Reverse Osmosis Performance Evaluation

Reverse osmosis performance evaluation

Reverse osmosis systems shall be periodically monitored on several parameters which are also considered during the design of the reverse osmosis system :

Feed pressure
Permeate pressure
Concentrate pressure
Feed conductivity
Permeate conductivity
Feed flow
Permeate flow
Temperature

Lenntech systems are equipped with the necessary instrumentation that measures quality, flow, pressure and other data like temperature. This will allow to easily and effectively monitor the performance of the RO system and identify early stage symptoms, for better maintenance and extended life time of the RO system and membranes.

Lenntech systems calculate different performance indicators which will help to evaluate the performance of RO and to identify anomalies and help troubleshooting: Recovery, Salt rejection, Salt passage and mass balance. With these indicators, Lenntech can advise the customer to perform maintenance, cleanings or replacement of membranes.

Parameters affecting RO performance

The key performance parameters of a reverse osmosis system are the permeate flux and salt rejection.

A membrane system should be designed such that each element of the system operates within a frame of recommended operating conditions to minimize the fouling rate and to minimize mechanical damage.

One of the parameters that makes part of membrane manufacturers recommendation values is the permeate flux. The flux is the rate of permeate transported per unit of membrane area.

Systems operating on high quality feed waters are typically designed at high flux values, while systems operating on poor quality feed waters are designed at low flux rates.

Lenntech designs its systems according to the limits recommended by the manufacturer, in order to increase membrane life time and minimize troubles in the system.

Lenntech provides sustainable and complete solutions with RO technology, integrating it with the pre-treatment and post treatment necessary.
