  • Patent number: 10753853
    Abstract: A method of evaluating the corrosion resistance of a coated metal substrate, the method including putting a liquid composition into contact with a corrosion protection coating present on the surface of a metal substrate, the liquid composition including water, a gelling agent, corrosion-catalyst ions, and a color pH indicator; gelling the liquid composition in order to form a corrosion-accelerator gel in contact with the coating; performing a corrosion test during which the gel that has formed is left in contact with the corrosion protection coating; and evaluating the corrosion resistance of the substrate coated by the corrosion protection coating by observing the color of the color pH indicator present in the gel after performing the corrosion test.
    Type: Grant

  • Patent number: 7473365
    Abstract: The biological water or wastewater treatment process described herein alternates aeration and anoxic phases during a water treatment process. According to one exemplary process, the water or wastewater is directed into a biological tank. The water or wastewater in the biological tank is aerated until measured nitrate or redox values meet high nitrate or high redox set value conditions relative to minimum aeration and maximum aeration time requirements. Subsequently, the water or wastewater is subjected to anoxic treatment until the measured nitrate value meets low nitrate set value conditions relative minimum and maximum anoxia time requirements.
