Abstract: A method and apparatus for diffusing a liquid condensate return stream in an industrial steam condenser to reduce erosion and corrosion on the condenser structure. One or more diffuser screens are located intermediate a sparger nozzle and a condenser structure to diffuse the condensate screen prior to impact on the condenser structure.

Abstract: A method and apparatus for automatically propelling a charge of backwash fluid by a compressed gas such as steam to backwash a filter in a filter pair. The method and apparatus provides for backwashing a filter with at least three backwash phases, a first mainly comprising a charge of backwash fluid passing through the filter with significant speed, a second relating to use of flashing steam for secondary cleaning and scrubbing of the filter elements, and a third relating to use of low pressure steam for autoclaving and sterilizing the filter.
