WEG’s Electric Motor Solutions are Adopted in Desalination Plant in Singapore
[ad_1]
There is no doubt that one of the major water problems facing the world today is the provision of drinking water. Water scarcity was listed in 2019 as one of the biggest global risks in terms of potential impact over the next decades.
Through a team of engineering specialists dedicated in the Water Industry, WEG has always been at the forefront of supplying electrical solutions for the Water Industry worldwide. This time WEG products are chosen as part of the Keppel Marina East Desalination Plant (KMEDP) project in Singapore. In this specific project, WEG’s motors are installed in it.
The KMEDP is an innovative large-scale desalination facility; and is also the world’s first dual-mode desalination plant. Its innovative capability can treat both freshwater and seawater, depending on weather conditions. The plant will produce 137.000 m3/day of clean water, which is enough to fill 45 olympic-size swimming pools and 7 percent of Singapore’s daily water demand.
For this project, WEG Singapore collaborate with Torishima, a pioneer in pumps for seawater desalination, to supply the high efficiency motors for their Reverse Osmosis (RO) system package.
In desalination systems, from small to large capacities, energy savings is always concern, it’s usual therefore, to consider energy recovery devices (ERD) to achieve best operation conditions and high energy savings. This device combined with the ERD Booster pumps and high-pressure pumps will drive cost savings and emission reductions.
There are two types of pumps used in RO system High Pressure Pump and ERD Booster Pump.
The WEG’s motors scope of supply from Nantong Factory was:
- 8 units of W60 2050 kW, 6.6 kV motor, 2 poles, B3 for 1st Pass RO High Pressure pumps
- 8 units of W21 160 kW, 400 V motor, 2 poles, B3 for ERD booster pumps
Motors for the use in desalination plants are required to operate in harsh climates 24/7, highly durable, with special painting plant against corrosion from seawater and high efficiency to minimize energy consumption.
WEG is very proud to be part of the Keppel Marina East Desalination Plant project, with the supply of special designed products to attend customers’ needs. This project is another WEG step towards Water Industry and Driving Efficiency and Sustainability.

WEG provides solutions for desalination plant in Spain
[ad_1]
WEG has partnered with Sacyr Industrial to provide essential equipment and support the expansion of a largescale seawater desalination plant in Tenerife. The project, completed through WEG subsidiary, WEG AUTRIAL, has increased the desalinated water production capacity of the site by 37 per cent, increasing its potential supply to 24,000 more households than before.
Desalination describes the removal of salt from seawater to produce clean drinking water. This process is crucial for countries that have coastlines but have no readily available fresh water source. Canary Islands, such as Tenerife, are an example of where these operations are necessary.
The plant came into operation in 2001 but has undertaken a remodelling plan to better support the population of Tenerife. The remodelling project, managed by Sacyr Industrial and operated by Valoriza Agua, has enabled a colossal 28,800 cubic metres of water to be desalinated each day. This is a 37 per cent increase in capacity compared to the previous 21,000 cubic metres per day.
To support the remodelling project, WEG was approached to supply industrial power equipment to ensure the plant’s operations. Services included the installation of medium and low voltage electrical equipment, the installation of new Motor Control Centres (MCCs), plus the supply and installation of low voltage drives. This included the addition of 20 CFW11 variable speed drives (VSDs).
“WEG has a wealth of experience in suppling industrial equipment for harsh environments”, explained Javier De La Morena Cancela at WEG Spain. “For applications like the desalination plant in Tenerife, it was crucial that all suppliers are well versed in the complexities and challenges of installing equipment that can operate in saline conditions.”
“For this application, it was essential for the equipment to be robust, reliable and able to withstand the environment. Crucially, it was also imperative that the equipment is as energy efficient as possible as one of the core goals of the project was to reduce the emissions of the entire plant.”
“In addition to increasing production, the remodelling carried out by Sacyr have made it possible to increase the energy efficiency of the installation”, explained Paula Soriano, manager of the Empresa Mixta de Aguas de Santa Cruz de Tenerife (EMMASA), entity that manages the desalination plant in Santa Cruz de Tenerife. “[The remodelling is] achieving a reduction of emissions into the atmosphere of the environment of two million kilograms of CO2 per year, which is equivalent to the emissions of more than 1,700 new vehicles per year.”
The project has dramatically increased the conversion in the desalination plant, reducing the sea water needed to obtain the same amount of drinking water by 7,300 cubic metres per day. This volume is equivalent to almost four Olympic-size swimming pools a day.

WEG, new member of the Latin American Association for Desalination and Water Reuse (ALADYR)
[ad_1]
WEG, one of the largest manufacturers of electro-electronic equipment in the world, with headquarters in Brazil, has joined the Latin American Association for Desalination and Water Reuse (ALADYR) as a new member. The company’s goal is to continue growing in the water sector with partners who promote and expand desalination and reuse as real options to achieve universal access to drinking water for all
ALADYR is a non-profit trade association, the most important reference in Latin America in terms of desalination, reuse and treatment of water and effluents. Founded in November 2010, within the framework of the II International Desalination Seminar in the city of Antofagasta, Chile, the association fosters the development, promotion and gathering of timely knowledge on technologies for desalination, reuse and treatment of water and effluents, based on the provision of information exchange spaces that promote strategic alliances, projects and initiatives aimed at guaranteeing access to drinking water in Latin America under standards of sustainability, efficiency and social future.
As the main player, WEG provides the water sector with the most efficient and profitable electrical solutions, also working on the most demanding projects and works in energy efficiency around the world. Our knowledge and cutting-edge technologies guarantee the best electrical design when engineers and operators want to guarantee high levels of efficiency and low operating costs in their plants and processes. With more than 1,200 service centers around the world, WEG has the experience and capability to offer local support on five continents.
This new milestone in the water business line coincides with the launch of the WEG Motor Specialist, a Motion Fleet Management asset management software module that, through artificial intelligence and Machine Learning, performs automatic fault diagnoses, such as imbalance or misalignment. of electric motors, as well as load and consumption indicators. This new system works on water treatment infrastructures, helping in the operation and maintenance of plants and optimizing asset management.
With this new participation in ALADYR, WEG wish to continue providing solutions for the water sector in Latin America, and collaborate with other partners to improve water supply throughout the region.
