A Study on removal of chromium from tannery effluent treatment of chrome tanning waste water using tannery solid waste

This study illustrates the process of removal of chromium from chrome tanning waste-water by fly ash which was drive from chrome shaving dust. This experiment was carried out in a batch process with laboratory prepared adsorbent samples and chrome tanning water collected from local tanneries. The influence of various factors likes adsorbent doses, contact time, and initial concentration of chro...

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 ...

Hazardous solid waste from domestic wastewater treatment plants.

The treatment of liquid wastes in municipal sewage treatment plants creates significant quantities of solid residue for disposal. The potential hazard from these wastes requires that their characteristics be determined accurately to develop environmentally sound management criteria. It is readily recognized that the sludge characteristics vary with the type and degree of industrial activity wit...
