Behaviours of natural organic matter in membrane filtration for surface water treatment : a review [PDF]

, 2006
Membrane application in surface water treatment provides many advantages over conventional treatment. However, this effort is hampered by the fouling issue, which restricts its widespread application due to increases in hydraulic resistances, operational

The cometary composition of a protoplanetary disk as revealed by complex cyanides

, 2015
Observations of comets and asteroids show that the Solar Nebula that spawned our planetary system was rich in water and organic molecules. Bombardment brought these organics to the young Earth's surface, seeding its early chemistry.

A Combined Mechanochemical and Calcination Route to Mixed Cobalt Oxides for the Selective Catalytic Reduction of Nitrophenols

Molecules, 2019
Para-, or 4-nitrophenol, and related nitroaromatics are broadly used compounds in industrial processes and as a result are among the most common anthropogenic pollutants in aqueous industrial effluent; this requires development of practical remediation ...

Land Use Influence on the Characteristics of Groundwater Inputs to the Great Bay Estuary, New Hampshire [PDF]

, 2004
This research examines the sources and factors affecting nutrient-laden groundwater discharge to the Great Bay Estuary. To further understand this relationship, examination of groundwater residence time, a review of historic land uses, and nitrate source

Modeling the Enceladus plume--plasma interaction

, 2010
We investigate the chemical interaction between Saturn's corotating plasma and Enceladus' volcanic plumes. We evolve plasma as it passes through a prescribed H2O plume using a physical chemistry model adapted for water-group reactions.

The limnological character of bog pools in relation to meteorological and hydrological features [PDF]

Mires and Peat, 2012
As part of a major limnological characterisation of Rancho Hambre mire complex (Tierra del Fuego), five water bodies (bog pools) were sampled between October 2008 and April 2010 and their physico-chemical features studied in relation to meteorological ...

The comparison of water and matter flows in three small catchments in the Šumava Mountains

Soil and Water Research, 2009
The comparisons of water and matter flows have been evaluated in three small catchments with different land uses in the Šumava Mountains in the south-west of the Czech Republic since 1999. The catchment of the Mlýnský stream was artificially drained, the

Peatlands of the Peruvian Puna ecoregion: types, characteristics and disturbance [PDF]

Mires and Peat, 2014
Peatlands represent one of the most important water resources in the Puna grassland ecoregion, but this fact is not yet widely recognised. Puna peatlands also provide key environmental services such as increasing the regional biodiversity of the Andean ...

Molecular Dynamics Insights for Screening the Ability of Polymers to Remove Pesticides from Water

ChemistryOpen, 2019
The use of pesticides in agriculture is known to have environmental impacts, namely it leads to underground and spring water contamination. Thus, it turns out that nowadays general‐endeavor towards the sustainability of farmer production requires novel ...

Age and Land Use as Factors Differentiating Hydrochemistry and Plant Cover of Astatic Ponds in Post-Agricultural Landscape

Journal of Water and Land Development, 2014
Small, astatic ponds are important features of post-glacial landscape, which support heterogeneity and biodiversity of agricultural areas. In the presented research we explored differences in hydrochemistry and plant cover of 20 small ponds located in ...
