Greenhouse gas (GHG) emission can become a limiting factor in livestock farming development. Animal manure management systems in Taiwan differ from the model of the Intergovernmental Panel on Climate Change (IPCC) to represent the Far East and Asian region. This study was undertaken to establish GHG production data from anaerobic livestock wastewater treatment processes in Taiwan, and to clarif...
Pelareh Dairy Industry (PDI) is located in the west of Iran. The aim of the present study was to assess the quality and quantity of PDI wastewater and compare the results with the regulations. PDI has a wastewater treatment plant that consists of sewage collection system, screening system, equalization tank, clarification tank, anaerobic system for pretreatment, activated sludge processing, dis...
It has been proposed that livestock production effluents such as wastewater, airborne dust and manure increase the density of antimicrobial resistant bacteria and genes in the environment. The public health risk posed by this proposed outcome has been difficult to quantify using traditional microbiological approaches. We utilized shotgun metagenomics to provide a first description of the resist...
background: wastewater produced by a dairy in sanandaj is a major source of environmental pollution threatening the city. the dairy uses activated sludge treatment to remove organic pollution from the wastewater. the present study evaluated the performance of this process and its compliance with national requirements for chemical oxygen demand (cod), biochemical oxygen demand (bod), and total s...
Textile industry processes are among the most environmentally unfriendly industrial processes; because, they produce color wastewater that is heavily polluted the environment. Therefore, textile industry wastewater has to be treated before being discharged into the environment. In this study, experiments were conducted for different process parameters like nutrient dosage and dilution ratio aga...
Using algae as a feedstock for biodiesel has been considered for a number of years, but it has always had limitations, due mainly to the production methods used to grow and harvest the algae. In this project, we propose a novel attached growth method to produce the algae while recycling dairy farm wastewater using the microalga Chlorella sp. The first part of the work provided a feasibility stu...
enzymatic extract preparation from pseudomonas aeruginosa km110 under accession no. hq730879 with lipase activity (0.3 u/ml), was used to perform enzymatic hydrolysis pretreatment of a synthetic dairy wastewater with 1000 mg/l total fat content. the pretreatment was optimized for 48 h hydrolysis time, at 45æ% c with 10% v/v enzymatic extract. the biological treatment of synthetic dairy wastewat...
105 ABSTRACT: The isolated fungi species of different kinds from chromium contaminated soil sites located in Nagalkeni, Chennai were used for reducing chromium(VI) in a tannery industry wastewater of Nagalkeni, Chennai. The experiments were conducted to know biosorption potential of isolated fungi species for removing chromium(VI) in a tannery industry wastewater against the different pH, fungi...
