Wastewater Treatment
A Ground-Breaking Innovation In Wastewater Treatment
The fashion industry contributes 20% of industrial water pollution With a high water footprint, massive chemical use and atmospheric, water and greenhouse gas (GHG) emissions, dyehouse operations are the most environmentally damaging component of the apparel supply chain2.Global brands are responding by requiring manufacturers to treat wastewater and reduce effluent. Paradoxically, conventional water treatment systems generate toxic sludge, trading water pollution for solid, chemical discharge that is landfilled and emits GHG – mostly methane.

A study on The Removal of Some Phenolic Compounds from Wastewater
ABSTRACT:
The removal by means of Advanced Oxidation Processes (AOPs) is an attractive option for the treatment of industrial wastewater containing phenolic compounds in an environmental . The present work would summarize some AOPs technologies focusing only on heterogeneous catalytic removal of phenol and highlighting the catalysts activity and reaction conditions. The catalysts used were H ZSM-5,H-Mordenite and Bentonite. H-ZSM-5,H-Mordenite doped with Platinum (Pt) were prepared and characterized by using X-ray diffraction analysis (XRD), thermal analysis, Scanning electron microscopy, High Resolution Transmission electron microscopy, pluse titration measurements, nitrogen adsorption desorption at -196°C. the experimental parameters affecting the removal efficiency were time, temperature, pH, initial phenol concentrations, catalyst dose and the effect of irradiating with Ultraviolet (UV –C) were studied . The optimum conditions for the removal of each catalyst were investigated .

Advanced Treatment Technologies For Recycle/Reuse Of Domestic Wastewater
Conventional wastewater treatment technologies improve the quality of wastewater discharged into the environment and restrain polluted waters from contaminating other available clean water resources. However, these treatment technologies do not make wastewater fit for further beneficial uses in communities closer to the points of generation. Innovative and advanced technologies that can further improve the quality of wastewater are needed to overcome this limitation of conventional technologies, and to promote widespread adoption of recycle and reuse practices. Advanced treatment processes can be biological processes, physicochemical processes, or a combination of both (hybrid processes). Biological processes to remove nutrient pollutants such as nitrogen and phosphorus, provide the platform for further wastewater treatment to reusable quality. Physicochemical processes such as deep-bed filtration, floating media filtration, and membrane filtration, play a major role among treatment technologies for water reuse. Membrane filtration has significant advantages over other processes since they produce high quality effluent that requires little or no disinfection with minimum sludge generation. The hybrid processes attempt to obtain the benefits of both biological and physicochemical processes in one step.

Advanced Wastewater Treatment By Nanofiltration And Activated Carbon For High Quality Water Reuse
Hybrid processes combining activated carbon and nanofiltration have been studied to identify the optimum solution for advanced wastewater treatment in high quality water reclamation and reuse. With a focus on the removal of bulk and trace organic compounds the investigation identified three promising process combinations, namely powdered activated carbon followed by nanofiltration (PAC/NF), granular activated carbon followed by nanofiltration (GAC/NF) and nanofiltration followed by granular activated carbon (NF/GAC). The removal potential was examined in lab and pilot scale for a range of refractory pharmaceuticals and industrial chemicals typically detected in effluent in trace concentrations ranging from ng/L to μg/L. Fluorescence excitation emission spectroscopy was employed for the investigation of the fate of effluent organic matter. The optimum strategies for operation of the hybrid processes were determined in pilot scale. The experiments were conducted at the Wastewater Treatment Plant Aachen Soers providing an effluent of high quality with low dissolved organic carbon (DOC) concentrations of about 5 mg/L.
