It should be remembered that, in the industrial world, the term "Revamping" means the modernization of any system, through modifications, aimed at restoring or even improving its original performance.
Since water treatment plants have always been considered simple "utilities", as machines enslaved to the "process and production" plants, it is difficult to invest economic resources for their efficiency.
In truth, not everyone knows that, with a minimum investment and some minimally invasive modifications, it is possible, for example, to revamp an old and obsolete ion exchange demineralization system, conventionally regenerated in Co-current, transforming it into a Compact Bed demi system, simply by inverting the flows of regenerants and using, inside the columns, special resins with monodisperse sceensize or with homogeneous diameter.
As already pointed out, the modifications are not very invasive and allow the retrofitting of an old plant, allowing to obtain significant benefits and gains in terms of operating costs, as reported below:
• increase operating exchange capacity of the installed resin 25-30%;
• regenerants consumption reduction 30-50%;
• increase cycle production between two regenerations 100%;
• treated water better quality;
• reduction of rinse water consumption;
• regeneration eluates reduction volume 50%;
• increasing resin organic fouling resistance.
For those interested in deepening a specific case study, below we provide a Data Collection Technical Sheet that we invite you to fill in, aimed at collecting all the functional parameters of your system, to allow us to help you evaluate any ravamping feasibility study.
