denitrification of high- nitrate high- salinity wastewater is difficult due to plasmolysis and inactivation of denitrifiers at high salinity conditions. in this study, the effects of salinity and empty bed contact time (ebct) on simultaneous heterotrophic and sulfur based autotrophic denitrification of synthetic wastewater were evaluated in an up flow packed bed reactor .the reactor was filled ...

The application of energy storage technology can solve the problems randomness and volatility in development use renewable energy, such as wind solar effectively improve utilization. Rock heat is one primary forms sensible storage. efficiency capacity rock packed bed are important indicators to measure effect a system. This paper takes CO 2 heat-carrying medium broken granite grains matrix It e...

High-temperature packed-bed thermal energy storage represents an economically viable large-scale solution for a future fossil-free scenario. The present work introduces first-of-a-kind experimental setup of radial TES, and its performance assessment based on investigations. is analyzed set dimensionless criteria indicators. laboratory-scale prototype has capacity 49.7 kWhth working temperatures...
