Effectiveness of additives in sanitization of faecal sludge in emergency situations (Kenya)

My research tested the effect of promising chemical additives (Ikati and soda) and other additives in enhancing the reduction of volatile solids concentration and E. coli removal. This is especially important in emergencies when pit latrines fill up rapidly. Moreover, I also evaluated the effect of additives on odor, fly attraction and volume reduction as well as the application protocols of biological additives. My results showed that Ikati and soda are able to rapidly sanitize faecal sludge, and they are likely to achieve stabilization and volume reduction. In addition, I found no evidence to support the claim that biological additives can speed up the degradation rate of faecal sludge, thus extending the life of pit latrines.
