  • Principle and Process of Sweet Potato Starch Production

    Sweet potato, also known as sweet potato, sweet potato, hawthorn, red glutinous rice, etc., is an excellent raw material for starch processing. The sweet potato starch production process is actually a physical separation process, which separates the cellulose, protein, inorganic salts and other substances in the raw materials from the starch. In the production process, starch is separated from ...

  • Lowara pumps drive livestock operations

    Animal output processed for safe disposal, reuse and renewable energy Xylem scope Xylem Lowara have installed several different types of pumps in this process cycle. Ranging from the DLV submersible pump fitted with Vortex impeller used in the pressurization of wastewater obtained from the separation of the digestate. Various high efficiency e-range pumps ...

  • Ammonia sanitization of blackwater for safe use as fertilizer

    Source-separated blackwater from low-flush toilets contains plant-available nutrients and can be used as a fertilizer. The aim of the study was to evaluate the impact on pathogen inactivation when treating blackwater with urea and/or lime. Blackwater was spiked with Salmonella typhimurium, Escherichia coli O157, Enterococcus faecalis, and Ascaris ...

  • A Bayesian network model for assessing natural estrogen fate and transport in a swine waste lagoon

    Commercial swine waste lagoons are regarded as a major reservoir of natural estrogens, which have the potential to produce adverse physiological effects on exposed aquatic organisms and wildlife. However, there remains limited understanding of the complex mechanisms of physical, chemical, and biological processes that govern the fate and transport of natural estrogens within an anaerobic swine ...

  • Slurry Lagoon Mountmellick - case study

    Lining Tech have completed lining works to construct a cost efficient 1,000,000 gallon geomembrane lined slurry lagoon in Mountmellick, County Laois. Works included the installation of a 2.5mm smooth HDPE liner in accordance with the Department of agriculture's specification S126 for geomembrane lined slurry lagoon. Works also included the fabrication and sealing of five pipe boot details around ...

  • Survival of Mycobacterium tuberculosis and Mycobacterium bovis in human urine

    Tuberculosis is a zoonotic disease that mainly causes respiratory infection. However, it can also infect other organs such as the kidneys and bladder, which can lead to high counts of the organisms in the urine. Introducing urine diversion systems and reuse of the urine in agriculture may introduce new transmission routes for infection, increasing the risk of spread. This study evaluated the ...

  • Phosphorus distribution in untreated and composted solid fractions from slurry separation

    Received for publication May 7, 2009. The distribution of phosphorus (P) (water-soluble inorganic P [Pi], acid-soluble Pi, and residual P) was determined in 40 samples of solids from solid–liquid separated slurry. These were collected from separation plants using different technologies, separating by simple mechanical means, by flocculation as pre-treatment before mechanical separation or by ...

  • Poultry Food Short

    This facility processes, seasons, cooks, and flash-freezes poultry products and wanted to increase their production. The existing wastewater system could not meet the discharge requirements to the local POTW (city) and more stringent limits were imposed as a condition of their expansion. The facility was looking at a tremendous capital improvement cost to increase the size of their wastewater ...

  • Pilot scale facility to determine gaseous emissions from livestock slurry during storage

    Livestock production is a growing source of air pollution, locally and to the wider environment. Improved livestock manure management has the potential to reduce environmental impacts, but there is a need for methodologies to precisely quantify emissions. This paper describes and evaluates a novel storage facility for livestock slurry consisting of eight 6.5-m3 cylindrical units. The stores may ...

  • Cover crop effects on the fate of N following soil application of swine manure

    Abstract  Cereal grain cover crops increase surface cover, anchor corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] residues, increase infiltration, reduce both rill and interrill erosion, scavenge excess nutrients from the soil, and are easily obtained and inexpensive compared to other cover crop options. The use of cereal grain cover crops in fields where manure application occurs ...
