BACKGROUND In recent years, decreasing annual rainfalls in some countries and population growth have led to a shortage of freshwater resources. Thus, recycled wastewaters has been suggested for agricultural activities. Contamination of wastewaters with pathogens is a major concern for the use of these waters. This study aimed to (i) investigate the occurrence of helminth eggs and protozoan (oo)...

Acidophilic, heterotrophic bacteria isolated from acidic mine effluent metabolised a range of aliphatic compounds. Aliphatic acids, which are normally thought to be toxic to acidophiles, were utilised as substrates for energy and growth by these bacteria. This biodegradative ability, concomitant with their tolerance of heavy metals, has demonstrated the potential for using these organisms for t...

Salvinia exhibit capacity for removing contaminants such as heavy metals, inorganic nutrients, explosives from wastewaters. Properties such as high productivity, high sorption capacity and high metal removal potential establish Salvinia as an aquatic fern with immense potential for use in phytoremediation technologies. Realizing capabilities of Salvinia, its role for mass scale use in phytoreme...

Biological treatments to degrade cyanide are a powerful technology for cyanide removal from industrial wastewaters. It has been previously demonstrated that the alkaliphilic bacterium Pseudomonas pseudoalcaligenes CECT5344 is able to use free cyanide and several metal-cyanide complexes as the sole nitrogen source. In this work, the strain CECT5344 has been used for detoxification of the differe...

The application of new technologies in the agro-industrial sector is needed to close loop nutrient cycle food chain. aim this work study feasibility combination two recovery technologies. In a first step, novel gas-permeable membrane technology recovers N from wastewater as an ammonium sulfate solution (a bio-based fertilizer). Secondly, electrodialytic process P, electrolyte solution, which P ...
