Re: Excreta disinfection

Dear Elisabeth,

The book, nevertheless, is interesting. I like the publication. The lead author is Daniele Lantagne of Tufts University, a great name in the field of WASH.

Re: Excreta disinfection

Dear Mughal,

This book chapter (in open access format) - which is linked to from the GWPP newsletter - might answer some of your questions, I think:
www.waterpathogens.org/book/emergency-response

It gives some examples for disinfection in emergency responses for the diseases of Ebola and Cholera. E.g. it says:

two novel in situ treatment/disinfectant systems were developed. The first system used coagulation/flocculation and disinfection with hydrated (slaked) lime, the second system the addition of hydrochloric acid, followed by pH neutralization and coagulation/ flocculation of suspended solids using aluminum sulfate (Sozzi et al., 2015). Both use pH changes (the first to high pH, the second to low) with the intent to inactivate the cholera bacteria.


I am not sure if this answers your questions?

Excreta disinfection

Excreta disinfection

A recent post of Global Water Pathogen Project, available at: mailchi.mp/abb1fc3b6c9d/april-11-2018-gw...sletter?e=10a5fc3af3
recommends disinfection of excreta in emergencies.

The concept is well-taken, especially since this deals with emergency. However, in certain areas, even the drinking water is not disinfected. In the rural areas of Sindh, Pakistan, the drinking water quality is simply pathetic – most unfit for drinking. Drinking water is pumped to the ponds, where settlement of coarse particle takes place – and that is the only treatment it gets. No disinfection whatsoever.

I’m wondering how, under such scenarios, the excreta disinfection can be accomplished?
