Environmental engineering is a branch of engineering that focuses on protecting the natural environment and improving the quality of life by addressing environmental problems and finding solutions to them. Environmental engineers work to design systems, processes, and technologies that minimize waste, reduce pollution, and conserve natural resources. They may also be involved in the development and implementation of environmental policies and regulations, as well as in the management of natural resources, such as water, air, and soil. Environmental engineering is a broad field that encompasses a range of topics, including air quality, water treatment, waste management, and sustainable development. It involves the application of scientific, engineering, and technological principles to the protection and restoration of the natural environment. If you are looking for the best web content writing services to help you communicate information about environmental engineering or other related topics, there are many companies and individuals who offer such services. They can help you craft clear, concise, and engaging content that will effectively convey your message to your target audience.

According to an article from Assignment Writing Services UK We've met numerous content area and elective teachers who are interested in learning more about environmental science (ES) out of a sense of love and concern for the environment. They also want to pass on their enthusiasm and expertise to their students while remaining true to their instructional focus.

For instance, an English language arts teacher may initiate a project in which students advocate for environmental issues in their community by writing letters to local politicians offering solutions. A social studies teacher can assist students in comprehending the legislative process by examining landmark environmental laws or by demonstrating how state and federal governments collaborate to address issues affecting ecosystems throughout the United States.

As a result, when we set out to write Environmental Science for Grades 6–12: A Project-Based Approach to Solving the Earth's Most Urgent Problems, we set out to create a resource that both ES and non-ES teachers could use to adapt projects that demonstrate the interdisciplinary nature of ES while also appealing to a diverse student population.

We recommend that teachers interested in trying their hand at ES have a firm grasp on the purpose of environmental education, which is to investigate environmental issues and work toward solutions while engaging students in projects in which they learn about conservation, create calls to action, collaborate with others, and resolve environmental issues in their communities.

When teachers are planning learning experiences for their students, we recommend that they choose a relevant ES theme and organize their students' learning using three helpful frameworks:

1. Next Generation Science Standards (NGSS): A nationally adopted framework for science education that includes content standards but also emphasizes scientific practices and crosscutting concepts that span all four science domains.

2. Academic Social and Emotional Learning Collaborative (CASEL) SEL Integrated Framework: By categorizing students' knowledge, skills, and attitudes into five domains, this framework for social and emotional learning enables students to gain a better understanding of themselves, their environment, and others.

3. Student Standards for the International Society for Technology in Education (ISTE): These standards help teachers design learning experiences that help students develop the skills necessary to thrive in a digital world.

Teachers can align with the three frameworks by carefully crafting learning objectives for ES projects organized around a theme that assists students in resolving critical environmental problems. How to do it in two easy steps.

1. CHOOSE AN APPROPRIATE PROJECT THEME

Projects involving ecosystems/ecology, or the study of the interactions between communities of organisms and their physical surroundings, and those that examine human impact on the environment and ways in which harms can be mitigated or prevented, are two good places to start.

Ecosystems: Two of ES's guiding principles are an understanding of the structure and function of ecosystems and the ability to communicate complex scientific concepts in simple terms. Addressing these fundamentals in an ecosystem and communication project can lay a solid foundation for more complex ES research in the future. One excellent way to combine these two concepts is to conduct research into why certain species are endangered, the factors that constrain or disrupt the ecosystem services that may be involved, and what can be done to inspire others to advocate for positive changes. ELA teachers can assist students in developing a compelling call to action that will help them understand the importance of communication in advocacy and engaging others.

Human consequences: The government's role in enforcing environmental laws relates to social studies. The visual arts are connected to scientific illustrations and the design of informative and visually appealing infographics. And the process of managing natural resources and balancing our own society's needs against those of other communities, both human and natural, generates opportunities in a variety of other academic disciplines.

Biodiversity is a concept that serves as a gateway to a variety of other subjects. Students can use mathematics to calculate the rate of depletion of Atlantic cod while honing their reading skills by analyzing excerpts from Mark Kurlansky's book Cod. Students from more urban areas may gain a greater sense of authenticity by analyzing publicly available data on the biodiversity of wildlife in their city parks and then creating infographics illustrating the predator-prey relationships that enable these populations to remain stable. They can use this knowledge to write persuasive pieces arguing for stronger action to protect fish populations or to create short-form infomercials using multimedia technology tools and fine arts skills.

2. APPLY TECHNOLOGY AND SELF-EFFICIENCY SKILLS

Ecosystems and human impact can be connected in a variety of ways to the aforementioned learning frameworks. Students have the opportunity to discover that environmental education does not have to be limited to science class. Here are some considerations for teachers when developing their learning objectives via learning targets.

