  • 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 ...

  • 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 ...

Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...

I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...
