Enhanced Sludge Reduction Using External Bioaugmentation at a Full-Scale Municipal

Shcici R., Newbold A., In-Pipe Technology Company, Inc., US

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 [...]

Comparative Analysis of the Glendale Advanced Wastewater Treatment Plant in Lakeland, FL Using Bioaugmentation

Schici R., In-Pipe Technology Company, Inc., US

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 [...]

Optimizing the removal of Heavy Metals of an artificial wastewater by electrocoagulation using response surface methodology

Suárez A., Agudelo N., Universidad Libre, CO

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. [...]

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 [...]

Removal of Selenium from Aqueous Solutions Using Magnetite Nanoparticles as Adsorbent

Wei X., Bhojappa S., Lin L.-S., Viadero R.C., SUNY Institute of Technology, US

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 [...]

Increasing the Efficiency of Photocatalytic Water Treatment with Titanium Dioxide Nanoparticles by Control of Crystal Shape

Rickerby D., European Commission Joint Research Centre, IT

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 [...]

Innovative Technology for Selective Contaminant Removal

Lean M.H., Chang N., Seo J., Kole A., Hsieh H.B., Melde K., PARC, US

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 [...]

The Intersection Between Water Scarcity and Renewable Energy

Muys Jr. J.C., Karp J.M., Hildebrand Jr. V.P., Sullivan & Worcester LLP, US

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 [...]

The Effects of Bioaugmentation in Collection System

Newbold A., Dickerson R., Kelter M., In-Pipe Technology, US

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 [...]

Effects of membrane pore morphology on fouling behavior of polymeric micro-fabricated membrane during crossflow micro-filtration

Warkiani M.E., Gong H.Q., Fane A.G., Wicaksana F., Nanyang Technological University, SG

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 [...]
