Answer:
1)Wastewater is treated in 3 phases: primary (solid removal), secondary (bacterial decomposition), and tertiary (extra filtration).
2) Cogulation:-
coagulation is a process that changes circulating substances within the blood into an insoluble gel.
3) Substance:-
substance is matter which has a specific composition and specific properties. Every pure element is a substance.
4) Softening:-
The process of removing the dissolved minerals that is removable of calcium and magnesium salts which causes hardness in water.
5. Chlorine bleach.
6. Chlorine dissolves in water to form hypochlorous acid (HOCl) that partially breaks down again to form the hypochlorite ion (OCl-). Hypochlorous acid and the hypochlorite ion are toxic to potentially harmful microorganisms and disinfect drinking water.
Hope it helps.
