DuPont Water Solutions offered technical assistance to the Safi plant in Ajman to install and manage the system, which produces low conductivity water for the production facilities and helps provide fresh water to the water-scarce region.
“This project aligns with the UAE vision 2021 to preserve water resources, as well as improves the quality of air, increases the contribution of clean energy and implements green growth plants,” said Gurvan Dersel, general manager at Safi Water.
Constructed in 2010 and then extended with DuPont technology in 2016, the Safi plant was designed to desalinate estuary water as a means to reduce stress on fresh water resources in the region. The extended plant employs a two-stage system that first utilizes IntegraPac IP-77-XP Ultrafiltration (UF) for pretreatment of the water. Then, FILMTEC BW30XFR-400/34 Reverse Osmosis elements – a spiral wound, fouling resistant membrane for brackish water – are employed for the second stage.
Process data via DuPont’s innovative, proprietary software, WAVE, shows how the pre-treatment stage in the system minimizes membrane fouling, which in turn lowers required system feed pressure and the need for frequent membrane cleanings. In addition, the duel-stage approach reduces not only capital investments and operating costs, but also the environmental footprint of the plant.
“The water table of the UAE has dropped about one meter per year for the past 30 years, a rate that would deplete its natural freshwater resources in about fifty years. It is therefore critical for this region to take steps that ensure long-term sustainable water management,” said HP Nanda, global VP and general manager – Water at DuPont.
“This tremendous honor further validates the cutting-edge work of the entire Safi Water team and highlights the success of this integrated treatment approach to help the industry solve these pivotal resource challenges and improve the efficiency of water management around the globe.”
