Our previous report showed gastric mucosal surface pH was determined by alkali secretion at intragastric luminal pH 3 but by acid secretion at intragastric pH 5. Here, we question whether regulation of mucosal surface pH is due to the effect of luminal pH on net acid/base secretions of the whole stomach. Anesthetized rats with a gastric cannula were used, the stomach lumen was perfused with wea...

to study the feasibility of anaerobic filter in raw sewage and slaughter house wastewater treatment, slaughter house wastewater treatment, a batch flow pilot plant was designed. in phase one, with a detention time of 3-days and no mixing, the maximum reduction in cod was 23%. in the second phase, with a detention time of 2-days and complete mixing, glucose was added to the raw sewage, the reduc...

A global freshwater pollution catastrophe is looming due to pollutants of emerging concern (PECs). Conventional water treatment methods are limited in removing PECs such as pharmaceuticals and dye house effluent from aquatic systems. This study provides an effective potential solution by developing innovative wastewater method based on solar-light-responsive semiconductor-based photocatalysts. ...

Studies were carried out on the decolorization of azo dyes by Bacillus species from effluent of textile industries. About 10 bacterial strains were isolated from the effluent of textile industries, Bacillus sp. showed remarkable ability in decolorizing the widely utilized azo dyes. Phenotypic characterization and phylogenetic analysis based on 16S rDNA sequence comparisons indicate that these s...

The present work was directed toward the successful ability of electerocoagulation to remove color from synthetic and simulated textile effluent by aluminum/iron electrodes. Two representative reactive dyes were selected for the synthetic dye system, a black dye alone and mixed dye (black, blue, red, 1:1:1 vol/vol). Several important operating parameters such as electrode material, initial pH(3...

Rapid industrialization has necessitated the manufacture and use of different chemicals in day to day life. Water is life but now-a-days due to advancement in industrialization, it a spoiling a lot. In the present study, an attempt was made to examine the isolation and identification of Bacillus species from marine soil, Nagapattinum seashore, Tamil Nadu, India. Dyes are collected from in aroun...

The present work presents a strategic sequential experimental planning to evaluate the removal of methylene blue dye from aqueous medium by electrocoagulation combined with dissolved air flotation. Effect electrode pairs, spacing, contact time, initial pH, voltage, and pressure were optimized according following response variables: color, final turbidity, removal. best-achieved conditions were:...

In the present work, rock dust was evaluated as an adsorbent and heterogeneous photocatalyst in discoloration of Basazol Yellow 46 L dye, which is widely used dyeing molded pulp packages. Although produced large quantities quarries a byproduct exploration, little known about its application photocatalyst. Rock characterized by XRD, SEM/EDS, photoacoustic spectroscopy, N2 physisorption had photo...

Water contamination with large amounts of industrial textile coloured effluents is an environmental concern. For the treatment of textile effluents, white-rot fungi have received extensive attention due to their powerful capability to produce oxidative (e.g., ligninolytic) enzymes. In addition, other groups of fungi, such as species of Aspergillus and Trichoderma, have also been used for textil...

Article history: Received 30 August 2017 Accepted 18 September 2017 Available online 02 October 2017 The textile industry is a field which has strong environmental impacts due its high consumption of water and emission of pollutants, specially the dyes. The dyes are organic or synthetic substances which alter the physicochemical characteristics of the water body in which they are released, incr...
