  • Design of an integrated piggery system with recycled water, biomass production and water purification by vermiculture, macrophyte ponds and constructed wetlands

    Since 2001 the swine experimental station of Guernévez has studied biological treatment plants for nutrient recovery and water recycling, suited to the fresh liquid manure coming out of flushing systems. An integrated system with continuous recycling was set up in 2007, associated with a piggery of 30 pregnant sows. It includes a screen, a vermifilter, and macrophyte ponds alternating with ...

  • Management of waste organic matters and residential used water for culture and biomass production of red worm (Tubifex tubifex)

    The efficacy of red worm (Tubifex tubifex) for converting organic wastes like pig dung, poultry excreta and dairy sludge into worm biomass production was investigated. For this purpose, three experiments each for pig dung, poultry excreta and dairy sludge were conducted in cement trenches for 90 days duration. The poultry excreta produced maximum biomass (126.53 ± 2.16 g), followed by the ...

  • Adsorptive removal of trace oxytetracycline from water by acid-modified zeolite: influencing factors

    Because of the wide use of antibiotics in the livestock industry, trace tetracycline antibiotics are frequently detected in swine wastewater and water bodies near pig farms. Based on natural zeolite, modified zeolite was synthesized by treatment with nitric acid. As one kind of typical tetracyclines, oxytetracycline (OTC) was chosen as the target adsorbate. Removal of trace OTC by modified ...

  • Transport and fate of estrogenic hormones in slurry-treated soil monoliths

    Received for publication October 29, 2007. The naturally occurring hormones, such as 17-β-estradiol, 17-{alpha}-estradiol, and estrone, present in livestock manure may have detrimental environmental effects if released into surface waters. In areas where manure application is intensive, estrogens have been found in surface waters in concentrations known to affect the endocrine system of fish ...

  • Long Lake Colony Case Study

    Long Lake Colony Farm is an 1,800-head swine operation located in Wetonka, South Dakota that uses a 25,000 gallon per day capacity well-water system. Preliminary testing of the system showed elevated bacteria levels in the farm’s water. The water quality also contributed to clogged water lines in the animal drinking system. The bacteria and water line issues resulted in strep problems in ...

  • 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, ...

  • Taenia eggs in a stabilization pond system with poor hydraulics: concern for human cysticercosis?

    The objective of this study is to compare the removal of Taenia eggs to the removal of Ascaris eggs in a wastewater stabilization pond system consisting of three ponds in series, where the hydraulic residence time distribution has been characterized via a tracer study supported by computational fluid dynamics modeling. Despite a theoretical hydraulic retention time of 30 ...

  • Worming the way to finished compost

    SCREENING AND GRINDING When materials from CR&R and other generators are unloaded, a preliminary screening separates out nonorganic contaminants.    Even though there are source separated programs in places like Temecula and Lake Elsinore, there is the occasional appearance of plastic and glass that needs to be sorted out. Next, Bodlak’s crews put materials through a Vermeer tub ...

  • Sunset Colony Study

    “We have had the Silver Bullet AG300 unit now for ten months with great measurable results. This system is currently on our water line, treating the swine gestation, farrowing and nursery. The unit can treat 75,000 gallons of water per day and will be injected into our large water tank to treat our swine gestation, farrowing, nursery, finishers and dairy. What I like about the Silver Bullet ...

  • Using full-scale duckweed ponds as the finish stage for swine waste treatment with a focus on organic matter degradation

    The rapid increase in the number of swine has caused pronounced environmental impacts worldwide, especially on water resources. As an aggregate, smallholdings have an important role in South American pork production, contributing to the net diffusion of pollution. Thus, duckweed ponds have been successfully used for swine waste polishing, mainly for nutrient removal. Few studies have been ...
