Answer 1

13)Anaerobic sludge digestion is a biological wastewater treatment process that is used for the treatment and reduction of organic wastes such as organic sludge or concentrated organic industrial waste which contain solids.As the quantity of organic solids are decreased in the sludge after this process,the treated sludge is easier to dispose due to less volume.Further,microbial action during the process also helps in biogas generation(methane)which can be used as a clean energy source.


14)Water table:-
Water table is the upper surface of the zone of saturation.

Infilteration:-
Infilteration is the process by which precipitation or water soaks into subsurface soils and moves into rocks through cracks and pore space.
