Monitoring of installations for nanofiltration or reverse osmosis
Objective of water treatment or seawater desalination: clean drinking water or industrial process water. In nanofiltration or reverse osmosis installations, pre-filtered water flows through the pressure pipes with diaphragms that filter out substances dissolved as ions. Each individual pressure pipe must provide the specified water quality. Parameters such as water conductivity show whether the quality is right. Pollutants passing through the diaphragm cause the conductivity to increase. This then leads to a protracted search for the cause.
The flaws of conventional permeate monitoring
Manual sample collection It is a complex process to collect samples manually from individual pressure pipes, and documentation is error-prone. Samples are usually only collected on a sporadic basis, meaning that damage to the diaphragm is only detected late.
Conventional automated monitoring In automated monitoring, permeate collected from several individual pressure pipes is analysed. The result is an average value. The malfunctioning of individual pressure pipes or diaphragms is not detected.
No more troubleshooting in filtration
How do you find the fault if the water quality drops? Here at Bürkert, we have developed a system that allows you to monitor the permeate in every pressure pipe. Automatically.
If a diaphragm develops a fault, there is no need to search for it. Instead, you check in which pressure pipe the conductivity is rising and replace the diaphragm in good time. With the automated monitoring system, this helps you maintain a specified water quality around the clock.
Bürkert’s Permeate Monitoring System
Added value for installation engineers and operators in water treatment
✔ Error-free permeate analysis for each pressure pipe ✔ Transparency regarding the state of the diaphragms ✔ Maintenance intervals and costs can be planned ✔ For systems of any size ✔ Digital control options
A compact system for your permeate control
„Is my permeate always of the right quality?” No more need to ask this when you use a Permeate Monitoring System. It automatically monitors the permeate of the individual pressure pipes in reverse osmosis or nanofiltration plants (RO/NF).
Whether for water treatment or seawater desalination, once installed, it provides an accurate overview of small, medium and large installations.
permeate of desired quality
You will receive a Permeate Monitoring System ready to install and pre-configured for your installation. It comes with everything you need for reliable and efficient monitoring of water quality. When connected to the controller (PLC), it ensures your plant is digital. This provides you with all relevant data at a glance at all times and ensures that it is fully documented.
The benefits of the Permeate Monitoring System
Permeate monitoring in practice
A practical example demonstrates the benefits of the system in practice:
A waterworks with 40 pressure pipes has previously sampled and documented permeate quality each day.
The switch to automated Permeate Monitoring System saves nine working hours each month. Annually, 108 hours are saved.
