Abstract:

In this research, the ability of anaerobic and aerobic biological sludges to reduce and stabilize azo dye compounds was studied. Synthetic dye solutions and an industrial textile wastewater were both treated using anaerobic and aerobic biomass, separately and in sequential step-treatment processes. The primary objective was to reduce the wastewater color to an intensity that complies with the Virginia Pollutant Discharge Elimination System (VPDES) permit level. This level is set at 300 American Dye Manufactures Institute (ADMI) units. Further objectives were to achieve reductions in the to

Magister Scientiae - MSc (Biotechnology)<br>The treatment of mine water at the eMalahleni Water Reclamation Plant (EWRP) results in the production of large volumes of brine. Different brine management methods have been applied to dispose the brine but the evaporation pond method is regarded as the cheaper, most effective and less laborious method for brine disposal. Brine wastewater is pumped into the pond where it evaporates resulting in the mixture of salts. The rate at which evaporation occurs is influenced by many factors such as temperature, salinity, humidity and wind. Due to high salini

Barley straw, an agricultural byproduct, was identified as a potential adsorbent material for wastewater treatment as it offers various advantages such as abundant availability at no or very low cost, little processing cost and ability to biodegradation.

As temperature was increased, tune-ability through pressure manipulation was lessened. The effect of the NaOH concentration in the precipitation reaction was found to have an impact on CDL.

The optimum conditions obtained for treatment of different

碩士<br>國立交通大學<br>環境工程系所<br>100<br>Synthetic dyes are considered a high strength pollutant due to its significant contribution to suspended solids (SS), and chemical oxygen demand (COD) content in dye wastewater. Its high stability under sunlight and resistance to microbial attack also makes dye wastewater treatment problematic. Conventional wastewater treatments are proven inefficient in treating the dye wastewater to meet the standard set by the environmental protection bureau in Taiwan. Advanced oxidation processes (AOPs) including O3/UV, H2O2/UV, TiO2/UV and conventional Fenton’s process, w

碩士<br>淡江大學<br>水資源及環境工程學系碩士班<br>98<br>Advanced oxidation processes (AOPs) were wildly studied for dye wastewater treatment. Among the AOPs,Fenton process was the most discussed treatment technologies. However, Fenton process has following disadvantages including high dosage required and large amount of sludge generated. Therefore, the objective of this study is to study ultrasound-activation of persulfate to produce a very powerful oxidant, sulfate free radical, for dye wastewater treatment. Sodium persulfate is a stable and harmless material for environment. The results showed ultrasound can a

Abstract:

碩士<br>淡江大學<br>水資源及環境工程學系碩士班<br>97<br>The past researchers investigating dyeing wastewater focused mainly on Fenton which is one of Advanced Oxidation Processes (AOPs). However, Fenton has the problem of generating large quantity of waste sludge. Taking the advantage of higher temperature in dyeing wastewater, in this study sodium persulfate (Na2S2O8) was thermally activated with or without UV radiation to produce sulfate radical for decolorization of dyeing wastewater. The aim of this work is to investigate the effects of temperature and Na2S2O8 dosges on decolorization of dye by thermally act
