DOI 10 22161/ijeab/2 6 10 Keyword Tannery Wastewater Scoria Filter Media Removal efficiency Wastewater parameters Abstract In present study Scoria a volcanic ash identified as potentially efficient low-cost and locally available filter media as an adsorbent for the treatment of tannery wastewater and investigated as a filter media for tannery wastewater treatment with selected

Biological Wastewater Treatment This article briefly discusses the differences between aerobic and anaerobic biological treatment processes and subsequently focuses on select aerobic biological treatment processes/ technologies By Arun Mittal Aerobic Anaerobic Before we go in to the discussions of various aerobic biological treatment processes it is important to briefly discuss the

Siraj et al investigated the removal of chromium from tannery effluent using chitosan-charcoal composite[6] The composite was prepared by simple solution evaporation method To know the chromium removal capacity of charcoal chitosan and the composite known amount (20 g/l) of chitosan activate charcoal and composite were added to 10 ppm of chromium solution in three different

Biological treatment of tannery wastewater by using salt

The non-sterilized tannery saline wastewater samples were taken separately and the efficiency of COD removal by isolated salt tolerant bacterial strains was studied by inoculating them as pure monocultures Samples were also run with mixed isolated salt tolerant bacterial consortia and tannery activated sludge Blank runs were made with natural organisms present in raw tannery saline

removal efficiency of BB7 was found to be of the dye concentration upto 600 ppm by using 10 mg (0 1g/L) adsorbent MGO at pH~7 within 6 minutes The MGO material was very effective to remove BB7 and it might be used for the treatment of organic dye containing tannery wastewater Keywords

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product After treatment the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment Most industries produce some wastewater Recent trends have been to minimize such production or

Wastewater by Precipitation with Due Consideration to Cost Optimization" Journal of Environmental Research and Develeopment vol 2(2) pp 209-216 2007 [2] A Esmaeili A Mesdaghi nia and R Vazirinejad "Chromium (III) Removal and Recovery from Tannery Wastewater by Precipitation Process" American Journal of

In the present study the treatment of tannery wastewater was performed by electrocoagulation method (EC) using aluminium and steel electrodes Response surface methodology (RSM) with three factors current density (I) electrolysis time (t) and pH with each factor at five levels was used to optimize the factors for higher chemical oxygen demand (COD) and total suspended solids (TSS) removal

Using Scenedesmus sp for the Phycoremediation of

This study evaluates the growth of the microalga Scenedesmus sp in three different concentrations of wastewater (20% 50% and ) at a tannery in Bogot Colombia for a period of 15 days and assesses the removal of chromium nutrients and organic load Results indicate a growth proportional to the concentration of the effluent with greater biomass in undiluted wastewater Likewise

The effect of pH on turbidity removal from jar tests for coagulation of tannery wastewater is shown in Fig 1 Figs 2 3 and 4 show the effect of coagulant addition on the reduction of COD color and chromium at the optimum coagulation pH for each coagulant (pH

The results indicate to that the removal was effective at low Cr(111) concentrations and low pH value and the optimum conditions for chromium tanning removal operation wastewater investigated were 60 minutes and 1200 rpm as a contact time and agitation rate respectively and pH value equals to 0 5 at the temperature 252*C And adsorbent dose 16 g/L was sufficient for the high removal of Cr

The result also shows that removal efficiencies of COD NH4-N and TKN were as high as 91% 98% and 89 35 % at the cycle time of 24hrs The 24hr cycle length with 12hr aerobic and 8hr anoxic conditions were selected as the optimum working conditions for enhanced removal of nutrient from tannery wastewater using SBR Low COD and nitrogen removal

Removal of toxic Cr(VI) ions from tannery industrial

In this research the wastewater samples were collected from leather tanning industry at different time intervals The parameters like pH electrical conductivity temperature turbidity chromium and chemical oxygen demand (COD) of the samples were analyzed A three-phase three-dimensional fluidized type electrode reactor (FTER) was newly designed for the effective removal of toxic pollutants

In this study spent tea leaves a valueless waste produced during the manufacturing of tea beverage were assessed for their potential to remove chromium (Cr) from tannery wastewater Cr removal was studied by the batch process with varying adsorbent dose contact time and pH of the solution to finding optimum conditions The experiment results showed that maximum removal of Cr by spent tea
