The simultaneous removal of turbidity and humic substances from water using the enhanced coagulation process
This study aimed to investigate the efficiency of the enhanced coagulation (EC) process for the simultaneous removal of turbidity and humic substances (HS) from raw water from the Sanandaj Water Treatment Plant (SWTP). This study was conducted on a laboratory scale using a jar test device and ferric chloride (FeCL3) as the coagulant. Accordingly, the effects of pH and coagulant dosag...
متن کاملTailoring Properties of Polyaluminum Coagulants
24 Aluminum coagulants are widely used in water treatment plants to remove turbidity and 25 dissolved substances. However, because high aluminum concentrations in treated water are 26 associated with increased turbidity and because aluminum exerts undeniable human health 27 effects, its concentration should be controlled in water treatment plants, especially in plants 28 that use aluminum coagu...
متن کاملSteady-state humic-acid-containing blanket in upflow suspended bed.
We investigated the effects of turbidity and concentration of humic acid on the steady-state behavior of the blanket, which was coagulated using polyaluminum chloride (PACl) as coagulant. The three-dimensional solid-flux plot was constructed. Based on fixed PACl dosage, the iso-humic-acid solid-flux surfaces stacked that enveloped the feasible regime for the blanket bed. The steady-state point ...

15 صفحه اولEffect of Al(III) speciation on coagulation of highly turbid water.
In Taiwan, the turbidity of raw water for fresh water treatments can sometimes reach as high as 40000 NTU due to intensive rainfall, especially in typhoon seasons. In response, water works often apply large quantities of coagulants such as polyaluminium chloride (PACl). In this study, simulated and natural highly turbid water was coagulated with two PACls, a commercial product (PACl-1) and a la...
