NUISANCE of digested sludge and reduces the vectors such as rodents, flies etc. attraction towards sludge.∴ Statement I is true and Statement II is falseOther points about gas production in anaerobic sludge digester:1. Out of TOTAL volatile solids, 65 % are induced to gasses and 35 % formed in digested sludge.2. The total volume of gasses formed during DIGESTION is either 0.6 m3/kg of Volatile solids or 0.9 m3 /kg of volatile solids reduce to gasses.3. Out of the total gasses formed 70 % is methane (CH4) and 30 % is Carbon Dioxide (CO2).
