MPSFs are constructed
and operated in a similar manner to MSSF technology with all of the same
advantages.
MPSF based treatment systems are simpler and less expensive than treatment
systems using other filtration technologies.
|
Total height of filter similar to MSSF or shallower. Loading up to 600 litres per square meter of surface area. |
MPSF Based
Treatment Systems may be used to remove small particles such as:
-
Particulate matter (sand, silt or
clay sized particles with or without use of coagulants)
-
Iron (directly or using
pre-oxidation)
-
Manganese (directly or using
pre-oxidation)
-
Hydrogen sulphide (using
pre-oxidation)
-
Arsenic using pre-oxidation and
coagulants
-
Fluoride (using lime and coagulants)
-
Heavy metals (with use of
appropriate coagulants)
-
TOC/DOC (using coagulants or
pre-oxidation)
-
Algae (directly or with
pre-disinfection and use
of coagulants)
-
Parasites including Giardia Cysts
and Cryptosporidium Oocysts
-
Helminthes and their eggs
-
Spores

MPSF Based Treatment Systems may be used to
treat:
-
Surface water
-
Ground water
-
Ground water under direct influence
of surface water
-
Brackish or saline water as part of
pre-treatment for desalination process
-
Polishing filtration for municipal
wastewater that has been treated to tertiary (perhaps secondary) standards
-
Storm water runoff
-
Industrial or municipal wastewater
to condition satisfactory for reuse and recycle or disposal
-
Agricultural wastewater to condition
satisfactory for reuse and recycle or disposal
-
