal is to reduce the solid load on the wetland, and the suspended solids concentration should not exceed 100 mg L1. This review paper describes the methods employed for wastewater pretreatment for constructed wetland performance. Three technologies namely septic tank, coagulation waste stabilization ponds and biofilters have been described
L11 -SECONDARY TREATMENT OF SEWAGE - TRICKLING FILTERS.pptxPRACHI DESSAI
Wastewater treatment is a process used to remove contaminants from wastewater and convert it into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation).

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.

4. Clarification
The removing of solid matter from a
liquid to make it clear is Called
Clarification
WEC University of Wah1/27/2016 4
5. Explanation
Removal is generally accomplished by
coagulation, flocculation, and
sedimentation. The combination of
these three processes is referred to as
conventional clarification
WEC University of Wah1/27/2016 5
6. Coagulation
It the process of destabilization by
charge neutralization. Once
neutralized, particles no longer repel
each other and can be brought
together.
WEC University of Wah1/27/2016 6
7. Flocculation
It is the process of bringing together
the destabilized, or "coagulated,"
particles to form a larger on.
WEC University of Wah1/27/2016 7
8. Sedimentation
It refers to the physical removal from
agglomeration suspension, or settling, that
occurs once the particles have been
coagulated and flocculated
WEC University of Wah1/27/2016 8
9. Agglomeration
It arises from interaction between
particles, as a result of which they
adhere to one another to form clusters.
WEC University of Wah1/27/2016 9
11. Types of Clarifiers
The design of most of the clarifiers falls into three
categories:
Horizontal flow Clarifier
Solids contact Clarifier
Inclined surface Clarifier
WEC University of Wah1/27/2016 11
12. All the three Clarifiers are shown
WEC University of Wah1/27/2016 12
13. Horizontal Flow Clarifiers
Originally, conventional clarification units
consisted of large, rectangular, concrete basins
divided into two or three sections.
Each stage of the clarification process occurred in
a single section of the basin. Water movement was
horizontal with plug flow through these systems.
WEC University of Wah1/27/2016 13
14. Continued
•Because the design is suited to large-capacity
basins, horizontal flow units are still used in some
large industrial plants and for clarifying municipal
water.
•The retention time is normally long (up to 4-6
hr), and is chiefly devoted to settling. Rapid mix is
typically designed for 3-5 min and slow mix for 15-
30 min.
WEC University of Wah1/27/2016 14
15. Cont,d
The long retention also allows sufficient reaction
time to make necessary adjustments in chemical
and polymer feed if raw water conditions suddenly
change.
However, for all but very large treated water
demands, horizontal units require high
construction costs and more land space per unit of
water capacity
WEC University of Wah1/27/2016 15
16. Inclined surface Clarifier
Hydro-Flo Technologies' line of Inclined Plate
Clarifiers is engineered to remove settleable
suspended solids from wastewater or process
streams by the most efficient means available.
A properly designed Inclined Plate Clarifier will
remove these solids, allowing downstream filters
or process equipment to perform as designed, as
well as reducing overall operating costs and
improving overall system maintainability.
WEC University of Wah1/27/2016 16
18. Every Hydro-Flo Inclined Plate Clarifier is available with
numerous plate spacing options.
By altering the plate spacing (to allow for different solids
loading ratios, settling rates, etc.), Hydro-Flo can make
certain your clarifier is sized appropriately for your
application.
WEC University of Wah1/27/2016 18
19. By combining the plate spacing options with
different Inclined Plate Clarifier configurations,
Hydro-Flo ends up with the largest line of clarifiers
available.
This allows us to solve a tremendous variety of
water treatment issues, making Hydro-Flo
Inclined Plate Clarifiers.
WEC University of Wah1/27/2016 19
21. Sludge Blanket and Solids-Contact
Clarification
Most upflow designs are called either "sludge
blanket" or "solids-contact" clarifiers.
After coagulation and/or flocculation in the
sludge blanket units, the incoming water passes
through the suspended layer of previously formed
floc.
Figure shows on upflowsludge blanket
clarifier(next slide).
WEC University of Wah1/27/2016 21
23. Reason
Because the center well in these units is often
shaped like an inverted cone, the rise rate of the
water decreases as it rises through the steadily
enlarging cross section.
When the rise rate decreases enough to equal the
settling rate of the suspended floc exactly, a
distinct sludge/liquid interface forms
WEC University of Wah1/27/2016 23
24. Explanation
Sludge blanket efficiency depends on the filtering action as
the freshly coagulated or flocculated water passes through
the suspended floc. Higher sludge levels increase the
filtration efficiency.
In practice, the top sludge interface is carried at the highest
safe level to prevent upsets that might result in large
amounts of floc carryover into the overflow.
Excessive sludge withdrawal or blow down should also be
avoided. The sludge blanket level is often highly sensitive
to changes in throughput, coagulant addition, and changes
in raw water chemistry and temperature
WEC University of Wah1/27/2016 24
27. TREATMENT OF HOSPITAL WASTEWATER
Name- Tabish.I.Malik
Enroll- 190/11
Roll no.- 52
Sec- AWEC University of Wah1/27/2016 27
28. Wastewater composition refers to the actual amounts
of physical, chemical and biological constituents
present in wastewater.
Hospital wastewater may contain various potential
hazardous materials including, microbiological
pathogens, radioactive isotopes, disinfectants, drugs,
chemical compounds and pharmaceuticals.
WEC University of Wah1/27/2016 28
29. The major aim of wastewater treatment is to remove as much
of the suspended solids as possible before the remaining water,
called effluent, is discharged back to the environment.
The selection of suitable treatment technology and proper
treatment of hospital wastewater is essential.
WEC University of Wah1/27/2016 29
30. WHY TREAT WASTEWATER?
As solid material decays, it uses up oxygen, which is needed by
the plants and animals living in the water.
Fisheries -Clean water is critical to plants and animals that live
in water.
Wildlife Habitats-Our rivers and ocean waters teem with life
that depends on shoreline, beaches and marshes.
Recreation and Quality of Life-Water is a great playground
for us all. The scenic and recreational values of our waters are
reasons many people choose to live where they do. Visitors are
drawn to water activities such as swimming, fishing, boating.
