  • Treatment of leather industrial wastewater via combined advanced oxidation and membrane filtration

    The liming/unhairing operation is among the important processes of the leather industry. It generates large amounts of effluent that are highly loaded with organic hazard wastes. Such effluent is considered one of the most obnoxious materials in the leather industry, causing serious environmental pollution and health risks. The effluent is characterized by high concentrations of the pollution ...

  • An Assessment of Environmental Concerns in the Leather Industry and Proposed Remedies: a Case Study of Pakistan

    In the leather sector different types of finished leather is prepared from salted raw skins. There are about 596 tanneries in Pakistan in the formal sector and more than 90% of their product is exported. About 130 different types of chemicals are used in leather manufacturing which ranges from common salt (Sodium Chloride) to very expensive Chrome Sulphate. The chrome tanning process is widely ...


  • Environmental pollution generated from process industries in Bangladesh

    The sources of environmental pollution in process industries in Bangladesh are discussed. Total pollution load into environment (i.e., into air, water and land) generated from process industries is determined and presented using industrial pollution projection system (IPPS) developed by the World Bank. Most polluting industries in Bangladesh are identified and ranked. The projection of this ...

  • Pollution prevention by salt free preservation of raw goatskins through stepwise drying

    An alternative process to traditional salt curing of skins has been explored in this study. A stepwise drying of raw goat skins under vacuum in the temperature range of 30-45°C resulted in acceptable moisture level of 19-20%. The dried skins were found to have a shelf life of more than five weeks. The experimental skins were processed to leather and the physical properties were tested and found ...

  • Analysis of the contributions of pollution to industrial discharge categories in Korea using the Modified Toxic Weighting Factor

    In 2007, 45,163 domestic industrial direct/indirect discharge sources were registered in Korea, which have been categorized into 82 divisions based on the characteristics of their products, raw materials and wastewaters. The purpose of this study was to set priorities using a risk assessment of pollutants toxic weighting for each industrial category with respect to pollution prevention and ...

  • Intensive odor - Case Study

    Example: Waste disposal for tanneries Similar tasks: Leather industry, fish cannery, bio-ethanol production, coffee roasters Various leather producers operating a tannery founded a joint waste disposal company which produces valuable proteins from the waste. The refining of the raw material and the treatment with ammoniac compounds produces malodorous waste gases. As these contaminants ...

  • Quantification of transient flux decline during membrane separation of tanning effluent from tannery

    Cake filtration model is described to establish/quantify transient flux decline mechanism for membrane separation of tanning effluent collected from tannery. Two membrane operations, Nanofiltration (NF) followed by Reverse Osmosis (RO), are adopted to treat tanning effluent. The experiments are conducted in a continuous cross-flow mode of operation. Three-flow regimes, namely, laminar, laminar ...

  • Efficiency evaluation of textile basic dye removal from water by nanofiltration

    Industrialization and urbanization have resulted in rapid deterioration of water quality. The scientific evidences prove that the effluents released from different industries e.g. textile, leather, paint etc. comprise of different hazardous and toxic compounds, some of which are known carcinogens and others probable carcinogens. The emergence of industrial centers without a corresponding growth ...

  • Energy from waste: the recycling of limed fleshings

    Leather products have been around a long while - there are those who claim that it is the second oldest business in the world. Going back a few millennia, when our earliest ancestors decided that sitting on hard rock was not a soft option, they turned to other materials in order to create more comfortable seating, as well as warmer bedding and improved clothing. Animal skins became the fabric ...

  • Biological Reduction of Hexavalent Chromium: A Potential Strategy for the Bioremediation of Cr(VI)-Pollutied Wastewater

    ABSTRACTThe potential for biological treatment of Cr (VI)- polluted wastewaters has attracted increased interest, because this alternative is more efficient and less expensive than conventional physicochemical treatments. In this work, a microbial enrichment capable of tolerating and reducing high Cr(VI) was isolated. The kinetic parameters of the Cr(VI) reduction process indicate that the ...

  • Briquettes - A Perfect Replacement of Fossil Fuel for Manufacturing Facilities

    Large scale manufacturing units highly depend on fossil fuel, which not just pollutes environment, but also increases their overall cost. Briquettes make a perfect substitute of fossil fuel. Industrial briquetting press can produce high quantity of briquettes to meet with huge demand. Find out other benefits of briquettes for manufacturing units. Effective waste management as well as environment ...

  • An Introduction to Bioremediation and its Applications

    A variety of toxic chemicals, metals, and effluents are created and used in industrial processes. These elements need to be degraded to ensure that they do not harm the environment when disposed. A specialized process and equipment are required to perform this task. This is where bioremediation comes in. What is Bioremediation, and what are its Types? In simple ...

  • How can we use Biomass as an energy source?

    Any Country which has Agriculture or Forestry waste available has big scope to use biomass as an energy source. We can use Biomass as fuel in its loose form but we can also bind them in solid fuel for more energy consumption. Any biomass like forestry waste, Agriculture waste or any other biomass waste can be recycled into solid biomass fuel/Bio coal/White coal/Briquette. What is ...

  • Lumen Recommendations for Common and Industrial Work Spaces

    Lumen Recommendations for Common and Industrial Work Spaces Light brightness requirements for common and industrial spaces differ greatly. To achieve consistent, bright environments, the fixture’s luminous flux (or lumen [lm], which is the SI unit of luminous flux) must be taken into consideration. By definition, the term “luminous flux” (lx) refers to ...

  • An odor predictive model for Rendering applications

    Abstract The rendering process consists of crushing and heating animal remains to produce by-products. The U.S. produces approximately 30 billion pounds of inedible animal by-products annually, exporting a market value of US$ 1.5 billion. Benefits of the rendering process include reducing total waste material, and helping the livestock industry stay competitive over vegetable protein ...
