what is

a.Sludging

b.Septicemia

c.Crenation

Dear Student,

The semisolid material extracted after the treatment of industrial wastewater is called the sludge and the process of extracting sludg is called sludging. Septicemia is a commonly called the blood poisoning. It is the infection of blood caused by the bacteria or the toxins produced by them. Crenation is the contraction or the irregular folding of the cell membrane of animal cells when placed in hypertonic solution. This is due to the expelling of water from the cell into the medium.

Hope the definitions are clear to you.

Cheers!!!
