  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 an Arthrospira platensis with digested piggery wastewater

    An Arthrospira platensis strain ZJWST-S1 was isolated in Jiaxing City, China, which proved able to proliferate quickly in undiluted digested piggery wastewater (DPW), and the protein content in the algal biomass was high. Single factor experiments showed that the strain was able to quickly grow in a Zarrouk medium as the dosage of sodium bicarbonate, nitrate-nitrogen and phosphate-phosphorus ...

  • Fate of indicator microorganisms under nutrient management plan conditions

    Nutrient management plans (NMPs) for application of wastewater from concentrated animal feeding operations are designed to meet crop water and nutrient requirements, but implicitly assume that pathogenic microorganisms in the wastewater will be retained and die-off in the root zone. A NMP was implemented on a field plot to test this assumption by monitoring the fate of several fecal indicator ...

  • 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 ...

  • New study finds recycled phosphorus could fertilize 100 percent of U.S. corn

    The world has a problem. A phosphorus problem. Needed to fertilize crops, the bulk of phosphorus comes from nonrenewable phosphate rock. While China mines the most — producing almost half the world’s phosphorus — Morocco alone controls three-fourths of global phosphate rock reserves. Year by year those global reserves ...
