Understanding Technical Problems in Reverse Osmosis

Reverse osmosis is a process that is used to remove particles, ions, and molecules from a solution. It is a powerful tool used in many applications, including water purification, desalination, and wastewater treatment. While reverse osmosis is a reliable process, it is not free from technical issues. Understanding the common technical problems associated with reverse osmosis can help optimize the process and ensure that it runs smoothly.

We do our best for customer satisfaction, so we are constantly inventing new things and looking for suggestions to improve the efficiency of our services. This time we will we are once again bringing you another batch of helpful instructional videos. We hope that you will find the answers to the questions raised through the offered images and that the material will positively enrich your understanding of our filtration equipment.

Reverse osmosis is a device that allows you to enjoy perfectly filtered water through several stages of filtration, without coarse impurities, without chlorine, without microorganisms (bacteria, viruses, fungi, etc.) and with a great taste. When the device is installed correctly (the installation procedure can be found on our Youtube), it works as it should and you have the benefits of treated water all year round. Nevertheless, problems can occur during the filtration process. , which we bring to your attention, along with the solution.

The following types of failures are most commonly reported to us:

1. Water is not flowing or the reverse osmosis system is filtering only a small amount of water into the reservoir.

a, The problem lies in the osmotic membrane

In this case, the problem may be with the osmotic membrane, which tends to become worn and clogged, so we recommend replacing it after 2 – 3 years of use. You can check its functionality at any time by using a TDS meter to measure water conductivity (amount of dissolved substances). Osmotic membrane functions correctly if the resulting values are 90% lower than the measured values of the input water.

b, The error is in the water tank

If we rule out a problem with the osmotic membrane, the error may be in the the water reservoir, which you can easily check by draining the water through the faucet. If the reservoir is heavy, it means that water remains in the reservoir and the reservoir needs to be pressurized. An ordinary pump containing a pressure gauge will suffice. The pressurisation should be done gradually so that it does not burst. Repeat the process until the water runs out. The pressure in the empty tank should start from 0,5 to 1 bar.

Another problem encountered is also low inlet water pressure. You measure the pressure using a barometer that you connect to the water inlets of the reverse osmosis system. A pressure of at least 4 bar is required for proper operation. If the pressure is less than 3 bar, a pump must be fitted as the water hardly flows.

2. Water constantly overflows into the fallout

As in the previous case, the osmotic membrane should be checked for functionality using a TDS meter and the inlet water pressure should be checked. If neither the membrane nor the low inlet pressure is at fault, it should be tested for damage to the four-way valve or check valve . procedure can be found in the video below .

3. What to do in case of a water leak?

In such a situation, it is necessary check the threads, which must be resealed with Teflon tape (available in our e-shop). If sealing the joints does not help, the cotter pin, which is used for the transition from thread to tube, must be replaced. If water is leaking around the quick coupling, the hose should be removed and checked for damage. If it is damaged, the hose should be cut 2 cm further into the plane and reconnected.

4. The water does not filter or pass into the waste

This malfunction most often indicates that there is a clogged flow restrictor. This case requires disconnecting the hose upstream of the flow restrictor, which should be under heavy pressure. If it does not push the water through, it needs to be replaced. Remove the supply valve and relieve the water pressure from the faucet.

If you encountered another problem while using your reverse osmosis system or your reverse osmosis system and you did not find a solution in the video, we would be happy to have you contact our customer service. You can contact us every working day online, by chat, by phone or by email. Don’t forget to visit our YouTube channel for more helpful video instructions.

What are common technical problems in reverse osmosis?

The most common technical problems in reverse osmosis include membrane fouling, high pressure drop, and inadequate system design. Membrane fouling is caused by the accumulation of organic and inorganic substances on the membrane’s surface, reducing the membrane’s performance. High pressure drop is caused by the accumulation of suspended solids, which can cause the membrane’s performance to decline. Inadequate system design can lead to insufficient pretreatment, which can result in membrane fouling and poor performance.
