Drinking water treatment technologies ppt.
Reverse osmosis and nanofiltration ro and nf.
The most widely applied water treatment technology a combination of some or all of coagulation flocculation and sedimentation plus filtration has been used routinely for water treatment since the early part of the twentieth century.
Technologies for potable water and other uses are well developed and generalized designs are available from which treatment processes can be selected for pilot testing on the specific source water.
In addition a number of private companies provide patented technological solutions for the treatment of specific contaminants.
This course will focus on understanding how these technologies work and when to apply them.
Water purifiers range from simple water filters to advanced purifiers using membrane technology for water filtration followed by disinfection with uv lamp filters.
Biological treatment of drinking water uses indigenous bacteria to remove contaminants.
However the process can certainly be scaled up to large scale applications since it is currently applied at large scale wastewater treatment plants for final effluent disinfection.
It is useful for removal of contaminants including nitrate and perchlorate.
There are many different types of water purifiers available in market.
