  • 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 ...

  • Beverage Processing (Liquor & Dairy Facilities) - Case Study

    Challenge A dairy beverage company required disinfection of their chilled water and recycled water lines. The water contained high levels of bacteria including pseudonomas aeruginosa and several other bacterial types listed in the water analysis. Solution Genesis Water Technologies consulted with the client and its facilities operations staff on the ...

  • 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 ...

  • Environmental input–output analysis of the New Zealand dairy industry

    This work presents data and analysis quantifying the total (direct and indirect) resource use and outputs (products and pollutants) of the New Zealand dairy industry for the year April 1997 to March 1998. It also identifies those sectors supplying the dairy industry which make significant indirect contributions to its total inputs and outputs. Although this data is 14 years old, it is the only ...

  • 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 ...

  • Composting dairy solids with the ac composter

    In October, ECS began conducting trials at California State University Fresno to explore using the new patent pending AC Composter system to manage dairy manure solids and comply with air-quality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF's research dairy. This research is being conducted with funds from a USDA Small Business Innovative Research ...

  • On the use of non-negative matrix factorisation to characterise wastewater from dairy processing plants

    A portable field spectrometer was used to record the time-resolved ultraviolet/visible (UV/Vis) spectrum of the effluent stream at two different dairy processing plants (a Drier Plant and Cheese Factory). The spectra exhibited significant variability. As an alternative to the partial least squares regression methods usually used in the online UV/Vis field a non-negative matrix factorisation ...

  • Biocontained mortality compost using liquid manure

    During disease outbreaks, composting has been used to safely dispose of carcasses and infectious solid manure. However, optimized methods have not been established to use liquid manure (> 80% water content, WC) from dairies as the substrate for mortality composting. In April of 2007, a 3x2 factorial study was conducted in wooden compost bins (240 x 240 x 140 cm) lined with 0.5 mm plastic to a ...

  • Influence of liquid manure on soil denitrifier abundance, denitrification, and nitrous oxide emissions

    The influence of liquid dairy and swine manure, soil water-extractable C (WEC) and glucose on the amount of denitrification, the N2O molar ratio [N2O/(N2O + N2)], and the abundance of soil denitrifiers was investigated using repacked soil cores. Quantitative polymerase chain reaction was used to measure the abundance of the total bacteria (16S rRNA gene), two denitrifier guilds bearing the cnorB ...

  • Soy Milk Manufacturing

    This facility manufacturer Soy based products to include Soy milk and other dairy substitute products. The facility generates wastewater from their manufacturing operations as well as sanitization. The treatment system includes flow equalization for the 80,000 gallons/day, pH adjustment, and dissolved air flotation. The facility is in compliance with the discharge limits, but still pays over ...

    ' 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. Its mission is to 'supply quality products for safe-guarding the nation’s health' in all its product line. The same attention to quality ...

  • 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 ...

  • CAF Failure: www/RESOURCE DAF Success!

    This dairy manufactures fluid milk, dairy-based mixes, yogurts, and juices. For several years, the facility was using a CAF system to treat its wastewater prior to discharge. The system performed inconsistently and operational costs approached $14/1000 gallons treated. The city could not tolerate the inconsistent performance and the dairy couldnot afford the costs to operate the system. Many ...
