Dear Researcher N M .
You need to feel the waste water or water you wish to process.
The contaminants are in 3 phases ie one that floats, one that sinks to bottom and the others are particle in suspension..
there may be more floaters and less sinkers , then it is prudent to make the particles in suspension to float.. and they are easily skimmed at the 1st pre process stage itself.
Accordingly polymers are used.
As the polymers and contaminants are bio in nature, then the process is progressed.
The materials are bio in nature, hence the skimmed out matter is dried and bio- remedied.
Well wishes.
