ONAS support for field testing of Janicki Omni-Processor

2015 - 2018 • ONAS National Sanitation Office of Senegal


Field testing in Dakar, Senegal, for the Omni-Processor as an innovative fecal sludge processing and recovery technology.


Since arriving in Dakar, the OP has processed an estimated 700 tons of fecal sludge. When operated at capacity, it can now process fecal waste at a rate of approximately 4,000 tons per year which means it can treat the waste of 50,000-100,000 people from the adjacent community. We have also successfully generated clean drinking water onsite.

Because of the entrenched perceptions from previous technology solutions in the sanitation industry, our solution at first glance is sometimes reviewed with skepticism that it can actually generate excess electricity. However, our pilot has successfully proven that this can in fact done operating in a self-powered mode, and on top of that, it can assist in supplying the power needed to run the aeration tank at the co-located WWTP – and that it can be done in both developed and developing world contexts.
