A Study on removal of chromium from tannery effluent treatment of chrome tanning waste water using tannery solid waste
This study illustrates the process of removal of chromium from chrome tanning waste-water by fly ash which was drive from chrome shaving dust. This experiment was carried out in a batch process with laboratory prepared adsorbent samples and chrome tanning water collected from local tanneries. The influence of various factors likes adsorbent doses, contact time, and initial concentration of chro...
متن کاملHexavalent chromium reduction by bacteria from tannery effluent.
Chromium is generated from several industrial processes. It occurs in different oxidation states, but Cr(III) and Cr(VI) are the most common ones. Cr(VI) is a toxic, soluble environmental contaminant. Some bacteria are able to reduce hexavalent chromium to the insoluble and less toxic Cr(III), and thus chromate bioremediation is of considerable interest. An indigenous chromium-reducing bacteria...
متن کاملStudies on Chromate Removal by Chromium-Resistant Bacillus sp. Isolated from Tannery Effluent
A chromate-removing strain was isolated from spent chrome effluent and identified as Bacillus circulans strain MN1. The isolated strain was studied for resistance to Cr (VI) and its ability to remove Cr (VI). The strain was found to tolerate Cr (VI) concentration as high as 4500 mg/L, but the cells growth was heavily influenced when initial Cr (VI) concentration was increased between 1110 mg/L ...
متن کاملBiosorption of Chromium from Tannery Effluent Using Biomass of Sargassum
The release of chromium into water bodies is one of the major concerns of tannery industries. The present work deals with the determination of Chromium removal capacity of powdered biomass of Sargassum wightii (Greville) in synthetically prepared as well as real tannery effluent. The maximum adsorption was obtained after 12 hours of exposure at pH-4, in 8g/L biomass concentration of the seaweed...
