Windrow composting of municipal biosolids in a cold climate
This work investigated the technical feasibility of composting digested municipal biosolids using outdoor windrows in an extremely cold climate. Common belief suggested this was not possible because of low ambient temperatures ...
Wastewater biosolids: an overview of processing, treatment, and management
Treated as a valuable resource, municipal sludge, often today referred to as biosolids, is processed through a variety of novel unit operations leading to a safe, aesthetically pleasing, and sought-after product. The design ...
Thermophilic anaerobic acid digestion of biosolids: hydrolysis, acidification, and optimization of retention time of acid digestion
The objective of the study was the optimization of the retention time in a thermophilic acid digestion system. To achieve this optimization, acidification index defined as the ratio between acidification rate and hydrolysis-rate ...
Inactivation of Ascaris suum eggs in digested and dewatered biosolids with lime and fly ash at bench scale and full scale
The feasibility of inactivating Ascaris suum eggs spiked into digested and dewatered biosolids from Winnipeg, Manitoba to class A levels (as per USEPA 1993) by storing the biosolids treated with lime (CaO) and (or) fly ash ...
Dewatering and coliform inactivation in biosolids using electrokinetic phenomenal
The feasibility of using electrokinetic processes for dewatering and fecal coliform (FC) inactivation Was evaluated on a bench scale. Six electrokinetic cells were filled with biosolids from an attached growth biological ...
