Water scarcity accelerates the need for desalination - "More and more desalination plants are being built"

There is an acute shortage of clean water. Half of the world's people suffer severe water shortages for at least a month every year. Climate change, population growth and urbanisation are exacerbating the water shortage.

Desalination allows seawater to be turned into drinking water. Finnchain is an important part of technology development and implementation.

- More and more desalination plants are being built. By all forecasts, the need is only increasing and we have the capacity to meet this demand. Our scrapers are ideally suited for the pre-treatment process step of removing solid, organic or oily matter from seawater," says Gerald Dippacher, Sales Manager.

Desalination technology is evolving rapidly

According to the UN, clean water is essential for health, poverty reduction, food security, peace, human rights, ecosystems and education. The UN has therefore made clean water one of its top sustainable development goals.

At the same time, desalination technology is evolving rapidly. This makes desalination more affordable. Seawater is being turned into potable water, particularly in the Middle East and Africa. Finnchain has supplied schematic systems for desalination plants in Saudi Arabia and Algeria.

- Our scrapers are part of the pre-treatment process, where air is pressurised into the tank. When the air is released as bubbles, it raises the organic matter to the surface as foam. The scrapers remove the foam from the seawater to prevent organic matter from clogging the reverse osmosis membranes. This would complicate the step of removing the salt itself.

There are many good reasons to choose Finnchain scrapers for a desalination plant. In addition to the advantages related to the design of the components, there are several strong trump cards.

- We are able to use alternative materials such as special steels and plastic parts. In addition, we have a rail irrigation system that reduces friction between the components of the scraper, as the surface of the scraper is mostly above the water surface to be treated," explains Dippacher.

Finnchain scrapers remove organic matter from seawater, which facilitates desalination.
