@Evoqua's Vortisand helps cool Dubai's Mercato Shopping Mall

MONTREAL & PITTSBURGH--(BUSINESS WIRE)--Evoqua today announced its Vortisand® water filtration system is helping to keep the Dubai Mercato shopping center cool and comfortable for the thousands of shoppers who visit the mall.

Evoqua was selected to supply a 150 gallon per minute (gpm) Vortisand cross-flow microsand media filtration system to filter the water circulating in the shopping mall’s cooling system. The location of Mercato poses a unique challenge--being located near the beach makes the rooftop cooling tower susceptible to strong winds along with debris and sand. The water used in the cooling towers continuously contacts these airborne particulate contaminants. Typically, more than 85 percent of suspended solids in condenser cooling tower water are smaller than 5 microns, which are too small to be effectively removed using conventional media filtration. Studies have shown that these fine particles are the adherent contaminants that foul the entire water loop system (including downstream equipment). Removal of the fine particles ensures the cooling system operates as designed and at peak efficiency, reducing energy consumption and maintenance costs. It is important to note that these wet environments aid in promoting various forms of bacteria growth, such as Legionella. Both filtration and disinfection methods can help in reducing bacteria growth.

Mercato’s water treatment system previously included over-sized side stream filtration pumps with a centrifugal separator. The routine maintenance activities were made up of cleaning of the cooling towers every month and cleaning of the chiller tubes every 12 months. Mercato required a high efficiency media filter that has the capabilities of removing fine solids, yielding decreased total operating and maintenance costs.

The Vortisand system is unique in its high efficiency capabilities and reduced footprint, making it the perfect solution for the Dubai Mercato shopping mall. The natural outdoor environment posed a challenge; over time, the cooling tower acted as an air scrubber, absorbing mainly sand and dust. As discussed above, such debris will decrease the cooling systems efficiencies, while increasing both maintenance and operational costs. Most importantly, Mercato requires a cooling system that is working at peak performance 24/7, making it comfortable for guests and employees. The cross-flow technology coupled with microsand media expands the system’s filtration capabilities, enabling the system to deliver submicron filtration performance. Being sized to 1/3rd of the original system’s footprint allowed for reduced pump and energy costs. The system’s configuration and design is unique in that it uses filtered water for backwash, resulting in a more sustainable and green solution, while offering further savings in water consumption.

Due to its individual and unequalled ambience, Mercato is one of Dubai’s most charismatic and best-loved shopping malls. Although Mercato is essentially a community mall, serving the needs of residents in Jumeirah and surrounding areas, it also attracts tens of thousands of tourists from all over the world every year. Spanning 643,067 square feet, Mercato is home to over 140 shops and outlets. The mall prides itself in offering customers a superb variety of international fashion and lifestyle brands, while serving a comprehensive selection of mouth-watering cafes and restaurants.

Among all the technologies being evaluated, the Vortisand ® system was the one that made the strongest case for increased efficiency and reduced operational cost. They have not only demonstrated deep application knowledge, but also backed their claim by delivering a high-quality and easy-to-retrofit product.” – Edwin D’souza, Head of Engineering & Maintenance
