When designing the filtration system, the designers had initially looked at a system that combined a traditional sand filter with sweeper piping (typical filtration efficiency of 20 microns). Additionally, in order to filter particles less than 5 micron in size, a disposable cartridge filter system needed to be added.
J.D. Sales Company, representing Vortisand, was invited by the contractor to bid on this project. It was immediately apparent that traditional sand filters could not achieve the required level of filtration. The additional use of cartridge filters would require frequent replacement (with additional labor and disposal costs), further increasing the maintenance costs. Due to the size of the particles, conventional centrifugal separators was an ineffective option.
A simple Total Operating Costs (TOC) calculation3 was performed, clearly demonstrating that the Vortisand® system would cost 7 times less to operate than the alternative solution. With an ROI of less than 2 years and substantial savings in operating costs, Vortisand proved to be the best filtration system.
