Classification of main water treatment processes applied

01 - Conventional treatment

'Conventional treatment' includes water treatment that involves disinfection; coagulation/flocculation; clarification, sedimentation; and, granular media filtration

02 - Direct filtration

'Direct filtration' includes water treatment that involves disinfection; coagulation/flocculation; and, granular media filtration.

03 - Granular media filtration

'Granular media filtration' includes water treatment that involves disinfection; and, granular media filtration.

04 - Cartridge or bag filter

'Cartridge or bag filter' includes water treatment that involves disinfection; and, cartridge/bag filter.

05 - Slow sand filtration

'Slow sand filtration' includes water treatment that involves disinfection; and, slow sand filtration.

06 - Granular media filtration with other filtration

'Granular media filtration with other filtration' includes water treatment that involves disinfection; granular media filtration; and, either slow sand or cartridge/bag filtration.

07 - Membrane filtration

'Membrane filtration' includes water treatment that involves disinfection and membrane (micro, ultra, nano filtration or reverse osmosis).

08 - Membrane filtration with other filtration

'Membrane filtration with other filtration' includes water treatment that involves disinfection and membrane filtration combined with other filtration such as slow sand or cartridge/bag.

09 - Disinfection only

'Disinfection only' includes water treatment that involves disinfection only.

10 - Disinfection and other (unfiltered systems)

'Disinfection and other (unfiltered systems)' includes water treatment that involves disinfection and any other unfiltered system.

11 - No treatment

12 - No disinfection with other treatment

'No disinfection with other treatment' includes water treatment that does not involve disinfection. This may include some systems that use filtration processes.
