By which process floating debris and grit are removed in STPs respectively ?
In Sewage Treatment Plants (STPs), floating debris is removed by filtration, and grit (like sand and small stones) is removed by sedimentation. Filtration helps in removing large particles, while sedimentation allows heavier particles to settle at the bottom.

which of these nitrogen fixing bacteria does not live in symbiotic association with host plant?
Azotobacter is a free-living nitrogen-fixing bacterium that does not form symbiotic associations with plants. In contrast, Rhizobium and Frankia form symbiotic relationships with leguminous plants and actinorhizal plants, respectively. Xanthomonas is not known for nitrogen fixation.
Which is correct sequence for purification process of STPs?
The correct sequence for the purification process of Sewage Treatment Plants (STPs) is: Primary Sludge -----> Effluent -----> Flocks -----> Active Sludge -----> Biogas. This sequence involves the initial removal of primary sludge, followed by the treatment of effluent, formation of flocks, conversion to active sludge, and finally biogas production.
