To address the challenge the team at ...


  • Anodic oxidation of slaughterhouse wastewater on boron-doped diamond: process variables effect

    A non-sacrificial boron-doped diamond electrode was prepared in the laboratory and used as a novel anode for electrochemical oxidation of poultry slaughterhouse wastewater. This wastewater poses environmental threats as it is characterized by a high content of recalcitrant organics. The influence of several process variables, applied current density, initial pH, supporting electrolyte nature, ...

  • Performance of airlift MBR for on-site treatment of slaughterhouse wastewater in urban areas of Vietnam

    In many cities in Vietnam, wastewater generated in slaughterhouses is normally discharged directly into surface waters without treatment. Management of slaughterhouse wastewater (SHWW) is difficult due to the lack of infrastructure for conveyance to centralized facilities. On-site treatment presents one cost-effective way of managing SHWW compared to mass improvement of infrastructure. This ...

  • The potential of ultrasonic membrane anaerobic systems in treating slaughterhouse wastewater

    Direct discharge of slaughterhouse wastewater causes serious environmental pollution due to its high chemical oxygen demand (COD), total suspended solids (TSS) and biochemical oxygen demand. In this study, an ultrasonic-assisted membrane anaerobic system was used as a novel method for treating slaughterhouse wastewater. Six steady states were achieved, using concentrations of 7,800–13,620 mg/l ...

  • Managing waste from confined animal feeding operations in the United States: the need for sanitary reform

    Confined food-animal operations in the United States produce more than 40 times the amount of waste than human biosolids generated from US wastewater treatment plants. Unlike biosolids, which must meet regulatory standards for pathogen levels, vector attraction reduction and metal content, no treatment is required of waste from animal agriculture. This omission is of concern based on dramatic ...

  • Reusing date seed residues as a low cost adsorbent for slaughterhouse wastewater purification

    Date seeds were found to be as effective adsorbents as activated carbon for the removal of organics from slaughterhouse wastewater. Experiments were successfully employed to attain the maximum amount of COD adsorption. The maximum adsorption capacity were 53 and 60 mg/g for date seeds and activated carbon, respectively. In view of the stringent water quality requirements, adsorption using date ...

  • Manure Compost A New Cash Crop

    A growing number of livestock producers are discovering manure compost as a new cash crop. When Mark Meyer refers to the “magic” at New Day Farms, he isn’t referring  to  the  liquid  egg  products  generated  by more than 2.5 million laying hens. Rather, Meyer, the environmental manager  at the Ohio facility, is talking about the ...

  • Dairy manure compost effects on corn silage production and soil properties

    Accumulation of dairy manure compost has created a need to identify alternative uses for this plant nutrient source. This field study determined compost effects on corn (Zea mays L.) silage production, nutritive value, and soil characteristics for three growing seasons following incorporation of dairy manure compost at 0, 35, 70, and 105 Mg dry matter (DM) ha–1. Yields from subplots receiving ...

  • Tourism recreational value of Rock garden, Chandigarh , India

Many of the intangible benefits of such parks/gardens are neither correctly assessed nor incorporated in to benefit-cost analysis of developmental or commercial projects and in budget allocation process, especially in developing countries. Chandigarh, a well-planned and modern city of ...

  • Implementing Research : Georgia Takes Many Routes to Recycle Food Residuals

     PETROLEUM HYDROCARBON LEVELS “One unique local characteristic (and treatment difficulty) we encountered in our composting program,” says Stan Konno, PWC environmental department director head, “is the high level of diesel range total petroleum hydrocarbon (TPH) content in the sludge from the WWTF at Fort Kamehameha.” Oil from past leaks in pipelines and tanks — which go back to 1941 — ...

  • The mineralization of nitrogen from compost in the tropics

    The application of organic matter is very important in maintaining high and stable crop yields under tropical conditions. Most of tropical soils are characterised by low content of organic matter and low structure stability. Animal wastes contain many nutrients, including nitrogen, phosphorous, potassium and other minerals. In addition to supplying nutrients, the application of animal wastes also ...
