Combine wastewater treatment with biofuel production
Algae Systems LLC (Daphne, Ala.; www.algaesystems.com) has inaugurated a demonstration plant that integrates municipal wastewater treatment with the cultivation of biofuel-producing algae. Pretreated and disinfected municipal wastewater is passed to Algae Systems offshore floating-bag photobioreactors (PBRs), which are located in…
October Chementator Briefs
A step closer to bio-based acrylic acid Last month, BASF SE (Ludwigshafen, Germany; www.basf.com), Cargill (Minneapolis, Minn.; www.cargill.com) and Novozymes (Copenhagen, Denmark; www.novozymes.com) achieved another milestone in the joint development of technologies to produce acrylic acid from renewable resources.…
An energy-saving bioreactor for wastewater treatment
A bioreactor technology for removing organic and inorganic contaminants from industrial wastewater has been commercially launched by developer Honeywell and its subsidiary UOP LLC (Des Plaines, Ill.; www.uop.com). The launch is part of a wider initiative by UOP to respond…
This solar cell promises to be less expensive
A commercial prototype perovskite solar cell that is less expensive than current thin-film solar cells is under development by a team from Nanyang Technological University (Singapore; www.ntu.edu.sg), in collaboration with Dyesol Ltd. (Queanbeyan, NSW, Australia; www.dyesol.com) and professor Michael Grätzel…
Municipal water sludge-optimization technology poised for growth
A sludge-optimization technology for municipal water-treatment facilities is poised for rapid growth after the exclusive worldwide patent-licensing rights for the technology were acquired by CNP Technology Water and Biosolids Corp. (Kenosha, Wisc.; www.cnp-tec.com). The technology, known as AirPrex, was initially…
Mercury removal with modified aluminosilicate clay
The first commercial contract delivery was recently made for an emissions control product that removes mercury from fluegas without the use of activated carbon. The product, known as AS-HgX, is made by Novinda Corp. (Denver, Colo.; www.novinda.com), and will be…
Monitoring pipeline deposits in realtime
The presence of scale depositions in pipelines can restrict flow, limit heat transfer and decrease efficiency. The ability to monitor pipelines for depositions helps avoid issues and optimize costs. The Deposition Watch system from Flowrox Inc. (Linthicum, Md; www.flowrox.us) presents…
Modern Water-Treatment Challenges
Water and wastewater treatment are extremely important at liquefied natural gas (LNG) facilities and other industries that are blossoming due to the shale-gas boom. Engineering concerns are similar to those of other industrial water-treatment and power-generation systems, but with the…
This process realizes large costs savings for manufacturing silicon wafers
Crystal Solar Inc. (Santa Clara, Calif.; www.xstalsolar.com) is preparing for high-volume production of silicon wafers using a process that forms the wafers directly from trichlorosilane (TCS) gas using a chemical vapor deposition (CVD) epitaxy process that can significantly lower the…
Demonstration plants for biomass-to-sugar technology under construction
Edeniq Inc. (Visalia, Calif.; www.edeniq.com) announced progress in building demonstration facilities in Brazil and China that feature the company’s proprietary process for converting cellulosic biomass into industrial sugar for fermentation or catalytic conversion (diagram).
