Direct Applicability

Three different activated carbons as effective adsorbents were prepared by digesting the stems of Cordia dichotoma, Albizia thompsonii and Polyalthia cerasoides plants in conc. H2SO4 for Cu2+ removal from wastewater. The sorption natures of these sorbents are optimized with respect to various physico-chemical characteristics for the maximum Cu2+ removal using simulated waters. Cordia dichotoma (CDAC), Albizia thompsonii (ATAC) and Polyalthia cerasoides (PCAC) activated carbons show good sorption capacities of values: 97.0, 76.8 and 66.7 mg/g, respectively in a wide pH ranges. Unlike that of other two activated carbons, Cordia dichotoma activated carbon is effective even in acid conditions, indicting its direct applicability to Cu-based industrial effluents which are generally acidic in nature. Interference of two fold excess of co-ions is minimal. The established extraction conditions for the removal of more than 95.0% from 10 ppm Cu2+ solution at room temperature (303 K) using CDAC as sorbent are: pH: 3-9; time of equilibration: 1 h; sorbent dosage: 0.100 g/100 mL; with ATAC: pH: 6-9; time of equilibration: 1.5 h and sorbent dosage: 0.125 g/100 mL; and with PCAC: pH: 6-9; time of equilibration: 2.0 h and sorbent dosage 0.50 g/100 mL. Spent adsorbents can be regenerated and reused until four cycles with minimal loss of adoption capacities. Thermodynamic studies revealed that the sorption is spontaneous and endothermic in nature. Further, the ΔH value for CDAC is 30.156 KJ/mol; it indicates the strong chemisorption and may be through reduction to Cu+/Cu and/or complex formation between Cu2+ and functional groups of the adsorbent. The ΔH values of other two activated carbons, ATAC and PCAC, indicated that the sorption is mainly physical with strong inclination towards chemical nature. Positive ΔS values of all the three sorbents, emphasizes the disorder or randomness at the solid-liquid interface and hence favourable conditions for more penetration of Cu2+ into the surface layers of the adsorbent and hence, more removal of Cu2+ ions. The negative ΔG values indicate that the sorption forces are good enough to cross the potential barrier at the solid-liquid interface and hence the process is spontaneous. The prepared three activated carbons were also successfully applied to industrial effluent and polluted lake samples.

Water pollution caused by leather industrial effluent discharges has become a troublesome phenomenon due to its negative impact on environmental health and safety. In this paper, the wastewater in the vicinity of Lawdar tannery areas was assessed in two years from October 2019 to June 2021 to determine physico-chemical parameters of industrial effluents of Lawdar tannery at four different area points. Tannery effluents were collected and all samples were analyzed in the laboratory and rated as no freshwater with parameters such as acidity and basicity, temperature, electrical conductivity, total dissolved solids, total suspended solids, chemical oxygen demand, biological oxygen demand, color, turbidity, hardness, alkalinity, and several positive and negative ions. The investigation showed that all physico-chemical parameters were higher than the standard disposal limits of discharged water quality. The findings of this research will assist the government and tanneries in the treatment of wastewater before discharging to the environment and monitoring the dump sites with regards to disposal arrangement of the tannery effluents and environmental assessment.

The Impact

Aim: This research work aimed to determine the impact of industrial effluent discharge on the physicochemical properties of Aleto Stream, Eleme and Rivers State. Study Design: Random sampling technique was applied in this study. The study area was divided into three sites; upstream, downstream all of Aleto Stream and Agbonchia Stream which serves for the control experiment. Water samples for eleven physical and six chemical parameters were collected in a Completely Randomized Design. Place and Duration of Study: This study was carried out on Aleto and Agbonchia streams at Eleme, Rivers State, Nigeria from 2017 to 2018. Methodology: Two samples were collected; one sample at the Aleto stream where the industrial effluent is being channelled into the stream and the other sample was collected from Agbonchia stream, which was used as a control. In the Aleto Stream, sampling was made at two points; point A (upstream) point B (downstream) and each of these points had their Physico-chemical properties tested while only one sample was collected from the Agbonchia Stream. Physico-chemical properties were analyzed in the samples using pH meter for pH, Turbidity meter for turbidity, Conductivity meter for electrical conductivity, phosphate by colourimetric method, total dissolved solids (TDS) and total suspended solids (TSS) by gravimetric method, biochemical oxygen demand (BOD) and chemical oxygen demand (COD) by standard method, chloride, alkalinity, dissolved oxygen (DO), calcium hardness, total hardness by titrimetric method, colour, odour and taste by sensory method. Results: Results obtained on the Physico-chemical properties had varying concentrations of Temperature, Total hardness, Chloride, Alkalinity, DO and Phosphate that were within world health organization (24)  and Federal Ministry of Environment (1991) permissible limits on both upstream and downstream with values ranging from 29.0-23.7oC, 360-125 mg/l, 120-100 mg/l, 36-30 mg/l, 4.9-4.4 mg/l, 1.92-1.2 mg/l respectively while Electrical conductivity, Turbidity, TSS, TDS, Calcium hardness, COD, BOD, Colour, Taste and Odour were above permissible limits on both upstream and downstream with values ranging from 1660-1700 mg/l, 83-112NTU, 82-80 mg/l, 910-914 mg/l, 1590-1900 mg/l, 100-165 mg/l, 4.36-3.88 mg/l respectively. The pH values ranged from 9.0-6.3 mg/l showing a result on the upstream to be alkaline while the downstream was slightly acidic. The increase in the above parameters above their permissible limits is as a result of the impact of industrial effluent discharges drained into the stream. This indicates that the stream is unfit for both human and aquatic inmates. Conclusion: Therefore, proper management of this effluent should be ensured and an acute test with lethal concentration (LC50) as the endpoint is recommended to determine the degree of toxicity of the effluent waste.

