Background The Solids Thermophilic Aerobic Reactor (STAR) was investigated for the initial treatment of all biodegradable solid wastes that would be generated in a crewed mission, including inedible plant wastes, paper, fecal matter, and food wastes. STAR operates similarly to the autothermal thermophilic aerobic digester (ATAD) currently in use in a number of wastewater treatment plants. The p...

Industrial milk powder production applies the principle of a spray dryer. In powdered industry using dryer, there are still some problems in actual conditions such as fouling heat exchanger and losses. Losses lost material or time so that result losses for company. The importance finding soon possible it is to make solution initially unknown wasted vain can be used finished good. Steps taken re...

Several industrial fields require mixing and mechanical agitation processes. This operation is mainly used to enhance heat mass transfer inside stirred tank systems improve the degree of homogeneity obtain a high-quality final product. The main goal this research paper analyze thermal hydrodynamic behavior non-Newtonian nanofluid (Bingham–Papanastasiou–Al2O3) symmetrically tank. A 3D numerical ...

energy consumption is very high in greenhouses mainly due to off-season production. the main source of its energy supply is fossil fuels. due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. in this research, a solar heating system, equipped with a concentrat...

— Coupled Tank system used for liquid level control is a model of plant that has usually been used in industries especially chemical process industries. Level control is also very important for mixing reactant process. This survey paper tries to presents in a systemic way an approach predictive control strategy for a system that is similar to the process and is represented by two liquid tanks. ...
