“…PES is hydrophobic in nature and is prone to fouling, but owing to its resilience, it finds application in various industries. 6 The present study focuses on harvesting of microalgae using fouling resistant polyether sulfone (PES) mixed matrix membranes (MMMs). The antifouling property of MMMs has been significantly improved by modifying the membrane surface using hydrophilic nanomaterials.…”

BACKGROUND Extracellular polymeric substances and microalgae stimulate membrane fouling during harvesting. The objective of the study was to compare the effect of pore formers on TiO2 embedded polyethersulfone mixed matrix membranes (MMMs) to harvest Coelastrella sp. FI69. The study experimented with hydrophilic additive (polyethylene glycol), polyelectrolyte additive (polyethylenimine), inorganic additive (zinc chloride) and charged polymer (sulfonated polyetherether ketone (SPEEK)) as pore formers. RESULTS It was found that SPEEK/TiO2 combination enhanced the hydrophilic property of the PES membrane surface. Also, contact angle value (55.22°) was decreased by 1.38 times that of a neat PES (76.63°) membrane. Morphology studies indicated that the TiO2 particles dispersed well in the PES membrane matrix along with pore formers. The existence of super hydrophilic TiO2 supported the restriction of microalgae cell attachment on the membrane surface. The filtration of alginic acid sodium solution analysis showed that PES/SPEEK/TiO2 and PES/PEG/TiO2 membranes support higher flux with minimal fouling percentage. Microalgae filtration studies indicated that synergistic effect of both SPEEK and TiO2 on PES membrane exhibited higher water recovery percentage of 96% and equilibrium flux of 66 L m‐2 h‐1. CONCLUSION Fouling propensity is significantly reduced in modified membranes. Future research on scale‐up of membranes for further microalgae dewatering applications is recommended. © 2017 Society of Chemical Industry

The textile dyeing industry is one of the hazardous polluting industries which uses water as the major source for their production and substantially the generation of wastewater leads to be a huge burden in treatment. The existing treatment methods adopted in most of the dyeing industries are said to be very old and its efficiency of removal is very less and at the same time it does not meet the standards for trade effluent discharge as prescribed by the regulatory boards. The study carried out on the application of Activated Carbon Filter (ACF) outlet in three stages of Reverse Osmosis results in reduction of 52% and the Total Dissolved Solids (TDS) is reduced to 226 ppm under the operation time of 10 hours. Significance reduction in pH, BOD, COD, TSS and Sulphates. The results say that the new technology of applying Nano-filtration and ultra-filtration will increase the efficiency of treatment. The effluent characteristics with the help this technology satisfy the standards.

“…Traditional physical treatment can be used to treat wastewater effluent, with methods such as adsorption using activated carbon [5], ultrafiltration [6], ion exchange [7], and coagulation [8]. However, these treatments just transfer the pollutant to another phase, hence a further handling is needed.…”

Catalytic Degradation of Textile Wastewater Effluent by Peroxide Oxidation Assisted by UV Light Irradiation

Textile industries produce a complex wastewater which is difficult to be treated. In this work, a catalytic degradation of wastewater effluent composed of sulphur black coloring agent discharged by industry was studied. UV lamp power, peroxide concentration, pH, and iron oxide catalyst were varied to determine the best conditions for oxidative treatment. Kinetic parameters were evaluated based on the reaction model proposed. In the absence of iron oxide catalyst, chemical oxygen demand (COD) and biological oxygen demand (BOD) degradation of up to 80% and 75%, respectively, were observed as resulting from using an H 2 O 2 concentration of 0.61 moles/L, UV lamp power of 30 watts, and pH of 6. When using an iron oxide catalyst combined with UV light irradiation, the degradation rate could be increased significantly, while similar final COD and BOD degradation percentages resulted. It is found that the reaction rate order was shifted from first order to second order when using an H 2 O 2 /UV/Fe 2 O 3 system. The results could be an alternative for treating textile industry wastewater, and the parameters obtained can be used for equipment scale-up.
