Acid reverse osmosis membrane cleaning agent

1. Product performance

Reverse osmosis membrane cleaning agent EQ-501 is a liquid formulation of low pH, fouling to remove metal hydroxide, calcium carbonate, and other salts, it is suitable for the aromatic polyamide reverse osmosis membrane, hollow fiber membrane, nanofiltration (NF) and ultrafiltration (UF); excellent cleaning effect can prolong membrane transport

Do the time.

1) it is suitable for all aromatic polyamide membranes and acetic acid membranes.

2) low foam formula;

3) the dilution of PH was kept between 2 and 4.

4) liquid medicine can shorten the mixing time.

5) can be mixed with water at any ratio.

Two. Technical indicators

Appearance: light yellow sticky liquid

PH (1%): less than 2.0-3.0

Specific gravity (20 g/cm3): 1.15 + 0.03

Minimum preservation temperature: -15 C

Shelf life: 12 months

Three. Methods of use

It is usually added to the cleaning box with a concentration of 2 to 4%.

Four. Cleaning instructions

1) check and rinse the whole RO cleaning system to keep clean.

2) before cleaning, the type of contamination of RO membrane elements and the cause of the pollution must be basically clear. We should basically do the right thing. After cleaning

The causes of pollution are analyzed, and the corresponding preventive measures are made.

3) during the cleaning process, the temperature of the cleaning liquid should always be kept in the temperature range of 25~35 degrees C.

4) the flow of cleaning should be recommended by the film manufacturer or the drug supplier. In addition, the large and small volume of the flow and the length of the soaking time should be based on the membrane element

The type of pollution and the degree of pollution are determined. Without the recommended value, the technical engineer of the ExLen can give guidance according to the actual situation of the system.

5) for the system with more serious pollution, ExLen technical engineers should be consulted in the cleaning process to get better cleaning scheme.

6) multi segment RO system, each section should be cleaned individually to get better results. If the lotion is cloudy or the pH value exceeds the recommended range, it needs to be renewed

Preparation of lotion or supplementary cleaning agent.

7) the system must be washed with RO water before reinvesting.

Five. Packaging specifications

The liquid reverse osmosis membrane cleaning agent is packed in 25kg/ barrel, and its physicochemical properties are stable, stored in the cool place, and the storage period is 12 months.

Six. Safety and protection

Membrane cleaning agent EQ-501 is acidic, wear protective glasses and gloves when used, splash on the skin and rinse and rinse.
