Ceramic media
Koch Knight LLC introduces Flexeramic® structured media for RTO applications. Designed for long-lasting performance, the corrosion-proof media elements are composed of corrugated sheets of ceramic vertically aligned in the RTO media bed, eliminating any horizontal surfaces that may create resistance to vapor flow. After replacing existing random packed RTO beds with this media, users notice a pressure drop decrease of at least 20% and improved efficiency, resulting in significantly lower operation energy costs.

FRP corrugated baffle
MFG Water Treatment Products Company recently developed the next generation Corrugated-Density Current Baffle (C-DCB). The patent-pending advanced density baffle design features a unique corrugated shape that significantly reduces deflection of deposits from coming back up into the center of the clarifier. Comprised of FRP material, it’s also easier to install than previous designs due to the part being lighter in weight and requiring fewer fasteners then the previous designs. Stronger than standard designs despite no structural steel, the baffle is mounted on the side of the clarifier wall, below the effluent launder and scum baffle.
