  • EDTA in environments subjected to disposal of dairy effluent from processing plants

    The presence of Ethylenediaminetetraacetic acid (EDTA) in environments related to the disposal of dairy effluent has been investigated. An HPLC–UV analytical method was used to determine concentrations of EDTA in soil, surface and ground waters. Method detection limits were 1.5 mg/kg (dry weight) for soil, 1 μg/L for surface water and 2 μg/L for groundwater. A quasi one–dimensional vertical ...

  • Dairy Products

    Problem: This dairy located in Northern California is a major supplier of consumer milk products. The plant had been discharging their wastewater to the local sanitation plant untreated. Due to industrial growth in the area, the sanitation plant could no longer accept the dairy effluent. The dairy, therefore, selected and installed a Sequential Batch Reactor (SBR) system to treat their ...

  • EDTA in dairy wastewater and removal efficiency - a case study

    EDTA is the most widely used chelating agent for removal of undesirable cations in many industrial applications such as the dairy industry. It is generally considered to be non–biodegradable by conventional wastewater treatment, thereby potentially producing an environmental health risk. Under suitable conditions, however, EDTA has been reported to be effectively degraded by micro organisms ...

  • CH#736 - Dairy Waste with Oil and Grease

    300,000 GPD of dairy waste water with oil and grease content of 50-320 mg/l lead to excessive scum formation and elevated T.S.S. in effluent. It was decided to try BIO-SYSTEMS B220RED F.O.G. reducing bugs to reduce influent oil and grease loadings. Application rate was 15 lbs. per day to pump station dedicated to the dairy. Results were quick ...

  • 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 ...

  • Nitrogen losses from dairy manure estimated through nitrogen mass balance and chemical markers

    Received for publication February 13, 2009. Ammonia is an important air and water pollutant, but the spatial variation in its concentrations presents technical difficulties in accurate determination of ammonia emissions from animal feeding operations. The objectives of this study were to investigate the relationship between ammonia volatilization and 15N of dairy manure and the feasibility of ...

  • Molecular epidemiology of campylobacter jejuni populations in dairy cattle, wildlife, and the environment in a farmland area

    We describe a cross-sectional study of the molecular epidemiology of Campylobacter jejuni in a dairy farmland environment, with the aim of elucidating the dynamics of horizontal transmission of C. jejuni genotypes among sources in the area. A collection of 327 C. jejuni isolates from cattle, wildlife, and environmental sources in a 100-km2 area ...

  • Plan B 3.0 -- A Plan of Hope

    Plan B is shaped by what is needed to save civilization, not by what may currently be considered politically feasible. Plan B does not fit within a particular discipline, sector, or set of assumptions. Implementing Plan B means undertaking several actions simultaneously, including eradicating poverty, stabilizing population, and restoring the earth’s natural systems. It also involves cutting ...

  • Another www/RESOURCE (DAF) Success in a DAIRY

    The dairy manufactures ice cream, fluid milk and other dairy products. Escalating sewer surcharges of over $30,000/month were a concern. World Water Works installed the www/RESOURCE Dissolved Air Flotation system to pre-treat the wastewater. Since startup, the facility has reduced its wastewater costs by over $15,000/month. This figure includes the cost of operating the system. The project ...

  • A Study on Assessment on Pollution Load from Dairy Effluent

    ABSTRACTBiodegradation is increasingly being considered as a less expensive alternative to physical and chemical means of decomposing organic pollutants. Pathways of biodegradation have been characterized for a number of microorganisms, some of which have been used for remediation of water. Because algae are photoautotrophic their use for bioremediation of surface waters would circumvent the ...


  • 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 ...

  • Microbiologically influenced corrosion in dairy effluent

    Abstract: In the dairy industry mild steel is used as the construction material for the effluent treatment plants, pipelines, reinforcement in concrete structures etc. The steel exposed to the dairy effluent faces corrosion due to the microbes. In the present study the role of microbes in dairy effluent on the corrosion of mild steel has been investigated. Pseudomonas sp., Streptococcus sp., ...
