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...
متن کاملEnhanced Chromium Recovery from Tannery Waste by Acid-alkali Reaction in China
Leather processing is an important industry in China, and the discharge of chromium waste has been severely circumscribed. Though traditional processes for treating chromium waste have been widely used in tannery plants, technology adopting high efficiency and economic simultaneously is deficient. In order to develop an economic treatment for tannery waste, a mixed alkali of sodium hydroxide an...

متن کاملStudies on Recovery of Chromium Form Tannery Wastewater by 29 Studies on Recovery of Chromium from Tannery Wastewater by Reverse Osmosis
Chromium (Cr) is the most important element used to leather industry is still considered to be the most important industries which pollute the environment by chromium metal. Removal of heavy metals dissolved at low concentrations in water and wastewaters is often a problem that can be solved in different ways. This paper describes a study conducted to determine the recovery of chromium from tan...
متن کاملChromium and phosphorous recovery from polluted water by hydrothermal mineralization
Detoxification of polluted water containing chromium and phosphorous and its resource recovery were investigated by hydrothermal mineralization using Ca(OH)2 or CaCl2 mineralizers. Under the optimum treatment condition for removing chromic acid (at 473 K, for 2 h using CaCl2 mineralizer in an in situ sampling-type autoclave), CrO4 was recovered as CaCrO4 and the concentration in the treated-wat...
