Application for ceramic filter and reverse osmosis membrane for produced wate...sunilkumarvss395
Ceramic filters and reverse osmosis membranes are both commonly used in the treatment of produced water in oil and gas operations.
1. **Ceramic Filters:**
- **Application:** Ceramic filters are often used as a pre-treatment step for produced water. They can remove suspended solids, oil, and some organic compounds. Ceramic filters are particularly effective in handling high temperatures and harsh chemicals commonly found in produced water.
- **Benefits:** They offer high chemical and thermal resistance, low operating costs, and can operate in harsh conditions without degradation. They are also relatively easy to maintain and have a long lifespan.
2. **Reverse Osmosis (RO) Membranes:**
- **Application:** RO membranes are typically employed for further treatment of produced water after pre-treatment with ceramic filters. They are effective in removing dissolved solids, salts, and other contaminants, producing high-quality water suitable for reuse or discharge.
- **Benefits:** RO membranes offer high removal efficiencies for dissolved solids, are capable of producing high-quality water, and are relatively compact compared to other treatment methods. However, they require careful monitoring and maintenance to prevent fouling and scaling.
**Combined Application:**
- Using ceramic filters as a pre-treatment step can help protect RO membranes by removing larger particles and reducing fouling potential, thereby extending the lifespan and efficiency of the RO system.
- Together, ceramic filters and RO membranes can effectively treat produced water to meet regulatory standards for discharge or reuse, contributing to environmental sustainability and operational efficiency in oil and gas operations.

Design of Waste Water Treatment Plant for treating the Effluent generated fro...Rita EL Khoury
One of the major issues of environmental pollution is the direct discharge of contaminated water into sewage system. In fact, operating the autoclave reactor unit in a medical waste treatment facility generates waste water that might cause environmental hazards if it doesn’t undergo an appropriate treatment process. The effluents generated from the autoclave drainage and from waste bins washing, being exposed to infectious medical waste, contain pollutants such as bleaches, particulates, detergents, and pathogenic microorganisms.
Medical waste must be decontaminated and treated without generating a secondary pollution. For this reason, a treatment process consisting of the following unit operations: aerated septic tank, sand filter, softener, cartridge and UV Sterilizer is designed in order to treat these effluents and thus re-use the obtained clean water for bins washing, as cooling water or if possible as boiler feed water.
Nowadays Air pollution is a major problem. Diesel engines are playing a vital role in Road and sea transport, Agriculture, mining and many other industries. Considering the available fuel resources and the present technological development, Diesel fuel is evidently indispensable. In general, the consumption of fuel is an index for finding out the economic strength of any country. In spite, we cannot ignore the harmful effects of the large mass of the burnt gases, which erodes the purity of our environment every day. The main pollutants contribute by automobiles are (CO), UBHC, (Nox) and Lead etc., Other sources such as electric power generating stations, industrial and domestic fuel consumption, refuse burning , industrial processing. So it is imperative that serious attempts should be made to conserve earth’s environment from degradation. An aqua silencer is an attempt in this direction, it is mainly dealing with control of emission and noise. An aqua silence is fitted to the exhaust pipe of engine.
The aqua silencer system is design for replace commonly used single unit silencers in engine with it’s slender structure and less weight. It plays an important role in control the noise and emission of gases from engines. Air pollution causes dangerous physical effect on the human body, animal and environment. The main reason to use aqua silencer is because nowadays air pollution is increasing rapidly. This system reduces the dangerous exhaust gases from the auto.
These emissions are controlled by the activated charcoal layer around perforated tube and lime water. The charcoal layer having high capacity to absorb emission gases from engine. This type charcoal layer with lime water reacts chemically with emission gases and change the chemical structure of emission gases. The smoke or emission gases and noise level in aqua silencer is very less than the commonly used silencers.
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

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. NEED OF ETP
Water is basic necessity of life used for many purposes
one of which is industrial use.
Industries generally take water from rivers or lakes but
they have to pay heavy taxes for that.
So its necessary for them to recycle that to reduce cost
and also conserve it.
Considering these criteria an Effluent Treatment Plant is
also being established in Rourkela Steel Plant.
Main function of this ETP is to clean GCP effluent and
recycle it for further use.
3. DESIGN PARAMETERS
Slurry Feed Characteristics
Type of Slurry Gas Cleaning Plant of Blast Furnace.
