Cooling water project wins Return on Environment award

On May 7, 2018, the cooling water project at AnQore was rewarded with the Suez Return on Environment award. A project from Sitech, Suez Water Technologies & Solutions and AnQore. The award was granted because of the annual savings of € 376,000 on operational costs, but above all  the profit this project brings to the environment.

The Return on Environment award is an initiative of Suez that aims to stimulate the use of new and sustainable techniques for the environment. With the cooling water project, 394,000 m3 less drainage of canal water is required annually and the same amount is saved on the discharge of waste water. In addition, savings of € 376,000 were realized on operational costs, supply of water and chemicals. The water balance and the lifespan of the cooling system are improved, while the scale and corrosion are reduced.

Wilfried Spierenburg, Energy & Utility Engineer at Sitech:

“Safety has also increased, because operators no longer have to manually dose or handle chemicals”.

pH-neutral phosphate program
The project team decided to switch to GenGard ™ pH phosphate program for water treatment. This not only reduces the risk of calcium carbonate deposits, but also offers optimum corrosion protection and flexibility in dosing. This helps to respond to uncontrollable factors, such as the changing quality of the canal water or variations in process conditions. In addition, there is lower chemical consumption, less intake of canal water and less discharge of waste water. Finally, there is no degradation or reaction products, such as AMPA.

Continuously online measurement and control system
Another improvement was the transition from periodic manual monitoring to TrueSense ™ online continuous measurement and control to respond to fluctuations automatically - so faster. With the introduction of this measurement and control system, the water treatment is controlled 24/7 and monitored from a distance. This increases the reliability of the treatment, so that the factory is optimally protected against undesirable effects of corrosion, deposits or microbiology in the cooling system. Using sensors and online analyzing equipment, data is collected to carry out analyzes that create more insight into the entire cooling water process. In this way, uncontrolled pumping losses can be detected in order to work towards an optimal high thickening. This, in turn, reduces the intake of Meuse water, reduces wastewater discharge and further reduces chemical consumption.
