Inge's Large Scale Water Treatment Expertise Projects from Around The Globe

Ultrafiltration technology in major projects: inge® showcases its water treatment expertise with examples of large scale projects across the globe!

The following reference projects are just a selection of the company’s recent achievements.

Accra, Ghana (Africa)

One of inge®’s first international lighthouse projects in the sea water treatment sector

Huge quantities of drinking water are required for the metropolitan area of the Ghanaian capital Accra. To meet these needs, a cutting-edge sea water desalination plant was officially opened about two years ago in Nungua Township, some 12 kilometers from Accra.

The plant uses reverse osmosis (RO) to produce 60,000 cubic meters of drinking water a day for around 500,000 people. Following a rigorous selection process, the plant contractor chose inge® to equip the plant with 10 UF lines as a pretreatment stage for RO.

As well as specifying top-quality UF technology, consulting expertise, and engineering services at the planning stage, the client also expressly requested an expanded package of services for this project. In response, inge® offered not only its high-performance ultrafiltration racks with their patented Multibore® membrane fibers, but also the central header pipes, valve units, local instrumentation and assembly of the UF lines. This full package bid proved to be enough to secure the contract.

Despite the fact that the quality of the feedwater turned out to be significantly lower than the figures stated in the tender, the UF system has been successfully supplying 135,000 cubic meters a day (35.7 MGD) of pre-filtered water to the RO stage ever since, helping to turn sea water into clean drinking water for the local population.

Jamnagar in India

inge® UF system for the biggest sea water desalination plant in the company’s history

This mega project in the Indian city of Jamnagar was a genuine milestone in inge®’s corporate history. It involved the biggest sea water desalination plant that inge® had ever equipped with its membrane technology. Built by the contractor IDE Technologies, the plant supplies process water to one of the world’s largest refinery complexes in Jamnagar, which is situated in the Indian state of Gujarat. inge® supplied the UF modules used as a pretreatment stage for reverse osmosis (RO) in the sea water desalination process.

Over 4,000 T-Rack® 3.0 modules went online in April 2017. Since then, they have been supplying 456 million liters (120 MGD) of pre-cleaned water a day to the RO units. The inge® UF pretreatment stage significantly improves the quality of the sea water that is treated using conventional pre-cleaning methods. The UF modules play a major role in protecting the highly sensitive reverse osmosis membranes.

inge® initially installed a pilot system on-site to prove that its modules could comfortably fulfill the customers demanding standards for the UF system. Even during the monsoon season, when the water was particularly challenging, the UF module still met the targets for process stability, filtrate quality and yield. What’s more, the T-Rack® 3.0 concept satisfied all the customer’s requirements regarding a compact and space-saving design. During the execution of the project, inge® provided top-notch technical support for the entire UF system in collaboration with the plant contractor.

TUAS III – Singapore

Drinking water from the ocean for a country without a ready supply of fresh water

Another mega-project that offers a striking example of inge® technology in the Southeast Asia region is TUAS III in Singapore. The island city-state has no fresh water reserves of its own and is therefore entirely reliant on alternative sources of drinking water. As well as rainwater collection, these sources include cleaned and recycled water, imported water and seawater desalination.

This latter option already makes up one quarter of Singapore’s water supplies and is steadily gaining in importance. Since 2005, the country has had the technology in place to secure enough water for its more than 5.5 million citizens, and by 2060 it hopes to cover 30 percent of its water requirements with sea water desalination.

The new sea water desalination plant TUAS III is currently under construction and is scheduled to come online by the end of 2017. inge GmbH is supplying the UF system to pretreat 289,000 cubic meters a day (76.6 MGD) of pre-filtered water for the subsequent reverse osmosis stage.

This is the first sea water desalination plant in Singapore that will be run directly by the national water agency PUB. The end customer has therefore insisted on the highest standards of quality for all the system components. As well as supplying the UF technology, inge® also provides extensive technical support to ensure all the customer’s requirements are met.
