Chemical Coagulation Treatment Using Alum and PACl in Complex Wastewater [PDF]
Korean Journal of Environmental Health Sciences, 2009 In order to treat the complex wastewater containing organic compound and solids, pre-treatment system associated with molecular separation process were investigated. The reductions of COD and turbidity were obtained after coagulation processes using Alum (Aluminium sulfate, ) and PACl (poly aluminium chloride as 17% ).

How Asian Should Asian Law Be? – An Outsider’s View [PDF]
, 2018 Is there an Asian identity of Asian law, comparable to European identity and therefore similarly useful as a justification for unification projects? If so, what does it look like? And if so, does this make Asia more like Europe, or less so?
