Abstract: A method for reducing recalcitrant chemical oxygen demand (COD) of a liquid in a water system is provided. The method comprises pretreating the liquid in a pretreatment unit (12) to remove indigenous bacteria or microbes to a population level below which the indigenous organisms can interfere with the screened and externally introduced microorganisms. The liquid is then provided to a reactor (20) that has a filter bed (22) formed with a carrier material (26). Special microbes are screened and used to colonize the carrier material (26) to remove recalcitrant COD. A biofilm is cultured on the surface of the carrier material (26) to immobilize the screened microbes in the reactor (20). The method further comprises adding a co-substrate as the liquid enters the reactor (20) and percolating the liquid through the filter bed (22) colonized with the screened microbes to degrade at least part of the recalcitrant COD under aerobic conditions. The screened microbes comprise at least one microbial species selected from the group consisting of Bacillus, Comamonas, Arthrobacter, Micrococcus, Pseudomonas, Pediococcus, Achromobacter, Flavobacterium, Mycobacterium, Rhodanobacter, Stenotrophomonas and yeast.

Abstract: A method for selective aluminide diffusion coating removal. The method includes diffusing aluminum into a substrate surface of a component to form a diffusion coating. The diffusion coating includes an aluminum-infused additive layer and an interdiffusion zone. The diffusion coating is solution heat treated at a temperature and for a time sufficient to dissolve at least a portion of the interdiffusion zone. Thereafter the aluminum-infused additive layer is selectively removed. An aluminide diffusion coated turbine component is also disclosed.

Abstract: A rotor blade for a turbine of a gas turbine includes an airfoil. The airfoil may have a leading edge, a trailing edge, an outboard, and an inboard end that attaches to a root configured to couple the rotor blade to a rotor disc. The airfoil may have a cooling configuration that includes elongated cooling channels for receiving and directing a coolant through the airfoil. The rotor blade may further include: a tip shroud connected to the airfoil; outlet ports formed through an outboard face of the tip shroud that fluidly communicate with the cooling channels; and flow directing structure formed on the outboard surface of the tip shroud. The flow directing structure may be positioned relative to the outlet ports and configured for directing the flow of coolant discharged from the outlet ports. The rotor blade may be useful to reduce local tip shroud temperature as well as improved stage aerodynamic efficiency by reducing the coolant supply needed to maintain the component at desired temperature levels.

Abstract: A system and method for performing laser induced breakdown spectroscopy during laser ablation of a coating, such as a TBC coating, deposited on a surface of a component, particularly to enable obtained spectrometry signals of the ablated coating to be used to monitor and control the laser ablation removal process in real-time. The system includes a laser energy source and a scan head interconnected with the laser energy source to receive a laser beam therefrom and then direct the laser beam onto the surface of the coated component. Collection optics collect radiation emitted from a laser-induced plasma generated by the laser beam at the surface of the coated component. The system is further equipped to spectrally analyze the radiation and generate a feedback signal for control and optimization of one or more operational parameters of the laser energy source in real-time.
