Growth of Spirulina maxima on Swine Waste

Bioresource Technology, 1993
Abstract The ability of Spirulina maxima to grow on aeration-stabilized swine waste and the use of this growth in the tertiary treatment of the waste was studied. Nutrient removal (total phosphorus, orthophosphates and ammonium) was used as an indicator of the depuration efficiency of the biological system.

Stabilization of Swine Wastes by Anaerobic Digestion

Environmental Technology (United Kingdom), 2007
The purpose of this study was to evaluate the efficiency of the anaerobic digestion to reduce the organic load of swine waste. Anaerobic digestion is a biological means of decomposition of manure in an oxygen-free environment, and has the advantage of producing a fuel gas (methane) and an odor-free residue rich in nutrients, which can be used as ...

Nitrification of swine waste

Canadian Journal of Microbiology, 1990
Complete oxidation of ammonia nitrogen (~1000 mg/L) to nitrite was observed in stabilized swine waste after 49 days in incubation at 400 rpm and 29 °C, only if 10% (v/v) activated sludge from a wastewater treatment unit and 1.5% (w/v) CaCO3, were added.

Estrogen Content of Dairy and Swine Wastes

Environmental Science & Technology, 2004
Naturally occurring estrogens in animal wastes may cause negative environmental impacts, yet their abundance in animal waste treatment and storage structures is poorly documented. To better quantify estrogen concentrations in animal wastes, multiple waste samples were collected from treatment and storage structures at dairy and swine facilities and ...
