Alstom teams up with Atlantium for invasive species prevention technology

Global manufacturer Alstom has signed a bilateral agreement with Israel’s Atlantium Technologies Ltd. to expand the use of an ultraviolet (UV) ray water treatment process in its hydropower equipment.

The technique “destroys microorganisms the proliferate in the auxiliary water circuits of hydropower equipment,” Alstom said in a release, including balance-of-plant and cooling systems. The company said the problem is particularly serious in North America, where the organismas can slow water flow or even block pipes.

“To solve the problem, Atlantium has developed an innovative water treatment technique involving ultraviolet rays used especially in the pharmaceuticals and chemicals industries,” Alstom said.

The UV rays are diffused by a lamp embedded in Plexiglass tubes and prevent microorganisms and other invasive species from reproducing.

“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,” said Jacques Hardelay, Senior Vice President for Alstom Renewable Energies.

The system is advantageous in that it does not use chlorine or other chemicals, and is easy to maintain.

“We are very proud to be part of the integral solutions for the power industry offered by a leading market player such as Alstom,” Atlantium president and CEO 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.”

Atlantium said in a white paper released in September 2013 that the use of UV technology, which the company called “Hydro Optic Disinfection” (HOD), showed promising results in controlling zebra and quagga mussel populations on dams and hydroelectric power projects.
