  • Patent number: 10549007
    Abstract: A fluid filtration system is shown. The fluid filtration system utilizes a one-piece or multiple piece containers having a plurality of radiation-transmissible media adapted to receive light, such as ultraviolet light, white light or other wavelength light. The radiation-transmissible media are situated in the container and at least one or a plurality of radiation sources, such as ultraviolet lamps, are situated in an array in proximity to the radiation-transmissible media. The radiation-transmissible media interrupts the flow and velocity of the fluid stream passing through the container to extend the duration of radiation for any contaminants and also provide enlarged surface areas for the contaminants to be received and ultimately exposed to the radiation. In one example, the radiation-transmissible media may be tubular or spherical sections that are hollow or solid and made of quartz.

  • Patent number: 10486089
    Abstract: The present invention relates to a method of filtering a feed and waste water treatment system using the filtration method. The method utilizes a filtration cake for the filtration, which filtration cake is formed by elements contained in a liquid having a different composition than the feed to the filtered. The invention relates in particular to a method for filtering a liquid containing solid particles of different sizes which utilizes a filtration cake formed at least partly and preferably only from particles contained in said liquid containing solid particles of different sizes. The particles of the filtration cake are deposited on a filtration cake support and the method involves separation of the liquid containing solid particles of different sizes into two fractions: one fraction containing solid particles above a certain size and one containing smaller particles, and filtering the fraction containing smaller particles through the filtration cake.

  • Patent number: 10465941
    Abstract: The invention pertains to a filter retaining assembly which is rigid and self-supportive without requiring any additional structural reinforcement. The design maximizes the filter surface to be used for air filtration and increases the filtration efficiency. The invention is also designed to minimize the filter assembly size to fit into the valuable space when the air handling unit physical dimension is constrained. The invention uses integral construction methods to save assembly time and labor by eliminating the need of using alignment holes and fastening each individual frame to construct a conventional filter retaining assembly. The proposed method maintains flexibility of scaling to any filter size and quantity.
