HKU team develops new wastewater treatment process

(The University of Hong Kong) A University of Hong Kong research team has developed a novel wastewater treatment system that can effectively remove conventional pollutants, and recover valuable resources such as phosphorus and organic materials. This novel system combines chemically enhanced primary sedimentation of sewage with acidogenic fermentation of sludge in tandem, can effectively remove trace emerging chemical contaminants from wastewater and is more cost effective compared with conventional wastewater treatment systems.

Coral tells own tale about El Niño’s past

(Rice University) Rice University and Georgia Tech scientists use data from ancient coral to build a record of temperatures in the tropical Pacific Ocean over the last millennium. The data question previous links between volcanic eruptions and El Niño events.

Samara Polytech scientist designs wind-powered generator

(Samara Polytech (Samara State Technical University)) Post-graduate student of Samara Polytech is designing an induction for the renewable energy installations. The unique device allows increasing the efficiency and quality of the wind turbine.

Under extreme heat and drought, trees hardly benefit from an increased CO2 level

(Karlsruher Institut für Technologie (KIT) ) The increase in the CO2 concentration of the atmosphere does not compensate the negative effect of greenhouse gas-induced climate change on trees: The more extreme drought and heat become, the less do trees profit from the increased supply with carbon dioxide in terms of carbon metabolism and water use efficiency. This finding was obtained by researchers of Karlsruhe Institute of Technology (KIT) when studying Aleppo pines. Their study is reported in New Phytologist (DOI: 10.1111/nph.16471).

Assessing the global problem of poor sanitation

Experts are investigating a better way of measuring the number of people exposed to the health risks of poorly-managed sanitation systems – and it will help reveal whether the world is on track to deliver UN Sustainable Goal 6 (SDG6).

From greenhouse gas to a high-tech resource

(Karlsruher Institut für Technologie (KIT) ) At Karlsruhe Institute of Technology (KIT), the NECOC research project is aimed at building a unique test facility for active reduction of atmospheric carbon dioxide. The worlds first container-scale facility of this type is to convert CO2 contained in ambient air into highly pure carbon black powder that can be used as a resource in industry. Project partners are INERATEC GmbH, a spinoff of KIT, and Climeworks, a spinoff of ETH Zurich.
