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 ...

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 ...

Chlorine Dioxide gas detection: A comprehensive guide

by Compur Monitors GmbH & Co. KG  (Jan. 22, 2015)

Introduction Some years agoago, the bleaching process in the paper industry was changed from using Chlorine (Cl2) as bleaching agent to Chlorine dioxide (ClO2). This was a challenge forThis posed a major challenge to industrial hygienists, as there were no sensors or detectors available that were specific to Chlorine dioxide: There was no sensor ...

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 ...

Is your Plant as tight as you think? Leak Detector for extremely toxic Gases, a Field Test Report

by Compur Monitors GmbH & Co. KG  (Jan. 22, 2015)

Leak detection of commodity gases in chemical plants is a day-to-day practice. The sensor technology available for this application is field proven and reliable. No question about it, existing sensors will do the job. However, in plants manufacturing or handling extremely toxic substances, the picture is different. For example, take phosgene. The ...

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 ...

Enhanced decomposition of 1,4-dioxane in water by ozonation under alkaline condition

by IWA Publishing  (Dec. 19, 2014)

1,4-Dioxane is a probable human carcinogenic and refractory substance that is widely detected in aquatic environments. Traditional wastewater treatment processes, including activated sludge, cannot remove 1,4-dioxane. Removing 1,4-dioxane with a reaction kinetic constant of 0.32 L/(mol·s) by using ozone, a strong oxidant, is difficult. ...
