Pharmaceuticals removal in soil following wastewater land application
… One of the most common reuse procedures is land application of wastewater, which follows a wastewater treatment plant or an onsite wastewater treatment system (OWTS). It is not known how well conventional on-site wastewater disposal practices function in removing PPCPs prior to percolation …

Greenhouse and laboratory study for the land application of water treatment residual
… into nearby water courses or dewater them for landfilling. If suitable land is available, land application of residual is cost effective and has the potential for negligible effects on the environment and may prove to be a long-term solution to the disposal problem. This research project …

An experimental study of the environmental impacts of CCA-treated wood waste land application
… waste is disposed of safely in Hazardous Waste Landfills. Despite this, studies have shown that this waste can still enter into the landscape mulch market due to inadequate detection methods and increasing societal pressures to recycle.A series of laboratory and field-based simulations were used …

Extractable organics and colour in a bleached kraft mill effluent land application system and recipient ground waters
… of extractable organics and colour in a land application system used to treat highly coloured, organic-rich, alkali extraction stage and foul condensate effluents from a traditional bleached kraft mill. The land application system comprised 44 unlined seepage basins, totalling 86 ha in …

Evaluation of bacteriophage and viral persistence during alkaline stabilization in sludge and biosolids intended for land application
<p>The use of lime to reduce or eliminate pathogen content is a cost-effective treatment method currently being employed in many Class B biosolids production plants in the United States. A bench scale model of lime stabilization was designed to evaluate pathogen persistence. The survivability of …

A computer simulation model for investigating the effect of land application of sludge on runoff water quality
… which occur in the soil following organic waste applications. CREAMS-NT accounts for nutrient addition through fertilization and rainfall and losses of N by volatilization, denitrification, plant uptake, leaching, and overland flow. Data required by CREAMS-NT includes runoff volume, sediment …

The potential of lime-stabilized and chemically-fixed municipal sewage sludges for land application as lime or nitrogen sources
… to evaluate the effect of increasing sludge application rates on growth of corn. The CCE of the lime-stabilized and chemically-fixed sludges were 30. 9 and 58.1%, respectively. Application of sludges to soils resulted in rapid neutralization of soil acidity. Added organic-N was mineralized at …

Long-term effects of land application of poultry manure on crop production, and soil and water quality under a corn-soybean rotation system in Iowa
… of this eight year study (1998 to 2005) on land application of poultry manure on (i) crop yields and crop quality; (ii) subsurface drain water quality, and (iii) soil quality. Eleven experimental field plots of sizes varying from 0.14 to 0.4 ha were used in this study. Each field plot was …

Effect of land application of fluidized-bed combustion residue on soil and plant characteristics of reclaimed surface-mined pastures, performance and mineral status of grazing steers and nutrient balance by sheep fed the forage
… Mg increased with limestone and S with FBCR application. Cell wall components decreased, while ash and lignin increased with both amendments. Serum mineral levels of cattle were normal except Cu was low. Animal tissues reflected differences in mineral concentration observed in forages. Hay …

Long-term effects of alum sludge application to land
Previous research relating to alum sludge land application has primarily been restricted to laboratory studies of short-term environmental effects. In general, most research has concluded that the environmental effects of alum sludge constituents can be easily controlled. This study investigated …

Advanced aerobic digestion to optimize pathogen reduction: Staged pre-treatment in aerobic digestion
Land application of biosolids is a desirable solution for smaller communities that utilize aerobic digestion. However, traditional aerobic digestion produces Class B biosolids at best which raises public concern regarding the fate of pathogens following land application. The main goal of this work …

A Sustainable Bio-Solids Management For The Grand Forks Wastewater Treatment Plant
… thoroughly for this research, and - on site land application shows some potential. After surveying the Municipal Waste Water Treatment Facilities of the five neighboring states of North Dakota, no specific method was obviously "the strongest solution" for the biosolids' scenario of the …

Effect of Scrubber Sludge and Fly Ash on Soil Properties and Crop Growth
… were conducted to determine the effect of land application of these waste products on soil physical and chemical properties and on corn (Zea mays L.) and soybean (Glycine max (L.) Merr.) growth, nutrient composition, and yield.
-
An assessment of cropland application of alum sludge
Previous research has shown that crop land application of alum sludge can be a valuable method of residuals disposal and has been demonstrated to cause no adverse effects on soil properties and crop yields. Studies have shown that with good soil management practices essential plant macronutrient …

Carbon and nitrogen dynamics on a forest site receiving continual papermill sludge applications: a soil column study
… renovation of wastewater and sludge via land application depends upon sludge-induced soil changes associated with carbon (C) and nitrogen (N) cycles within the soil/plant system. The C, N, and hydrologic cycles within a soil/sludge system receiving a year-round, daily application of paper …

Assessment of sludge management options in a waste water treatment plant
… and incineration, (2) cogeneration and land application, and (3) Composting. Life cycle impacts of global warming potential, eutrophication, acidification, ozone layer depletion potential were calibrated using GaBi.

Evaluation of Macrolide-Lincosamide-Streptogramin B Antimicrobial Resistance at Swine Farms
… field soils and in soil batch tests, since land application of swine manure has also been proposed as a possible factor in the environmental development and dissemination of antimicrobial resistance; the levels of MLSB antimicrobials in field soils amended with swine manure indicated the …

Risk assessment formulation for nitrate leaching
… evaluating the risk of water pollution from the application of liquid dairy manure to agricultural fields was developed and applied. The GLEAMS (Groundwater Loading Effects of Agricultural Management Practices) (Ver 2.1) model was used to simulate NO₃-N leaching below the root zone for different …
