Definitions

  • Filter panel for the treatment of liquids, especially for disc wastewater filter equipment
  • the subject of the invention relates to a filter panel for the treatment of liquids, especially disc wastewater filter equipment, which has a supporting frame surrounding the permeable surface, as well as at least one filter insert that fills in at least a part of the permeable surface fixed to the supporting frame, where at least a part of the filter insert is formed as a spatial shape consisting of shell elements protruding from the plane, the supporting frame has at least three sides connected to each other, and the supporting frame has one or more supporting ribs running through the permeable surface, where the supporting ribs have a rest surface and at least some of the shell elements of the filter insert are in contact with at least a part of the rest surfaces of the supporting ribs.
  • Publication document number WO 2012/158012 and patent specification registration number HU E009445 present modularly constructed wastewater treatment facilities that may be expanded in the case of an increase in the load, what is more, in a given case the effectiveness, performance of certain treatment steps may also be varied.
  • the disadvantage of the filter inserts used in disc filtration equipment is that the filter surfaces are prone to become clogged, which significantly reduces the efficiency of suspended solids separation, so reducing the speed of the process.
  • a further disadvantage is that the filter inserts used contain planar filter surface elements, which also presents an obstacle to filtration efficiency and filtration performance.
  • Our objective with the solution according to the invention was to overcome the deficiencies of the known filter panels and to elaborate a version which, with a given flow cross-section, provides the greatest possible filtration surface and in which the filter panel back-washing characteristics are more favourable than those of the known constructions, furthermore, in which, with the same volume flow, smaller or even fewer devices fitted with the filter panel according to the invention are required in order to achieve the desired effluent water limit value.
  • the basis of the idea behind the invention was formed by the recognition that if the filter surface is formed in a different way, i.e. not using the usual planar part-elements but from space-curved surface pieces, e.g.
  • the filter panel according to the invention for the treatment of liquids, especially for disc wastewater filtering equipment - which has a supporting frame surrounding the permeable surface, as well as at least one filter insert that fills in at least a part of the permeable surface fixed to the supporting frame, where at least a part of the filter insert is formed as a spatial shape consisting of shell elements protruding from the plane, the supporting frame has at least three sides connected to each other, and the supporting frame has one or more supporting ribs running through the permeable surface, where the supporting ribs have a rest surface and at least some of the shell elements of the filter insert are in contact with at least a part of the rest surfaces of the supporting ribs - is set up in such a way that at least some of the shell elements are formed by a set of curved space element pieces an-anged next to each other, and at least some of the neighbouring curved space element pieces are connected to each other with a curved linking member.
  • a further feature of the filter panel according to the invention may be that the curved space element pieces are cylinder pieces.
  • the supporting frame has a first carrying member and a second carrying member, and the filter insert is clamped between the first carrying member and the second carrying member. Also, the supporting frame has four sides.
  • both the first carrying member and the second carrying member are fitted with supporting ribs, on the rest surface of the supporting ribs of the first carrying member facing the second carrying member there is a negative pattern formed conforming to and following the cross-sectional line of the curved space element pieces and linking members of the filter insert, while on the rest surface of the supporting ribs of the second carrying member facing the first carrying member there is a positive pattern formed conforming to and following the cross-sectional line of the curved space element pieces and linking members of the filter insert.
  • the curved space element pieces and the curved linking members are formed from a single material.
  • the longitudinal axes of the curved space element pieces forming the shell elements are parallel to one another, and the longitudinal axes are at an angle to any side of the supporting frame that differs from the perpendicular.
  • the most important advantage of the filter panel according to the invention is that as a consequence of the novel shape of the filter body in the case of the same flow cross-section a significantly more effective filter surface can be created than in the case of the filter panels of traditional disc filter equipment, and so with a smaller device the same capacity of traditional solutions can be achieved, or in the same equipment volume a greater filtration capacity can be established.
  • a further advantage is that due to the curved filter surface profile pieces, which differ from traditional set-ups, significantly more effective back-washing can be achieved, due to which there is significantly less chance of the filter panel becoming clogged or of its effectiveness deteriorating.
  • a further advantage deriving from this is that the lifetime of the filter panel according to the invention is greater, and its maintenance demand is lower than that of the usual filter panels.
  • Another advantage due to the unusual form is that the curved space element pieces assist the "carrying off of the concentrate sticking to the filter surface, as they guide the concentrate and force it into the appropriate direction, towards the collection channel.
  • Another advantage related to the filter panel according to the invention is that equipment fitted with it is able to process the same volume of treatable liquid can be processed with less equipment than devices that use traditional filter panels. Therefore, by using the new filter panel the phase separation capacity of existing wastewater treatment plants can be increased with minimal transformation work without having to increase the area used.
  • An additional advantage deriving from this is the small investment cost and the reduction of the specific operation and maintenance costs as well.

It can be observed how the two neighbouring curved space element pieces 21a protrude from the plane "S", and how a curved linking member 21b is positioned between each two curved space element pieces 21a. Naturally it is practical if the curved space element pieces 21a and the curved linking members 21b forming the shell elements 21 forming the filter insert 20 are constructed from a single filter material.

  • the filter insert 20 When using the filter panel 1 the liquid passing onto the filter insert 20 of the filter panel 1 flows over the curved space element pieces 21a of the shell element 21 , and depending on the size of the opening of the filter insert 20 of the filter panel, the filter insert 20 retains the particles that are larger than the size of the opening.
  • the particles stuck on the input side of the filter panel 1 - in the case of a suitable curved linking member 21b size selected to comply with the size of the opening of the filter insert 20 - are unable to remain, get stuck between two neighbouring curved space element pieces 21a, therefore these sections of the filter insert 20 do not get clogged either.
  • the jet of liquid performing the washing of the filter insert 20 - also as a result of the control ability deriving from the shape of the curved space element pieces 21a forming the shell elements 21 of the filter insert 20 - passing along the appropriate "channel” is able to wash out the pores of the filter insert 20 of the filter panel 1 in a shorter time and with greater effectiveness.
  • the filter panel according to the invention may be applied to good effect in all places where a reliable filter device that is less prone to faults and clogging is required for the performance of high-capacity and effective phase separation.
