Methods of Physical Water Filtration:

5
Consists of glauconite coated with manganese oxide
Ideal for filtering dissolved iron, hydrogen sulfide and manganese
Often requires pretreatment with an oxidizing agent

6
Consists of at least 3 different layers of filtration media
Ideal for filtering suspended solids and
particles larger than 10-25 microns
Does not remove viruses, bacteria or small protozoans

7
Uses a barrier membrane to remove suspended solids
Ideal for filtering particles down to 0.1-10 microns (e.g. algae, protozoans)
Does not remove dissolved contaminants
May be used to reduce suspended solids to protect reverse osmosis membranes

8
Uses a barrier membrane to remove suspended solids
Ideal for filtering particles down to 0.01 micron (e.g. bacteria and some viruses)
Does not remove dissolved contaminants
Often used as pretreatment upstream of RO systems on water high in small suspended solids
Protects membranes by reducing the silt density index (SDI)

9
Uses a semi-permeable membrane to remove suspended solids and some dissolved solids
Ideal for filtering particles down to 0.001 microns (e.g. bacteria, viruses, divalent and trivalent ions)

10
Uses a semi-permeable membrane to remove suspended solids
Ideal for filtering contaminants down to
0.0001 micron (e.g. dissolved ions,
bacteria, and viruses)
One of the most cost-efficient technologies for deionization (removes up to 98% of dissolved ions with a single pass)
