Spatial distribution and hydrochemistry of springs and seepage springs in the Lubuska Upland of western Poland
The major part of the Polish Plain (central Europe) was shaped during the last glaciation and so far has been considered to be poor in groundwater outflows. The present study aimed to map the groundwater outflows and to analyse their water properties in the Lubuska Upland, western Polish Plain. The mapping of the groundwater outflows was supplemented by hydrochemical analyses (major ions and ...

Short-term temperature impact on simultaneous biological nitrogen-sulphur treatment in EGSB reactor
Sulphides are present in many wastewater streams; their removal is important due to corrosiveness, toxicity and unpleasant odour, and can be carried out by anaerobic biological treatment. This study focuses on the temperature effect (25–10 °C) on an expanded granular sludge bed (EGSB) reactor for sulphide removal using nitrate as electron acceptor. The reactor was run at a NO3−/HS− molar ...

The ion-exchanger–loop-stripping process: ammonium recovery from sludge liquor using NaCl-treated clinoptilolite and simultaneous air stripping
The technical feasibility of an ammonium recovery process (‘ion-exchanger–loop-stripping’) for sludge liquor from municipal wastewater treatment plants is examined. The proposed process combines ion-exchange on natural zeolites with simultaneous air stripping of ammonia to produce an industrial NOx-removal agent. Column experiments with continuously recycled NH4Cl-solutions and a real sludge ...

Characteristics and indications of hydrogen and oxygen isotopes distribution in lake ice body
Stable isotopes have been used to identify the characteristics of precipitation, evaporation, basin hydrology, and residence times. However, lakes in the cold regions are usually covered by ice for 5–6 months. To get a better understanding of stable isotopes characteristics and indications in lake ice bodies, ice and water were sampled during the icebound season in both the ice and water ...

Calibration and Spectrum Troubleshooting
Introduction Airborne molecular contamination, referred to as “AMCs”, is a common cause of defect loss and product degradation in many cleanroom manufacturing environments. Costs associated with AMC-related quality issues and yield losses are well understood, and adequate reduction of AMC is critical for clean manufacturers to stay competitive. For this reason, AMC measurement ...

Comparing electrochemical disinfection with chlorination for inactivation of bacterial spores in drinking water
Drinking water disinfection techniques without the dosage of chemicals are regarded as more advantageous in terms of costs and practical use. Here we investigated the efficacy of electrochemical disinfection for inactivation of Bacillus subtilis spores – a model microorganism of highly resistant pathogens. The effect of electrochemical disinfection with TinO2n−1 ceramic electrodes ...

Determination of ionizing threshold of trimethylamine ions with a high resolution RGA mass spectrometer
In radiation detection, gaseous detectors have an important role in the characterization of incident radiation. Experiences, namely in X-ray spectrometry, X-ray astronomy, medical instrumentation and high energy physics use gaseous detectors, usually with a rare gas, as a detection medium. Recently it was suggested the addition of molecular additives to the main gas to improve some ...

How to Know Which Surface Analysis Instrument to Choose
The features and characteristics of solids are largely dependent on their chemical structure at the surface. Surface analysis is used to determine the chemical structure of the surface number atomic layer (a shallow and thin area of the surface). Surface analysis instruments analyze the elemental composition and chemical state of materials that are present in the surface number atomic layer ...

What Products Can be Used for Plasma Engineering
Plasma is ubiquitous in nature. Plasma is an ionised gas made up of charged particles formed by heating a gas to high temperatures where atoms start colliding, and the electrons are knocked off. Most of the known matter in the universe is in the plasma state. Scientific developments in the field of plasma science have enabled the use of plasma in a wide range of plasma engineering applications ...

How Residual Gas Analysis (RGA) Factors into Leak Detection
Leak detection is an essential aspect of vacuum operations, underlying critical performance indicators like cost, efficiency, and safety. Extraordinary effort has been made to engineer leak-tight systems capable of inducing and maintaining different vacuum regimes without significant loss of pressure due to leaks. Yet no system is perfect. Even the highest-quality chambers, gaskets, pumping ...
