Anaerobic digestion is a well-established technology that valorises organic wastes to produce renewable energy as biogas. The ammonia released during this process can be inhibitory if it exceeds threshold concentration. Additionally, harmful environmental pollutant and also source of energy, thus establishing need for the recovery ammonia. Gas-liquid stripping one such widely researched recover...

Microalgae are able to convert nutrients (nitrogen and phosphorus) from wastewater into biomass and bio-products, thus improving the sustainability of wastewater treatment. In High Rate Algal Ponds (HRAP), biomass productivity and water treatment efficiency are highly dependent on environmental parameters such as temperature, light intensity and photoperiod. The influence of temperature and pho...

the purpose of this study is determining of some immunity and blood serum parameters in brood stock and grower fish before and after of stripping to evaluate the effect of breeding physiological changes on immunity and serum indexes. in this study 15 male trout fish (oncorhynchus mykiss) including 5 in the stage of grower, 5 before stripping and 5 after stripping randomly were considered. blood...

For a packed bed in a distillation column, fmax is the maximum fractional liquid maldistribution that can be tolerated in a parallel column model whilst still being able to achieve the design separation. It was previously shown that fmax can be easily calculated from a conventional column simulation output and it is a measure of the sensitivity of a packed bed to maldistribution. In this paper,...

Purpose The effect of bolt stripping failure on the ductility steel end plate beam-column connections has received relatively little investigation to date. objective with present work is establish a validated numerical model at elevated temperatures, which predicts mechanical behaviour and modes observed in experimental tests including failure. Furthermore, FE was used investigate both rotation...

Distillation is the most widely used but the most energy-consuming separation process in the chemical industry. The internally Heat-Integrated Distillation Columns (HIDiC) are one of the promising alternatives of the conventional distillation processes to reduce the energy consumptions in chemical processes. The HIDiC has a similar structure to a heat exchanger. The rectifying section is contac...
