Filterlogic 4" x 40" Reverse Osmosis Systems Membrane Window Cleaning Description

Industrial RO Membrane

Introduction

Filterlogic RO membrane elements are widely used in water treatment and material separation and

have improved impact resistant and antipollution property.

The tech specification specifies the basic structure, type model, performance, package, transportation,

Storage and attentions

Operating Limits

Membrane Type……………………………………………………….……..Polyamide Thin-Film Composite

Maximum Operating Temperature……………………………………..…..113°F(45°C)

Maximum Operating Pressure………………………………………..…….600psi(41bar)

Maximum Pressure Drop…………………………………………….……..15psi(1.0bar)

Maximum Pressure Drop for Individual Element…………………….…...15psi (0.1Mpa)

pH Range, Continuous Operationa……………………………………….. 3-10

pH Range, Short-term Operation(30 min)b………………………………..2-12

a. Maximum temperature for continuous operation above pH 10 is 95°F(35°C)；

b. Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation

Damage is not covered under warranty, Filterlogic recommends removing residual free chlorine by pre-treatment prior to membrane exposure.

Product Package

RO membrane elements are vacuum packaging with polyethylene bag and have corresponding mark.

Product Transportation and Storage

Do not add any influential chemical agent to membrane element during storage

Membrane elements storage place must be cool and dry, and without direct sunlight.

The temperature range must be 0-40°C during transportation and storage.

Strictly prohibit throwing the package during transportation.

Attentions

Each membrane element passed test and did store treatment by 1.0%sodium hydrogen sulfite (will add 10% propylene glycol anti-freezing

Solution in the winter), vacuum package, then pack by carton. In order to avoid microbial growth, we suggest soak the element and use the

Protective liquid including 1.0% sodium hydrogen sulfite (which from RO membrane).

When the element is first used, the first tank permeate from RO membrane element should be discard.

Do not add any influential chemical agent to membrane element during operation.
