Swine wastewater treatment using attached-growth and suspended-growth two stage sequencing batch reactors with real-time control
Two two-stage sequencing batch reactors (TSSBR), one attached-growth and one suspended-growth, were operated under three levels of wastewater concentration (approx. 4,000, 2,000 and 500 TOC mg/L),...
Phosphorus transformations in swine manure during continuous and intermittent aeration processes
The objective of the study presented here was to determine the transformation of phosphorus (P) between different forms in the process of intermittent and continuous aeration. According to this...
Geotextile fabric-straw manure storage covers for odor, hydrogen sulfide, and ammonia control
Manure storages are a major odour source. Straw and/or geotextile fabric covers can be used to reduce these odour emissions. Thirty-eight 160-litre (42-gal) open-topped PVC pipes (columns) containing...
Effects of alum and aluminum chloride on phosphorus runoff from swine manure
Phosphorus (P) runoff from fields fertilized with swine (Sus scrofa domesticus) manure may contribute to eutrophication. The objective of this study was to evaluate the effect of aluminum sulfate...
Odor measurements for manure spreading using a subsurface deposition applicator
Odour emissions during manure spreading events have become a source of concern, particularly where farms are located nearby urban areas. The objective of the present study was to compare odour...
Raising pH by low-level aeration for soluble phosphorus removal of swine manure
Soluble phosphorus (P) removal by increasing swine manure pH was investigated in this study. Sodium hydroxide (1 M) was used to increase the manure pH from 6.5 to 9. Two aeration treatments...
