Treatment Systems For Sulfate Removal in Water and Wastewater (yasa.ltd) Sulfate in water can be harmful for humans and must be removed from effluents in industrial applications by using the correct water treatment systems before disposal. ...

Liquid effluent produced from tanning industries is loaded with organic and inorganic contaminants, particularly heavy metals, which may cause severe damage to the ecosystem. ...
For comparison, the plants were also grown on both synthetic solution and tannery effluent with known concentration of 0.1, 0.5 and 1 mg/L Cr3+ at Bahir Dar tannery. ...
We evaluate the applicability of a reverse osmosis (RO) system that combines powdered activated carbon (PAC) and ultrafiltration (UF) to treat the effluent discharged from tannery wastewater treatment plants. Conventional treatment processes such as neutralization, clariflocculation, and biological processes are used to clean the effluent ...
In this study, we analysed the genotoxic and cytotoxic effects of treated tannery wastewater using the micronucleus (MN) test in fish erythrocytes (Bryconamericus iheringii) and the Allium cepa test system. Fish were exposed to three different concentrations of tannery effluent (2, 5 and 10%) for 3 and 6 days. Onion bulbs were exposed to four ...
Treatment of a dyeing bath of a tannery was carried out using a hybrid membrane-based separation scheme consisting of Nanofiltration (NF) followed by Reverse Osmosis (RO). ...
This paper reports on findings of a study on the performance of two units of a Horizontal Sub-Surface Flow Constructed Wetland (HSSFCW) units in treating wastewater effluent from a tannery industry. One of the HSSFCW units was planted with macrophytes, while the other was used as a control (without plants). ...
This paper reports a study of batch extraction of trivalent chromium from dilute aqueous solutions as well as electroplating and tannery effluent by Emulsion Liquid Membrane (ELM) technique. An experimental study was performed to optimise the pH of the aqueous external phase based on distribution coefficient of solute between aqueous external phase and organic ...
Cake filtration model is described to establish/quantify transient flux decline mechanism for membrane separation of tanning effluent collected from tannery. Two membrane operations, Nanofiltration (NF) followed by Reverse Osmosis (RO), are adopted to treat tanning effluent. ...
This paper reviews the major biological treatment methods applied for tannery effluents in India. Anaerobic methods and activated sludge process have been the preferred treatment options. Sequencing batch reactor process holds promise for tannery effluents but the technology is yet to see the light of the day in India. ...
Al2 (SO4)3, 18H2O, FeCl3 and Ca (OH)2 were used for the treatment of tannery wastewaters. The influences of pH and coagulant dosages were studied. Conditions were optimised according to the pollutant removal efficiencies, the volume of decanted sludge and the biodegradability index improvement. The results indicate that 67-71% of total COD, 76-92% of color and 79-97% of chromium can be removed ...
The system was installed within the premises of the Common Effluent Treatment Plant (CETP), which receives effluents from nearly 200 tanneries. ...
