Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater that can be treated in sewage treatment plants. Most industrial processes, such as petroleum refineries, chemical and petrochemical plants have their own specialized facilities to treat their wastewaters so that the pollutant concentrations in the treated wastewater comply with the regulations regarding disposal of wastewaters into sewers or into rivers, lakes or oceans.
ntake structures are used for collecting water from the surface sources such as river, lake, and reservoir and conveying it further to the water treatment plant. These structures are masonry or concrete structures and provides relatively clean water, free from pollution, sand and objectionable floating material.
This presentation envisages on theory Of Filtration, Types of Filters, Slow Sand, Rapid Sand and Pressure Filters Including Construction, Operation, Cleaning, Operational Problems In Filters, Design criteria of Slow & Rapid Sand Filter Without Under Drainage System.

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).

Pollution from sewage is a primary environmental health hazard (wastewater effluent).
The purpose of municipal wastewater treatment is to limit pollution of the receiving watercourse.
The receiving watercourse may also be a source of drinking water.
All living things require clean, uncontaminated water as the most crucial compound for life on Earth
Ideally, drinking water should be clear, colorless, and well aerated, with no unpalatable taste or odor, and it should contain no suspended matter, harmful chemical substances, or pathogenic microorganisms.
Wastewater discharge from industries, agricultural pollution, municipal wastewater, and poor environmental sanitation are the main sources of water contamination

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
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.

Self Purification of Streams and DO
Sag Curve
Wastewater Treatments
Module-II
3
8. What is self purification of
stream?
• When wastewater is discharged into the river
or stream, the BOD of mix increases initially
and DO level starts falling.
• As river water travels further BOD gradually
reduces and DO increases and reaches its
saturation level.
• Thus river gets purified on its own.
• This phenomena is known as self purification
of stream 9
9. Disposal by dilution
• Disposal by dilution is a process in which the
treated wastewater from ETPs is discharged in a
large static body of water or in moving water bodies
such as rivers or streams.
• The discharged wastewater is purified in due course
of time, by the self purification process of natural
waters.
• The effluent discharge and degree of treatment of
wastewater depends upon the self purification
capacity of the river and its intended water use
10
10. Conditions favouring dilution without treatment
1. Where wastewater is quite fresh.
2. SS have been removed from wastewater
3. Volume of receiving water body is more than the
wastewater discharge
4. Dilution water having high DO, to satisfy the BOD
of wastewater
5. Where swift forward currents are available
6. Wastewater does not contain toxic substances
7. Water is not used for drinking immediately after
point of discharge.
11
11. Standards of dilution
Dilution factor Standards of purification required
Above 500 No treatment required. Raw sewage can be
directly discharged into river
Between 300 to 500 Primary treatment such as PST is required so
that SS concentration is less than 150 mg/lit
Between 150 to 300 Treatment such as screening, sedimentation
and chemical precipitation are required so
that SS concentration is less than 50 mg/lit
Less than 150 Thorough treatment is required SS should
be less than 50 mg/lit and BOD 5 should be
less than 20 mg/lit 12
13. 1. Dilution
• When sewage is discharged into a large
volume of water flowing in a natural stream or
river, it is dispersed and dilution takes place.
• Due to dilution the concentration of various
constituents such as organic matter, BOD,
suspend solids, etc., is reduced and thus the
potential nuisance of sewage is also reduced.
• Analogy for dilution is Making of Rasana or
juice from any squash

State whether you can find out pH of mix by using the formula that you have used to find
DO, BOD and Temperature of mix? If answer is no, Why?
18
20. • No. pH can not be determined by above
equation.
• pH varies logarithmically therefore pH of mix
can be found out by different formula.

Self Purification of Streams and DO
Sag Curve
Wastewater Treatments
Module-II
23
23. 2. Dispersion due to currents
• Self purification largely depends upon
currents, which readily disperses wastewater
in the stream, preventing locally high
concentration of pollutants.
• High velocity improves aeration which
reduces the concentration of pollutants.
• High velocity improves re-aeration which
reduces the time of recovery, though length of
stream affected by the wastewater is
increased. 24
24. 3. Sedimentation
• If stream velocity is lesser than the scour
velocity of particles then sedimentation will
take place, which has two effects
1. SS contribute largely to BOD will be removed
by settling and hence downstream water
quality will be improved.
2. Due to settled solids anaerobic
decomposition may take place
25
25. 4. Oxidation
• The organic matter present in the
wastewater is oxidized by aerobic bacteria
utilizing dissolved oxygen of the natural
waters.
• This process continues till complete oxidation
of organic matter takes place.
• The stream which can absorb more oxygen
through reaeration can purify heavily polluted
water in short time
26
26. 5. reduction
• Reduction occurs in the stream due to
hydrolysis (separation of water from
organic molecules) of organic matter
biologically or chemically.
• Anaerobic bacteria will split the organic
matter into liquids and gases, thus
paving the way for stabilization by
oxidation
27
27. 6. temperature
• At low temp activity of bacteria is
low., and hence decomposition is
slow., though DO will be more because
increased solubility of oxygen in water.
• At higher temperature purification will
take lesser time though amount of DO
is less in the water.
28
28. 7. Sunlight
• Sunlight helps certain micro-organisms to
absorb CO2 and give out oxygen, thus
resulting in self purification.
• Sunlight acts as disinfectant and stimulates
growth of algae which produces oxygen
during photosynthesis.
• Hence wherever there is algal growth water
contains more DO during daytime.
29
31. 1. Zone of degradation
• Situated just below outfall sewer
• Water is dark and turbid with sludge at the
bottom
• DO reduces up to 40% of saturation level
• CO2 content increases
• Rearation is slower than deoxygenation
• Conditions are unfavorable for aquatic life
• Anaerobic decomposition takes place in this
zone 32
32. 2. Zone of active decomposition
• Water in this zone becomes greyish and
darker than previous zone
• DO concentration falls to zero
• CH4, H2S, CO2 and N2 are present because of
anaerobic decomposition
• Fish life is absent but bacteria are present
• At the end of this zone DO rises to 40% of
saturation
• Aquatic life starts to reappear. 33
33. 3. Zone of recovery
• Process of recovery starts
• Stabilization of organic matter takes place in
this zone
• BOD falls and DO content increases above
40% value
• NO4, SO4 and CO3 are formed.
• Near the end of this zone entire aquatic life
reappears
34
34. 4. Clear water zone
• Water becomes clearer and attractive in
appearance
• DO rises to saturation level
• Oxygen balance is attained
• Recovery is complete
• Some pathogenic microorganisms may be
present
35
42. • When pollutional load is discharged into
the stream, DO goes on reducing. This
process is known as deoxygenation.
• It depends upon organic matter present
and temperature.
• The variation or depletion of DO is
represented graphically by deoxygenation
curve.
43
43. • At the same time oxygen gets added into the
stream through various processes such as
photosynthesis, rains etc.
• The curve representing oxygen gaining
process is known as Reoxygenation or
reaeration curve
• In a running polluted stream deoxygenation
and reaeration processes go hand in hand.
• Id deoxygenation is more deficit results.
44
44. • The amount of DO deficit can be obtained by
graphically adding both the curves. The resultant
curve is known as ‘DO sag curve’.
• DO deficit is given by
DO deeficit = saturation DO – Actual DO
= DO sat - DO act
• Streeter Phelps equation can be used for analysis of
DO sag curve
45
50. • Xc = Critical distance
= V x tc
V = Velocity of flow
