enhanced coagulation (ec) is defined as the addition of excess coagulation to improve the removal of disinfection by-product (dbps) precursors through the use of conventional water treatment processes. in this research, most of coagulants of ferric chloride (fecl3), poly aluminum chloride(pacl) in removal of most parameters of total organic carbon (toc), dissolved organic carbon (doc), organic ...

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...

the efficiency of existing municipal wastewater treatment plants has been affected by the increase of incoming organic load caused by the expansions in developing countries. in the present investigation, the effect of chemically enhanced primary treatment (cept) process was studied on the enhancement efficiency of a municipal wastewater treatment plant in tehran, iran. jar test results showed a...

This work assesses the efficiency of integrated enhanced coagulation and direct filtration processes for the removal of color, turbidity, and natural organic matter (NOM) from surface water. The processes were conducted in a simulated pilot. The operating conditions of the treatment process, including pH, FeCl3 dose, and influent flow, were investigated. Following that, its efficienc...

Enhanced immune cell trafficking into the central nervous system (CNS) and disruption of the blood brain barrier are pathophysiological hallmarks of neuroinflammatory disorders like multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE). However, recent studies suggest that the coagulation and the contact-kinin system might also be involved in MS developme...

Although the removal of colloidal particles continues to be an important reason for using coagulation, a newer objective, the removal of natural organic matter (NOM) to reduce the formation of disinfection by-products (DBPs), is growing in importance. Enhanced coagulation is thus introduced to most water utilities treating surface water. Bench-scale experiments were conducted to compare the eff...

The existence of trihalomethanes (THMs) in a drinking water plant of Nicaragua has been investigated in order to see whether the concentration exceeded the maximum contaminant level recommended by the environmental protection agency of the United States (USEPA) and the Nicaragua guidelines. The influence of pH, temperature, chlorine dose and contact time on the formation of THMs were studied. T...
