  • Effect of Industrial Effluents polluting the river nile on growth, metabolism and productivity of Triticium aestivumand Vicia fabaplants
    Acta Botanica Hungarica, 2001
    Co-Authors: W. M. Shukry
    Abstract:

    Pot experiments using loamy soil were conducted to evaluate the effect of irrigation with Industrial Effluents on growth, uptake on growth, uptake of nutrients and yield of wheat (Triticum aestivumGiza 164) as a monocot and faba beans (Vicia fabaGiza 461) as a dicot plant. Also, irrigation by Industrial Effluents in combination with vesicular-arbuscular mycorrhiza (VAM) was used in trying to use a biological control to overcome the harmful effects of heavy metals pollution. Irrigation of plants with Industrial Effluents leads to marked changes in growth criteria depending on plant and/or the stage of growth. Industrial wastewater led also to marked changes in total carbohydrates and nitrogen in both shoots and roots. On the other hand, combination of Industrial waste water with VAM caused an increase in the total carbohydrates and total nitrogen in shoots and roots of both wheat and bean plants. The yield components in wheat and bean were significantly increased with Industrial Effluents, but the biochemi...

  • Incorporation of the Seasonal Variations in the Optimal Treatment of Industrial Effluents Discharged to Watersheds
    Industrial & Engineering Chemistry Research, 2013
    Co-Authors: Oscar Burgara-montero, José María Ponce-ortega, Medardo Serna-gonzález, Mahmoud M. El-halwagi
    Abstract:

    This paper presents a multiperiod optimization approach to the cost-effective reduction of the negative impact caused by discharging Industrial Effluents into watersheds. The model considers all discharges and extractions, as well as the chemical reactions carried out in the watershed, while accounting for the seasonal variability of the system through the year. The proposed model is based on a material flow analysis applied to a distributed treatment system for Industrial Effluents in a macroscopic water system. The problem is formulated as a multiobjective optimization model with the objectives of simultaneously minimizing the pollutant concentrations in the final catchment areas and the total annual cost of the waste-treatment units. The model selects the place to locate the treatment units and the type of treatment technology, as well as the Industrial Effluents treated in each period of the year, to satisfy the environmental regulations. Two case studies are presented to show the applicability of the...

  • nanocelluloses and their phosphorylated derivatives for selective adsorption of ag cu2 and fe3 from Industrial Effluents
    Journal of Hazardous Materials, 2015
    Co-Authors: Peng Liu, Pere Ferrer Borrell, Mojca Božič, Vanja Kokol, Kristiina Oksman, Aji P. Mathew
    Abstract:

    The potential of nanoscaled cellulose and enzymatically phosphorylated derivatives as bio-adsorbents to remove metal ions (Ag(+), Cu(2+) and Fe(3+)) from model water and Industrial Effluents is demonstrated. Introduction of phosphate groups onto nanocelluloses significantly improved the metal sorption velocity and sorption capacity. The removal efficiency was considered to be driven by the high surface area of these nanomaterials as well as the nature and density of functional groups on the nanocellulose surface. Generally, in the solutions containing only single types of metal ions, the metal ion selectivity was in the order Ag(+)>Cu(2+)>Fe(3+), while in the case of mixtures of ions, the order changed to Ag(+)>Fe(3+)>Cu(2+), irrespective of the surface functionality of the nanocellulose. In the case of Industrial effluent from the mirror making industry, 99% removal of Cu(2+) and Fe(3+) by phosphorylated nanocellulose was observed. The study showed that phosphorylated nanocelluloses are highly efficient biomaterials for scavenging multiple metal ions, simultaneously, from Industrial Effluents.

  • Effect of textile Industrial Effluents on seed germination of Lentil (Lens esculentum).
    Environment Conservation Journal, 2014
    Co-Authors: P. K. Bharti, Pawan Kumar
    Abstract:

    Textile Industrial Effluents are highly polluted in nature and vary in its compositions. In the adjoining agricultural area of textile industries sector, there is immense degradation of crops productivity being contaminated by irrigation through tubewells or directly from the effluent drain or village pond. The present paper deals with the physico-chemical parameters of textile Industrial Effluents and its impacts on germination and growth performance of Lentil (Masoor) Lens esculentum, (Family: Leguminoceae, Sub-family: Papillionateae). Seeds were found more tolerant against 25% concentrated effluent.

  • impact of Industrial Effluents on ground water and soil quality in the vicinity of Industrial area of panipat city india
    Journal of Applied and Natural Science, 2013
    Co-Authors: P. K. Bharti, Pawan Kumar, Vijender Singh
    Abstract:

    The present paper is aimed towards the assessment of heavy metal contamination of agricultural soil due to irrigation with contaminated ground water affected by textile Industrial Effluents at Panipat city in India. Samples of ground water and irrigated soils from textile Industrial area were analyzed for various heavy metals, viz. Mn, Ni, Fe, Cu, Cd, Pb and Zn, using Atomic Absorption Spectrophotometry. Metal transfer factors from ground water to irrigated agricultural soil and from soil to ground water were calculated for heavy metals. The findings deal with the distribution of heavy metals in ground water of Industrial area and irrigated agricultural soil. Transfer factors for heavy metals from effluent to ground water were observed to be 0.436, 1.180, 6.461, 2.401, 2.790, 3.178 and 0.634 for Cd, Cu, Fe, Mn, Ni, Pb and Zn respectively. These were found to be very high from ground water to agriculture soil due to the natural shale value of heavy metals in soil system. Thus, untreated Industrial Effluents can cause an environmental threat to ground water resources and affects soil quality and agricultural plant productivity.

  • seed germination of wheat triticum aestivum and the effect of textile Industrial Effluents on radical and hypocotyls lengths
    Environment Conservation Journal, 2012
    Co-Authors: P. K. Bharti, Pawan Kumar
    Abstract:

    Abstract Textile industries consume high quantity of water and release it as toxic Effluents after some colouring processes. However, some wastewater may be recycled as fertilizers in aquaculture and agriculture, horticulture after dilutions. But Industrial effluent of synthetic products like azo dyes may be harmful for germination and growth performance of crop seeds. The present paper deals with the physico-chemical parameters of textile Industrial Effluents and its impacts on germination and growth performance of Wheat, Triticum aestivum (Family: Gramineae/ Poaceae). Seeds were found more tolerant against 25% concentrated effluent.
