“…Pressured by water scarcity and increases in water demand worldwide, treated wastewater has been reused for a variety of purposes over the last few decades, including agricultural irrigation and other industrial, environmental and municipal uses [1,2]. The potential for water reuse is dependent on effective pathogen removal.…”

“…The potential for water reuse is dependent on effective pathogen removal. The disinfection process, generally the last step in wastewater treatment, aims to minimize the risk of pathogen exposure in receiving environments in order to protect public health [2]. However, the removal efficiency of pathogenic organisms can vary greatly and depends on the type of treatment process.…”

Treatment in a wastewater stabilization pond (WSP) relies on natural purification processes, which can be sensitive to both location and climate. This study investigated the effects of three environmental factors, pH, dissolved oxygen (DO) and temperature, on disinfection efficiency in a WSP system consisting of three facultative cells, and operated in a temperate climate region, in Eastern Ontario, Canada. Indicator organism (Escherichia coli (E. coli)) removal in WSP systems is driven by a combination of different factors. Elevated pH and DO concentrations, which are attributed to the presence of algae, are important factors for effective disinfection. Therefore, the presence of algae in natural wastewater treatment systems can contribute appreciably to disinfection. Consequently, based on algal concentrations, removal efficiencies of pathogenic microorganisms during wastewater treatment over the course of a year can be highly variable, where higher removal efficiencies would be expected in summer and fall seasons.

“…because of its abundance and its medical significance as an agent of human infections such as amoebic keratitis and granulomatous amoebic encephalitis. Another area of concern regarding FLA in water is their relationship with waterborne pathogenic bacteria, including Legionellaceae, Mycobacteriaceae, Enterobacteriaceae, Vibrionaceae and many others (Mosteo et al 2013).…”

Dreissena polymorpha (the zebra mussel) has been invading freshwater bodies in Europe since the beginning of the nineteenth century. Filter-feeding organisms can accumulate and concentrate both chemical and biological contaminants in their tissues. Therefore, zebra mussels are recognized as indicators of freshwater quality. In this work, the capacity of the zebra mussel to accumulate human pathogenic bacteria and protozoa has been evaluated and the sanitary risk associated with their presence in surface water has also been assessed. The results show a good correlation between the pathogenic bacteria concentration in zebra mussels and in watercourses. Zebra mussels could therefore be used as an indicator of biological contamination. The bacteria (Escherichia coli, Enterococcus spp., Pseudomonas spp., and Salmonella spp.) and parasites (Cryptosporidium oocysts and free-living amoebae) detected in these mussels reflect a potential sanitary risk in water.

“…A clear picture of the quality of the treated wastewater and calculated values are presented in Table 3. Note that these values are the result of the best conditions and the highest efficiency (Mosteo, 2013). The standard table of environmental criteria for quality can be seen further in the text.…”

The available research was managed to monitor the physicochemical and microbiological features of treatment plants. The wastewater treatment herb sewage is a straight pollution input source for anthropogenic pollution. The sediment information ideas to an urban drainage trench as a secondary point pollution source while the organotins information highlights the presence of other spread sources, special to this material. wastewater re-use in urban has increased in many realms. The consequences of the study display that among the offered treatments, the best for asepsis and reducing microbial pollution of urban outlet effluent is that of the plus 0.25 weight percent Permanganate filter. Due to the amount of demand and need for the use of wastewater and circulated waters in agriculture, now most of wastewater treatment plants in the IRAN are designed and administered with the goal of reusing the wastewater produced in agriculture. Using wastewater increases the functioning of plants and does not have negative effects on the properties of the soil and its permeability. At the time in numerous cities of the IRAN the urban sewage and surface runoff which leave the cities, are used in farms downstream. The best option for the microbial disinfecting of the outlet wastewater in urban wastewater treatment plants among the treatments presented belonged to the plus 0.25 weight percent of potassium permanganate powder filter treatment. So that the percentage of the elimination of microbial pollution reached more than 99.99% Using this treatment in urban wastewater treatment plants can increase the microbial quality of wastewater to very high values, which can be utilized in farms, nutrition of groundwater resources, entrance to surface waters, Irrigating the green space, use in car-washes, etc.
