Cooling water project wins Return on Environment Award

On the seventh of May 2018 the cooling water project of AnQore was rewarded with the Return on Environment Award of Suez. A project of Sitech, Suez and Water Technologies & Solutions and AnQore. The award was granted because of the yearly savings of 376,000 euros on the operational costs, but mainly for the profit this project yields for the environment.

The Return on Environment Award is an initiative of Suez, which has the goal to stimulate new and sustainable techniques for the environment. The cooling water project yearly needs 394,000m3 less retractable canal water and the same amount is saved on the drainage of waste water. Besides this, there has been a saving of 376,000 euros on operational costs, water supply and chemicals. The water balance and the lifespan of cooling systems have been improved, while scale and corrosion are reduced. Wilfried Spierenburg, Energy & Utility Engineer at Sitech: “Also safety has been increased, because operators don’t have to dose or handle chemicals manually.”

PH-neutral phosphate program
The project group decided to switch at GenGard pH-phosphate program for water treatment. This decreases not only the risk at calcium carbonate deposits, but only offers optimal corrosion protection and flexibility when dosing. This helps to play on uncontrollable factors, like the changing quality of the canal water or variations in process conditions. In addition there’s a lower chemistry consumption, less intake of canal water and less discharge of waste water. Finally, with this treatment we no longer speak of degradation or reaction of products, like AMPA.

Continuously measuring and arranging online
Another improvement is the transition to TrueSense online continuous measurement and regulation to react automatically on fluctuations. With the introduction of this measurement- and regulationsystem the water treatment gets regulated 24/7 and can be monitored at a distance. This increases the reliability of the treatment, and the plant will be optimally protected against unwanted consequences of corrosion, deposits or micro biology in the cooling system. Using sensors and online analysis equipment, data gets collected for analyses that could create more insight in the cooling water process. In this way, uncontrolled purging could get traced to work to an optimal high thickening. This ensures less drainage of Meuse water, less discharge of residual water and further reduction of chemistry use.
