Extraction and recovery of chromium from electroplating sludge.
This work reports a study of the extraction and recovery of chromium from the wastes (class I dangerous) generated by a galvanic manufacturer. Commercial HCl at room temperature was employed, and the conditions of the extraction process were optimized according to a sequential experimental design, which also included the acid concentration and contact time as variables. The best extraction cond...
متن کاملReuse of textile effluent treatment plant sludge in building materials.
This study examines the potential reuse of textile effluent treatment plant (ETP) sludge in building materials. The physico-chemical and engineering properties of a composite textile sludge sample from the southern part of India have been studied. The tests were conducted as per Bureau of Indian Standards (BIS) specification codes to evaluate the suitability of the sludge for structural and non...
متن کاملCharacterization of chromium remediating bacterium Bacillus subtilis isolated from electroplating effluent
Chromium, especially chromium (VI), is the main pollutant of the tannery and electroplating industries. Cr (VI) is said to be a hazardous pollutant as it is highly toxic, mutagenic as well a carcinogen. Cr (VI) is mobile as it is soluble in nature. In our present study, indigenous bacteria that are tolerant to high concentrations of Cr (VI) were isolated from chromium contaminated electroplatin...
متن کاملPreliminary Assessment of Chromium Emissions from Chromium Electroplating Faci Lities
The United States Environmental Protection Agency (EPA) intends to add either chromium or hexavalent chromium to the list of hazardous air pollutants under Section 112 of the Clean Air Act. A preliminary assessment performed by EPA has identified several categories of stationary sources as emitters of significant quantities of chromium to the atmosphere and for which the proposal o f national e...
متن کاملIdentification of two flavin monooxygenases from an effluent treatment plant sludge metagenomic library.
Oxygenases are useful for the production of many industrially important molecules. Screening of an effluent treatment plant (ETP) sludge metagenomic library identified two clones encoding proteins, B1 and B2, with similarity to putative flavin monooxygenases from Mesorhizobium loti and Sphingomonas wittichi, respectively. The deduced amino acid sequences show only 20% identity, but both have a ...
