Study the following statements and select the incorrect ones. (i) Physical removal of large and small particles through filtration and sedimentation is called primary sewage treatment. (ii) Secondary sewage treatment is mainly a mechanical process. (iii) Activated sludge sediment in a sewage treatment plant is a rich source of aeroic bacteria. (iv) Biogas, commonly called as gobar gas, is pure methane.

Given below are the steps involved in sewage treatment. Arrange them in proper sequence and select the correct option. A. Passage of primary effluent into large aeration tanks for mechanical agitation and pumping of air. B. Passage of secondary effluent and formation of activated sludge. C. Physical removal of particles through filtration and sedimentation D. Release of effluent from the secondary treatment plant into natural water bodies. E. Growth of useful aerobic microbes into flocs which significantly reduce the BOD.

Assertion : Secondary treatement of sewage is also called biological treatment while primary treatment is called physical treatment. Reason : Primary sewage treatment depends only upon sedimentation properties of materials present in sewage and filtration.
