a method for treating bioorganic or raw or treated wastewater sludge so that a stability based upon achieving a significant microbial population , conductivity level and percent solids , is developed rapidly , is provided for indefinitely and is independent of climatic conditions . a dewatered sludge that has not been treated or a sludge that has been treated to a psrp level or a sludge that has been treated to a pfrp level , i . e ., pasteurized or sterilized sludge when still in a wet condition , i . e ., between 12 %- 30 % solids , or when in a dry condition , i . e ., between 30 - 60 % solids , is mixed with alkaline adsorptive materials to reduce odor , to increase the percent solids and to facilitate granulation , is adjusted to a mildly alkaline ph , and is adjusted to an ionic conductivity which will allow the sludge to mature rapidly when seeded with a beneficiating microbial flora . this process will reduce the ph or a high alkaline treated sludge , e . g ., often above ph 12 , to a physiological ph of between 7 and 9 . 5 or will raise the ph of a treated acid sludge to a similar range so that microbial activity can proceed to facilitate stability . heat may be applied to the mixture to accelerate the carbonation and aid the overall drying process . the granular product , substantially due to its active microbial population , is useful as an agricultural product and topsoil blend .
