  • Electrochemical oxidation of tetracycline antibiotics using a Ti/IrO2 anode for wastewater treatment of animal husbandry

    In animal husbandry, antibiotics are widely used to treat and prevent diseases or to promote growth. The use of antibiotics for domestic animals enables to promote safety of livestock products and enhance productivity. Tetracycline antibiotics (TCs) are one of the primarily used groups of antibiotics for cattle and swine. However, the unintentional spreading of antibiotics from animal waste to ...

  • Cultivation of rice for animal feed with circulated irrigation of treated municipal wastewater for enhanced nitrogen removal: comparison of cultivation systems feeding irrigation water upward and downward

    To achieve enhanced nitrogen removal, we modified a cultivation system with circulated irrigation of treated municipal wastewater by using rice for animal feed instead of human consumption. The performance of this modified system was evaluated through a bench-scale experiment by comparing the direction of circulated irrigation (i.e. passing through paddy soil upward and downward). The modified ...

  • 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 ...

  • Occurrence of tylosin in swine wastewater in Mexico

    This study determined a tylosin concentration in swine wastewater located in a Mexican pig farm, during different stages of the pigs' growth. The detection of antibiotics in swine wastewater is complex due to its high concentration of solids. Analytical method was developed for detection of tylosin in swine wastewater and swine slurry. Average recoveries of tylosin in the liquid and solid ...

  • Pesticide destruction in agrochemical wastewater with DiaCell® - Technology

    Chemicals commonly called pesticides (herbicides, insecticides) are extensively used in farming to increase yields and protect crops. These products are very efficient but they are also very toxic. Pesticides may have ecological effects or be toxic for various terrestrial and aquatic animals and plants. These effects may be due both to the pesticide itself as well as its breakdown products. The ...


  • The viability of treated piggery wastewater for reuse in agricultural irrigation

    Background The swine production is a very important economic matter, occupying prominent position in the worldwide market. However, it appears as the greater impacting activity for the water resources. Researches point a swine manure production of 105.6 million m3/year in Brazil, which resulted in a piggery wastewater rich in solids, nutrients, heavy metals, and pathogens. Moreover, ...

  • Reuse of dairy lagoon wastewater through SDI in forage crops

    Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of ...

  • Nitrogen removal and power generation from treated municipal wastewater by its circulated irrigation for resource-saving rice cultivation

    This study aims at improving the performance of the cultivating system of rice for animal feed with circulated irrigation of treated municipal wastewater by applying a larger amount of wastewater, as well as adding a microbial fuel cell (MFC) to the system. The results of bench-scale experiments indicate that this modification has increased the rice yield, achieving the target for the rice ...

  • CAFO Manure Treatment-Struvite Removal and Struvite Prevention

    CAFOs (Confined Animal Feeding Operations) face struvite in their manure holding ponds and manure lagoons, as well as their recirculation systems. On a dairy farm in Neb. that operated with 15,000 milking cows, they were generating 500,000 gal per day of wastewater laden with manure.  Over the summer, they noticed a reduction in their pumping capacity because the first lagoon was ...

  • Experience in improving fertiliser value of compost by enriching with urine

    Urine contains a lot of nitrogen, phosphorus and potassium, and could act as valuable plant fertiliser. But urine is often either flushed down a toilet or enters a pit latrine, thus being lost to agriculture and increasing surface and groundwater contamination with nitrogen. Ecological sanitation concepts are closing the loop of nutrients contained in wastewater with agriculture. Besides ...

  • Hog facility Texas, USA

    Type of Wastewater System: Supernate pit flush system Problem: This facility was having problems with manure crusting and floating on the top of the pit. This was making it impossible to flush the solids from the pit to an anaerobic digester. It was also having a tremendous buildup of ammonia gas that was causing irritation to the pigs and the employees. Flies were beginning to ...

  • Application of mussels as biosamplers for characterization of faecal pollution in coastal recreational waters

    Sources of faecal pollution in coastal recreational waters may be identified by analysing different host associated microorganisms or molecular markers. However, the microbial targets are often present at low numbers in moderately impacted waters, and often exhibit significant temporal and spatial variability in waters with fluctuating faecal loads. This patchy occurrence can limit successful ...

  • Agrior Project, Chaudière-Appalaches, Quebec, Canada

    Compost Drying Application Agrior makes high value organic fertilizers by composting a mixture of animal manure and organic municipal and industrial wastewater treatment sludge. A DRY-REX low-temperature drying system was designed and installed at Agrior’s facility to dry the mixture into high-quality compost. The low-temperature process results in the drying of the manure with minimal ...

  • Independent review of retrofitting Cambi to mad

    ABSTRACT Denmark has taken a very positive view of recovering energy from organic wastes by anaerobic digestion (AD) and then using  the digestate (digested material) on land. Substituting CHP (combined heat and power) from AD for fossil energy is part of  the national energy plan. Co-digestion of manure, putrescible waste and biosolids is becoming increasingly common. Part of  ...

  • Airborne endotoxin concentrations at a large open-lot dairy in Southern Idaho

    Endotoxins are derived from gram-negative bacteria and are a potential respiratory health risk for animals and humans. To determine the potential for endotoxin transport from a large open-lot dairy, total airborne endotoxin concentrations were determined at an upwind location (background) and five downwind locations on three separate days. The downwind locations were situated at of the edge of ...
