1. What is RO membrane cleaning chemical?
RO membranes are one of the crucial components in modern water treatment systems and water purifiers. To achieve this, RO membranes need to be maintained under clean conditions. Therefore, cleaning these membranes is extremely important.
After a period of water treatment, the surface of RO membranes will accumulate a lot of inorganic substances, iron, manganese, aluminum, bacterial remains, microorganisms. At that point, it is necessary to clean them before continuing to use to ensure the quality of the water source.
RO membrane cleaning chemicals are a type of chemical used primarily to dissolve and remove precipitated impurities adhering to the membrane. This helps to enhance the lifespan of RO filter membranes.
The common characteristic of these chemicals is their stable pH buffering property throughout the dilution process. They can effectively clean various types of membrane fouling. These chemicals exist in liquid form, making them very convenient to use.
2. When to use RO membrane cleaning chemicals
Typically, after about 3 - 6 months of use, RO membranes may become contaminated and need to be cleaned to ensure the water source's quality. However, the cleaning time of the filter membrane may vary depending on the characteristics of the water source.
According to experts, if the following signs are observed, consider using chemicals to clean the RO membrane:
- The water production through the membrane is reduced by 10 - 15%.
- The salt ratio in the produced water through the membrane increases by 5 - 10%.
- The pressure difference between the inlet water stream minus the pressure of the produced water stream increases by 10% - 15%.
- The pump pressure increases by 10% - 15%.
- The pump operates continuously, but the produced water is reduced or not flowing out.
- The amount of wastewater discharged from the water purifier is much higher than usual while the produced water is less.
- The pump operates continuously without stopping.
3. Notes when using RO membrane cleaning chemicals
- The water source used to rinse the membrane after cleaning with chemicals must be pure water, free from chlorine.
- When cleaning RO membranes with chemicals, it is necessary to carefully control the temperature, pH according to the manufacturer's standards.
- Avoid skin and eye contact with chemicals by using protective gear such as gloves, goggles, and masks.
- Avoid smelling or inhaling chemicals nearby. Isolate them from flammable substances. Keep them away from excessively hot or cold temperatures.
- If the cleaning chemicals come into contact with the skin, rinse thoroughly with water and seek medical attention nearby.
- If chemicals come into contact with the eyes, rinse the eyes continuously with clean water for 15 minutes. Then, seek medical treatment.
- If chemicals are swallowed, rinse the mouth continuously and drink plenty of water. Do not induce vomiting. Quickly seek medical attention for examination and treatment.
4. Instructions for using RO membrane cleaning chemicals
- Use alkaline chemicals to clean RO membranes if the substances adhering to the membrane are organic, adhesive, or biological sludge. (Only use RO membrane cleaning chemicals in the acid group when it is certain that the membrane only has calcium carbonate or iron oxide/hydroxide scale).
- Next, use acidic chemicals to clean the membrane. Note that this substance may react with silica, organic matter, and organic sludge. Therefore, it may reduce the operating efficiency of the RO membrane after cleaning. Therefore, use it when the alkaline solution has removed all dirt from the membrane.
- The cleaning process must ensure suitable pH and temperature conditions.
- If the cleaning solution is cloudy or dark in color, it should be replaced and repeat the membrane cleaning with a new chemical solution.
