20-MICRON FILTER
The 20-micron filters remove suspended particles from the raw water 20-micron and larger in size. This provides
protection and longer life to the 5-micron filter.
The technical characteristics of the 20-micron filters are contained in table 8.

REVERSE OSMOSIS MEMBRANE ELEMENTS
The RO membranes convert high pressure raw water into potable drinking water by means of spiral wound
membranes. These membranes consist of one or more membrane envelopes that are formed by enclosing a
product water carrying material between two large flat membrane sheets. The membrane envelope is sealed on
three edges and is attached to a small diameter pipe to form a cylinder 4 inches in diameter and 48 inches in
length. A polypropylene screen is used to form the raw water channel between the membrane envelopes. A
special wrap is applied to the membrane element to help it maintain the cylindrical configuration when outside the
tube. ROWPU-1 has two elements connected in series to double the capacity of ROWPU-2.
The technical characteristics of the RO membranes are contained in table 10.
