Opus DaytonKnight can be a valuable partner on your team for Biosolids Management Solutions.
To manage the
sludge that is generated from wastewater treatment units, Opus DaytonKnight incorporates digestion technologies like
(Autothermal Thermophilic Aerobic
Digestion) and Thermophilic Anaerobic Digestion.

Dewaterability of Thermophilically Digested
Dayton & Knight and the University of
British Columbia have been jointly sponsoring a research project that
investigates dewatering aspects of ATAD biosolids.
The research effort studies if operating
conditions such as feed sludge composition, digestion temperature, and
sludge retention time can be optimised for improved dewaterability of
thermophilically digested biosolids.
This project also searches for factors that
have the most significant impact on dewatering properties, and explores
mechanisms of solid-liquid separation in relation to dewatering.
Laboratory-scale, aerobic bioreactors of thermophilic and mesophilic
digestion were operated and various digestion temperatures were tested.
This study indicated that digestion
temperature, rather than duration, appeared to be a more important
factor affecting dewaterability. Current efforts are directed
towards identifying more effective means of improving dewaterability of
thermophilic biosolids. It is envisioned that valuable information will
be obtained from this research to assist in planning and operating more
cost-effective, thermophilic sludge digestion as part of secondary waste
