  • "Escherichia Coli" inhibition in municipal wastewater treated in microalgae based treatment systems
    Krivograd-Klemenčič, Aleksandra ...
    . Municipal wastewater (WW) is usually treated in central WW treatment plants and afterwards discharged into water bodies without reuse. Due to its richness with nutrients it is causing ... eutrophication of water bodies and irreversibly deposition of phosphorus in sediments. Increasing urbanization and growing pressure on water supply and food production is leading to the development of source separation technologies with black, grey and yellow water to enable water reuse and to obtain new fertilizers for food production. Blackwater (BW), WW from toilets, represents less than 1% of the municipal WW, however it contributes 90% of total nitrogen, 75% of total phosphorous and most of the pathogenic microorganisms. Microalgae based WWT systems are one of most promising technologies for nutrient recovery from WW with benefits such as pathogen inhibition, carbon dioxide mitigation, oxygen production and biomass production, which can be used as a fertilizer, feed, source for production of chemicals, biofuels and other byproducts. Microalgae can inhibit growth of pathogen bacteria indirectly by raising the pH and dissolved oxygen concentration (DOC) due to photosynthesis activity or directly by excreting bioactive substances.
