WASTE water treatment project........ Wastewater treatment is a process used to convert dirty wastewater into an effluent that can be returned to the water cycle with minimum impact on the environment, or directly reused. The latter is called water reclamation because treated wastewater can then be used for other purposes. The treatment process takes place in a wastewater treatment plant (WWTP), often referred to as a Water Resource Recovery Facility (WRRF) or a sewage treatment plant. Pollutants in municipal wastewater (households and small industries) are removed or broken down.
The treatment of wastewater is part of the overarching field of sanitation. Sanitation also includes the management of human waste and solid waste as well as stormwater (drainage) management.[1] By-products from wastewater treatment plants, such as screenings, grit and sewage sludge may also be treated in a wastewater treatment plant.[2]:Ch.14

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

4. A building in which are located and operated the
pumps of an irrigation system.
Pump houses are facilities including pumps and
equipment for pumping fluids from one place to
another.
They are used for a variety of infrastructure
systems.
5. Two types of pumping station exist:
Dry Pumping Station:
Built as a room outside of the water or watertight in
which the pumps are installed functioning in open air.
6. Flooded or Wet Pumping Station:
Built as a reservoir , in which submersible or vertical
pumps are installed.
7. The design of a pumping station should take into
account the following parameters:
Type of pumps chosen
Maximum water flow required to supply the
hatchery at any time
Preferred schedule of utilization of the pumps.
Different water flows required during the annual
production cycle.
Hydraulic conditions under which the pumps
operate.
8. Distributing water in the hatchery
Draining water from the hatchery
Air supply
9. Air supply means
distribution of air. The
process of air supply in
hatchery is an essential. A
vigorous supply of air in
all tanks of larvae,
Artemia culture, mixing
storage to keep to keep
dissolved oxygen level
high.
10. In the larval tanks air needs to be well distributed,
because its not only keep the oxygen level in the
whole tank but also keep the larvae a close contract
to their food.so that they can easily get food.
Some hatcheries air is distributed through several
rigid of 0.5-10imch(1.25-2. 5cm)diameter PVC pipe
with holes buy cut into them at 0.3-0.5m intervals
with a 1/32drills.
11. Others use weighted flexible
plastic tubing laid on the
bottom of the tank, with hole
punctured in them, but its
has some problems like the
holes in pipes and flexible
tubing become blocked,
besides pipes or tubing on
the tank bottom hide
detritus which provided a
favorable condition for the
growth of fungi and
protozoa and making
difficult to clean the tank.
However the use of good
quality stone is preferable
for this.
12.
13. Power house means an organization that produces a
lot of ideas or activity , and has a lot of power or
influence in its field.
In another word , it is a person who is very strong
and has a lot of energy.
In fact , power house is an electrical generating
station or plant.
14. The most essential equipment to generate electricity
is the ‘Turbine’ . There is a turbine which has the
power of rotation and through this rotation power or
electricity is produced which is then provided to our
locality.
15. Conventional Sources
• Thermal power
• Hydro power
• Nuclear power
Non –conventional Sources
• Wind power
• Solar power
• Biomass power
• Tidal wave energy
• Geo thermal energy.
19. Uses of Electricity in Hatchery
Electricity is essential to provide the necessary power to run
equipment.
For running the pump
For water supply and water treatment
For starting algal cultures etc.
So, installation of a stand by generator is absolutely
necessary especially in area where there are frequent
and/or lengthy power failures and fluctuation.
20. Ensure that a certified electrical supplier checks and
approves the system.
Check the power supply backup system regularly.
Provide automatically fused control boxes for each
item of equipment.
Select hatchery equipment with energy saving
features.
Ensures that the system has sufficient capacity for
future expansion.
22. “Degassing”
Degassing is the removal of organic gases from the
stationary tanks, containers or pipelines. Or, A degasser
is a device used in drilling to remove gasses from drilling
fluid which could otherwise form bubbles.
Degasser
For a small amount of entrained gas in a drilling fluid, the
degasser can play a major role of removing small bubbles
that a liquid film has enveloped and break out the air and
gas such as methane, H2s and CO2 from the mud to the
surface, the drilling fluid must pas degassing technique
and it can be accomplished by the equipment called
degasser which is also a major part of a mud systems.
23. Atmospheric Degasser
This type of degasser processes mud by accelerating fluid through a
submerged pump impeller and impinging the fluid on a stationary
baffles to maximize surface and thus enable escaping gas vent
atmosphere.
Atmospheric Degasser
24. Vacuum Tank Degasser
Vacuum type is the most common form
of degasser. It can be horizontal, vertical
or round vessel. A vacuum action is
created to pull in the gas cut mud. When
the liquid enters the tank it will flow and
be distributed to a layer of internal
baffle plates designed for the mud to
flow in thin laminar film and is exposed
to a vacuum that forces the gas to
escape and break out of the mud. The
vacuum pump moves the escaping gas
from the vessel discharging it to the
rig’s flare environmental control system.
Vacuum Tank Degasser
26. Effluent Treatment Plant
ETP is one type of waste water treatment method which
is particularly designed to purify industrial waste water for its
reuse and it’s aim is to release safe water to environment from
the harmful effect.
• Industrial effluents contain various materials, depending on
the industry.
• Some effluents contain oils and grease, and some contain
toxic.
• The ETP Plant works at various levels and involves various
physical, chemical, biological and membrane processes to
treat waste water from different industrial sectors like
chemicals, drugs, pharmaceutical, refineries, dairy, ready mix
plants & textile etc.
27. Effluent Treatment Process
The treatment of different effluents varies with the
type of effluent. Wastewater enters the effluent or sewage
treatment plant and goes through several processes before
effluent goes into the Hatchery. Effluent treatment plant
process include the following stages:
• Primary Treatment
• Biological Treatment
• Advanced/Disinfection Treatment
28. Primary Treatment
Screening:
• This is the first unit operation
• Its purpose is to remove large floating solids.
Sedimentation:
• It is a physical water treatment process.
• Using gravitational force to remove suspended solids from water.
Grit Chamber:
• The wastewater moves into the grit chamber and removes the
dense inorganic solids such as gravel, metal fragments and sand.
• Removal of grit can prevent damaging of pumps & operational
difficulties.
Neutralization:
• The main purpose of this process helps in maintaining the pH
range of 6-9 to meet the requirements of different processing
units in ETP system.
29. Biological Treatment
Using Bio-filter, it release the high quality water into the
next step of treatment. It helps to
• Remove bacteria and microbes
• Remove ammonia
• Remove nitrites
• Remove dissolved organic solids
• Add oxygen
• Remove carbon dioxide
• Remove excess nitrogen and other dissolved gasses
• Remove suspended solids
30. Advanced/Disinfection Treatment
UV Disinfection:
• It is considered as an ideal disinfectant.
• It leaves no residual disinfectant in the water by ensuring the
water quality.
• It does not produce any disinfection by-products.
Benefits of ETP:
• To clean industry effluent and recycle it for further use
• To preserve natural environment against pollution.
• To meet the standards for emission of pollutants set by the
Government & avoid heavy penalty.
• Reduce cost for marine fish hatchery by reuse of water.
