The intermittency of renewable energy technologies requires adequate storage technologies. Hydrogen systems consisting of electrolysers, storage tanks, and fuel cells can be implemented as well as batteries. The requirements of the hydrogen purification unit is missing from literature. We measured the …

Problems of energy security, diversification of energy sources, and improvement of technologies (including alternatives) for obtaining motor fuels have become a priority of science and practice today. Many scientists devote their scientific research to the problems of obtaining effective brands of alternative …

Industrial, agricultural, and domestic sectors have an impact on the pollution of surface waters. More specifically, discharges of wastewater treatment plants also have a major impact on the quality of surface waters. According to PBL Netherlands Environmental Assessment Agency, Dutch surface waters …

Calcium phosphate and struvite crystallization has been widely studied for phosphate removal and recovery from urban wastewater. In this study, calcium phosphate and struvite crystallization were carried out in a fluidized-bed reactor. Experimental values of the P concentration ranged from 117-1000 mg …

INAUGURAL LECTURE The world is in disarray. Species are extinct, climates are changing, we are becoming unhealthier. To liberate ourselves from this doom scenario we need to take care of ourselves and our environment. The solutions of former generations offer no future solace. Moreover, these caused …

Eutrophication because of heightened phosphorus and nitrogen input into freshwater ecosystems is an increasing problem, while at the same time phosphorus availability for agricultural purposes is decreasing on a high pace. B-Ware Research Centre and Radboud University Nijmegen developed a novel biocascade …

With increasing world population, more wastewater is produced which all need purification treatment. Removal of pathogenic organisms is important because they can cause problems to human health. This experiment will focus on the removal of human bacterial pathogens. The problem of human bacterial pathogens …

In this study we tested 39 Lactococcus lactis strains isolated from diverse habitats for their robustness under heat and oxidative stress, demonstrating high diversity in survival (up to 4 log units). Strains with an L. lactis subsp. lactis phenotype generally displayed more-robust phenotypes than strains …

The invention relates to an improved process for the purification of lactide from a crude lactide vapour product comprising at least lactide, lactic acid, water and linear lactic acid oligomers.

The inventation relates to a process for the purification of lactide from a crude lactide vapour product stream which process comprises a rectification/condensation step to a lactide-enriched condensate.
