Why is precise water quality control crucial in reverse osmosis?

Reverse osmosis systems act as an advanced filter that removes even the finest impurities from water - from salt particles and heavy metals to bacteria and organic compounds. This process produces high-purity water, which is essential for many industries such as food, chemicals, pharmaceuticals and energy. However, in order for the entire system to operate at maximum efficiency, it is crucial that the water quality is constantly monitored at each stage of filtration.

Why is this so important? Parameters such as pH, conductivity or chlorine concentration have a direct impact on the effectiveness of semi-permeable osmotic membranes. Too high a salt concentration or inappropriate water pH can lead to damage to the membranes, shortening their life and increasing operating costs. In turn, insufficient control over the filtration process can result in water quality that does not meet industrial requirements.

Precise monitoring not only allows problems to be detected quickly, but also prevents them from escalating. This ensures that the RO system operates stably and the company avoids costly downtime and repairs. This is why investment in advanced measurement technology is crucial to the success of such systems.

How to ensure consistent water quality in industrial reverse osmosis systems? The customer's challenge

Our client, a leader in the design and operation of reverse osmosis systems, had a challenging task: to ensure that the water treated by their systems was not only pure, but also perfectly matched to the requirements of industrial end users. To achieve this, reliable monitoring of water parameters - both before and after filtration - was crucial.

However, that is not all. The customer was struggling to manage a wide variety of measurements simultaneously. Data on pH, conductivity, oxygen or chlorine concentration came from different measurement points, making centralised processing and analysis difficult. Distributed monitoring systems were not only difficult to operate, but also increased the risk of errors and maintenance costs.

Another challenge was the need to integrate modern measuring devices into the already existing water treatment system. The customer expected solutions that would be easy to implement, but at the same time provide high measurement accuracy and reliability. These requirements became the starting point for developing a dedicated solution that met all expectations.

How are intelligent digital analysis systems changing industrial reverse osmosis? Our solution

In response to our client's needs, we proposed a solution with the Aquis Touch S transmitter and controller with on-screen recorder function at its heart. This modular device enabled the centralised monitoring and recording of all water quality parameters such as pH, conductivity and dissolved oxygen levels. By supporting multiple measurement channels, this device brought together data from different sensors in one place, eliminating the need for multiple independent systems.

The JUMO digiLine HUB, which allowed easy management of the digital sensors, was also an integral part of the system. It made connecting and integrating six different measurement sensors extremely simple. These sensors included specialised devices such as:

• JUMO tecLinepH electrodes for the precise measurement of water acidity and alkalinity,
• JUMO tecLine ORPredox electrodes, which measured the redox potential, crucial for controlling chemical processes,
• BlackLine Lf-GT/-ECconductivity sensors, providing accurate data on water conductivity levels,
• JUMO digiLine O-DO S10 optical dissolved oxygen sensor, essential for water quality monitoring.

The implementation of these devices allowed the automation of water parameter monitoring processes. Thanks to the modular design of the system, the solution was not only easy to implement in the existing infrastructure, but also flexible, allowing future expansion. Digitisation of the measurement processes reduced the risk of human error, accelerated data analysis and reduced the costs associated with system maintenance.

How does centralised monitoring simplify water treatment processes in RO systems? Customer benefits

Our centralised monitoring system has revolutionised the way our customer's RO systems are managed.

Key benefits include:

1. Simplified operations - Aquis Touch S centralises data, reducing system complexity.
2. Improved reliability - an advanced sensor network ensures precise measurements and greater system stability.
3. Significant cost reduction - digital integration eliminates the need for multiple independent devices and simplifies maintenance.
4. Future-proof infrastructure - modular solution supports system expansion as needs grow.
5. Technical support - guarantees peace of mind and continued system performance.

A centralised approach works best for maintaining key water quality parameters such as pH or conductivity in RO systems. With a single interface, customers can monitor multiple parameters, greatly simplifying the management of water treatment processes.

Industrial reverse osmosis systems - Frequently asked questions

What factors affect the performance of an RO system?

The performance of RO membranes is affected by water temperature, system condition, operating pressure and salt concentration in the water.

What is the most common problem with RO systems?

A common problem is the continuous flow of water to the drain. Ideally, these systems should only drain occasionally when the tank is full.

How often should the RO system be serviced?

Most filters in an RO system should be changed every 3-12 months and the whole system should be disinfected at least once a year.
