“…The mean value (mg/L) of the chromium after the bioremediation varies between 3.048±2.70 and 5.416±4.07. This is in agreement with the work of Maheshwari et al (2017) (22) in which the concentration of chromium decreased in biologically (immobilized Pseudomonas putida and Bacillus cereus) treated tannery wastewater. The relative potential or efficiency of the different masses of the C. kutsceri in remediating the chromium was in the order 10 g>25 g>20 g>5 g>15 g. A negative and no significant correlation (-0.29) exists between the masses of the C. kutsceri and the chromium.…”

“…The level of COD in the effluents from the tannery industry in Vaniyambadi, India was 860 mg/L (20) which was lower than that observed in the present study. The higher the COD value of wastewater, the more oxygen demand to discharge water bodies another researcher (22). Akan et al (2009) reported that a high COD value shows that the effluents have high oxygen demanding wastes which cause the depletion of Dissolved Oxygen (DO) which is a fundamental requirement for aquatic life.…”

In the present study, bioremediation potentials of indigenous bacteria (Corynebacterium kutsceri) in the treatment of tannery effluent was investigated. Industrial tannery effluent samples from Mamuda Tannery Industries in Challawa Industrial estate, Kano State, Nigeria were collected for a period of six months (August 2017 to January 2018) for the experiment. Bacteria were isolated from the effluents using serial dilution, immobilized on agar-agar and biochemical tests were carried out to identify the bacteria. Different masses (5 g, 10 g, 15 g, 20 g, and 25 g) of the identified bacteria were used in the treatment of 250 mL of the effluents. Temperature, pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Suspended Solid (SS), Total Dissolved Solids (TDS), sulfate, phosphate, nitrate, chloride, and some heavy metals (Cr, Fe, Mn, Ni, Pb, Zn, Cd, and Cu) were determined before and after treatment of the effluents with the bacteria. The pre-treatment analysis showed that the values, 29.50±4.68, and 5.35±1.57, were observed for temperature (O C) and the pH respectively. The levels (mg/L), 26.17±9.49; 3106±2753; 562±482; 444±507; 97.20±146.80; 268.34±411.01; 8.82±34.71 and 22.59±19.64 were observed for BOD, COD, SS, TDS, nitrate, sulfates, phosphate, and chlorides, respectively. The concentration (mg/L) of the heavy metals, before treatment (with the bacteria) were as; Cr (7.528±4.530); Fe (1.263±0.502); Ni (0.023 ± 0.021); Mn (0.277 ± 0.03); Pb (0.304 ± 0.20); Zn (0.058± 0.05); Cd (0.068±0.02) and Cu (0.012 ±0.02). The bacteria were identified to be Corynebacterium kutsceri. The post-treatment analysis showed that the COD (1376±248−2681±867 mg/L) has the highest value while Cu (ND −0.007±0.00 mg/L) has the lowest value. The post-treatment analysis using the different masses of the Corynebacterium kutsceri indicates that there is a great decrease in the levels of the physicochemical parameters and the heavy metals as well when compared with the levels observed at the pre-treatment analysis. The decrease could be attributed to, not only due to the increase in the exact mass of the bacteria but also to the multiplicity in the mass of the Corynebacterium kutsceri which subsequently increases the surface area for the remediation. The average high percentage reduction (70% to 100%) of these parameters and heavy metals implies that the Corynebacterium kutsceri has a higher potential for the treatment of effluents from the textile industries.

