In 2016: PET line with water treatment
In its facility in Qassim Al Jomaih fills the still water Aquafina in 330-, 600- and 1,500-millilitre PET containers. To match this facility’s capacities to the ongoing level of demand, Al Jomaih installed yet another PET line there, rated at 40,500 containers an hour with reference to the 600-millilitre bottle. The heart of this line is a blow-moulder/filler block, featuring a Contiform S stretch blow moulder and a Modulfill VFJ filler. To comply with the Aquafina standard, the latter is in maximally stringent hygienic design, with a foam cleaning feature and a cleanroom. The block also includes a PreformCheck inspector, plus a Prejet preform rinser. This means Al Jomaih can do without a bottle rinser. The containers are dressed on a Contiroll HS labeller in ergonomic design, which has been linked up to a multiple reel magazine to save the operators quite a lot of time. What’s rather intriguing is the packer model installed – the Variopac Pro WT-FS machine is able to produce a most varied range of end-of-the-line packages: whether it’s just film, trays wrapped in film, pads with film or wrap-around cartons. And last but not least, the packages are loaded onto pallets by a single-column Modulpal 2A palletiser.
For water treatment, Al Jomaih has opted for a new Hydronomic RO from Krones, rated at 27 cubic metres an hour. In this system, specially modified for Aquafina, the raw water is set to a residual salt content of less than two milligrams per litre of TDS (total dissolved solids) using an activated-carbon filter and two permeate-graduated reverse osmosis systems. This figure lies far below the customary residual salt content after treatment in reverse osmosis systems. After that, the permeate is remineralised and then ozonised.
Krones installed the line as a turnkey job, with platforms for control cabinets, air-conditioning equipment, transformer station and the interface to the water treatment system. It was precisely this unique combination of filling and water treatment kit from a single source that for Al Jomaih constituted an irresistible inducement to place the order with Krones.
