Regarding sewage quality parameters with regard to physical and chemical characteristics, mark V for True or F for False: ( ) Turbidity is caused by the abundance of suspended solids in the water, the fresher and more concentrated the sewage, the greater its turbidity. ( ) Phenols present in sewage are inorganic compounds derived from domestic effluents, and despite being organic matter, they do not cause any change in water quality. ( ) Sewage, both fresh and old, derived from both domestic and industrial activities, is always gray or black in color. ( ) Household effluents have a BOD of around 300 mg/L, which means that 1 liter of sewage consumes about 300

( ) Sewage, both fresh and old, derived from both domestic and industrial activities, is always gray or black in color.
( ) Household effluents have a BOD of around 300 mg/L, which means that 1 liter of sewage consumes about 300 milligrams of oxygen in 7 days.
( ) Phosphorus is a component that can be present in sewage in both organic and inorganic form. In large quantities, the compound causes the exaggerated growth of algae in the medium, which can cause the death of local aquatic life, this phenomenon is called eutrophication.
