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 ...

Rapid small-scale column testing of granular activated carbon for organic micro-pollutant removal in treated domestic wastewater

by IWA Publishing  (Oct. 20, 2014)

This study investigates the applicability of the rapid small-scale column test (RSSCT) concept for testing of granular activated carbon (GAC) for organic micro-pollutants (OMPs) removal from wastewater treatment plant (WWTP) effluent. The chosen experimental setup was checked using pure water, WWTP effluent, different GAC products, and variable ...

Collaboration essential for an energy neutral urban water cycle

by IWA Publishing  (May 16, 2013)

Two Dutch water boards prepared a Master Plan with measures to substantially reduce their energy use by 2027. In total, more than 100 measures were identified such as bubble aeration and heat recovery from effluent. Together these measures result in a 90–95% reduction in energy use at the water boards. However, for the whole urban ...

by Rainwater Harvesting Limited  (Sep. 4, 2012)

Carbon Neutral Cottage in Suffolk. Little Cottage in Wickham Market is a great example of what carbon neutral homes of the future may look like and they estimate the 120 sq.m property could cost as little as £340 a year for heating, hot water and lighting. The Site Little Cottage in Wickham Market is a great example of what carbon neutral ...

Copenhagen aspires to be the first carbon neutral capital in the world

by Worldwatch Institute  (Jun. 13, 2012)

The City Council of Copenhagen is aiming to make the capital carbon neutral by 2025 – the first capital city in the world to do so. CO2 emissions have already been reduced by 21 % since 2005. On the 23rd of August, 2012, it is expected that a majority of votes at the Copenhagen City Council will pass the CPH 2025 Climate Plan with the ...

Egyptian explorer Omar Samra, 33, has returned to Dubai to calculate his CO2 emissions in order to offset any environmental damage caused by his successful summiting of 16,050ft Mount Vinson, Antarctica’s highest mountain. Through a sponsorship partnership with Dubai-based Carbon Credit brokerage, Advanced Global Trading (AGT), Samra will ...

Application Note: Wastewater Neutralization Process Using the Sievers InnovOx TOC Analyzer

by GE Analytical Instruments  (Jan. 2, 2013)

Industrial wastewater is a result of manufacturing, agricultural, environmental, and research activities. Managing the treatment and discharge of industrial effluents is a critical process that ensures compliance with regulatory ordinances, upholds public health and safety, and guarantees the protection of natural and public resources. Classical ...

An innovative hydrodynamic separation technology (HDS) for water pretreatment: harvesting neutrally buoyant particles effectively

by IWA Publishing  (Apr. 3, 2013)

This paper describes the feasibility and application of a fluidic-based technology, called hydrodynamic separation (HDS), to separate suspended particles from liquid. It uses customized fluid flow patterns in a curved channel to create a pair of Dean vortexes that focus particles into a concentrated band near one channel wall. A splitter at the ...

Carbon footprints of Scandinavian wastewater treatment plants

by IWA Publishing  (Aug. 29, 2013)

This study estimates the carbon footprints of 16 municipal wastewater treatment plants (WWTPs), all situated in Scandinavian countries, by using a simple model. The carbon footprint calculations were based on operational data, literature emission factors (efs) and measurements of greenhouse gas emissions at some of the studied WWTPs. No carbon ...
