  • The provision of sanitation services by fecal sludge management services has been accelerated in recent years. One common constraint in the sanitation value chain is malodor nuisance associated with fecal sludge. Adsorption of malodor onto biochar was hypothesized as one possible technology intervention to malodor nuisance. Adsorption studies were conducted using three biochars from pine, bamboo, and fecal feedstocks and an activated carbon as adsorbents, and a reconstitution of fecal malodors as the adsorbate. Batch and flow-through adsorption tests were performed. Odor was quantified using ascending concentration series method of dynamic threshold olfactometry by an odor panel, and a hydrogen sulfide (H2S) meter. Breakthrough capacities of the adsorbents for both odor reduction and H2S reduction were determined. Overall, the results provide baseline engineering data to apply and size biochar filters for adsorption as a malodor control method in various latrine settings.
