Dye Waste Treatment

Dye wastes represent one of the most problematic groups of pollutants because they can be easily identified by the human eye and are not easily biodegradable. This literature review paper highlights and provides an overview of dye waste treatments performed over the three years period from 2008–2010. Noteworthy processes for the treatment of dye waste include biological treatment, catalytic oxi...

Anaerobic Waste Treatment Fundamentals

Anaerobic filters (AFs) and upflow anaerobic sludge blanket (UASB) reactors are finding wide-scale acceptance for treating various types of wastewater. They are frequently used for medium to high strength wastewater (2,000 to 20,000 mg/L COD), but have fewer applications to low strength wastewater (< 1,000 mg/L COD). In order to understand the applicability of anaerobic treatment for low streng...

Drilling Waste Treatment

Contamination types, levels and their behavior within drilling wastes is determined by the local geological conditions and drilling mud design; notably lubrication fluids, weighting agents and anti-foaming agents. Such additives can contain potentially toxic elements such as aluminum and barium. Besides being contaminated, drilling wastes often have a high pH due to the addition of lime, causti...

Treatment of Textile Waste Water with Organoclay

In this study a sample of bentonite obtained from Semnan mines, was modified by a surfactant to prepare an organoclay with high surface area. BET analysis showed that the modification increased its surface significantly. The prepared sorbent was used for removal of dyes and other organic pollutants from a waste water obtained from Ekbatan textile company. Adsorption was studied in ...
