SALTY GROUND WATER TO BE CONVERTED INTO A HIGH QUALITY IRRIGATION RESERVE!

The big concern is to convert the salty groundwater to a high quality irrigation reserve in a region that is like a desert!

Well, the Kibbutz Reim is held responsible to convert the salty groundwater to a high quality irrigation reserve in the region that seems like a desert. A massive recovery was necessary to this client, equally for the reason of the limited groundwater amount available and also the challenge of the brine disposal from the inland location.

A flood catchment resource was the source of the feed water and the water had got the high density of the silt, and the variable varies from the 3500 and 7500 ppm TDS and the old corroded pipes that infected the water with the iron.

Iron and the suspended solids were thought to be removed by the pretreatment just before being fed to ReFlex units; however the planned pretreatment system was not at all installed until the years after the systems were on track.

Right after when the units have been in service for a numbers of moths, the pumping from aquifer almost doubled the salinity of the feedwater. The shutdown of the conventional RO systems is because of the lack of the pretreatment and the changes in the quality of the feedwater.

But, the consistent high performance operation was necessary for this critical application. The low energy consumption was made important in addition to the high cost of the power at site.

The ReFlex Max 100 unit was installed by the Desalitech at the site in the month of February 2009 and the ReFlex 150 unit in the month of November 2009. Since then, both are working continuously with the recovery rate of 70 to 93%.

While the fitting of the basic media filtration, crust clean-up frequency go down to the less than once in a year. The ReFlex units now have the strength to adjust to the major quality changes of the feedwater automatically because of the flexibility that is provided by the CCD technology.
