Q: Assume a rough estimate of MSW composition is as follows: % by weight Moisture content (%) Paper (assume dry mass all cellulose, C6H10O5) 40 8% Glass 10 - Steel 10 - Aluminum 10 - Food waste (assume dry mass all sugar, C6H12O6) 30 80% a) If 20,000 metric tonnes of this waste is for anaerobic digestion, how much methane gas would theoretically be produced? b) If 20,000 metric tonnes of this waste is for aerobic composting. How much oxygen would theoretically be demanded?
Estimate the theoretical production of landfill gas (CH4 only) from the degradation of 20.3 kg of rapidly decomposable MSW. Assume the density of methane is 0.7177 kg/m3. Note:Hand written solution should not be used.
The landfill volume required for dry solid waste generated by a food factory per year is 300 m3. After drying the wet solid waste from the factory X% of it is recycled, followed by 2.5X% diversion for composting and 400 m3 for incineration, before the remainder is sent to the landfill. Using the information given below: Density of dry solid waste = 460 kg/m3 Daily generation of wet solid waste = 2200 kg Moisture content of the wet solid waste = 32% (ii) Determine X% and estimate the dimensions of the landfill site if the length: width : depth = 6:5:4
A Semi-solid waste storage has a volume of 1145 m3. The basin is initially 71% empty. The semi-solid density is 1521 kg/m3 is taken away from the storage tank at a rate of 5211.81 kg/day. How long will the basin take to be 91% emptied? Assume the storage is now initially full 23% and re-estimate the time to empty it
(a) In the town of Abesim, it is determined that the per capita waste generation rate is 1.4 kg (3.1 lb) per person per day. The collection is conducted once per week by the municipality. If the density of MSW in a typical trash container is 150 kg/m3, how many 120 L (30 gal) containers would be needed for a family of four? (b) From (a), collection trucks have a capacity of 11.5 m3 (15 yd3), which can compact the waste to a density of 420 kg/m3. How many customers can a truck handle in a single run, before departing for the transfer station?
01: A sample of industrial waste water have BOD: (1254 6mg/L) and biological oxidation (3.4 day) at 20°C, if the "k" value rise to (5.5 /day) calculate BODS, then calculate BODs at (28" and 44 C).Discuss your results according the BOD value and other conditions.
