Microwave assisted synthesis of CaO nanoparticles and use in waste water treatment
Clean water (i.e., water that is free of toxic chemicals and pathogens) is essential to human health. Advances in nanoscale science and engineering are providing unprecedented opportunities to develop more cost effective and environmentally acceptable [...]
Effects of membrane pore morphology on fouling behavior of polymeric micro-fabricated membrane during crossflow micro-filtration
Membrane pore morphology can have a significant effect on the rate of flux decline where the dominant fouling mechanism is pore blockage and cake formation. Commercial micro-filters cannot be used effectively for this purpose because [...]
The Effects of Bioaugmentation in Collection System
The wastewater treatment plant in the Town of Orange Park, Florida was challenged to meet a new discharge permit issued by the Basin Management Action Plant (BMAP) for the lower St. John’s River that was [...]
The Intersection Between Water Scarcity and Renewable Energy
The starting point for any discussion of the intersection between water scarcity and renewable energy is the now generally-accepted correlation between climate change and water resource impacts, which is creating further imperatives for both reduction [...]
Innovative Technology for Selective Contaminant Removal
This paper describes a two-stage water treatment technology for removal of dissolved contaminants that is relevant to many water matrices. Removal is achieved by adapting conventional adsorption, coagulation and flocculation, or lime softening and/or soda [...]
Increasing the Efficiency of Photocatalytic Water Treatment with Titanium Dioxide Nanoparticles by Control of Crystal Shape
The most commonly employed photocatalytic material is titanium dioxide; anatase is the photocatalytically reactive phase. Highly dispersed anatase nanoparticles have a large specific surface area. However the reaction is inherently inefficient because only a very [...]
Removal of Selenium from Aqueous Solutions Using Magnetite Nanoparticles as Adsorbent
Selenium (Se) is an emerging contaminant for many regions worldwide especially for areas impacted by past or current mining activities. The objective of this study was to evaluate the effectiveness of synthesized magnetite nanoparticles as [...]
Heavy Metal Removal from Aqueous Solution using Agricultural Waste
Bansala M., Singhb D., Aggarwalc S., Gargd V.K., Giani Zail Singh College of Engineering & Technology, IN
Biosorption has gained important credibility during recent years because of its ecofriendly nature, excellent performance, and low cost domestic technique for remediation even heavily metal loaded waste water. The potential of cheap cellulose containing natural [...]
Optimizing the removal of Heavy Metals of an artificial wastewater by electrocoagulation using response surface methodology
The Response Surface Methodology (RSM) was employed to investigate the effects of pH and current density on the removal of cadmium, copper and zinc in a artificial wastewater with a large COD by electrocoagulation technique. [...]
Comparative Analysis of the Glendale Advanced Wastewater Treatment Plant in Lakeland, FL Using Bioaugmentation
The City of Lakeland, Florida selected bioaugmentation in 2001 to treat odor and corrosion in a partial section of the collection system. The technology was in place within the sewer system for approximately six months [...]
Enhanced Sludge Reduction Using External Bioaugmentation at a Full-Scale Municipal
One the biggest burdens facing municipal wastewater treatment plants are the expenses of hauling and disposing of residual biosolids, or sludge. In 2007, United States municipal wastewater treatment plants produced about 7.7 million dry tons [...]
Effects of calcination conditions and Fe/Al molar ratio on structure and properties of mixed Fe/Al-PILCs
Zheng H., Weidler P.G., Pu Y., Cai P., Wu Y., School of Materials Science and Technology, China University of Geosciences, CN
In this paper, solutions containing hydroxyl-FeAl oligocations with Fe/Al molar ratio of 0.5 and 1.0 were prepared by adding Na2CO3 solution to mixture of FeCl3 and AlCl3 with constant stirring until a final OH/(Al+Fe) ratio [...]
Efficiency of Point-of-Use Water Disinfection Using Deep UV Light Emitting Diode Technology
Gaska I., Gaska R., Bilenko O., Bilenko Y., Shturm I., Bilenko O., Bilenko Y., Shatalov M., Gaska I., Gaska R., Sensor Electronic Technology, Inc., US
We present results of microbial disinfection of E.coli bacteria in water using Point-of-Use UV light-emitting diode (LED) chamber. A set of four UVCLEAN LED lamps was used to produce UV radiation at 272-273nm. More than [...]