To study the effect of paper industrial effluent on chickpea (Cicer arietinum L.) along with different concentration (10%, 20% 40%, 60% 80% and 100%) and pure tape water as a control to compare the effect of paper industrial effluent for 7 days. Physico-chemical characteristics of paper effluent were analyzed in terms of pH, colour, order temperature, DO, BOD, COD, Total hardness, carbonated hardness. All the parameters were found to be higher than the WHO prescribed discharge limits for effluent. The amount of carbohydrate, protein and reducing sugar were comparable with control, their amount were increased at 40% in effluent treated seeds. The chlorophyll content was increased simultaneously with effluent concentration. From this study it is clear that the industrial effluent rich in organic matter and plant nutrients are finding their use in agriculture as cheaper way of disposal.

The study was carried out to investigate the spatial effects of industrial effluent on physico-chemical properties of soil around the textile industrial area of Bhaluka upazila, Mymensingh, from January to March, 2015. Total 15 soil samples were collected at 0m, 50m, 100m, 200m and 300m distances from the effluent discharging point. Soil texture, pH, electrical conductivity (EC), organic matter (OM), nitrogen (N), phosphorus (P), potassium (K), sulphur (S), sodium (Na) and heavy metal (lead, Pb and cadmium, Cd) content were investigated in this study. Soil pH, EC, OM and nutrient content of soil were higher at discharge point (at 0m) and lowest at 300m distance. The Pb content was maximum (36.9 ppm) at 0m and minimum (24.27 ppm) at 300m distance. The highest value (3.0 ppm) of Cd was observed at 0m and lowest value (2.8 ppm) was at 300m distance. All of the studied values were higher at the adjacent of industrial area and gradually decreased with distance.J. Environ. Sci. & Natural Resources, 8(2): 79-82 2015

Abstract Purpose: The present investigation was undertaken to evaluate the possibility of whether treated wastewater from industrial units could safely be used to irrigate crop plants and solve the problem of liquid effluent disposal in an eco-friendly manner. Methods: In this study select to evaluate the effects of effluents of textile, pharmaceutical and granite industry and on the germination (early growth) of selected forage crops like Sorghum bicolor, Pennisetum typhoideum and Hordeum vulgare. The present investigation involves the analysis of soil, water and plant analysis like chlorophyll, cartorenoids and growth. Results: The results revealed that pH, EC and chlorides and several other parameters were within the usual range of water used for irrigation purposes. The percentage of germination and vigor index was maximum for bajra and barley. The physico-chemical parameters of soil and wastewater were found to be within the usual range of tolerance limits for the industrial effluent on land prescribed by BIS except for TSS and hardness in some samples. The germination percentage and vigor index of jowar, bajra and barley were higher in granite industry water samples. The plant length of all crop samples had significant heights in all the samples. The total chlorophyll and carotenoid content were also found to be significant amounts in the leaf samples of all the crops grown in different water samples. Conclusion: Treated wastewater can be a prospective source of organic matter and nutrients that could increase the quality of soil, thus may be a beneficial alternative resource to freshwater for irrigation purposes in the offseason. Hence there are great possibilities for growing highly profitable forage crops using treated wastewater in the offseason.

Bauxite residue (red mud) is an industrial waste bye product of Alumina industry. It is toxic and highly alkaline in nature having heavy metals. Its disposal is the paramount environmental issue in Alumina industry. In the present study, bioremediation of red mud was carried out through cyanobacteria amendments and plantation. Two cyanobacterial species (viz. Phormidium and Oscillatoria) were found promising after studying their effect on physico-chemical characteristics of red mud. Seeds of selected tree species (viz. Dalbergia sissoo, Prosopis juliflora, Acacia auriculiformis, Pithecellobium dulce, Cassia siamia) were procured, and a nursery of these tree species was raised. Performances of two cyanobacteria (viz. Phormidium and Oscillatoria sps.) in combinations with PSB and VAM on red mud are very encouraging and hold considerable promise for bioremediation and revegetation of red mud. Inoculated seedlings of P. juliflora, P. dulce, A. auriculiformis, and C. siamia performed well for red mud revegetation.
