Client’s need

The gas turbine at the test power station has an output of up to 500 megawatt. The necessary cooling of the air intake for the turbine part of the gas turbine is achieved by a water steam circuit.

The silica content must not be higher than 20 ppb, otherwise deposits could form and cause damage to the sensitive heat exchanger. For this purpose, the in-plant water treatment plant produces ultrapure water.

When the water treatment plant needed to be modernised the customer ordered a Veolia Mobile Water Services treatment plant for five weeks. This temporary solution had to supply two tanks with 1,700 m³ volume each with a constant supply of demineralised water.

Our solution

A MORO-25C container with Reverse Osmosis pre-treatment and a MODI- 15000T trailer with a mixed media polisher and a pressure booster station with 100 m³/h, 6 bar were supplied.

The MORO system removed around 98% of the feed water impurities and contamination and the MODI with its ion exchangers then demineralised the water to achieve the desired quality.
