Advanced UV Ballast Water Treatment Systems Work Well for High Flows

When it comes to ballast water treatment, the idea that electrochlorination is more apt a solution for large flows than the UV technology has always persisted. While the earlier generations of UV treatment systems were mostly highly power-intensive and were larger as compared to electrochlorination systems, new solutions such as the PureBallast 3 by Alfa Laval are rapidly changing this conception.

Owing to recent market developments, the UV technology ballast water treatment solutions can now easily compete with advanced electrochlorination systems on the fronts of power and footprint, even when flows as high as 1500–3000 m3/h or even more are taken into consideration. Owing to this, their lower operating costs and simple operations are making consumers rethink their choices. Earlier this year, Alfa Laval signed a contract for supplying several vessels fitted with PureBallast 3 systems for flow capacity of 3000 m3/h.

A large number of shipowners have started realizing the similar power consumption and emission patterns of electrochlorination systems and UV systems. While electrochlorination systems mostly dependent on the temperature and salinity of seawater, meaning that they require considerably more power in conditions such as low temperature and low salinity, advanced UV ballast water treatment systems such as PureBallast 3 are good to work with all varieties of water and are not affected by salinity or temperature.

In terms of form factor, UV ballast systems are smaller than electrochlorination systems and are also less costly and easier when it comes to installation. These factors make UV ballast systems compelling as compared to electrochlorination systems.
