2. CONVERSION OF BIOMASS
FOR ENVIRONMENTAL
CHALLENGES
ENERGY CONVERSION

3. Bioenergy is energy of biological origin,
derived from biomass, such as fuelwood,
livestock manure, municipal waste,
energy crops
Coal
Tyres
Sugar Cane Bagasse
Oil sludge/waste
Energy crops
Oil seed rape husks
Rice and Corn husks
Packaging Waste
Chicken Waste
Wood chips /
waste
Straw
MSW
Nut shells
Sewage sludge
Olive pips
Bone meal
Leather waste
Animal litter

10. 1. Transfer of Food from Wastewater to Cell.
Adequate Mixing
Enough Detention Time
2. Conversion of Food to New Cells and Byproducts.
Acclimated Biomass
Useable Food Supply
Adequate D.O.
Proper Nutrient Balance
100 : 5 : 1
C : N : P
3. Flocculation and Solids Removal
Proper Mixing
Proper Growth Environment
Secondary Clarification
Filamentous Bacteria – Form Strings
Mixed Liquor Does Not Compact - Bulking
Biological Wastewater Treatment

11. The CRT for Best
Treatment
Will Vary for Different
Facilities
Determined by Regular
Monitoring and
Comparing to Effluent
Quality
Often Will Vary

12. Water needed to produce:
◦ 1 kilo of wheat: 1 000 litres
◦ 1 kilo of meat (beef): 15 000 litres
Daily water requirements per person:
◦ Drinking: 2-3 litres
◦ Domestic needs: 20–300 litres
◦ Food: 2 000-3 000 litres
with 2 500 litres of water, we can produce:
◦ food for one person for one day
◦ 1 litre of biofuel

19. CONCLUSION:
Biomass Utilization for Environmental
Challenges = Ecological solutions serves for
society
