AbstractThe adsorption by different silicate minerals of some heavy metals, present in industrial waste water, has been studied. These adsorbents (mainly clay minerals) are readily available, inexpensive materials and offer a cost-effective alternative to conventional treatment of wastes from the metal finishing industry. The results show that some mineral species are suitable for the purification of such residual waters down to the limits prescribed by current legislation concerning industrial wastes. The Langmuir model was found to describe such adsorption processes best. Sepiolite (Orera, Spain) has an adsorption capacity of 8.26 mg g-1 for Cd2+, the capacities depending on the metal adsorbed in the order: Cd2+ > Cu2+ > Zn2+ > Ni2+. This mineral shows the highest sorption capacity relative to the other minerals studied. Factors in the reaction medium such as pH and ionic strength influenced the adsorption process.

An investigation was made to ascertain heavy metals concentration in effluent samples collected from textile industries located at Bhaluka industrial area, Mymensingh, Bangladesh during August to November, 2013. Atomic absorption spectrometer (AAS) was used to evaluate the concentration of Zinc (Zn), Copper (Cu), Nickel (Ni), Cadmium (Cd), Chromium (Cr) and Lead (Pb) in the samples. The study revealed that heavy metals were present in variable amounts, where the concentrations of Cu (0.0405 ppm) and Pb (0.0003 ppm) were found lower than recommended level for industrial waste water. Among the present trace metals, the highest concentration (0.2-1.0 ppm) was found in Zn. Although the concentration is suitable for irrigation, it is unsafe for aquaculture. Besides, all of the wastewater samples possessed no Cr, Cd and Ni, which comprised less of the minimum acceptance level, indicating no possibility of contamination. However, comparing findings of this study with the safe limits for industrial wastewater, it can be concluded that the waste water of the study area except some sampling sites can be used for irrigation and aquaculture.

An in vitro study was conducted to isolate, identify and characterize heavy metal resistant bacteria from industrial waste water and to determine their tolerance capacity to cadmium and lead. Different morphological, physiological and biochemical tests were carried out to identify the bacterial isolates in the waste water. A total of eight bacterial isolates viz., Staphyllococcus intermedius, Pseudomonas aeruginosa, Bacillus cereus, Bacillus subtilis, Escherichia coli, Acinetobacter baumanii, Pseudomonas flavescens and Acinetobacter lwofii were identified from metal polluted tannery and steel industrial areas. Bacterial response to cadmium tolerance was determined by treating them with CdCl2 solution at a rate of 1, 2, 2.5 and 5 μg/ml. In case of lead tolerant bacteria, PbCl2 solution was applied at a rate of 0.05, 0.125, 0.2 and 0.5 μg/ml. Pseudomonas aeruginosa isolated from waste water of steel industries and Bacillus cereus from tannery area was found to be the most tolerant species to the different doses of cadmium and lead. The study indicated that Pseudomonas aeruginosa and Bacillus cereus could be good candidates for the treatment and elimination of heavy metals from industrial waste water. The present study may be helpful to the bioremediation of heavy metals in the contaminated environment. Dhaka Univ. J. Biol. Sci. 26(1): 29-38, 2017 (January)
