Demonstration of Dairy Manure Remediation Using Ibr Technology
نویسندگان
چکیده
This paper is a report of the performance of a new design of anaerobic bioreactor called the induced-blanket reactor or IBR. The IBR appears to treat high-solids organic matter (manure) effectively in a relatively short time without plugging. A 28 m (7500 gal), heated IBR has been in operation at the Caine Dairy, Utah State University’s dairy farm, since summer 2000. The bioreactor, an upflow-sludge blanket type, features a method to build and maintain a sludge blanket without plugging. Up to 80% of VSS were removed from dairy manure in the IBR, with less than 10-day HRT. Biogas was collected and burned to produce hot water. Parameters for the system that will be reported include pH, temperature, influent and effluent total and soluble COD, total and volatile solids and suspended solids, TKN, and NH3 all at different loading rates. Biogas quantity and percent methane will also by reported.

Dairy manure resource recovery utilizing two-stage anaerobic digestion - Implications of solids fractionation.
Dairy manure management is increasingly becoming an environmental challenge. In this regard, manure anaerobic digestion (AD) can be applied to address environmental concerns; however, dairy manure AD remains economically uncompetitive. Ongoing research is focused on enhanced resource recovery from manure, including maximizing AD methane yield through a novel multi-stage AD configuration. Resear...
متن کاملAn enzymatic hydrolysis approach for characterizing labile phosphorus forms in dairy manure under mild assay conditions.
Characterizing labile P forms in animal manure is a challenge due to their susceptibility to hydrolysis. In this study, we enzymatically characterized P forms in dairy manure (no bedding), collected from a representative dairy farm in New York, by separating into soluble and residual components under mild assay conditions using water and sodium acetate buffer (pH 5.0). About 75% of total manure...
متن کاملManure and microbes: public and animal health problem?
Most environmental concerns about waste management either have focused on the effects of nutrients, especially N and P, on water quality or have emphasized odor problems and air quality. Microbes from manure are often low on the priority list for control and remediation, despite the fact that several outbreaks of gastroenteritis have been traced to livestock operations. The pathogens discussed ...

The aim of this study was to determine the effectiveness of natural flocculants to reduce solids and nutrient loads in dairy cow wastewater using solid-liquid separation; chitosan was used as a model. Its use efficiency and optimum application rate were determined using flushed dairy cow manure of varied strengths - 0.4%, 0.8%, 1.6%, and 3.2% total solids (TS) content. Treatments consisted of n...
متن کاملRecycling of manure nutrients: use of algal biomass from dairy manure treatment as a slow release fertilizer.
An alternative to land spreading of manure is to grow crops of algae on the N and P present in the manure and convert manure N and P into algal biomass. The objective of this study was to evaluate the fertilizer value of dried algal biomass that had been grown using anaerobically digested dairy manure. Results from a flask study using two soils amended with algal biomass showed that 3% of total...
