Definitions

  • the present invention relates to a portable filtration device and, in particular, a. filtration device for removing solid matter from water.
  • a leakage of water or flooding occurs which results in ' a large volume of water containing solid, semi-solid or particulate material. This can often occur when work is being carried out involving underground cables or pipes or to repair broken water pipes.
  • flooding occurs, a large volume of water which contains such solid material may need to be removed from the location before further or remedial work can be carried out.
  • the dirty water may simply be pumped to another location, such as a holding tank,, or pumped into the mains drainage system.
  • the latter option has the disadvantage of introducing a large amount of solid and semi-solid material into the mains drainage system which can block pipes and cause further damage and flooding, and is therefore forbidden in some countries.
  • devices for cleaning water contaminated by solid and semi-solid particulate material are known, these are generally fixed systems which are constructed at ' a particular site to deal with a specific long term problem; as disclosed in US4689145A, JP2000070617A and FR2833855A.
  • the devices disclosed in these documents cannot be transported or installed quickly in order to deal with unexpected or temporary leakage of water or flooding.
  • the present invention seeks to provide a filtration device to alleviate these problems.
  • a portable device for filtering water comprising an inlet, a filtration zone and an outlet, whereby water to be filtered enters the filtration zone through the inlet, passes through the filtration zone and passes out through the outlet, the filtration zone comprising a plurality of filters of decreasing mesh size.
  • portable it is meant that devices of the present invention may be transported from site to site, and preferably without the need to use specialist lifting equipment.
  • devices of the present invention may be further adapted to make them easier to move into position, for example, by being fitted with handles to assist in their lifting and/or being fitted with wheels, which may be attached either to the base of the device or to a cradle adapted to receive the device of the invention.
  • devices of the present invention are generally rectangular, having a length in the direction of the flow of water preferably of from 1 to 5m, more preferably 1 to 2m, for example 1.2m.
  • Devices of the present invention also have a preferred width of from 400mm to lm, more preferably 500mm to 700mm, for example 640mm, and a preferred depth of from 400mm to lm, more preferably 500mm to 750mm, for example 640mm.
  • Devices of the present invention will preferably have an overall volume of from 100 to 5000 litres, more preferably from 200 to 2000 litres, and most preferably from 300 to 750 litres .
  • Devices of the present invention may be made of any material having sufficient rigidity to withstand the weight of water that will be contained when the device is operating at full capacity, for example, stainless steel, aluminium or suitably reinforced fibrous materials.
  • one or more of the filter plates is removable.
  • the device further comprises one or more baffle plates.
  • one or more of the baffle plates is ' removable .
  • the device comprises at least two filters, more preferably at least 3 filters.
  • at least one of the filters is removable, and more preferably all of the filters are removable. This permits blocked filters to be cleaned and damaged filters to be easily replaced.
  • the pore size of the filters used in devices of the present invention may be selected to take into account the type and variety of materials contaminating the water to be filtered. For example, when the contaminating material is relatively large at least one filter having a large pore size will be preferred, whereas when the contaminating material is generally small and semi-solid, or particulate, at least one filter having a small pore size will be preferred. Various combinations of filter sizes may also be used when there is a mixture of contaminants of various sizes present.
  • the first filter will have apertures of from 3 to 7.5mm in diameter, preferably 5.5mm
  • the second filter will have a mesh size of from 100 to 500 microns
  • the third filter will have a mesh size of from 10 to 150 microns.
  • the filters comprise cross-weave/woven stainless steel mesh.
  • the device is for filtration of muddy water.
  • the inlet of the devices of the present invention may comprise a single entry port, to which may be connected a pipe leading from a pump draining the water that is to be filtered or, alternatively, may comprise two or more such entry ports.
  • the outlet of devices of the present invention may comprise a single conduit through which water may be passed out of the device, or may comprise two or more such conduits, preferably three.
  • Devices of the present invention preferably comprise acces.s points in the top of the device, and more preferably are fitted with a lid to provide access to the interior of the entire device, so that, for example, the filters and any baffle plates that may be present may be inspected, cleaned and/or replaced.
  • a lid may be fully removable, or may be hinged. It is preferred that, if the device of the present invention comprises one or more access hatches or a lid, means are also provided to ensure that the access hatches or lid, can be secured in the closed position, for example, catches or locking mechanisms.
  • devices of the present invention are fitted with an overflow port, preferably at the end of the device into which water first flows, to ensure that water that has not passed through the device is returned in the direction from which the contaminated water reaches the device, rather than in the direction in which treated water is passed.
  • the present invention also provides a method of removing solid, semi-solid or particulate materials from water containing such materials, comprising pumping the water to be treated to the inlet of a device of the present invention, passing the water through the filtration zone and out of the outlet thereof.
  • Water filtered through devices of the present invention by the method of the present invention may be further treated after passing out of the outlet of the device of the present invention, for example, by passing through further filters (eg, sponge or depth filters) , and/or by being pumped into a dry-well which might be dug at a particular site if a particularly heavy leakage or flooding had occurred.

Abstract

La présente invention concerne un dispositif portable conçu pour permettre le filtrage de l'eau, lequel dispositif comprend un orifice d'amenée, une zone de filtration et un orifice de sortie. Selon le mode de réalisation décrit dans cette invention, l'eau qui doit être filtrée pénètre dans la zone de filtration par l'intermédiaire de l'orifice d'amenée, puis elle traverse la zone de filtration pour ressortir par l'orifice de sortie. La zone de filtration comprend plusieurs filtres présentant une dimension des mailles décroissante. De préférence, les filtres et/ou les déflecteurs peuvent être retirés du dispositif. Dans un mode de réalisation privilégié, les filtres sont réalisés à partir d'un maillage en acier inoxydable tissé/à chaînes croisées et le dispositif est adapté à la filtration d'eau boueuse.
