Experimental and Theoretical Investigation of Moisture Dynamics in Intermittent Drying of Rough Rice
Intermittent drying is a satisfactory technique for drying of heat sensitive grains especially rough rice. This method consists of two separate stages applied intermittently: drying and tempering. In this work, intermittent drying of rough rice is investigated both theoretically and experimentally. In order to characterize this process; a multi-scale model consisting of macroscopic and microsco...
متن کاملOn the Drying Dynamics in Biofilters
To a large extent the performance of biofilters relies on the presence of suitable amounts of water in order to provide conditions needed for microbiological degradation of pollutants to take place. In many cases breakdown of filtration performance occurs due to inappropriate water contents in the filter material. The present study focuses on the drying dynamics within such filters, which are m...
متن کاملStormwater Treatment Areas: Experiences with Nitrate Removal
Inorganic nitrogen is commonly found in three different forms: Ammonia (NH4), nitrite (NO2), and nitrate (NO3). Ammonia is a principle form of nitrogen found in urban wastewater and runoff especially from pastures and feedlots. According to Kadlec and Knight (1996), ammonia, or ammonium nitrogen, is the preferred nutrient form for most wetland plants because of its importance in plant growth. A...

متن کاملEffect of weathering on mobilization of biochar particles and bacterial removal in a stormwater biofilter.
To improve bacterial removal, a traditional stormwater biofilter can be augmented with biochar, but it is unknown whether bacterial removal remains consistent as the biochar weathers during intermittent exposure to stormwater under dry-wet and freeze-thaw cycles. To examine the effect of weathering on bacterial removal capacity of biochar, we subjected biochar-augmented sand filters (or simplif...
