“…Generally, resins can withstand hardness and TDS levels of 500-2000 and 5000-30,000 mg/L, respectively [6]. Combining anion and cation exchange in RO pretreatment has been proven to increase the flux in subsequent RO operations [98]. Murray-Gulde et al [84] employed a hybrid filtration/cation exchange/RO system for treatment and reuse of waters that have interacted with an oil field (Figure 6).…”

“…Lime softening and ion exchange softening are two common methods for the removal of hardness [3,4,11] along with nanofiltration, membrane processes, electrochemical techniques, reverse osmosis, and biological processes [12][13][14][15][16]. Compared to the drawbacks of the lime method include the production of a high volume of sludge stream and excessive use of chemicals [17], the advantages of ion exchange include effectiveness, selectivity, recovery, fewer precipitation, and better economics in water softening [18][19][20].…”

“…It is difficult to determine a molar ratio of DOC to chloride anions as the molecular weight and the number of potential ionic groups of the DOC involved in the exchange are usually unknown. Indarawis and Boyer (Indarawis and Boyer, 2013) proposed the use of the charge density titration for DOM to determine the concentration of DOM (meq/l) given the pH of that sample if the factor needs to be estimated K DOC/Cl .…”

“…The set of anions was selected taking into account the average composition of the Llobregat River water and their interest as pollutants or responsible for DBPs formation (López-Roldán et al, 2015, 2013a. Both MIEX concentrations provided a fast and efficient removal of the evaluated anionic species and comparable to those for DOC measured indirectly as UV254 (Boyer, 2013). The higher the MIEX concentration, the higher the rate of sorption and the higher the anions removal.…”
