Since the present researches on pollution control for textile printing & dyeing industry are mainly focused on qualitative description up to now, instead of special quantitative analysis, based on the census data of pollution sources, this paper adopts literature collection method and single-factor variance components method for continuous variables to identify the factors influencing cost for ...

Pectinase enzymes are one of the commercially important enzymes having great potential in various industries especially in food industry. Pectinases accounts for 25 % of global food enzymes produced and their market is increasing day by day. Therefore, the exploration of microorganism with novel characteristics has always been the focus of the research. Microorganism dwelling in unique habitat ...

Considering both the volume and the effluent composition, the textile industry wastewater is rated as the most polluting among all industrial sectors. Important pollutants are present in textile effluents; they are mainly recalcitrant organics, colour, toxicants and inhibitory compounds (Khelifi et al., 2008). Textile industries however, have caused serious environmental problems because of the...

Starch, as the major nutritional component of our staple crops and a feedstock for industry, is a vital plant product. It is composed of glucose polymers that form massive semi-crystalline granules. Its precise structure and composition determine its functionality and thus applications; however, there is no versatile model system allowing the relationships between the biosynthetic apparatus, gl...

BACKGROUND Recently, the pharmaceutical manufacturing industry has been growing rapidly in many countries in the world, including in Arab countries. Pharmaceuticals reach aquatic environments and are prevalent at small concentrations in wastewater from the drug manufacturing industry and hospitals. Such presence also occurs in domestic wastewater and results from the disposal of unused and expi...

To reduce waste and wastewater pollution and to improve the utilization rate of resources in the pig-industry chain, a circular economy of the chain can be developed. The key to constructing the circular economic system of the pig-industry chain is to determine the path of the cyclic materials and to design reasonable wasteand wastewater-treatment capacities. This paper focuses on the treatment...

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...

Pharmaceutical industry often generates highly toxic wastewater and sludge depending upon the used manufacturing process and season. The high BOD to COD ratio of this particular wastewater makes biological treatment difficult. Hence chemical treatment proves to be a useful option. Fenton’s reagent is used in the treatment of pharmaceutical industry wastewater in this study. The ferrous and hydr...
