This study reviews recent research on the synthesis and application of titanium dioxide (TiO2)-based photocatalysts for environmental applications. The principles non-homogenous photo-catalysis include utilizing a solid semiconductor, such as Nano or macro, to form stable suspension (heterogeneous phase) at impact irradiation elevate reaction surface interface different phases in system. Recent...

MFC is a promising technology that can be used for simultaneous electricity generation and wastewater treatment. Power energy of ferroelectric cathodic ceramic, Li0.95Ta0.76Nb0.19Mg0.15O3 (LTNMg), has been measured in microbial fuel cells, integrating single chamber fed by industrial (CODinitial = 471 mg L?1, pHinitial 7.24 at T 27 °C). In this process, the mixed multicomponent oxide material p...

Solid dehumidification is one of the important components air-conditioning system. As an method solid dehumidification, performance and regeneration fixed-bed have impact on operation energy saving In view high air temperature humidity in South China, our design organically combines fixed beds, semiconductor refrigeration devices, foam ceramic insulation panels double-glazed windows. We designe...

The amount of used cooking oil waste is thrown into the sewer, which over time will compress sewer and can also pollute environment. Therefore, it would be good if this further processed bar soap that to wash clothes or other kitchenware. process making uses a cold process, does not use heating (stove). chemical NaOH. first stage purification crude oil. Purification done by soaking charcoal in ...

Heavy metals found in urban air with its toxic effects have a direct impact on human health. Selection of appropriate tree species and shrub refining capacity of heavy metals in urban areas can greatly reduce the toxic effects of these materials. This study aimed to identify the most suitable tree and shrub species of broadleaf evergreen, deciduous and coniferous refinement of heavy metals lead...

This paper presents the techno-economic assessment of CO2 Purification Unit (CPU) included in cement plants based on capture via oxy-fuel calcination. Two configurations, targeting two different outlet specifications (‘moderate’ and ‘high’ purity), have been optimized order to minimize increase clinker production cost due this process unit. Air infiltration rate is parameter with highest impact...

Abstract Aluminum and its alloys having lots of advantageous properties are among the most-used metallic materials. So, it is immense importance to find suitable processes methods leading high-quality purified Al melt. In this regard, there numerous challenges in achieving high purity melts, such as propensity react with air, oxygen, water vapor, presence a variety oxide, non-oxide, solid parti...

In the practical application of indoor air quality assurance system, it is difficult to detect fault valves, CO2 sensors and other components, resulting in substandard increased energy consumption. this paper, 16 conditions 1 no condition were simulated by Simulink simulation software for primary return conditioning system summer, a typical characteristic table was obtained. It found that PM2.5...
