Effect of Anaerobic Digestion on Manure Characteristics for Phosphorus Precipitation from Swine Waste

Swine production facilities today are larger in size and are concentrated in smaller geographical areas than they were two decades ago. Additionally, there is an increasing trend to base manure land application rates on crop phosphorus requirements rather than crop nitrogen requirements alone. These factors have resulted in a need to find a feasible method for removing phosphorus from swine was...

Anaerobic digestion of dairy manure with enhanced ammonia removal.

Poor ammonia-nitrogen removal in methanogenic anaerobic reactors digesting animal manure has been reported as an important disadvantage of anaerobic digestion (AD) in several studies. Development of anaerobic processes that are capable of producing reduced ammonia-nitrogen levels in their effluent is one of the areas where further research must be pursued if AD technology is to be made more eff...

Evaluation of pre-treatment efficiency of fats, oils and greases using low frequency ultrasonic waves to accelerate the process of anaerobic digestion

Background and Objective: Hydrolysis of fat, oil and grease by ultrasonic waves is a pre-treatment method before anaerobic digestion which can change their physical, chemical and biological properties. The main purpose of this study was to investigate the efficiency of ultrasonic waves to improve the hydrolysis process and its use as an auxiliary substrate to increase the efficiency of anaerobi...

Opportunities for Nutrient Recovery in Handling of Animal Residuals

Treatment methods are presented that can be used for nutrient recovery from animal manure and these processes are compared to the current practice. Using swine feeding operations as an example, the current practice for waste handling is that 97% of all produced waste is applied to owned or rented land after storing the waste in below-floor slurry pits or anaerobic lagoons without cover. This cu...

Significance of Vivianite Precipitation on the Mobility of Iron in Anaerobically Digested Sludge

Anaerobic digestion requires a balanced availability of micro-nutrients with ideal growth conditions to reach optimal organic degradation and biogas production. Iron is the most abundant of the essential metals in an anaerobic digester and its mobility has a strong impact on microorganisms through its own bioavailability, but also through its influence on the bioavailability of other metals. Mo...
