Organic pollutants particulate effluents

When real water is chosen (option 1), one must decide on what pretreatment to use to remove particulate matter, biological species, and organic pollutants. Because ionic mixtures are used in options 1 and 2, the effluent freshwater produced must be analyzed using offline individual ion detection, such as inductively coupled plasma in combination with optical emission spectroscopy or mass spectroscopy. However, in option 3, when using only single salt solutions, the measurement of conductivity is sufficient. In single salt solutions, we have to consider that the diffusion coefficients of the anion and cation may be (almost) equal (KCl) or are different (NaCl). 

As indicated above, industrial wastewater contains avast array of pollutants in soluble, colloidal, and particulate forms, both inorganic and organic. In addition, the required effluent standards are also diverse, varying with the industrial and pohutant class. Consequently, there can be no standard design for industrial water-pohution control. Rather, each site requires a customized design to achieve optimum performance. However, each of the many proven processes for industrial waste treatment is able to remove more than one type of pollutant and is in general applicable to more than one industry. In the sections that follow, waste-treatment processes are discussed more from the... 

Aquatic particulate matter is an important sink for numerous lipophilic anthropogenic contaminants as the result of adsorption and accumulation processes. In the adsorbed state organic contaminants can be subject to transformation as well as to transportation processes within the river system. The anthropogenic contribution to the organic load of river systems can be attributed mainly to sewage effluents derived from industrial and domestic point sources, to agricultural emissions or to shipping activities. Numerous specific compounds reflect the different sources of pollution and, therefore, are frequently detected in river systems.
