- Abstract:
- ... Screening whole effluent toxicity tests are cost/effective methods for detecting the presence of toxic concentrations of unknown pollutants, but the application must solve the problem associated with the effect of high and variable concentrations of nutrients in the effluent on the results of algal toxicity tests. This work proposes a cost/effective test, based on three dilution levels measured at ...

- Abstract:
- ... The 137Cs and 210Pb dating of a 61-cm long sediment core retrieved from a drinking water reservoir (Lake Brêt) located in Switzerland revealed a linear and relatively high sedimentation rate (∼1cmyear−1) over the last decades. The continuous centimeter scale measurement of physical (porewater and granulometry), organic (Corg, P, N, HI and OI indexes) and mineral (Cmin and lithogenic trace elements ...

- Abstract:
- ... The option of reusing greywater is proving to be increasingly attractive to address the water shortage issue in many arid and semiarid countries. Greywater represents a constant resource, since an approximately constant amount of greywater is generated from kitchen, laundries, bathroom in every household daily, independent of the weather. However, the use of greywater for irrigation in particular ...

Intensive and semi-intensive sea cucumber aquaculture produces effluents that impact the quality of the local aquatic environment and sea cucumber growth; such effluents are an important cause of coastal water eutrophication. Integrated aquaculture has been shown to efficiently reduce the release of nutrients during aquaculture and to provide economic benefits. In this study, we report our investi ...

To avoid the negative impacts associated to the discharge of wastes into water courses, effective remediation processes are required to reduce nitrogen and phosphorus concentrations in discharged effluents.

The average nitrogen (N), phosphorus (P) and organic matter (OM) concentrations in the filling-up water of the fishponds were 2.51 ± 1.25, 0.57 ± 0.57 and 23.8 ± 13.4 mg l⁻¹, respectively. Contrarily, the N, P and OM con ...

- Abstract:
- ... The results of three Partial Least Squares (PLS) regression models were used to gain a holistic view on the consequences of natural processes and anthropogenic pressures for water quality degradation and biodiversity decline in a multi-use watershed. The processes were soil erosion and wildfire risk; the pressures comprised land use conflicts, leachates from domestic and industrial waste, arable f ...

- Abstract:
- ... Desalination and water treatment by reverse osmosis (RO) can highly increase clean water supply in today's world. However, biofouling of polyamide (PA) RO membranes is a serious obstacle for a wider use of this technology. One of the promising ways of biofouling control is membranes surface modification with zwitterionic polymers. A number of published works showed that zwitterionic coatings can i ...

- Abstract:
- ... Material flow analysis (MFA) is a useful methodology to describe and quantify complex systems based on the law of mass conservation. It was further adapted to suit the specific conditions in developing countries where the available data is scarce and uncertain. The ‘adapted MFA’ methodology optimises the number of parameters, describes these parameters as probability distributions and assesses the ...

These wastes have a high content of organic matter, nitrogen and phosphorus that can be converted or recovered into valuable products. The valuation of swine waste by anaerobic digestion has already been assessed, but no systematic review on ...

- Abstract:
- ... Coastal aquaculture can contribute to eutrophication of receiving waters. New technologies and improved management practices allow the aquaculture industry to be more sustainable and economically viable. Current practices, however, do not provide an additional use for effluent water. Nitrogen, phosphorus and other effluent compounds could be valuable plant nutrients. Inflow and effluent water from ...

- Abstract:
- ... The recycling of greenhouse effluents in soilless cultivation systems is environ-ment-friendly, since the waste of water and the disposal of nutrients to the environ-ment is drastically reduced or even eliminated. However, a long-term recycling of the effluents may result in accumulation of Na+ and Cl- in the recycled nutrient solution. The major aim of the present research was to test the perform ...

- Abstract:
- ... High PHA production and storage using palm oil mill effluent (POME) was investigated using a laboratory batch Bio-PORec® system under aerobic-feeding conditions. Results showed that maximum PHA was obtained at a specific rate (qₚ) of 0.343C-mol/C-molh when air was supplied at 20ml/min. The PHA yield was found to be 0.80C-mol/C-mol acetic acid (HAc) at microaerophilic condition and the mass balance ...

This article describes changes in biogeochemistry of a pristine stream after receiving untreated sewage of an urban nucleus. Water samples were collected and field parameters measured, during low flow perio ...

Microalgal treatment of raw sewage presents many complexities, mainly resulting from the inability of the algal species to sustain increased physiological stresses due to variable nutrient levels and high concentrations of organics. Chlorella sorokiniana and Scenedesmus obliquus have been identified to tolerate higher amounts of organic loading and physiological stresses. Nutrient removal, pathoge ...
