Introduction There is growing environmental concern regarding the health impact of trace levels of pharmaceuticals and personal care products (PPCPs) in the environment. PPCPs and endocrine disrupting chemicals (EDCs) detected in surface and drinking waters, as well as in treated wastewater, are an issue of increasing international attention due to potential environmental impacts.1,2 These comp...

The 1977 Clean Water Amendments to Public Law 92-500 were enacted to ~strengthen the ori@nalpolicy of encouraging the utilization ofinnovative, alternative management techniques far the treatment and disposal of municipal wastewater. These alternative techniquesinclude spmy krigation and overland flow land treatment systems which can be used individual& cr combined with lagoons. The lagoons ser...

Low efficiency of conventional aeration techniques and the excessive production and disposal of sludge are great concerns in biological wastewater treatment systems. The present study aimed to evaluate the active sludge method using batch reactors under continuous operation to determine the efficiency of aeration and sludge production through microbubble and nanobubble aeration. The results ind...

Minimal liquid discharge (MLD) in greenhouses minimizes the volume of discharged wastewater, thereby increasing effluent that may be reused. Sodium accumulation wastewater is often considered main bottleneck to achieving 100% reuse. Consequently, have begun adopting reverse osmosis (RO), most commonly used desalination technology for treatment. RO removes ions from indiscriminately, including m...

Rural areas represent approximately 95% of the 14000 km(2) Alabama Black Belt, an area of widespread Vertisols dominated by clayey, smectitic, shrink-swell soils. These soils are unsuitable for conventional onsite wastewater treatment systems (OWTS) which are nevertheless widely used in this region. In order to provide an alternative wastewater dosing system, an experimental field moisture cont...

The treatment of textile wastewater for reuse using an electrochemical oxidation step combined with a membrane filtration step is reported in this paper. The electrolytical process is a traditional one, which is easy to scale up and to apply in practice. This paper proposes a modification of the transfer-flow membrane (TFM) module with fibres welded in an arc-shape to enhance the mechanical pro...

OBJECTIVE Environmental estrogens at an elevated concentration are known to produce adverse effects on human and animal life. However, the majority of researches have been focused on industrial discharges, while the impact of livestock wastes as a source of endocrine disrupters in aquatic environments has been rarely elucidated. In order to investigate the contribution of environmental estrogen...

The land disposal of waste and wastewater is a major source of N2O emission. This is due to the presence of high concentrations of nitrogen (N) and carbon in the waste. Abattoir wastewater contains 186 mg/L of N and 30.4 mg/L of P. The equivalent of 3 kg of abattoir wastewater-irrigated soil was sieved and taken in a 4-L plastic container. Abattoir wastewater was used for irrigating the plants ...

W hen the U.S. finally gets serious about climate change, it will have to reduce emissions of CO 2 by more than a factor of two during this century in order to do its part in stabilizing atmospheric concentrations (1). CO 2 capture and disposal is among the most important supply-side technologies for managing the carbon problem. This technology could enable continued access to fossil energy whi...