“…In the dry seasons, reduced dilution will lead to more serious pollution. The chromium in the tannery effluents comes from the commonly used chromium salt Cr2 (SO4)312(H2O), for tannery processes (Akan et al, 2007;Pawlikowski et al, 2006). The low Cr concentration in the tannery effluents during the 2013 campaign (Table 2.1.)…”

The median concentrations of Cr from tannery effluents and Zn from steel processing effluents were 26,600 and 155,750 µg/L, respectively, much exceeding emission guidelines.Concentrations of Cr were high in the Leyole river water (median: 2660 µg/L) and sediments (maximum: 740 mg/kg), Cu in the river water was highest at the midstream part of the Leyole river (median: 63µg/L), but a maximum content of 417 mg/kg was found in upstream sediments. Concentrations of Zn were highest in the upstream part of the Leyole river water (median 521µg/L) and sediments (maximum: 36,600 mg/kg). Pb concentration was low in both rivers, but, relatively higher content (maximum: 3,640 mg/kg) found in the sediments in the upstream of the Leyole river. Chromium showed similar patterns of enhanced concentrations in the downstream part of the Leyole River. Except for Pb, the concentrations of all heavy metals surpassed the guidelines for aquatic life, human water supply, and irrigation and livestock water supply. All of the heavy metals exceeded guidelines for sediment quality for aquatic organisms.Regarding nutrients, emissions from a brewery and a meat processing unit were rich in nutrients, with median concentrations of TN of 21,00-44,000 µg/L and TP of 20,000 -58,000 µg/L. These had an average apportionment of 10% and 13%, respectively, of the total nutrient loads. In the waters, higher TN concentrations were found from sub-catchments with largest agricultural land use, whereas highest TP was associated with sub-catchments with hilly landscapes and forest lands. Both the TN and TP concentrations exceeded standards for aquatic life protection, irrigation, and livestock water supply. Using specific criteria to assess model suitability resulted in the use of PLOAD. The model relies on estimates of nutrient loads from point sources such as industries and export coefficients of land use, calibrated using measured TN and TP loads from the catchments. The model was calibrated and its performance was increased, reducing the sum of errors by 89 % and 5 % for the TN and TP loads, respectively.The results were validated using independent field data.The findings of the research shows high loads of heavy metals and nutrients in rivers of the industrializing regions of Kombolcha, identified gaps in estimating heavy metals and nutrient pollution and in policy implementation. Recommended future research and policy development to address a number of key gaps in water quality protection measures include control of point and diffuse loads of heavy metals and nutrients from sources, and improvement in land managements and monitoring and regulation. viii ix Contents Summary vii Chapter 1: General introduction Chapter 2: Impacts and policy implications of heavy metals effluent discharges into rivers within industrial Zones: A sub-Saharan perspective from Ethiopia Chapter 3: Preventing sustainable development: policy and capacity gaps for monitoring heavy metals in riverine water and sediments within an industrialising catchment in Ethiopia Chapter 4: Eval...

“…Dying is considered as a key factor as it gives desired color in leather industry. It is worth to mention here that, large amount of total dissolved solid (TDS) as well as total suspended solids (TSS) and organic compounds are released to the wastewater through dyeing and re-tanning process [15][16][17]. Sever environmental anxiety could be appear due to the discharge of wet finishing effluents to water bodies which increase the environmental pollution and health risks.…”

Effective management of tannery effluent is needed for this time. Tanning industry is one of the worst industries from an environmental point of view, where is the prominent sources of pollution to the aquatic environment. Wetfinishing effluent is the most dangerous step, which generate the obnoxious effluent in the tanning industry. The conventional treatments of such waste showed deficiency to coop with the required limits of national regulatory standards. In the present study, an advanced oxidation technique based on modification of Fenton reaction combined with high porous nanomaterials was applied as an alternative treatment. Variable doses of H2O2, Fe +2 , CaO and pH were investigated to determine the optimum operating conditions. The obtained results indicated a good quality of the treated effluent. Residual concentrations of COD, BOD and TSS were 98.51%, 98.11% and 98.82% removal, respectively. The most obnoxious material (Cr) was highly removed (98.92%). Also, decolourization value (YCOL values) was obtained using Nano GO (99%) and/or active charcoal (88.08 %) with CaO. The residual effect of H2O2 was reduced by MnO2, SnO and Fe powder than sod. thiosulphate. The treated effluent could meet to the National regulatory standard for discharging into the sewerage systems with respect to the studied parameters.
