E4H Series
Operation & Maintenance Manual

1. DESCRIPTION
Your E-Series reverse osmosis (RO) machine is a durable piece of equipment which,
with proper care, will last for many years. These instructions give operation and
maintenance details vital to the sustained performance of the machine. Please read
this manual completely before operating your machine.
1.1. Definitions
The operating definitions provided below will help you further understand your
machine and this manual.
1.1.1. Permeate Rate (Product Water Rate) [Q
p
]
The flow rate of purified water, which has passed through the membrane and out of
the membrane element, expressed in gal/min (gpm) or gal/hr (gph) or liter/min (lpm)
or cubic meters/hour (m
3
/h). Specified permeate rates are based on a feed water
temperature of 77
°
F (25
°
C). Permeate rate will vary with temperature.
1.1.2. Concentrate Rate (Reject Rate) [Q
c
]
The flow rate of water containing rejected solids to drain in gpm or gph (lpm or m
3
/h).
1.1.3. Feed Rate [Q
f
]
The flow rate of incoming water in gpm or gph (lpm or m
3
/h). Feed water rate equals
permeate rate plus concentrate rate.
1.1.4. Reverse Osmosis (RO)
The separation of one component of a solution from another component by means of
pressure exerted on a semipermeable membrane. In other words, reversing the
natural passage of a liquid from a concentrated solution to a more dilute solution by
using external pressure. Removal of ionic, organic, and suspended /dissolved
impurities occurs during the RO process. Unlike a filter, which separates by “normal”
filtration, the membrane element separates using a process called crossflow
filtration. Feed water solution is separated in to two streams, permeate and
concentrate, and collected from both sides of the membrane. A semipermeable RO
membrane, under sufficient pressure, allows passage of purified water while rejecting
and concentrating dissolved and suspended solids.
