Waste water treatment?

Question

Can any one tell me about waster water treatment systems?

Answer 1

I haven't done this since college, but heres the basics:

They collect the wastewater through a collection of sewer pipes (using lift stations when gravity will no longer take the waste in the right direction) where it goes to a plant.  First they mechanically filter out any big particles and "grit" then they chemically filter out any more particles (using a chemical which bonds the particles together so they fall out as the water is passed along a set length) this material is sent to a landfill type place.  Then it goes to an aerator to promote oxygen for the aerobic bacteria phase and then an aneorobic digester where it is introduced to bacteria which turn amonia to nitrogen gas and ummm something c**p I'd have to look that up.  I don't recall which the aeorobic does and which the aneorobic does. Then it is sand filtered and returned to a body of water.  

I don't know if your sugesting this at all - but the talk about California recycling their residential waste to water is genious.  First off a sewer plant smells nothing like an outhouse...oh no...its a gazillion times worse.  There is industrial waste, chicken plant waste, you name it in there.  Then that water goes to the river, and goes to the lake we get our drinking water from anyhow.  Knowing what I know I would drink recycled toilet water happily over the way it's done know. I mean you do anyhow.

Answer 2

To care our environment we should keep our water clean.

Water treatment systems remove physical, chemical and biological contaminants from wastewater.

Answer 3

Generally speaking, domestic wastewater treatment systems all speed up a natural decomposition process by the mechanical addition of oxygen (air) to sewage which promotes breakdown of organic pollutants by organisms already present therein.

Answer 4

In home it is called septic system

.. .. ..

In the city it is called sewer system

.. .. ..

They both work on the biological break down of the wast material of mankinds body

... .. ..

And to some point the break down of the molecular  structural of in-organic waste material

.. .. .

In to a form that is reusable by animal and plants in nature to return it to the earth once again to become something new to be used by the plants and or animals of the planet earth
