  • Anaerobic Digestion at Dairy Farms

    The need to upgrade dairy waste management practices to overcome pollution problems is leading more farmers to seek solutions with anaerobic digestion technology. Two recent examples of this trend are underway at California sites. The Cal Poly Dairy is located adjacent to the California Polytechnic State University campus in San Luis Obispo. The dairy milks 180 cows with a total population of ...

  • Farm digesters for small dairies in Vermont

    THROUGH its award-winning Cow Power program, Central Vermont Public Service (CVPS), a Vermont utility headquartered in the city of Rutland, is helping dairy farmers diversify their incomes by turning manure into electricity. The farmers process manure in anaerobic digesters to generate power, which CVPS customers voluntarily pay a premium to purchase. In addition to income from electricity sales, ...

  • Himmerland dairy farm case study

    A. PRE-TREATMENT Barn Type: 60 tie stall dairy barn. Mats used in stalls. Manure Handling: Barn houses about 17 – 20 cows along each of two 120 foot parallel pits 2.5 feet wide and 5 to 9 feet deep (stepped). The pits gravity drain to the center of the pit and then flow out to an outside manure storage pit via 2.5 foot square pipe. Half of south gutter is used to handle parlour wash. ...

  • Confidential Client, Dairy Farm, Pennslyvania - Case Study

    In July 2011, AdEdge Water Technologies was selected by CET Engineering Services and the client via a competitive bidding process to design, manufacture, and commission a packaged nitrate removal system for a food processing plant in Pennslyvania. The existing water system is a 0.7 MGD system consisting of a single well pump feeding multiple atmospheric storage tanks coupled with final UV ...

  • Dairy Processor- Wilcox Farms, Salem OR, USA

    The dairy processor manufactures a wide variety of products for the local market. This long established community based business prides itself in good management, manufacturing and citizenship. But when the city wastewater treatment surcharges for TSS and BOD passed $20,000 per month to greater than $30,000 per month, in less than a year, action became necessary. The dairy had been contacted by ...

  • Dairy Digester Opens Doors On Maryland Farm

    Kilby Inc., a 600-cow dairy operation located in Colora, Maryland, has the only operational commercial anaerobic digestion (AD) system in the state. In 2009, Kilby Inc. (the dairy farm and milk production business) began construction of a covered lagoon digester, which started operating in March 2011. The digester input consists of flushed cow manure (98% by volume) and food waste (2%), including ...

  • Linking Wisconsin dairy and grain farms via manure transfer for corn production

    One relatively under-used manure management strategy employed by dairy farmers is to transport and apply manure onto the fields of nearby grain farmers. While this system offers advantages to both parties, little of the existing research on manure management has been conducted on grain farms. As part of an effort to link grain and livestock farms in southern Wisconsin, 20 on-farm trials were ...

  • Application of artificial neural network to model the energy output of dairy farms in Iran

    An artificial neural network (ANN) model was developed to assess the energy input–output prediction in dairy farms of Iran. Data used were culled from 50 randomly selected farms using face to face questionnaire approach. The energy input–output analysis was carried out for the parameters of ANN model. Based on performance measures, single hidden layers with 16 neurons in the hidden ...

  • Maintenance strategies for on-site water disinfection by ultraviolet lamps on dairy farms

    Bacteria have been detected in many water supplies on dairy farms, and the water used to wash milking equipment should be free of bacteria. This study evaluated two ultraviolet (UV) technologies, with and without automatic sleeve cleaning device, as on-farm water disinfection system. No fouling was observed during 6 months of continuous operation of the self-cleaning UV system. The dose provided ...

  • Operationalising eco-efficiency in agriculture: the example of specialised dairy farms in Flanders

    Eco-efficiencies of a representative set of Flemish dairy farms were determined for the years 19891990 and 20002001. Eco-efficiency was measured as a combination of nitrogen (N) use efficiency and energy use efficiency, where N use efficiency (l milk kg-1 N surplus) is the ratio between the amount of produced milk and the farm-gate N surplus (= N input − N output). Energy use efficiency (l milk ...

  • Valtra and Kesla are a perfect combination for forestry work

    Valtra and Kesla are an ideal pairing for forest tasks. Customers have used Valtra-Kesla combinations for years, of course, but now the two companies are also teaming up in product development and the sales network. For example, in Finland and some other markets Valtra and Kesla products can be purchased from the same dealer. The Unlimited Studio at the Valtra factory in Suolahti has also ...

  • Florida Dairy Succeeds With AD System

    North Florida dairy with 6,100 mature cows and 5,500 replacements installed anaerobic digestion system that is yielding multiple benefits. Dairy farming in Florida has financial and logistical challenges, including hot, humid summers; high electrical costs; access to fresh water; odor; greenhouse emissions and sandy soil issues. Alliance Dairies in Trenton, Florida has found sustainable ...

  • Treatment of farm dairy effluent with hybrid upflow multilayer bioreactor and activated sludge module

    Biological removal of nitrogen and carbon from farm dairy effluent (FDE) was studied with two laboratory-scale systems following nitrification and denitrification processes. Each system consisted of an upflow multilayer bioreactor (UMBR) as a pre-denitrification unit, an aeration tank (AT) as nitrification unit and a secondary clarifier. The optimization of two operational variables, total ...

  • Molecular characterization of giardia isolates from calves and humans in a region in which dairy farming has recently intensified

    Giardiasis is a notifiable disease of high prevalence in New Zealand, but there is limited knowledge about the sources of Giardia duodenalis genotypes that can potentially cause human infections. Dairy calves are one environmental source of Giardia isolates, but it is unknown whether they harbor genotypes that are potentially capable of causing ...

  • Californias Dairies have more anaerobic funds

    Producers must be able to sell excess electricity and have markets for that power if projects are to be viable, says the CEO of Western United Resource Development. APPLICATIONS are now available for funding construction of anaerobic digestion systems on California dairies. The California Energy Commission has funds of $2.3 million provided through the Dairy Power Production Program (DPPP). To ...
