10 Steps To Clean RO Membrane And Why Is It Required To Change An RO MEMBRANE


10 Steps To Clean RO Membrane And  Why Is It Required To Change An RO MEMBRANE

As we all know that Successful membrane cleanup depends on the effectiveness of the cleanup compounds, their application, and the design and operation of the cleanup equipment. For the most effective results, RO Membrane cleanup ought to be performed with cleaning chemicals.

Steps to clean RO Membrane:

The following general chemical cleansing procedure is often followed, however, to work out the optimum cleansing procedure for your Ro System. Check out the steps here:

  1. Inspect the cleaning tank, hoses, and cartridge. Clean tank and flush hoses if necessary. Install new cartridge.
  2. Fill the cleaning tank with Ro permeate or DI water. Activate the tank recirculation pump.
  3. Slowly add chemicals to the cleaning tank supported by the CIP total volume and the product strength required and permit it to combine completely.
  4. Check solution temperature. If the temperature is not up to the counseled level, modify heating management to produce the optimum temperature.
  5. Check the pH of the solution. The pH is ought to be <12 or as counseled by the membrane manufacturer. If pH is simply too low, modify pH upward with hydroxide or another chemical as the membrane manufacturer counsels. If pH is simply too high, modify with acid.
  6. Circulate the solution through one stage at a time within the direction of feed flow for half an hour. Calculate the flow rate counseled by the membrane or system manufacturer.
  7. In cases of serious fouling, the first return flow is to be released to empty to prevent deposition of removed solids. For optimum results, every stage should be cleaned one by one in a multistage system.
  8. If the primary stage cleaning solution becomes opaque or stained, dump the tank and prepare a fresh cleaning solution before continuing. If the solution pH or temperature moves out of the counseled, a replacement solution is ought to be kept ready.
  9. Rinse with Ro permeate before returning the system to service.
  10. When returning the unit to service, drain out the water till any residual cleaning solution has been rinsed from the system.

Why is it required to Clean RO Membrane?

There is a maximum of two choices when it comes to repairing an RO Membrane Filter. Either, you will need to replace it or choose a maintenance service. Please note, you need to keep the manufacturer’s manual intact. it'll have info on the periodic schedule of replacement of membranes. Also, the replacement or repair of membranes accounts for the most important factor i.e. maintenance prices.

You need certain information to be made sure that:

  • Your members of the family get access to pure water.
  • Enhance the lifetime of the RO Plant.
  • A steep decline in maintenance value
  • You do not suffer from fraud by unqualified technicians.

Reasons to ensure the above:

So, before attending to the main points, allow us to consider why you have to modify RO Membrane?

You need to ensure the below-mentioned facts in thought –

  • The level of impurities within the water.
  • Hardness or proportion of total dissolved solids(TDS) in water.
  • The amount of water required for your daily use.

When is it required to change the RO Membrane?

RO Membrane is that the most significant part of any RO Water Plant. RO Membrane Filter is the actual filter that's doing all the work, the Sediment Filter and Carbon Filter are used for getting the water ready for the RO Membrane Filter so that it doesn’t get broken.

If you are taking excellent care of the sediment and carbon filters, and replace them at the specified intervals then the RO Membrane will need to be modified after purification of 4000 to 6000 liters of water.

The Reverse Osmosis Membrane lifeline depends on the TDS level in the water. The replacement is going to be decided based on the consumption of water, quality of input water, and potency of sediment filter and carbon filter.

Typically, RO Membranes Filter lasts for a minimum of 2-3 years, some even go as long as five years. Your RO Membrane could get damaged if you've got extremely hard water or if you ne'er flush the membrane.

The best way to know when to replace your RO Membrane Filter is to see the TDS level of purified water. You will need to have a TDS meter to identify the TDS level. You can get it on market easily if you don’t have one.

If the TDS level is found to be high, then the RO Membrane is going to get damaged soon. This could happen all of a sudden. So, it Is recommended to change the RO Membrane every 2-3 years.


I wrote this blog with two main reasons: to make you aware of the procedure for cleaning the RO Membrane, and the second is for letting you know the importance of changing it.

We all understand that an RO Plant is quite expensive as compared to other kinds of water purifiers but it is necessary to purify high TDS water. The maintenance cost is also high owing to pricey filters and membranes.

Apart from the price, we should also understand that RO System helps in reducing wastage of water as an RO water Plant purifies around 70-80% of wastewater.

Pearl Water Technology provides you with a wide range of RO membranes as per your specific requirement. You can visit our site for details.

Hope this blog was useful to you and you will follow the mentioned points and take good care of your RO System. If you have any queries, then feel free to call our expert at 9582215137.
