PUMPS, VALVES & ACTUATORS PUMPS HELP PURIFY SEAWATER boost reliability.
The Shuqaiq 3 desalination plant on Saudi Arabia’s Red Sea coast is being built by a public private partnership between the Saudi government and an international consortium. The Spanish water engineering specialist, Acciona, is responsible for the design and construction of the plant. When complete, the plant will produce 450’000 cubic meters (99 million gallons) of clean water per day, supplying the nearby cities of Jizan and Abha with a potential population of 2 million inhabitants.

ENERGY-SAVING PUMP/BLOWER OPTIMISATION
Detection Services, the largest specialised water management business across Australia and New Zealand, has signed a key agreement to introduce energy-saving pump/blower optimisation products and services from UK company Riventa. Detection Services offers multi-discipline pipeline solutions and technologies covering the water and wastewater industries, and operates from eight different locations, including Perth, Auckland and Brisbane. Chris Evans, general manager at Detection Services, said: “Riventa’s expertise further strengthens our
commitment to extending the life of assets and the partnerships we develop with our customers. This new agreement will help us continue to deliver knowledge and insight that reduces risk and improves reliability and sustainability.” Riventa’s managing director, Steve Barrett, added: “Detection Services have an excellent track record
in Australasia for providing innovative solutions in water and wastewater applications, so we look forward to working together on showing what we can add with the considerable energy-saving measures that we have to offer.” Meanwhile in India, Autoflow Engineers & Controls is also introducing Riventa’s pump/blower
technology to its home nation. Covering the three western Indian states of Maharashtra, Goa and Gujarat, Autoflow offers turnkey automation and remote monitoring solutions to a growing market. Mahesh Salunke, managing director at Autoflow Engineers & Controls, said: “Apart from water and
wastewater treatment plants, we work with several other industries where Riventa will add significant value to our services...” Commenting on the agreement, Barrett said: “We see great
potential in this region of India. Autoflow Engineers & Controls has an excellent pedigree in the applications where our optimisation products and services can make a big difference to the bottom line and the long-term wellbeing of water and wastewater treatment plants.” Riventa has also teamed up with Toraqua Technologies in
Brazil. Riventa

12 MARCH 2021 | PROCESS & CONTROL
Purifying seawater to produce potable water using RO requires the saltwater to pass through a filtration membrane, and the energy associated with the pumps required for this process make up a significant proportion of the total costs. To achieve the maximum possible energy efficiency in the design of Shuqaiq 3, Acciona engaged the expertise of Sulzer’s Desalination Competence Center, based in Madrid, at the outset of the project. Typically, the high pressure pumps used to run large individual RO trains operate at around 87-88 percent efficiency. Instead of the typical configuration, where one pump supplies each RO train, by using a smaller number of larger pumps, with each unit supplying trains (in normal operation) through a manifold; an efficiency increase leads to values over 90%. The competitive tender that was awarded to Sulzer included the seven high pressure HPDM pumps. The contract also included 46 additional pumps to perform various critical roles across the plant, including seawater intake pumps, intermediate booster pumps, high pressure booster pumps and potable water pumps.
All the pumps underwent a comprehensive test regime before being dispatched to Saudi Arabia. In these tests, the critical HPDM pumps demonstrated efficiency of over 90 percent, comfortably meeting their specification and validating the benefits of the innovative design delivered by Sulzer. Construction of Shuqaiq 3 is expected to be completed at the end of 2021.
