Multi-Stage Filtration (MSF) Technology with Natural Coagulants for Raw Water Treatment from the Sinu River in Colombia


Objective: To determine turbidity removal efficiency of raw water samples, by using Multi-Stage Filtration technology and complemented with natural coagulants. Methods/Analysis: Water samples were taken from the Sinu River. A pilot plant was set up in laboratory, and treatability tests were carried out on samples with different scenarios. Findings: The best treatment for raw water was obtained when 240 m3 m-2d-1 rates were applied for 200 NTU initial turbidity. There were no alterations in pH and water alkalinity after treatability tests. Application: This raw water treatment technology is very useful and appropriate to be applied in rural areas with difficult access and scarce economic resources, since its simplicity does not require costly inputs or maintenance.
