0.112 kg in suspension
0.112 kg in solution
0.225 kg in solution
Both A and C of above
Answer is Right!
Answer is Wrong!
The correct answer is D. Both A and C of above.
Sewage is a mixture of water and solid waste. The solid waste can be suspended in the water or dissolved in the water. The suspended solids are the particles that can be seen floating in the water. The dissolved solids are the particles that are too small to be seen.
The amount of suspended solids in sewage is typically about 0.112% of the total weight of the sewage. The amount of dissolved solids in sewage is typically about 0.225% of the total weight of the sewage.
Therefore, 1000 kg of sewage will contain about 0.112 kg of suspended solids and about 0.225 kg of dissolved solids.
