Institutional and Other Small Water Treatment Plants to Meet Unusual Conditions

Differential expression of microRNAs and other small RNAs in barley between water and drought conditions

Drought is a major constraint to crop production, and microRNAs (miRNAs) play an important role in plant drought tolerance. Analysis of miRNAs and other classes of small RNAs (sRNAs) in barley grown under water and drought conditions reveals that drought selectively regulates expression of miRNAs and other classes of sRNAs. Low-expressed miRNAs and all repeat-associated siRNAs (rasiRNAs) tended...

Polyhydroxyalkanoate Production on Waste Water Treatment Plants: Process Scheme, Operating Conditions and Potential Analysis for German and European Municipal Waste Water Treatment Plants

This work describes the production of polyhydroxyalkanoates (PHA) as a side stream process on a municipal waste water treatment plant (WWTP) and a subsequent analysis of the production potential in Germany and the European Union (EU). Therefore, tests with different types of sludge from a WWTP were investigated regarding their volatile fatty acids (VFA) production-potential. Afterwards, primary...

“ New challenges for small wastewater treatment plants ”

INTRODUCTION Safe wastewater treatment methods have always been a challenge to the society. During the last 50 years, pollution abatement measures have been given high priority, particularly discharges from the growing urban areas. Early objectives were to reduce the emissions of organic matter and pathogens, while other objectives related to the emission of heavy metals and nutrients (phosphor...
