“…In these cases, chlorine acted as a toxic potentiator rather than a toxic deactivator. Balancing the degradation of the chemical species and the risk from new toxic disinfection byproducts (DBPs) has become a major issue in water treatment [43].…”

“… Inorganic compounds, like chlorate, chlorite, and bromate ions, produced while chlorine dioxide and ozone disinfectants are utilized (Guo et al, 2014;Lou et al, 2009;Tian et al, 2014). Gopal et al (2007) presented a list of chlorination by-products (CBPs) and their toxicities (Table 1). They as well listed the guideline values in drinking water for CBPs (Table 2).…”

“…The maturation of municipal water purification in the last decades has authorized cities in the developed countries to be mostly without of waterborne diseases. Since the application of filtration and disinfection of potable water in the United States, waterborne diseases like cholera and typhoid have been almost removed (Bond et al, 2012;Weiner, 2012;Gopal et al, 2007;Liviac et al, 2011;Ghernaout et al, 2008;.…”

The generation, monitoring, and health impacts of disinfection by-products (DBPs) in potable water are problems of worldwide worry. Several nations, besides the World Health Organization, possess regulations and/or guidelines on bearable levels of DBPs in water. Since drinking water is frequently remediated using a chemical killing agent, DBPs are pollutants to which several humans are unprotected. On account of the health impacts linked to subjection to chlorinated water and/or some DBPs, the water manufacturing has performed great endeavors to equilibrate killing pathogens and DBP monitoring. Large survey has been realized on rising DBPs of health and regulatory worry. In spite of the fact that the attention on DBPs was previously on chlorine-and bromine-containing carbonaceous DBPs, appearing DBPs comprise iodine-containing species, also halogenated and non-halogenated nitrogenous DBPs. In addition, latest toxicity experimentation has proposed that certain of the more recent PBPs are of more elevated toxicity than some of the regulated chemical products. Therefore, survey has been realized to better comprehend how to costeffectively monitor a large interval of regulated and appearing DBPs. This comprises the usage of advanced remediation and killing pathogens methodologies. This paper shows certain of the newest research works at comprehending these significant DBP-related problems. Disinfection is killing microorganisms present in water; but, it is as well killing human beings drinking water by poisonous DBPs. Using chemicals for water treatment is finally a lost cause.

“…This disadvantage has emphasized the need for exploring alternative disinfectants and new treatment technologies (Gopal et al, 2007). In this respect, ozonation and UV-C irradiation have traditionally been tested and, to a certain extent, employed as disinfection methods due to the simplicity of operation and the relatively affordable operating and maintenance costs (Rice et al, 1981;Symons et al, 1989;Lin et al, 1999;Bonacquisti, 2006;Wait et al, 2007).…”

It is well known that chlorine and its compounds, traditionally utilized for water and wastewater disinfection, react with some organic matter to form undesirable by-products, hazardous to human health, known as Disinfection By-Products (DBPs). In many countries very stringent limits for chlorination by-products such as trihalomethanes were set for wastewater reuse. Accordingly, the use of different oxidation/disinfection systems should be evaluated as possible alternative to chlorine. Ultrasound (US) was recently found to be effective for this purpose.Aim of this work is to review main US disinfection studies, pointing out ultrasound mechanisms as well as its effects in terms of different bacteria inactivation (Total coliform, Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, Saccharomyces cerevisiae, Klebsiella pneumonia) at both laboratory scale and pilot-scale. To this end, several experimental results were discussed and both focal interest points and encountered problems were summarized.Moreover the intensification of cavitation phenomena by combined oxidation processes was overviewed and main advantages and disadvantages were pointed out, in order to address future research and promote efficient large scale operations.
