Eco-friendly wet processings of textiles are major concerns of textile producers nowadays to attain high quality products without diversely affecting the environment quality and the enduser health1. Enzymatic processing of textile offers many advantages when compared to traditional chemical methods, namely, enzymes use significantly less water, less energy, and fewer chemicals than traditional ...

The influent type of organic matter (dissolved or particulate) on the characteristics of two subsurface wastewater infiltration systems (SWISs) was investigated. One of the SWISs was fed with dissolved organic matter (glucose, assumed to be readily biodegradable) and the other with particulate organic matter (starch, assumed to be slowly biodegradable). Results showed that both biofilm growth a...

A method to refine corn produces highly pure corn protein isolate (CPI) and intact granular starches (CPI starch). The CPI starch is superior to other commercial starches because of its intact membrane. This paper reports on the effectiveness of the CPI starch in laundering applications by comparison with a commercial starch and polyvinyl alcohol (PVA). Influence of the different starch materia...

There are several contaminants in wastewater, with organic pollutants playing the major role. Many kinds of organic compounds, such as PCBs, pesticides, herbicides, phenols, polycylic aromatic hydrocarbons (PAHs), aliphatic and hetercyclic compounds are included in the wastewater, and industrial and agricultural production as well as the people living could be the source of organic wastewater e...

present study dealt the removal of cr(vi) in a tannery industry wastewater using rice husk silica powder as an adsorbent.the experimental investigations have been carried out by using rice husk silica powder for different adsorption dosage, different contact time and different ph against the initial cr(vi) concentration of 292 mg/l. the maximum percentage removal of cr(vi) in the tannery indust...

Sugar industry is an oldest accommodates industry in the world. It required and discharges a large amount of water for processing. Removal of chemical oxygen demand and color through the electrochemical process including hybrid iron and aluminum electrode was examined for the treatment of cane-based sugar industry wastewater. Most favorable condition at pH 6.5, inter-electrode gap 20 mm, curren...

Potato starch was extruded and roasted with apple distillery wastewater to produce esters substituted malic acid residues. The esterification degree higher at the roasting temperatures. Starch modification contributed its darker color, increased resistance action of amylolytic enzymes, decreased solubility heat phase transition. changes in other properties examined depended on extrusion process...

A wastewater refinery is a multifunctional solution that combines different technologies and processing schemes to recover spectrum of valuable materials from municipal or industrial wastewater. The concept introduces new perspective on treatment management. It aims at making the most constituents by co-producing worthful outputs, such as water, energy, nitrogen, sulfide, phosphorous. This can ...
