Environmental Engineering

04/15/2015 10:24 AM

Good day, I enrolled for a long distance course for environmental Engineering, I work in an ice cream bussiness and know all the effluent treatment in our plant. I have never worked in the mines and I got this questions which is actually based in the mining industry, any suggestions?

You have been appointed as an Environmental Consultant for a Metallurgical company in Northwest Province. The site is situated in the middle of the town and is surrounded by residential and business areas. The company extract, produce and process Zinc, Nickel and Cadmium by the application of heat. The following substances or mixtures are emitted: Particulate matter (200 mg/m

3), Sulphur dioxide SO2 (600 mg/m3) and Oxides of nitrogen NOx expressed as NO2 (600 mg/m3).

Discuss in detail the procedure you will follow to ensure that the company complies with the requirements of the National Environmental Management: Air Quality Act, 39 of 2004. Also refer to relevant technology that can be used to ensure that the company complies with the Minimum Emission Standards in terms of Section 21 of the National Environmental Management: Air Quality Act, 39 of 2004.

I think the issue you're having is that you're knowledge base is water-centric but in Environmental Engineering and Compliance there are two other mediums in which you must also be equally familiar... Land and Air.

The above problem sounds Air-centric, so you'll need to ID the applicable emission limits - just like Water. But you will also need a base understanding of the process and the equipment utilized in the process - which is all obtainable through research.

At this point, I will help guide you in the right direction - you are not looking for Mining... try researching Smelting - both the process of, and the equipment used.

Find your limits in the permits for your location federal and local. Figure out if you are over. Apply the appropriate BMP. Leg work and calculations you'll have to work on.

Examp BMP for NOX and PM 10 is a SCR

SOx lime water scrubbers

Welcome to the forum.

You have been given the relevant documents: the National Environmental Management: Air Quality Act, 39 of 2004 and the Minimum Emission Standards in terms of Section 21 of the National Environmental Management: Air Quality Act, 39 of 2004. [40]

It is your job to do the legwork and research.

To be absolutely certain that the plant's emissions are compliant all the time then close the company. Worked in Bophal.

I am not sure of the detailed procedure for closing a company at your location.

How big is the legacy problem?

What country are these regs from? They're not US environmental regs. All air pollutants in the US are measured in ppm or tons per year.

Regrettably, it is one of CR4's rules that homework is not carried out here.

On the other hand, if the concern is a genuine installation, then an experienced Environmental Consultant should be hired at the earliest opportunity in pursuit of a solution to the problem. Caustic scrubbing would be one of the technologies worth considering.

Mining impacts the Environment, therefore the question is appropriate. Good Luck answering it.

OK now that I read the follow up post I see that it is a HOMEWORK question. Research it yourself you lazy gerbil. When I learned waste water treatment, I studied like a mad man to earn my certification. Read a book! Ask a colleague! Go to school! Oh wait. You're of th entitled generation so just go on the internet and buy your degree like most of the other lazy scumbags that think a piece of paper entitles them to a high paying job and all the perks. Good luck!?!?!?!?

At least he told everyone right off the bat is was homework.

Not my field at all, but looks like he just needed a nudge in the right direction.

Just my two cents. I'll show myself out now.

Re: Environmental Engineering

We normally don't do homework here, but since you are responsible for all the ice cream, I suppose an exception is in order.

If you totally remove all the particulates and vapors from the air around various points in the smelting operation (this is beyond the perview of the mine), make the wastewater as pristine as the driven snow (or better), and make sure nothing leaks into the local soil, or reaches the aquifer, then you have answered the question.

Now all you have to do is define "nothing", and "totally remove", and propose means to arrive at those. By the way, these definitions in the United States have changed over the years. They used to be in units of ppm, but now they are probably in ppt.

That means parts per million (ppm) in the olden days, but now that we all have iPods, we analyze all pollutants down to parts per trillion (ppt). If not, then at least ppb - you can surely figure out what ppb means.

Here is a link to the applicable legislation,(S Africa),2004

You must do your homework to get the answers.

If you are looking for ready-made answers,you are in the wrong place.

To paraphrase a former DI:

"If you are looking for Sympathy,you will find it in the dictionary

between Shiitake and Syphilis."

Good luck!(If you believe that luck has more value than hard work and preparation).
