“…Turbidity is an essential indicator of water quality [1]. Turbidity detection is widely applied in various fields [2,3], such as environmental, chemical, and pharmaceutical sciences [4], water treatment plants [5,6], municipal water supply and drainage networks [7,8], river and lake management [9,10], beverage industries [11,12], power plants [13], and so on. The online turbidity meter is widely used [3] and has different designs for various applications [9,14,15].…”

To explore the feasibility of the online turbidity meter installed in-line, we have to study the influence of flow velocity on in-pipe turbidity detection. In the laboratory self-designed water circulation system, the correlation between the in-pipe turbidity and flow velocity was studied by altering the water flow rate in the pipe. The results show that the in-pipe turbidity and flow velocity have a benign linear relationship for the slow flow; as the flow velocity increases, the in-pipe turbidity increases slightly but is limited. However, there is no significant correlation between the in-pipe turbidity and flow velocity for the fast flow.

“…18,19 One worldwide priority is the substitution of hazardous chemicals and substances of very high concern by environmentally benign materials. [20][21][22] Ultimately, new legislation has been proposed to ban the use of hazardous chemicals. 23 In this regard, searching for new environmentally benign materials from waste treatment and management is gaining scientists' and researchers' interest.…”

“…Other studies have suggested that the concentration of DBPs (trihalomethanes and haloacetic acids) and the levels of protozoa, such as Giardia and Cryptosporidium, in filter backwashing water are considerably higher than those in raw water [11,12]. In contrast, other researchers have found positive impacts, such as increased coagulation efficiency, reduced coagulant dosage, and enhanced turbidity removal [13,14]. However, there is still a need for discussion on the issue of the effect of recycling using recycled water from DWTS treatment units, particularly concerning the characteristics of DOM, such as humic-like and protein-like substances.…”

The recycling process is applied in many water treatment plants (WTPs), although this process can lead to adverse effects. The effect of the recycling process on the characteristics of dissolved organic matter was evaluated based on a fluorescence excitation-emission matrix using the peak-picking technique and self-organizing map (SOM). In this study, an evaluation of two WTPs, one with and one without a recycling system, was carried out. Both WTPs show moderate efficiency during the coagulation–flocculation process in removing DOC, fulvic acid-like, humic acid-like, and tryptophan-like substances. The recycling process causes increased values of fulvic acid-like, humic acid-like, and tryptophan-like substances and specific ultraviolet absorbance (SUVA) after the filtration process of about 31.0%, 35.7%, 22.2%, and 6%, respectively. Meanwhile, the WTP without recycling showed a reduction in the level of fulvic acid-like, humic acid-like, and tryptophan-like substances and SUVA by 23.3%, 52.9%, 27.8%, and 21.1%, respectively. Moreover, SOM analysis based on the peak-picking technique can determine differences in sample clusters due to the recycling process.
