Treatment of landfill leachate in municipal wastewater treatment plants and impacts on effluent ammonium concentrations.
(Elsevier, 2016-12-05)
Landfill leachate is the result of water percolating through waste deposits that have undergone aerobic and anaerobic microbial decomposition. In recent years, increasingly stringent wastewater discharge requirements have ...
Bioaccumulation of metals in ryegrass (Lolium perenne L.) following the application of lime stabilised, thermally dried and anaerobically digested sewage sludge.
(Elsevier ScienceDirect, 2016-05-09)
The uptake and accumulation of metals in plants is a potential pathway for the transfer of environmental contaminants in the food chain, and poses potential health and environmental risks. In light of increased population ...
The potential for the use of waste products from a variety of sectors in water treatment processes.
(Elsevier ScienceDirect, 2016-07-21)
This review examines the utilisation of waste products from three sectors (industry, agriculture, and construction and demolition) in filters for the removal of contaminants from water. Sand is commonly used in drinking ...
Assessment of intermittently loaded woodchip and sand filters to treat dairy soiled water
(IWA Publishing and Elsevier, 2016-07-31)
Land application of dairy soiled water (DSW) is expensive relative to its nutrient replacement value. The use of aerobic filters is an effective alternative method of treatment and potentially allows the final effluent to ...
Performance and surface clogging in intermittently loaded and slow sand filters containing novel media
(Elsevier ScienceDirect, 2016-05-20)
Slow sand filers are commonly used in water purification processes. However, with the emergence of new contaminants and concern over removing precursors to disinfection by-products, as well as traditional contaminants, ...
Carbon and nitrogen dynamics and greenhouse gas emissions in constructed wetlands treating wastewaters: a review
(2016-02-17)
The removal efficiency of carbon (C) and nitrogen (N) in constructed wetlands (CWs) is very inconsistent and frequently does not reveal whether the removal processes are due to physical attenuation or whether the different ...
Performance of novel media in stratified filters to remove organic carbon from lake water
(IWA Publishing, 2016-08-15)
Disinfection by-products (DBPs) are an ever-increasing occurrence in water networks, particularly those which abstract water from peatland areas. Although much research has been carried out to discover novel methods to ...
Microplastics in sewage sludge: effects of treatment
(American Chemical Society, 2016-12-12)
Waste Water Treatment Plants (WWTPs) are receptors for the cumulative loading of microplastics (MPs) derived from industry, landfill, domestic waste water and storm water. The partitioning of MPs through the settlement ...
A methodological framework to determine optimum durations for the construction of soil water characteristic curves using centrifugation
(De Gruyter Open, 2016-12-30)
During laboratory assessment of the soil water characteristic curve (SWCC), determining equilibrium at various pressures, is challenging. This study establishes a methodological framework to identify appropriate experimental ...
A framework for determining unsaturated zone time lags at catchment scale
(Elsevier Masson, 2016-12-10)
The responses of waterbodies to agricultural programmes of measures are frequently delayed by hydrological time lags through the unsaturated zone and groundwater. Time lag may therefore, impede the achievement of remediation ...
