This review presents a comprehensive summary on applications of anaerobic membrane bioreactor (AnMBR) technology for industrial wastewaters in view of different aspects including treatability and filterability. AnMBRs present an attractive option for the treatment of industrial wastewaters at extreme conditions, such as high salinity, high temperature, high suspended solids concentrations, and ...
Zoonotic pathogens in land-applied dairy wastewaters are a potential health risk. The occurrence and abundance of 10 pathogens and 3 fecal indicators were determined by quantitative real-time PCR (qPCR) in samples from 30 dairy wastewaters from southern Idaho. Samples tested positive for Campylobacter jejuni, stx(1)- and eaeA-positive Escherichia coli, Listeria monocytogenes, Mycobacterium aviu...
Background and purpose: Industries are one of the main sources of producing wastewater accounting for 20% of water pollution. Treatment of dye wastewaters is one of the major challenges in textile industry. The aim of this study was to investigate the performance of advanced oxidation processes, Fenton-Peracetic acid and Photo-Fenton-Peracetic acid for removal of methylene blue (MB) dye from ...
A MicrosoftInternetExplorer4 Background and Objectives: Colored wastewaters are known as one of the most important sources of environmental pollutants. Having toxic chemicals and aesthetic problems has made treatment of these wastewaters very crucial. So far a number of methods such as electrochemical treatment, coagulation a...
AIMS Xanthan production by Xanthomonas campestris from several olive mill wastewaters (OMW) was investigated. METHODS AND RESULTS Maximum xanthan production of 4 g l(-1) was obtained in media with 50% OMW as sole source of nutrients. OMW storage decreased effluent quality for xanthan production. The range of effluent concentration for X. campestris growth and xanthan production varied dependi...
Certain wastewaters from the nonalcoholic sugar-sweetened beverage industry, particularly those discarded because of deficient bottling processes or those returned from the market because of quality constraints, exhibit chemical oxygen demand (COD) levels as high as 135000 mg of O2/L because of their sugar content: 60−119 g/L, depending on the beverage. Thus, treating such wastewaters before di...
The agricultural and forestry waste pine needle was selected to prepare the biochar which magnetized by Fe3O4 treat typical wastewaters of dye methylene blue (MB) carmine (P4R) in view problem quick increasing wastewater caused rapid development textile, printing dyeing industries, research result showed experimental values maximum adsorption capacity modified for MB P4R w...
In this chapter the fundamental aspects involved in biological treatment processes applied for the removal of nitrogen from wastewaters are described. A comprehensive review of the literature is provided including kinetic, microbiological and biochemical aspects of nitrification, denitrification and anammox, as well as key operational parameters affecting the processes. This information is rele...
Textile industry has been playing an important role in the global economy development, international business and trade. In China, textile industry is a traditional pillar industry and an important livelihood industry. The proportion of textile industrial output on GDP has risen to approximately 7% in recent five years. Currently, the ever increasing amount of carbon dioxide emissions, which ha...
Textile industries are one of the major contaminators of water and soil. Sodium is the only major cation present in textile wastewater due to high consumption of sodium salts in processing units. Many aquatic macrophytes are successfully used for phytoremediation of contaminated water. An attempt has been made to test the potential of Salvinia molesta in reduction of sodium from textile effluen...
