Desalination RO plant performance improved by using Pursanova Disk
In a lot of parts in the world, water is very difficult to come by. The water even out of bore wells has to be treated before it is possible to use as drinking water. Especially bore well water in dessert area or where the ground water is heavily used the TDS content of the water can be very high.|
In a lot of cases reverse osmosis is used to reduce the TDS out of the borewell water and get a somehow acceptable drinking water.
A Saudi Arabian company runs several RO Systems to produce drinking water.
So the experience from the customer has been they have to replace the sediment filter once a week and each and every membrane in all their RO systems, in less than 3 months.
|In order to extend the time of replacement of a membrane, it is common to add a cocktail of chemicals, to slow down the fouling. Stopping the fouling totally can hardly be achieved by using chemicals. PursanovaTMDisk has been installed at this RO System, where the membranes have been already partialy blocked. It could be seen immediately, the daily decline of the production of water stopped after the installation of Pursanova DiskTM, it even increased to some extend over time. Recognizing stable results over some weeks, a customer stopped totally adding chemicals to the system. Having stable results for more than a year, where no fouling of membrane happened and no replacement has to be done, the customer decided to add to all his RO Systems Pursanova DiskTM.|| |
The return of investment ROI in-case has been less than 2 months. Not only there are no chemicals needed anymore, the production is stable on the same high level, there is no shut down of production for replacement of some parts of the RO, and of course, the lifetime of the membrane itself is far higher. As well the need for electricity in the pumps is reduced, due to the fact there is no fouling of the RO Membrane anymore there is less pressure needed to press the water through them.
