Spolchemie site remediation and NanoRem field site application

by NANO IRON s.r.o.  (Jan. 26, 2015)

Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of ...

Gordy Pump Station - St. Mary Parish Gordy, LA case study

by Propex Operating Company, LLC  (Sep. 23, 2014)

The first levee armoring project designed by the New Orleans District of the Corp of Engineers (COE) post Hurricane Katrina utilized Armor-Max®, an Anchored Reinforced Vegetation System. It was installed in December 2006 on the land side of the levee to prevent erosion from overtopping. ArmorMax® is a combination of a high performance turf ...

Fuzzy maximum power extraction control for a photovoltaic water pumping system

by Inderscience Publishers  (Dec. 17, 2014)

AC loads present a delicate matter for photovoltaic systems, and this is because of the photovoltaic panel's operating point, which moves randomly according to irradiance changes; in this case, almost of photovoltaic water pumping systems use a DC–DC converter to ensure either the maximum power extracted from PV panel or the load needs. For AC ...

Detailed dynamic pumping energy models for optimization and control of wastewater applications

by IWA Publishing  (Sep. 30, 2014)

Despite the increasing level of detail in wastewater treatment process models, oversimplified energy consumption models (i.e. constant ‘average’ power consumption) are being used in optimization exercises. A new dynamic model for a more accurate prediction of pumping costs in wastewater treatment has been developed to overcome this ...

Deep soil mixing shoring system to construct a 60 MGD, 40 foot deep wastewater pumping station

by Geo-Con, Inc.  (Mar. 25, 2014)

The City of San Mateo, CA operates three wastewater pumping stations on a 80' wide lot located in a residential area near San Francisco Bay. The age of the stations range from 12 to 50 years, the stations have difficulty pumping peak wet weather flows, and have structural and maintenance problems. For these reasons, a new station was proposed to ...

Energy Efficient Vertical Turbine Pumps Promote Sustainable Mining Efforts

by Neptuno Fluid Technology Lid  (Sep. 1, 2014)

The computational fluid dynamics process advances highly efficient pump designs for difficult applications. Energy is a strategic input for the mining industry in Latin America and worldwide. Mining requires large amounts of energy, which drives up total operational costs. In Chile, mining companies consume 34 percent of the total energy produced ...
