IX. PRE-TREATMENT REQUIRED FOR
REVERSE OSMOSIS SYSTEMS.
It is advisable to ensure that raw feed water is microbiologically
safe and/or has been subjected to a purification process, if
this has not occurred or in doubt, Disinfection should be a
considered step by injecting liquid chlorine (preferably) and
allowing a contact time of at least 30 minutes. As part of a
primary pre-treatment it is recommended that the following
be considered in a pretreatment installation:
1. Sediment filter
: These filters are designed to remove sedi-
ment present in the raw water and are important to prevent
dirt from reaching the membrane and fouling it quickly.
Various filtering materials such as: multimedia, silica sand,
cartridge or bag filters may be used.
2. Activated carbon filter:
The membranes (central part) of the
Reverse Osmosis system cannot tolerate chlorine. It is extremely
important to give proper maintenance to the unit by changing
carbon filter material within recommended time frames, doing
this will increase the lifetime of the membranes.
3. Water softener:
When you have hardness of > 100 ppm,
to avoid saturation and fouling of the membranes a water
softener is recommended before Reverse Osmosis.
