Most biological nutrient removal (BNR) wastewater treatment plants are required by permit to significantly reduce total nitrogen (TN) and total phosphorus (TP). In Florida, advanced wastewater treatment (AWT) permit limits are as stringent as 3 mg/L TN and 1 mg/L TP as annual average or maximum month values. Consistently meeting low nutrient permit limits presents several operational challenges...

Colombia’s main water bodies have been seriously polluted due to mismanagement of domestic, agricultural, and industrial wastewater. While the country’s wastewater infrastructure has expanded in the past decades, the selection of the existing treatment technologies has excluded important aspects that could compromise their sustainability. Colombia and similar countries are in great need for ine...

The domestic use and industrial activity, especially in developing countries, produce large amount of wastewater. This wastewater when disposed into natural channels may lead to high pollution risk. There are different methods for wastewater treatment. One of them is Advanced Oxidation Processes (AOPs), still it has some limitations. The present work has been concentrated on the degradation of ...

Title of Document: FATE OF BACTERIAL AND VIRAL INDICATORS IN AN ADVANCED WASTEWATER TREATMENT PLANT Chung-Che Liang, Master of Science 2013 Directed By: Professor Krista Wigginton Department of Civil and Environmental Engineering Wastewater treatment plants (WWTP) are natural aggregators of pathogenic organisms due to the waste they treat. This study examined the fate of two bacterial indicator...

The paper industry is adopting zero liquid effluent technologies to reduce freshwater use and meet environmental regulations, which implies closure of water circuits and the progressive accumulation of pollutants that must be removed before water reuse and final wastewater discharge. The traditional water treatment technologies that are used in paper mills (such as dissolved air flotation or bi...

Application of Granular Activated Carbon (GAC) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. Because of entering poisonous compounds such as furfural, phenol and sulfides into the oily wastewater of Tehran refinery, biological aeration basins of wastewater treatment unit may not have the desired performance of COD reductio...

The aim of this study was to find optimum dose of ferrous sulphate and hydrogen peroxide in Fenton oxidation process for treatment of dyeing wastewater. Fenton process is the advanced oxidation method used mainly for COD and colour removal. Experiments are done on synthetic wastewater prepared from three different dyes; acidic, disperse and reactive; and also effluent obtained from industry. Th...

At present, the use of water in each country increases sharply, which also brings increasingly prominent environmental pollution problems. A large amount wastewater is discharged into body, seriously pollutes environment. Wastewater treatment has become focus global protection workers. Among them, advanced oxidation technology based on sulfate radical used to treat refractory organic pollutants...

Advanced treatment capabilities enable cities to augment drinking water supplies with purified wastewater. This image shows treated water feeding into a microfiltration unit, part of the Orange County Groundwater Replenishment System.
