Studies on Recovery of Chromium Form Tannery Wastewater by 29 Studies on Recovery of Chromium from Tannery Wastewater by Reverse Osmosis
Chromium (Cr) is the most important element used to leather industry is still considered to be the most important industries which pollute the environment by chromium metal. Removal of heavy metals dissolved at low concentrations in water and wastewaters is often a problem that can be solved in different ways. This paper describes a study conducted to determine the recovery of chromium from tan...
متن کاملRemoval of Chromium (VI) in Tannery Wastewater by Bacillus cereus
Bacillus cereus was used to remove Cr(VI) in tannery wastewater containing medium at different initial Cr(VI) concentration, temperature, pH and biomass to get better conditions. At the optimum condition, the Cr(VI) in tannery wastewater was treated by each component of the cells to detect the capacity of the components for the Cr(VI) reduction. Also, the Bacillus cereus was continuous cultured...
متن کاملContinuous removal of chromium from tannery wastewater using activated sludge process—Determination of kinetic parameters
The activated sludge has been acclimatized with chromium (VI) ions from 5 mg/L to 20 mg/L. It is observed that the chromium removal percentage, COD removal and mixed liquor suspended solid (MLSS) decrease with the increase in dilution rate. Maximum food to microorganisms ratio (F/M) is found to be 0.19. When initial metal ion concentration increases from 5 mg/L to 20 mg/L, the chromium removal ...
متن کاملAdsorption of Chromium (VI) by a Low-Cost Adsorbent Prepared from Tamarind Seeds
The presence of toxic heavy metals such as chromium (VI) contaminants in aqueous streams, arising from the discharge of untreated metal containing effluents into water bodies, is one of the most important environmental problems. Adsorption is one of the effective techniques for chromium (VI) removal from wastewater. In the present study, adsorbent is prepared from tamarind seeds and studies are...
متن کاملDetermination of Chromium in Tannery Effluent and Study of Adsorption of Cr(VI) on Sawdust and Charcoal from Sugarcane Bagasses
Spectrophotometric method using diphenylcarbazide as a colour developing reagent has been used to analyze the chromium content in tannery effluent located in Bara and Parsa districts of Nepal and Sirsiya River which is an ultimate drainage of these waste water streams. The adsorption of hexavalent chromium from aqueous solution onto formaldehyde treated sawdust and charcoal of sugarcane begasse...
