  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Soil properties and crop yields in response to mixed paper mill sludges, dairy cattle manure, and inorganic fertilizer application

    The contribution of organic wastes to crop yields and soil fertility may be influenced by their composition and the soil type. This 6-yr study (2001–2006) evaluated the effects of repeated additions of mineral fertilizers (MF), mixed paper mill sludges (PMS) (18, 36, and 54 Mg ha–1), dairy cattle manure (DCM) (36 Mg ha–1) alone or with reduced mineral fertilizer (60% NPK) (RMF) and a control, on ...

  • Project aims to produce fertilizer from wastes

    With the highest cattle density in northeastern Wisconsin and urban sprawl sprawling, Brown County has accelerated its investigation into how to handle growing amounts of dairy manure and industrial wastes spread on a diminishing land base.Applying waste on limited crop acreage has led to groundwater contamination issues and pollution problems of lower Green Bay.The solution lies in a value-added ...
