Alstom has signed a bilateral agreement with Israel-based Atlantium Technologies to expand the use of a new water treatment solution in hydropower equipment.

The technique uses ultraviolet rays (UV) to demolish microorganisms that reproduce in the auxiliary water circuits of hydropower equipment such as balance of plant, cooling systems and several others.

Invasive aquatic species such as algae, mussels, bacteria cause a severe problem for the hydropower industry, especially in the American continent.

They can slow the water flow in installations or even block pipes, resulting in costly maintenance.

Atlantium has developed a new water treatment technique to solve the problem. It uses UV rays, normally used in the pharmaceuticals and chemicals industries, which are diffused by a lamp embedded in Plexiglas tubes and prevents the invasive species from reproducing.

Alstom said UV rays are totally environmentally friendly when compared to other water treatments like chlorine or ozone. The technique needs little initial investment and is easy to maintain.

Alstom Renewable Energies senior vice president for hydro Jacques Hardelay said: "With this agreement, Alstom will enable its customers to benefit from an innovative, low-cost, environmentally respectful technique that has already proven itself in other industries and consolidates its position as the leader in services provision in the hydropower market."

Atlantium CEO and president Benjamin Khan said: "This collaboration will provide Alstom’s customers with a unique, chemical-free and field-proven solution for their mussels and macro-fouling challenges."
