Transcript of ARTIFICIAL MARSHES


Artificial marshes are being planted to further cleanse the effluent(liquid waste or sewage discharged into a river or the sea) from sewage treatment plants or to make the water draining process from abandoned mines less acidic.
It can polish effluent from septic tanks of small buildings or clusters of a small building.
It can remove phosphorus from water during some periods, releasing it during other periods allowing it to act as a buffer (A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable).
It can improve water quality by removing toxins from water by absorbing the toxins.
It can also improve water quality by filtering out pollutants from drainage water, chemicals, sediment, and etc.
WHAT DOES IT DO
HOW IS THIS A IMPROVEMENT TO TRADITIONAL TECHNOLOGIES ?
HOW CAN IT IMPROVE WATER QUALITY ?
ARTIFICIAL MARSHES
HOW DOES IT WORK
WHICH POLLUTANTS CAN IT REDUCE ?
POSSIBLE IMPLEMENTATIONS.

Artificial marshes can reduce sewage water by purifying/filtering it.
they are more aesthetically pleasing then most conventional treatment facilities.
Using a plants nutrients to improve water quality.
Eradicating(destroying) harmful things that are in water.
It can also reduce organic waste that is accidentally or purposely combined with water.
Artificial marshes were created to treat anthropogenic discharge. It removes sediments and pollutants such as heavy metals from the water to make it soluble.
Artificial marshes consist of plastic-lined excavations(holes or pits) which contain vegetation that help improve the water quality.
Specially selected species are being planted on land that has been contaminated with one or more heavy metals. Some plants will accumulate the metals (which tend to be very toxic) in their tissue.
