Al Marjan island chooses Atlas Copco air blower to enhance sustainable wastewater treatment
Al Marjan Island is one of the most beautiful tourism attraction in UAE and the Arabian Gulf region, with group of four coral-shaped islands in a man-made archipelago located in Ras al-Khaimah, one of the seven emirates of UAE blessed with beautiful coastline and amazing red desert. Al Marjan island is home of many luxurious holiday resorts that attract 250,000 tourists every year making it one of the must go destinations for visitors to Emirate of Ras Al Khaimah.
The island is served by a dedicated sewage treatment plant that is designed to a capacity of 2000 m3/day, where availability of 24/7 wastewater treatment service is crucial. Air blowers form an integral part of wastewater treatment process as compressed air is used for aeration of wastewater. Air blowers that produce compressed air consume almost 70% of the total energy consumed by the wastewater plant.
Al Marjan Island puts sustainability and lowering carbon footprint as cornerstone of their vision and mission, accordingly Al Marjan Island’s team jointly with Atlas Copco conducted a study to reduce carbon footprint and enhance plant reliability and blowers were one of the prime assets which the team jointly analyzed.
Efficiency of screw technology
The ZS75VSD with onboard variable speed drive provides the system with unmatched turn down and linear synchronization with the aeration tank dissolved oxygen analyzer to deliver air exactly matched with the demand of the wastewater process eliminates energy waste and owing to the internal compression of the screw technology and directly coupled motor ensures lowest specific energy per unit of air produced.
Reliability matters a lot!
The ZS screw blowers being gear driven blower with forced lubrication and complete onboard oil system that includes cooling and filtration results in a much reliable blower.
Typical service interval is increased to 4000 hours from 1000 hours maintenance intervention required on a traditional roots’ blower in high ambient conditions of the Middle East. Oil change on ZS screw blowers is made only at 16,000 hours unlike a few thousand hours for a roots blower.
