Dow technology used for sustainable use of wastewater in UAE

Dow-at-Park-Hyatt-Dubai--2Dow showcased its latest water and process solutions technology that has successfully been used in a project in Dubai to reuse wastewater for sustainable operation of cooling towers.

At the heart of this recycling project is DOW membranes technology from Dow Water & Process Solutions, a business unit within The Dow Chemical Company. Dow's membranes filter and process 148,300 cubic meters of water annually for the Hotel that is later used to supply its HVAC (heating, ventilating, and air conditioning) towers which, in turn, help cool the resort’s 225 luxury rooms and suites.

“At Dow, sustainability is at the heart of everything we do and it is always gratifying to see our solutions being used to drive change. Water is a precious resource in the Middle East and it’s important to recognize that wastewater will evolve into the next big source of water along with desalination,” said Dr. Ilham Kadri, Commercial Director, Dow Water & Process Solutions, Europe, Middle East and Africa (EMEA).

The overall system - designed and built by Veolia Water Solutions & Technologies - has helped the hotel save as much as 154,880 cubic meters of potable water since it was launched in 2010.

The system has being used at the Park Hyatt Dubai and it has not only helped the hotel to reduce consumption of potable water, which is such as scarce resource in the region, but also to improve the efficiency of the cooling system.

Waste water effluent from the resort is pretreated using DOW Ultrafiltration membrane technology and is further purified using FILMTEC™ Reverse Osmosis membrane technology from Dow. The process results in high quality water that is low in Total Dissolved Solids (TDS) and not only has an impact on the resort’s environmental footprint but also on the efficiency and cost of the HVAC towers operation.

Dow Water & Process Solutions, through Original Equipment Manufacturer (OEM) Veolia Water Solutions & Technologies, is supplying the ultrafiltration and reverse osmosis components that are processing the wastewater at the resort. Veolia Water Solutions & Technologies was chosen by Park Hyatt Dubai as the contractor for the water recycling project.

“The success of this project demonstrates the viability of water reuse and recycling solutions in a region where water scarcity leads the agenda,” said Emmanuel Gayan Veolia Water Solutions & Technologies Middle-East CEO.
