Impact of coagulation conditions on the in-line coagulation/UF process for drinking water production
An in-line coagulation (without settling)/UF process has been studied to improve membrane performance and water quality for surface water treatment. Using coagulation ...

Characteristics of dissolved organic matter after treatment by clinoptilolite-amended activated sludge in association with coagulation processes
... from a clinoptilolite amended activated sludge with regard to various sludge retention times (SRTs) singularly run or in combination with a coagulation process. First, four laboratory-scale activated sludge reactors were concurrently operated in SRT 5, 10, 20, and 40 days to treat the effluen ...

Effects of iron species and inert minerals on coagulation and direct filtration for humic acid removal
... behavior of various iron species (e.g. ferrous, prehydrolyzed(ph)-ferrous ion and ferric ion) as a coagulant and effects of inert mineral on the coagulation process combined with direct microfiltration (MF) membrane process was studied for humic acid (HA) removal. When 0.01 mM to 1 mM of the variou ...
