  • 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., ...

  • 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 ...


  • Asian dairy churns out grade AA effluent

    ' The AIRE-O2® aerators have excellent oxygen transfer, easy maintenance and operation.' Problem Founded in 1937, this dairy cooperative located in Asia has played a leading role in the development of the industry in its country.

  • 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 ...

  • 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 ...

  • 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 ...

  • EDTA in the environment: with special reference to the dairy industry

    Ethylenediaminetetraacetic (EDTA) acid has been used as an additive to caustic agents facilitating removal of Ca, Mg and trace metals in dairy processing plants for many years. Effluents from the dairy industry are either discharged to surface waters or used in land irrigation systems. In particular, the effluents from a large dairy factory discharged to a small stream have the potential to pose ...

  • CH#829 - Municipal Treatment and Dairy Waste

    Background The treatment plant at this midwest city is a well operated facility treating approximately 1 mgd municipal waste from the surrounding community and a high grease load from a local dairy. Over the past several years the publicly owned treatment works has had difficulty producing an excellent quality effluent with respect to BOD 5, and suspended solids. To achieve this level of ...

  • 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 ...

  • 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 ...

  • 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 ...
