New Technologies for Accessing the Power in Waste …continued
By Karleen Kos, PSAI Executive Director
THE SENEGAL INITIATIVE — Senegal is a nation that exemplifies many of the underlying issues that make up the global
sanitation crisis. A large p ortion of the population does not have access to improved toilets. Infrastructure for treating waste is
limited, as are water and power. Some of these challenges are inherent in the climate; some are complicated by political wind s
and property rights.
For several years, the Bill and Melinda Gates Foundation has been facilitating relationships b etween public and private
organizations in Senegal to create the political readiness to bring about and support the levels of sanitation that are requi red to
dramatically reduce the number pathogen - induced illnesses. This preparation made Dakar the top pic k for the first installation
of a Janicki Omni Processor – a new technology that had been developed in Washington State. Check out this 2 minute video
to hear Bill Gates himself explaining more about the background and how it works. You'll also see Bill dr ink water that was
fecal sludge only 5 minutes earlier. Here's a snapshot of how the system works, which is explained more fully in the video.
OPERATIONS — The core of the unit has an approximate footprint of 24 m x 13 m (312 m^2). The water purification unit
takes up an additional area of 12 m x 2.5 m (30 m^2). In its first year in Dakar, the J OP processed an estimated 700 tons of
fecal sludge while it was being tested. Operational capacity for the system is up to 7 metric tons of dried sludge per day, w hich
is harvested from drying beds located on the grounds of the facility.
• It now generates net electrical power of 125kW, annually producing 1000 MWhs of power.
• The system produces 11 cubic meters of hot, pathogen - free, potable water per day
