hazardous waste landfill, waste treatment plant, deep-injection well, and incinerator?

Question

Can anyone tell me what these are and how they are done? Or know a good site that has all this info? Hazardous waste landfill, waste treatment plant, deep-injection well, and incinerator.

Answer 1

Not all deep injection wells are pumped full of just saltwater.

Back in the '60's and '70's there were several chemical plants in Denver that were producing chemical weapons, (nerve gas products), fertilizers, and pest control products.
Many of the waste products they produced ended up being injected into deep wells when they were cleaning the area up.
In the late '60's we started having small earthquakes in the area, which was supposed to be stable and seismic event free. They finally traced the cause of the earthquakes to the deep injection wells where they were pumping all of the waste products. The theory was that the wells were so deep, and the pumps so powerful that they were lubricating the underground rock surfaces and causing them to slide on one another and causing the earthquakes.
They susequently shut down the deep wells and pumping systems and we haven't had an earthquake since. That whole area was declared a superfund site, is now cleaned up and is a nature preserve.

A hazardous waste landfill is simly a regular landfill that has a liner or impervious layer of clay laid down first, to keep the landfill wastes from leaching into the soil and subsurface water tables. They are also bermed or protected to keep the products disposed of there from spreading or blowing around to other areas.The wastes that are dumped there are considered hazardous materials, and a record of all products dumped there are maintained for each site. There are several large ones located in the state of Utah. Hazardous radioactive products have their own separate disposal methods and sites.

A Waste Treatment Plant is usually a facility that treats a city's wastwater streams to remove all pathogens before releasing the cleaned up water back into the environment, such as back into a river.

Incinerators come in all shapes and sizes and types. There are incineration systems that take what would normally go to a regular landfill and burn it to produce power, there are others that are designed to burn only hazardous wastes, either in a regular furnace or in a rotary kiln. Some of these produce power, but most do not. All of them usually have scrubbers attached to clean up the gases produced by combustion by removing hazardous particulates.

Believe it or not the US government has determined that Tires and shingles and fiberglass and a few other things like asphalt are hazardous wastes..Now the definition of haz mat is a little broad because plutonium also falls into this catqgory too.
In A Haz mat landfill most of the products are thought to be benign. But due to the fact that a petroleum product was its base it is stored there. LIKE tires and road ashalt etc....

In a waste treatment plant the primary input is processed so that its chemical composition is most suitable for the lessening of the ecological or enviromental impact. Or in some cases so that other processes can take place in an easier manner.

In a deep injection well a solution of substances sometimes brine water are pumped to depths of 10k feet or more . These wells can actually serve a couple of purposes ...the first being getting rid of the salt water which came from there anyway and since water displaces nat gas and oil it forces the remnants of the neighboring wells contents to the surface.
Howerever most deep injection site are salt dome drilled and are only filled with non-potable brine water.

In an incincerator the substance is forced into a BOF(basic Oxygen furnace) and burned at high temp until the offending substance is no longer a threat. In the oil refinery a diatomacious earth filter is used to remove heavy metals like chrome and arsenic . When exhausted the filter is burned in an incinerator and the materials are rendered harmless..

Well i hope this helped a little...Good luck from the E...

Answer 3

I won't as long as the waste management service follows the standards set by EPA and the state.
