Improving Dairy Wastewater
Dairy Wastewater Treatment The typical dairy wastewater treatment system has a “separator” screen that removes about 10-15% of the larger solids from the flush water. The solids are returned as bedding for the cows, and the dairy waste water liquid flows to the first pond. Typically, there are a series of ponds, which rely on anaerobic (without oxygen) digestion to degrade ...

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 ...

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 Subsurface Drip ...

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 ...

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 ...

Case Study: Dairy Plant minimizes product loss with online COD, cream and protein monitoring
Reducing product loss and limiting COD discharge to the municipal sewer system were key goals for a dairy manufacturing plant. The facility looked to Real Tech to help achieve these goals, installing an industrial grade, real-time BOD/COD probe on the effluent of their production plant. The wastewater probe delivered reliable and continuous COD, cream and protein data, in addition to event ...

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 ...

Statistical modelling of the impact of some polyphenols on the efficiency of anaerobic digestion and the co-digestion of the wine distillery wastewater with dairy cattle manure and cheese whey
The objective of this study was to determine the effectiveness of anaerobic digestion in the treatment of polyphenols (PP) present in olive mill wastewater (OMW) and wine distillery wastewater (WDW). Anaerobic Toxicity Assay (ATA) was conducted to assess the impact of the most representative phenolic compounds present in OMW and WDW: catechol, tannins and p-Coumaric acid, on biogas production. ...

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 ...

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 ...
