Scenario 2

WATER HYACINTH & AGRICULTURAL WASTE DISPOSAL

Water hyacinth invasion of Nile waterways has become a serious problem for transport, fisheries and irrigation in Egypt. Other Nile countries such as Sudan and Uganda are also experience problems caused by water hyacinths. This invasion of waterways is mainly due to the increased nitrification of the Nile caused by increased

populations along its banks and the banks of Lake Victoria inUganda and added nutrient run-off from agricultural waste. The use of Biogas technology can mitigate these problems. Harvesting and ensiling the water hyacinth before digesting it in the biogas system, will reduce water hyacinths in the river and irrigation channels. Adding other organic waste from agriculture and villages will ultimately reduce nitrogen run-off.

Energy produced can power irrigation pumps and provide electricity and hot water to local communities. Systems can be staged along the course of the Nile river. The systems can be interconnected to form a distributed energy network, providing redundancy during times of system maintenance and repair. The systems can vary in size in accordance with need. These systems can be configured to produce from 50kWe pr hour to 500kWe pr hour.
