Abstract
A wastewater filter assembly has a base, a filter module or casing, modular filter plates disposed in said filter module or casing atop the base, a header disposed on the filter module, tie rods each coupled at a lower end to the base, and tensioning elements removably connected to upper ends of the tie rods to fix the tie rods to the filter module and press the filter plates into relative rigid relationship. The tie rods are disposed in laterally open elongate channels extending along vertical edges of the filter module. The tie rods, upon a loosening or removal of the respective tensioning elements, can be shifted at least partially in a horizontal direction out of the laterally open elongate channels and laterally away from the filter module.
Claims16
An assembly for filtering water in wastewater and water treatment applications, comprising:
- a base;
- at least one filter module or casing supported on said base;
- a plurality of filter plates disposed in said at least one filter module or casing;
- a header disposed on top of said filter module;
- a plurality of tie or clamping rods each coupled at a lower end to said base;
- and
- a plurality of tensioning elements removably connected to upper ends of respective ones of said tie or clamping rods so that said tie or clamping rods press said at least one filter module or casing into rigid relationship with said base,
- wherein said tie or clamping rods are disposed along an outer side of said filter module or casing so that at least one of said tie or clamping rods can be moved at least partially laterally away from said at least one filter module or casing upon a loosening or removal of a respective one of said tensioning elements from said at least one of said tie or clamping rods.
A method for use in wastewater and water treatment applications, comprising:
- providing a filter assembly including a base, at least one filter module or casing, a plurality of filter plates disposed in a stacked configuration in said filter module or casing atop said base, a header disposed on top of said filter module or casing, a plurality of tie or clamping rods each coupled at a lower end to said base, and a plurality of tensioning elements;
- removably connecting said tensioning elements to upper ends of respective ones of said tie or clamping rods so that said tie or clamping rods press said at least one filter module or casing into rigid relationship with said base;
- disposing said filter assembly in a wastewater container of wastewater;
- subsequently removing at least one of said tensioning elements from the upper end of the respective one of said tie or clamping rods;
- after the removing of said at least one of said tensioning elements, moving the respective one of said tie or clamping rods laterally away from said filter module or casing;
- thereafter conducting a maintenance or repair operation on said filter module or casing or one or more of said filter plates;
- thereafter moving said respective one of said tie or clamping rods back towards said filter module, laterally relative thereto;
- and
- subsequently reattaching said at least one of said tensioning elements to the upper end of the respective one of said tie or clamping rods.