With standards centered on human sustainability and natural resource management, NGSS is a natural fit for ES. In addition to the NGSS, teachers can utilize the ISTE Standards for Students to assist students in integrating appropriate edtech use across projects. It's also critical to understand that the ISTE standards are not simply about enhancing instruction with technology; they were purposefully written to align with academic subjects. And, given the pervasiveness of computers and apps in our daily lives, the standards benefit learners by preparing them to be global collaborators capable of leveraging technology to solve ES problems in novel ways.

There is an increasing body of research demonstrating the link between the causes and effects of nature experiences and how they can benefit children's learning and social and emotional well-being. The CASEL integrated framework's self-awareness competency is an excellent vehicle for assisting students in comprehending their emotional responses and thereby strengthening their emotional intelligence skills. ES projects can be beneficial in this regard as they navigate their emotional intelligence journey.

CAMUS‐SBT  is an  oxygenation  engine that outperforms  conventional  technologies

likeActivated Sludge Process (ASP), Sequential Batch  Reactor (SBR),  Membrane  Bio Reactor

(MBR)and Moving Bed Bio‐reactor (MBBR). Our technology harnesses a  special set  of

 bio‐chemical reactions  to deliver  the  oxygenation required for effluent treatment. 

In  conventional technologies,  aeration isachieved mechanically, which is very energy

intensive.  At higher ambient  temperatures (like inIndia) the solubility of oxygen in water

is  low, therefore  energy  requirements of mechanical  aeration  used by  conventional

technologyincreases.  Moreover, air contains only20% oxygen, the rest being nitrogen that

ispassed into water wastefully, further adding to process inefficiency.

CAMUS‐SBTresolves this problem  using a  bio‐chemical method  of  oxygenation, which

notonly uses the atmospheric oxygen, but also uses the  nitrogen  from the  atmosphere  in  a

specially  engineered natural  ecology  to achieve the desired level of purity.

In  addition conventional  technologiesgenerate  large  amount of  sludge  for which

additional  disposal facilities  have  to  becreated.  CAMUS‐SBT  does not  face  any such

problems.Theschematic of the process is shown below.  

Featuresof our technology:

• ·         Low‐energy consumption

• ·         All green natural process

• ·         No moving  parts  apart from pumps

• ·        No bio‐sludgeformation

• ·         Efficient removal  of  COD and nitrogen

• ·         Near drinking  water  quality after treatment

• ·        Treatment  cost Rs  3‐5  per 1000L

• ·        Garden likeambiance

• ·         Bio‐tower designs  available for spaceconstrained areas.

• ·        One time mediainstallation

• ·         Long life

• ·         Unskilled personnel  sufficient to operate

• ·        No foul Odor

Varioususes of the technology

·        Sewage treatment plant(STP)  and industrial effluent treatment plant (ETP)applications.

·        Retrofit ofpre-existing STP/ETPs with SBT/CAMUS-SBT systems. 

·        Laundry EffluentTreatment for total water reuse. 

·        Distilleryspent-wash treatment. 

·        Coffee Effluenttreatment.

·        Hospitals waste water ,Hotels waste water,Municipal waste water can all be treated using SBT.

·        Design of zerodischarge air scrubbers for removal of waste noxious gases (Sulphur, NOx  

              and organic pollutants from Industrialprocesses).

Currentlyaverage consumption of an individual per day is around 135 Liters per day (mayvary with climatic conditions) and it is increasing with the increasingstandards of living and to add to it our fresh water source are continuouslydepleting. Out of this 135 liters around 50% is being used for secondarypurposes like toilet flushing and bathing etc. which can easily be treated andrecycled which will save a lot of fresh water It’s high time now that we throwour water in the municipal sewer lines and depend on the government to takecare of it which is extremely difficult. The better approach can be to treatthe water locally at our housing complex or bungalows or your commercialcomplexes and reuse it for secondary purposes which doesn’t really requirefresh water sources .The recycled water can be used for gardening and flushingby providing a separate lines but people have a mental block for using therecycled water.

To Take aninitiative to recycle waste water in there facilities one has to do following

1.)   Assess the water consumption which can be doneby the total number of residents and multiplying by average water consumption.

2.)   Decide an area for the STP. Preferably itshould be an open area but not accessible to children

3.)   IF you wish to install SBT units the pleasemail us at vec@visionearthcare.com with theabove details .

4.)   It generally takes 2-3 months for a new SBTunit to be installed and get functional.

5.)   If you already have an STP working and if youwant to retrofit it then also please mail us and we will retrofit your existingplant using SBT

6.)   Typically SBT unit require 1-1.5 m2 per KLD(can be included under garden area and design is flexible)of sewage to treat withan operating cost of 3-4 Rs. Per KL

7.)   Various designs are available for spaceconstraint area and for hilly regions where laying of sewerage pipelines isdifficult.

