In this work, the suitability of several techniques for monitoring a reverse-flow reactor system are studied. Reverse reactor systems are operated by periodically reversing the direction of the flow inside the reactor [1],[2]. One benefit of a reverse-flow configuration is that, for exothermic reactions, the system exhibit a heat-trap effect [3] where the temperature profile across the reactor ...
the down-flow hanging sponge (dhs) reactor, which was developed for post-treatment of effluent from up-flow anaerobic sludge blanket (uasb) process treating sewage, uses polyurethane sponge as media to retain biomass. wastewater is trickled from the top of the reactor and purified by microorganisms retained both inside and outside of the sponge media as the wastewater flows vertically down thro...
A novel wastewater treatment system has been developed, utilizing an oxygen-rich algal liquid to supply oxygen to an aerobic biofilm reactor. Aerobic treatment of wastewater takes place in a Moving Bed Biofilm Reactor, where the aerobic biomass which breaks down organic and nitrogenous pollutants grows as a biofilm on floating carriers. Algae grown in an open raceway pond produce oxygen through...
In the present work, the performance of a tubular electrochemical reactor operated with three different inlets (central, lateral and tangential) was evaluated. Fluid flow simulations through the electrochemical reactor were performed using computational fluid dynamics (CFD). The steady state fluid flow was simulated to visualize the velocity field behavior along the reactor for each different i...
Self-aerated flows in flat chutes are encountered downstream of the bottom outlet, spillways with a small slope and storm waterways. In present study, development self-aeration chute flow is described new experiments performed long pressure outlet for different discharge rates. The distribution air concentration, time mean velocity fluctuation direction self-aerated developing region—where bubb...
A mesophilic unsaturated flow (trickle bed) reactor was designed and tested for H2 production via fermentation of glucose. The reactor consisted of a column packed with glass beads and inoculated with a pure culture (Clostridium acetobutylicum ATCC 824). A defined medium containing glucose was fed at a flow rate of 1.6 mL/min (0.096 L/h) into the capped reactor, producing a hydraulic retention ...
Carbonation of magnesiumand calcium-silicate minerals to form their respective carbonates is one method to sequester carbon dioxide. Process development studies have identified reactor design as a key component affecting both the capital and operating costs of ex-situ mineral sequestration. Results from mineral carbonation studies conducted in a batch autoclave were utilized to design and const...
