A waste water plant produces 1000 kg of dry solids per day at a moisture content of 95 % . The solids are 70 % volatile with a specific gravity of 1.05 and the remaining are non-volatile with a specific gravity of 2.5. (After Digestion volatile solids reduces by 50 % & moisture content to 90%). Choose the correct options out of the following.
1
Volatile solids removed in digestion is 350 kg
2
Mass of water in digested sludge is 5850 kg
3
Sludge volume after digestion is 6.303 m3
4
Volume of water in digested sludge is 5.85 m3
