  • Biodegradation of dairy wastewater using bacterial and fungal local isolates

    Dairy wastewater contains high levels of organics and other pollutants. The present study was carried out to investigate the biodegradation process of dairy effluents using some locally isolated bacteria and fungi. Four different dairy effluent samples were collected from Obour and 6th October industrial cities, Egypt. Five bacterial species (Pseudomonas aeruginosa, Bacillus ...

  • Eco-friendly process combining physical–chemical and biological technics for the fermented dairy products waste pretreatment and reuse

    Residual fermented dairy products resulting from process defects or from expired shelf life products are considered as waste. Thus, dairies wastewater treatment plants (WWTP) suffer high input effluents polluting load. In this study, fermented residuals separation from the plant wastewater is proposed. In the aim to meet the municipal WWTP input limits, a pretreatment combining ...

  • Dairy

    Problem: The Dairy Plant was experiencing difficulties with their waste activated treatment plant due to overloading. Solution: After a very successful trial, the customer installed a Hydrocal CAF to remove as much of the suspended solids, fats, oils and greases (up to 95 - 98%) as necessary to stabilize the biological plant. The CAF 25 and balance ...

  • Electrocoagulation of synthetic dairy wastewater

    This study compares the effectiveness of pollutant removal from synthetic dairy wastewater electrocoagulated by means of aluminum and iron anodic dissolution. A method based on the cubic function (third degree polynomial) was proposed for electrocoagulant dosing. Mathematical methods for calculating the optimal electrocoagulant doses proved to be quite precise and useful for practical ...

  • 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 ...

  • Reuse of dairy lagoon wastewater through SDI in forage crops

    Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of ...

  • Dairy farm New Mexico, USA

    Type of Wastewater System: Facility to Lagoon For Solid and Wastewater Collection Problem: This facility has an expensive liner in its lagoon, and the use of equipment to remove the solids from the lagoon was not an option. It also dewaters the lagoon via irrigation onto row crops every 30 days. The buildup of solids in the lagoon had reached a point of capacity such that they ...

  • 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 ...

  • Digester Developer Taps Natural Gas Markets

    IN the late 1990s, Dan Eastman and two colleagues were researching business opportunities in the renewable energy industry. They were looking for a commercially viable technology that could take renewable energy from an experimental phase to a solid business investment. In 1999, Eastman and his partners founded Microgy, Inc., with its base in Wisconsin. The company licensed the Xergi anaerobic ...

  • Dramatic results in Panama’s Dairy Lagoons

    Nevada Dairy Processor’s wastewater lagoon system had totally failed. Treatment with AquaClean restored the natural condition of the lagoon, with the return of aquatic life and the elimination of odor. AquaClean was able to degrade the heavy loads of fats, oils and grease with on- going ...

  • 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 ...

  • 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 ...


  • To eliminate the disposal of salty whey from a dairy industry into the sewer in an environmental, social and economical way – a case study from dairy farmers, Toowoomba, Queensland, Australia

    The paper is mainly based on the effluent discharged by dairy industries, with a special focus on Dairy Farmers (Toowoomba, Australia) and the problems faced by the industry in discharging the waste. Dairy Farmers, Toowoomba is basically a cheese-manufacturing unit. The major problem with the effluent discharged from the industry is the presence of a high concentration of salty whey. Due to this, ...

  • Enhancement in the Treatment Efficiency and Conversion to Energy of Dairy Wastewaters by Augmenting CST Reactors With Simple Biofilm Support Systems

    Dairy wastewaters are rich in organic carbon and nutrients. When disposed without proper treatment they cause severe pollution of water and land. But if treated by anaerobic fermentation such wastewaters can yield useful clean energy in the form of methane. The systems commonly used for such fermentation throughout the world are Continuously Stirred Tank Reactors (CSTRs). We describe attempts to ...


  • 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 ...
