This chapter provides a general overview of physical–chemical wastewater remediation systems in the food industry. Water reuse systems are becoming more and more interesting and promising technologies, depending on merely quantitative estimations, physical and chemical features of pollutants and the variability of these characteristics, week after week. Different systems are available for the f...

Numerous contemporary incidents demonstrate that conventional control strategies for municipal tap water have limited ability to mitigate exposures to chemicals whose sources are within distribution systems, such as lead, and chemicals that are not removed by standard treatment technologies, such as perfluorooctanoic acid (PFOA)/perfluorooctanesulfonic acid (PFOS). In these situations, point-of...

The fluoride concentration in ground water was determined in Sankarankovil block of Tirunelveli district of Tamilnadu (India) where it is the only source of drinking water. Various other water quality parameters such as pH, electrical conductivity total hardness and total alkalinity as well as calcium, magnesium, carbonate, bicarbonate and chloride concentrations were also measured. A systemati...

INTRODUCTION The science of water disinfection is still a relatively new field for the tree fruit industry, as the widespread use of water disinfectants in this marketplace has only been occurring over the past couple of decades. In comparison, industrial water systems such as open recirculating cooling systems and evaporative condensers have been receiving chemical treatment for over five deca...

  In this study, chemical quality of Zayandehrud river between Zayandehrud Regulating Dam and Nekouabad Diversion Dam, three discharging drains and one Fehlman well were measured using HPLC with determine the pollution concentration of diazinon insecticide from July 2006 to March 2007. Also, Zayandehrud’s assimilative capacity was determined. The results showed that river water and drains were ...

The Agilent 6540 Q-TOF LC/MS and Agilent Mass Profiler Professional Software (MPP) were used to sensitively characterize the complex chemical composition of municipal wastewater. The processing of Q-TOF high-resolution MS data using the MPP multivariate statistical analysis package revealed changes in the occurrence patterns of organic chemicals during water treatment. Using this technique, we ...
