Aqualine Surface Water Treatment Systems

AQUALINE SURFACE WATER TREATMENT SYSTEMS


Technologies used include coagulation-flocculation-simple or lamellar precipitation, pressurized or gravity rapid sand filtration, slow sand filtration for clarification of turbid and humic waters; ion exchange for hard water treatment, ion exchange for salinity removal and reverse osmosis; There are biological treatment for the removal of organic substances, activated carbon adsorption, chlorination, ozonation and ultraviolet methods for disinfection.


COAGULATION:

Chemical substances are added to the water in order to turn the non-precipitating colloidal substances and slowly precipitating suspended solids in the raw water into rapidly precipitating flocs. Quick mixing by adding chemicals to the water, destabilizing the colloidal and suspended solids and combining the destabilized solids are called coagulation.


FLOCULATION:

Flocculation is the process of combining the small flocks destabilized as a result of the coagulation process by slow mixing and forming large flocs that can settle quickly. Slow mixing is done by mechanical mixing, air mixing and hydraulic mixing.


FILTRATION:

Filtration is the process of passing water through a filter medium to retain unsettled suspended solids in chemically coagulated and precipitated raw water and to obtain high quality drinking water.
