The Effect of High Temperatures on Bnr Process Performance
نویسندگان
چکیده
The ever-expanding world-wide application of biological nutrient removal (BNR) technology is generating a greater appreciation for the performance of BNR processes under different operating conditions. This paper examines the effects of high process temperature on the biological phosphorus and nitrogen removal mechanisms and the sludge settling properties in BNR activated sludge processes. These effects are illustrated with data from three full-scale BNR facilities in which enhanced biological phosphorus removal (EBPR) failed, but nitrification and denitrification were maintained at mixed liquor temperatures of approximately 30°C.

This experiment was conducted to investigate the effect of in ovo feeding (IOF) and dietary feeding of Silybum marianum (SM) extract on the immunity of chicken under heat stress conditions. A total of 360 fertile eggs from a commercial broiler breeder (Ross-308) farm was used for in ovo feeding of 0, 100 and 200 mg/L SM water extract at day 17.5 of incubation. After hatching, 240 chicks were tr...
