Maintaining neutral pH in deep soils and ground water utilizing insoluble colloidal buffers

by Remediation and Natural Attenuation Services, Inc. (RNAS)  (Nov. 10, 2014)

ABSTRACT: Optimal pH for most biodegradation processes falls between 6.5 and 8.5. Enhanced bioremediation in poorly buffered soils and ground water is likely to lower pH below 6.5 as the added electron donor produces carbon dioxide and or ganic acids. The common agricultural practice of liming soils adds alkalinity and adjusts soil pH by mixing ...

From Wastewater Treatment to Sweet Pineapples

by Sulzer Ltd  (Nov. 5, 2014)

In wastewater treatment, ammonia that is removed from sewage used to be discharged directly to the atmosphere. Nowadays, studies have identified that ammonia emissions are of major concern to air quality. This has led to a new way of thinking.

Catching air - Jimmy Gasore is working on Africa’s first high-frequency climate observatory in his native Rwanda.

by MIT - Massachusetts Institute of Technology  (Oct. 30, 2014)

Original story at MIT News All around the planet, high-frequency climate observatories are collecting atmospheric data around the clock as part of the Advanced Global Atmospheric Gases Experiment (AGAGE), a 35-year-old project to study emissions and climate change. But there’s one problem: Despite a network of ...

Hunters Point Case Study (In Situ Gas Thermal Remediation (GTR™))

by GEO Inc  (Oct. 29, 2014)

In Situ Thermal Remediation with Gas Thermal Remediation (GTR©) is being used to remove NAPL contaminants from a former military base. The system is extracting 378 liters (100 gallons) of liquid waste every week. LNAPLs, such as fuel and oils, and DNAPLs, such as PCBs and chlorinated solvents, are being removed from the subsurface to make way ...

Approximated EU GHG inventory: proxy GHG estimates for 2013

by European Environment Agency (EEA)  (Oct. 28, 2014)

Objective of the report This report provides estimates of greenhouse gas (GHG) emissions in the European Union (EU) and its Member States for the year 2013, covering the full GHG inventory (all sectors, except land use, land‑use change and forestry (LULUCF), and all gases). These estimates are also referred to as approximated ('proxy') ...

Compliance Issues Facing Midstream Production - Case Study

by Catalytic Products International (CPI)  (Oct. 27, 2014)

It’s in the news every day; the natural gas production industry is experiencing record growth.
