Protozoa in Wastewater Treatment: Function and Importance

摘要: Protozoa constitute a major link between the highly productive and nutrient retaining microbial loop metazoans of classical food web. are efficient at gathering microbes as food, they sufficiently small to have generation times that similar those particles on which feed. They are, in quantitative terms, most important grazers aquatic environments, balancing bacterio-plankton production. not only play an ecological role self-purification matter cycling natural ecosystems, but also artificial system sewage treatment plants. In conventional plants ciliates usually dominate over other protozoa, number species total count biomass. It is generally accepted their feeding bacteria improve treatment, resulting lower organic load output water treated wastes. Due biodegradation potential some attempts been made use specifically environmental biotechnology. As biosensors could provide valuable information regarding adverse effects chemicals this part biocoenosis essential for effective operation biological waste-water processes.
