Do all biosolids have an odor?
Untreated biosolids have an odor. Different treatment processes deal with odors differently, but often odors persist. The odors are subjective and each individual person has their own opinion. The N-Viro process deals with odors on many levels. First, the high surface area of the mineral by-products immediately absorbs odor. By further drying the product odors are not generated. The remaining micro flora prevent odors by inhibiting putrefying organisms from inoculating the end product. During the treatment process mild amounts of gaseous ammonia is released from the biosolids, and is one of the five modes of disinfection. It is this temporary, mild ammonia smell that is associated with the N-Viro process.