"Scientists have developed the first mobile app to identify plants by simply photographing a leaf. The free iPhone and iPad app, called Leafsnap, instantly searches a growing library of leaf images amassed by the Smithsonian Institution. In seconds, it returns a likely species name, high-resolution photographs and information on the tree's flowers, fruit, seeds and bark. ...
Leafsnap debuted in May, covering all the trees in New York's Central Park and Washington's Rock Creek Park. It has been downloaded more than 150,000 times in the first month, and its creators expect it to continue to grow as it expands to Android phones.

Smithsonian research botanist John Kress, who created the app with engineers from Columbia University and the University of Maryland, said it was originally conceived in 2003 as a high-tech aid for scientists to discover new species in unknown habitats. The project evolved, though, with the emergence of smartphones to become a new way for citizens to contribute to research.
..Leafsnap cost about $2.5 million to develop, funded primarily by a grant from the National Science Foundation. It will cost another $1 million to expand it within the next 18 months to cover all the trees of the United States, involving about 800 species.

"Perfect for use as a festive decoration at Christmas time or use all year round to decorate trees, shrubs, parasols, and other outdoor items. Perfect for areas where electricity is unavailable or difficult to run wiring. That makes these solar string lights perfectly safe to use almost anywhere. The most important feature we wanted to ensure, was dusk to dawn illumination. Therefore we incorporated a powerful, but compact, solar panel and a high capacity battery all contained in a neat, weatherproof controller box, which has a removeable ground spike. In most applications these lights should run dusk to dawn after a full charge. In fact, after a full charge, during our tests, they were still functioning over 100 hours later without seeing any sunshine. These are probably the best solar string lights you will find so order your set now while stocks last! The 104 LED bulbs never need replacing. They automatically illuminate at dusk and switch off at dawn and come on an approximate 37’ cord. The controller allows several different modes, such as slow twinkle, fast twinkle, all on, slow sequence, fast sequence, reverse sequence etc. Available in three color choices, choose from a set of all white, or a set of white & blue, or a set of green, amber & red. Color of fixture is black."

 Solar Power from Satellites

At some point before 2050, satellites collecting solar power and beaming it back to Earth will become a primary energy source, streaming terawatts of electricity continuously from space. That’s if you believe a recent report from the Pentagon’s National Security Space Office, which says confidently that we will see “a basic proof-of-concept within 4-6 years and a substantial power demonstration as early as 2017-2020″.

It’s obvious in some ways: above the atmosphere, a solar cell receives about 40 times more energy per year than an equivalent site on the ground, due to the absence of atmospheric scattering and seasonal or nightly reductions in light.

The NSSO suggests that an orbiting spacecraft with solar panel arrays would be comparable to current ground-based installations spanning hectares and, eventually, a few square kilometres. Then that energy can be sent to the ground - using, the Pentagon suggests, a giant laser or microwave beam.

The report, Space Based Solar Power as an Opportunity for Strategic Security, suggests optimistically that one application will be the beaming of “energy aid” via satellite into conflict and disaster zones, minimising the human cost of resource wars and catastrophic events caused by global warming.

“The technology has been in development for a while,” says Joseph Rouge, associate director of the space office. “The truly hard and expensive part is going to be getting it into orbit. We’ll need regular launches and on-orbit robotic assembly systems. It’s a $10bn [£4.8bn] programme, but by 2050 it could deliver 10% of America’s power needs.”

Solar power could be the world’s number one electricity source by the end of the century, but until now its role has been negligible as producers wait for price parity with fossil fuels, industry leaders say.

Once the choice only of idealists who put the environment before economics, production of solar panels will double both next year and in 2009, according to U.S. investment bank Jefferies Group Inc, driven by government support especially in Germany and Japan. 

Similar support in Spain, Italy and Greece is now driving growth in southern Europe as governments turn to the sun as a weapon both against climate change and energy dependence.

Subsidies are needed because solar is still more expensive than conventional power sources like coal, but costs are dropping by around 5 percent a year and "grid parity," without subsidies, is already a reality in parts of California.
Very sunny countries could reach that breakeven in five years or so, and even cloudy Britain by 2020.

"At that point you can expect pretty much unbounded growth," General Electric Co’s Chief Engineer Jim Lyons told the Jefferies conference in London on Thursday, referring to price parity in sunny parts of the United States by around 2015.

"The solar industry will eventually be bigger than wind."
The United States’ second largest company, GE is a big manufacturer of wind turbines and wants to catch up in solar, said Lyons.
