Powerful water treatment system with new technology
The Saudi-Arabian drinking-water producer Makkah Water Company has, for now, finished updating and expanding capacity at its main plant in Jeddah. The new, high-performance water treatment system from Krones passed final acceptance testing in October 2022. The water treatment system is among the largest of its kind that Krones has built to date, rated at three times 110 cubic meters per hour. The system, which actually comprises three units, each equipped with ultrafiltration, reverse osmosis, and electrodeionization, processes demineralized seawater. With the new electrodeionization (EDI) module, whose debut installation is this one at Makkah Water, the result is ultrapure, deionized water to which the desired minerals can then be added. The addition of the EDI module is especially important for producing still table water whose mineral content has no tolerance for deviation, as is the case at Makkah Water. In addition, the scope of supply also included an activated-carbon filter and modules for remineralization and ozonization: The Hydronomic MDS mineral-dosing station uses a mass flow meter to deliver highly precise quantities of various minerals. The Hydronomic OZ water ozonization system stabilizes the product microbiologically prior to filling. "The new water treatment system replaced our existing equipment. Installation and commissioning went according to plan," explains owner Sheikh Ali. "For this water treatment project, we chose to work with Krones based on the new technology and our long and excellent partnership – and that has so far served us well," he explains.
