“…Faujasite zeolite-based RO membrane rejects more than 95% Cr, and as hydrophilic, it maintains a high flux (Covarrubias et al 2008). A combined adsorption-permeation UF membrane process can also remove Cr from aqueous solution (Pagana et al 2011). Emulsion liquid membrane (ELM) was observed as a very effective process of removing Cr(VI) ions successfully from various aqueous solutions (Saravanan and Begum 2006).…”

Industrial activities that consume water generate wastewater as a by-product of processing which introduces various contaminants such as heavy metals into the neighbouring water bodies that creates adverse effects on the surrounding environment. Tannery industry releases more toxic effluent than most industries, which directly and indirectly exerts stress on various ecosystems. The heavy metal chromium (Cr), one of the pollutants found in tannery effluent, is very much detrimental to human health, animals, and plants. Conventional physico-chemical and biological processes can remove this heavy metal in considerable amounts. Recently, various applications of advanced technologies such as membrane technology, electrocoagulation, ion exchange, and electrodialysis for tannery wastewater have been growing due to their relative advantages over other technologies in terms of sustainability. This paper represents the review of various available techniques as well as represents a case study of chromium removal from tannery effluent by a low-cost absorbent.

“…There are many different methods of separation of chromium from wastewater [3,4,7]. However, traditional methods used for purification of aqueous solutions containing chromium e.g., precipitation method, ion exchange, adsorption, crystallization, or liquid extraction, are often inefficient and expensive, particularly in the case of the purification of the effluent containing very low chromium concentration.…”

This article describes the synthesis of an analcime-C zeolite membrane on a ceramic support by in situ hydrothermal crystallization. A circular shaped ceramic support was firstly fabricated using low cost raw materials by a uni-axial pressing method and sintering process. Subsequently, the zeolite composite membrane was prepared with the repeated coating of analcime-C on the ceramic support through an in situ crystallization technique. The synthesized zeolite composite membrane was characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), porosity, average pore size and pure water permeability. The influence of the number of coatings on the characteristics of the zeolite membrane was also explored. The obtained results clearly demonstrate that the porosity, pore size and water permeability of the membrane decrease significantly with the multiple coating of zeolite over the ceramic support. The porosity, average pore size and pure water permeability of the zeolite membranes are estimated to be 38-24%, 285-155 nm and 2.18 Â 10 À7 to 4.53 Â 10 À8 m 3 m À2 s À1 , respectively for various coatings (1-3). Finally, the separation performance of three times coated zeolite membrane was evaluated by removal of chromium(VI) from aqueous solution by ultrafiltration (UF) at various operating conditions (applied pressure, concentration and pH). The maximum rejection of 84% is achieved at an applied pressure of 207 kPa. Moreover, the separation performance of membrane is better as compared to other membranes reported in the literature.
