This study investigated the treatment of dairy wastewater using electrocoagulation method with iron filings as electrodes. The dealt real samples collected from local factory for products in Baghdad. Response Surface Methodology (RSM) was used to optimize five experimental variables at six levels each variable, estimating chemical oxygen demand (COD) removal efficiency. These were distance betw...

Dairy wastewater (DWW) contains large amounts of mineral and organic compounds, which can accumulate in soil water causing serious environmental pollution. A constructed wetland (CW) is a sustainable technology for the treatment DWW small-medium sized farms. This paper reports two-year study on performance pilot-scale horizontal subsurface flow system Sicily (Italy). The CW covered total surfac...

Waste is a natural and unavoidable component of all processes, it can be caused by number things, including resource utilisation, process inefficiencies, the removal less usable feedstock components. Due to growing worldwide population, dairy sector expanding producing waste such wastewater (from cleaning, processing, maintenance), whey, sludge. These elements are nutrient-rich contain both org...

Erratum: “Radionuclides in Fracking Wastewater: Managing a Toxic Blend” The Focus article “Radionuclides in Fracking Wastewater: Managing a Toxic Blend” [Environ Health Perspect 122:A50–A55 (2014); http://dx.doi.org/10.1289/ehp.122-A50] incorrectly stated that Pennsylvania requires pit liners for temporary impoundments and disposal to have a minimum thickness of 30 mm. The correct minimum thick...