Flow Rate 1140 m3/hr
Suspended Matter 6000 ppm(Av of 4000-8000)
pH 4.5 – 6.5
Temperature 60-70oC. Analysis of suspended solids
a.) Fe2O3……………….71.42%
b.) SiO2…………………5%
c.)Al2O3………………..0 .4%
d.) CaO………………… 6%
Approx. particle size distribution e.) MgO………………….3.2%
f.) P………………………0.016%
< 10 micron: 30%
g.) S………………………0.483%
10 to 40 micron: 35%
40 to 60 micron: 15%
>60 micron: 20%
5. INLET LAUNDER
The purpose of launder is to flow the effluent of
gas scrubber to distribution chamber
Inlet channel is designed for a surge flow of
1950m3/hr @ slope of 2% so water flows at
1.5m/s(self cleaning velocity).
Self cleaning velocity is that velocity at which if
the sludge flows it will not get accumulated in
the launder.
6. DISTRIBUTION CHAMBER
Purpose of distribution chamber is to divide the
flow (design flow of 1140m3/hr) into two equal
flows.
In case if one of the thickener is closed then there
would be no distribution so selection of pipes is
done on this criteria.
The size of gates is designed such that there is
equal distribution always.
7. FLASH MIXER
There are two flash mixers designed for a flow of
1140m3/hr with a retention time of 60 sec.
So its volume must lie around 19m3 .
In flash mixer alum (coagulant) acts upon sludge
so that suspended solids settle down. In addition
pH of sludge is also raised by lime as it is
required to have a pH of 7-9. Polyelctrolytes
(flocculants) also act upon to fasten the process of
coagulation.
8. CHEMICAL ACTION OF ALUM AND LIME
Al2 (SO4)3.12H 2 O 2Al3+ + 3SO42- + 12H2O
SO42-+H2O HSO4-+ OH-
(Cause pH change)
Ca (OH) 2 Ca2+ + 2OH-
(Cause pH change)
The basic water causes Al(OH) 3 to precipitate
bringing small particles with them and then
making water clear. Fe2O3 is removed mainly by
coagulation.
The polyelectrolytes make big lumps of the
coagulated particles so they settle down.
9. CLARIFIER
The clarifier separates the treated slurry from
clean water.
The sludge settles down and clean water at the
top flows down to the cooling tower from where it
is cooled and recycled. According to PG the SS
content in this water must not be greater than
100 ppm.
The clarifier has a racker arm which extracts the
sludge out of clarifier. In case if sludge height
goes higher than the racker arm then it will
automatically lift up and then settle down taking
sludge with it.
From here sludge is pumped to sludge tank.
11. Sludge tank
In the sludge tank the sludge is continuously
agitated in order to prevent settlement of sludge.
Each tank has capacity of 224m3 and can hold for
8 hrs.
Main purpose of the tank is to hold sludge for
transfer to filter press.
From sludge tank the sludge is pumped to filter
press by filter press feed pump.
12. Filter press
Sludge from the sludge tank will be pumped to the Filter
Press equipments for dewatering purpose. According to
performance guarantee the cake moisture should not be
more than 20%.
For this purpose different types of filters are used namely-
gravity setters, gravity belt filters, centrifuges, vacuum or
pressure belt filters and filter press. But among these filter
press is most efficient and economical.
Other filtration systems offer high pressure filtration, but
only the filter press has both high pressure capability
and efficient filter cake removal. The filter elements
are constructed of lightweight polypropylene. They are
extremely corrosion resistant and virtually eliminate plate
breakage.
14. WORKING
Dewatering is accomplished by pumping a slurry
or sludge into chambers (A) surrounded by filter
membranes (B).
As pumping pressure is increased the filtrate is
forced through the accumulated filter cake (C)
and membrane until the chamber is full of solid
filter cake. The chambers are formed by two
recessed plates held together under hydraulic
pressure.
The hydraulic ram (D) moves the follower (E)
against the stack of filter plates (F) closing the
press. The ram continues to apply sealing
pressure of sufficient force to counteract the high
internal compaction pressures.
15. The head stock (G) and tail stock (H) are held in
place by specially engineered side rail support bars
(I). The filtrate passes through the membrane and
is directed by channels in the plates and drain ports
(J) to the head stock for discharge.
The filtrate typically contains less than 15 PPM
suspended solids. The filter cake is easily removed
by simply reversing the hydraulic ram, thus
opening the press. The lightweight plates may then
be moved apart, permitting the compacted cake to
fall from the chambers.
Higher the internal pressure, the greater the solids
compaction. The standard press is constructed to
withstand 100 PSI compaction pressure producing
a hard dry cake. The special high pressure press
can withstand 225 PSI for sludge more difficult to
dewater.
