"Dehydration by adding dry organic material and long-term storage at high ambient temperature is the simplest treatment in order to transform faeces into a product that is safe for reuse or disposal. Dehydration can take place either on-site in a dehydration vaults or be done off-site in dehydration beds or bags protected from humidity.  Dehydration vaults are used to collect, store and dry (dehydrate) faeces  on-site (e.g. in double-vault [8225-UDDTs]) . Faeces will only dehydrate when the vaults are well ventilated, watertight to prevent external moisture from entering, and when urine and anal cleansing water are diverted away from the vaults.  Simple storage at ambient conditions (temperature, pH and moisture) can require several years for pathogens to die-off. Increase of temperature, pH (alkaline treatment) and minimisation of the moisture content can significantly accelerate the process. Clever design and ventilation will increase temperature and decrease moisture content, thereby enhancing the drying process. The addition of lime and ash will raise pH while sawdust will absorb humidity."
