Mathematical Modeling of Reactor for Water Remediation
Water is one of the most profuse, required of compounds and it is the most important fundamental of earth and the fluids of most living. Unfortunately, the water source is scarce and water quality has been reduced because of inappropriate waste clearance practices and casual hazardous chemicals spillage. Consequently, water remediation is important, which the water pollution is inhibited and the polluted water remedied in order to keep community, environment and human health from harm. Almost, the water remediation is performed in reactors or columns under multiphase reactive flows like gas‐liquid flow, immiscible liquids flow, solid‐liquid flows. The understanding such flows due to the complexity of multiphase flows is not completed yet. Columns, reactors and fluidized bed reactors are widely used in water remediation. The fluidized bed reactor contains a bed of solid particles that at low flow rates of fluid, these particles are stationary, while fluidization occurs when at high flow rate of fluid, the drag force exceeds the gravity force. Another reactor that vastly used in water remediation is H 2 O 2 /UV reactor, but the operating cost of this type of reactor is high, because H 2 O 2 is costly agent and needs regular monitoring and post treatment of the surplus peroxide imposes further costs. These reactors can be used only for small‐scale treatments. The promising alternative for H 2 O 2 /UV reactors are VUV/UV reactors, which the need of H 2 O 2 is eliminated in these reactors and then the operating is cheaper and more efficient for environmental considerations. Researchers have showed that the efficiency of these reactors strongly depends on flow characteristics. In the last two decades, numerical modeling and computational fluid dynamics (CFD) have shown a great potential as powerful and cost‐efficient tools to troubleshoot existing disinfection contactors and improve future designs for the water and wastewater treatment utilities. To remedy of water, modeling and design of reactor is important. This chapter prepared an overview of most commonly modeling and simulation of reactors for water remediation. These reactors are including water purification, electro‐synthesis of chemical substances, energy storage and wastewater treatment and so on. Furthermore, design of new reactors with modern geometry and some parts of existing cells, were investigated and impacts of some parameters on their performance were discussed.
