  • Patent number: 5951855
    Abstract: A filter and hydraulic mixing assembly for a water treatment system. The assembly includes two circulation tubes disposed alongside a center tube. During a backwash cycle fluid is conveyed through the center tube to a housing member where it is discharged immediately below the open bottom ends of the two circulation tubes thereby conveying media from the surrounding tank upwards through the circulation tubes. A cap member is fitted over the upper ends of the circulation tubes within the tank and direct the media being discharged from the circulation tubes into a downward spiraling helical flow pattern which provides enhanced agitation and lifting of the media bed. Discrete filter segments are selectively attachable to the housing member and interchanging the discrete filter segments permits the total filter slot area of the assembly to be adjusted and also permits the filter slot size to be altered. The filter segments are color coded, with each separate filter size having a different corresponding color.

  • Patent number: 5890750
    Abstract: The present invention involves a pressurized water treatment system and method having a unitary liner and flange and a plurality of interchangeable heads. The system utilizes non-threaded connections where periodic detachment is desirable to eliminate the cross-threading problems posed by plastic threads. The coupling devices include an improved clamp assembly to removably secure the water treatment heads to the liner flange or other system components and an improved spring clip to removably attach inlet and outlet lines to water treatment heads and fittings. By including L-shaped tabs, the spring clip reduces the chance of inadvertent dislodgement. The use of common connectors allows any of the interchangeable heads to be used with the liner and other fittings. Adapters can also be used to allow non-system components to be integrated into the system. A fill port adaptor can also be disposed between the liner and water treatment head to provide access to the tank interior without the removal of the head.
