Abstract Purpose In addition to agriculture, energy production, and industries, potable water plays a significant role in many fields, further increasing the demand for water. Purification desalination play major meeting need clean drinking Clean is necessary different areas, such as industry, food generation everyday chores. Design/methodology/approach The authors have used search engines like...

Azo dyes are very resistant to light-induced fading and biodegradation. Existing advanced oxidative pre-treatment methods based on the generation of non-selective radicals cannot efficiently remove these dyes from wastewater streams, and post-treatment oxidative dye removal is problematic because it may leave many byproducts with unknown toxicity profiles in the outgoing water, or cause expensi...

The prevalence of enteric viruses in wastewater, the efficacy of wastewater treatments in eliminating such viruses, and potential health risks from their release into the environment or by recycling of treated wastewaters, are very important issues in environmental microbiology. In this study we performed a quantitative TaqMan real-time PCR (polymerase chain reaction) analysis of enteric viruse...

The present study proposes an integrated system based on the synergetic action of solar photocatalytic oxidation with surface flow constructed wetlands for the purification of wastewater contaminated with pesticides. Experiments were conducted at pilot scale using simulated wastewater containing the herbicide clopyralid. Three photocatalytic methods under solar light were investigated: the phot...

Passive wastewater treatment systems are commonly applied in northern Canadian communities. Pathogen removal in these systems, which relies on natural purification, can be greatly affected by Arctic environmental conditions. In 2012, new Wastewater Systems Effluent Regulations (WSER) were implemented in Canada, but not in the far North due to the number of northern communities with limited wast...

Dehydrogenase and catalase activities were measured in a Eutric Histosol irrigated with municipal wastewaters (Lublin, Poland) purified by a two-step (mechanical and biological) treatment. Soil enzyme activity was used to test the biochemical status of the soil-plant system, the last step of wastewater purification. Three experimental fields, each of 1 ha area, were planted with Populus nigra, ...
