“…The presence of dyes makes wastewater treatment difficult for the traditional techniques. The removal of dyes by physical (Golob et al 2005), chemical (Rajkumar and Kim 2006) and even biological (Zheng and Liu 2006) means is widely reported. Such techniques are incapable of causing complete degradation, and this can generate toxic by-products; some dyes are resistant to biodegradation, for example, because of their biotoxicity coupled with a possible mutagenic and carcinogenic effect (Gong et al 2008).…”

The laboratory tests for the use of sapogenic amphiphilic glycosides as a coagulation-flocculation aid are presented in this paper. These amphiphilic glycosides were obtained, through a natural fermentation process, of the juice, of fique (Furcraea sp.) leaves. Decantation allows for the separation of a supernatant denominated ''supernatant fique juice'' and a decanted fraction denominated ''decanted fique juice.'' The latter contains most of the sapogenic amphiphilic glycosides and was mixed with the chemical coagulant ferric chloride hexahydrate, at varying doses. Ferric chloride hexahydrate was also used as a control to ascertain the removal efficiency of persistent contaminants from samples of a textile industry effluent. The parameters of interest were typical indicators of water quality such as color, turbidity, chemical oxygen demand, pH and conductivity. The results indicate that the decanted fique juice, when used as a coagulationflocculation aid, and upon comparison with the chemical coagulant alone, causes an additional color and turbidity reduction of 31 and 17 %, respectively. No significant differences were noted in the chemical oxygen demand values (a = 0.05; P \ 0.001). Thus, there is a scope for further research about the commercial feasibility of DFJ as an industrial water treatment agent, which reduces the toxicity of raw fique juice and its detrimental environmental effects.

“…The treatment efficiencies of COD and the dye between aerobic and anoxic MBR were compared. A laboratory-scale membrane bioreactor (MBR) witha gravity drain was tested [42] for dyeing and printing wastewater treatment from a wool mill. Results showed that excellent effluent quality could meet the reuse water standard in China.…”

This study demonstrated the importance, process, activation and applications of Membrane in bioreactor to treat the waste water. Membrane Bioreactor (MBR) process consists of a biological reactor integrated with membranes that combine clarification and filtration of an activated sludge process into a simplified, single step process. Operating as an MBR allows conventional activated sludge plants to become single step processes, which produce high quality effluent potentially suitable for reuse. Application of MBR technology for industrial wastewater treatment has also gained attention because of the robustness of the process. Theoretically, maintenance of long SRT in MBR is in favor of the retention and development of special microorganisms, which may lead to better removal of refractory organic matter and make the system more robust to load variations and toxic shocks. Literature suggested the conceptual expectation of enhanced biodegradation of hardly biodegradable compounds in MBR does not often come true. Improved biodegradation to certain extent has been reported in a few studies; however the underlying factors leading to such improvement still remains to be elucidated. This is comprehensive review of the studies dealing with recalcitrant industrial wastewater treatment by MBR, and casts light on the strategies to achieve enhanced biodegradation of hardly biodegradable industrial pollutants in MBR.
