Water treatment system with new technology
Processing demineralised seawater
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. Before that, acceptance testing on two new high-speed filling lines was completed in the spring of 2022.
Makkah Water Company began operations and production in 1975. The main plant in Jeddah now has seven complete lines from Krones up and running. In its second plant, Al Janoub in the city of Gizan in southern Saudi Arabia, Makkah Water is still working with mix-and-match lines that include a variety of blow moulders, fillers, and labellers from Krones. Whereas the Jeddah plant produces Safa water, the Gizan plant is focused on the Mozn brand.
In this project phase, Makkah Water had the existing wet end of an 81,000 bph line replaced with an ErgoBloc L. Later in the update project, the company then decided to swap out two more existing lines for Krones systems. Each of the three ErgoBloc L lines fills still table water at 81,000 containers per hour.
Treating demineralised seawater
The water treatment system is among the largest of its kind that Krones has built to date, rated at three times 110 m3/h. The system, which actually comprises three units, each equipped with ultrafiltration, reverse osmosis, and electro-deionisation, processes demineralised seawater. With the new electro-deionisation (EDI) module, whose debut installation is this one at Makkah Water, the result is ultrapure, deionised 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 remineralisation and ozonisation: The Hydronomic MDS mineral-dosing station uses a mass flow meter to deliver precise quantities of various minerals. The Hydronomic OZ water ozonisation system stabilises 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.
