Ideally, pressure driven membrane processes used in wastewater treatment such as reverse
osmosis and nanofiltration should provide a complete physical barrier to the passage of …

This study presents the use of dry bean pods as a solid phase for fluorescein removal from
water. The non-pretreated solid phase did not display any sorption properties for the chosen …

Background. Ultrasonic scaling generates aerosols and splatters contaminated with
microorganisms, increasing the risk of disease transmission in the dental office. The present …

The stability of a rock slope is strongly influenced by the pattern of groundwater flow through
the fracture system, which may lead to an increase in the water pressure in partly open joints …

For several pilot-scale constructed wetlands (CWs: a planted and unplanted gravel filter)
and a hydroponic plant root mat (operating at two water levels), used for treating …

Much debate has occurred in catchment hydrology regarding the connectivity of flow paths
from upslope areas to catchment outlets. This study was conducted in two catchments, one …

The capability of five fluorescent dyes to serve as conservative tracers in highly saline
groundwater was evaluated by a series of batch experiments on pure minerals and natural …

UV-vis absorption, steady state fluorescence emission, time-correlated single photon
counting and laser flash photolysis methods were employed to examine the excited state …

Rainfall-runoff response in temperate humid headwater catchments is mainly controlled by
hydrological processes at the hillslope scale. Applied tracer experiments with fluorescent …

This paper presents a revision of the history, definitions, and classification of tracers (natural
and artificial, internal and external). The fundamental ideas concerning tracers are …
