Definitions

  • This invention is concerned with improvements relating to water delivery apparatus, and provides, on the one hand, an apparatus for the delivery of a supply of water (e.g. to a fish pond) from which certain impurifications have been removed, and on the other hand a water delivery apparatus to an assembly for the growing of plants.
  • a supply of water e.g. to a fish pond
  • a water delivery apparatus to an assembly for the growing of plants.
  • a problem occurs in water delivery apparatus, in the separation of suspended solids from the water in a first stage purification operation, and in the subsequent delivery of the water to a second stage purification operation, in which materials dissolved in the water are treated.
  • a water delivery apparatus comprising a chamber to which in use water is delivered, and comprising, located in the chamber, a medium for the treatment of the water, in particular for the treatment of dissolved materials, wherein at least one side of the chamber comprises a porous member.
  • the porous member may permit gases to pass to and/or from the chamber, and further or alternatively the porous member may permit liquids to pass to and/or from the chamber.
  • the medium for the treatment of the water may be in any convenient form, but is conveniently afforded by a material having a high surface area, whereby bacteria or other micro-organisms may attach themselves to the surface, to treat materials within the water by a biological process.
  • the medium may be in the form of ribbons of plastics material, over which the water trickles, increasing the oxygen content of the water, and exposing the water to a large surface area of treatment medium.
  • the medium may be in the form of clay crocks, ceramic or plastics rings, stones or the like. Further alternatively, the medium may comprise barley straw, the decomposition products of which inhibit the growth of undesired "blanket weed” filamentous algae. 2
  • the water delivery apparatus may also comprise a second chamber, generally upstream of the first said chamber.
  • the second chamber is located generally within the first chamber, and conveniently is concentric therewith.
  • water may flow generally upwardly within the second chamber, and from an upper part of the second chamber generally downwardly into the first chamber.
  • solid content in the water moves generally downwardly within the second chamber, and water with a lower solid content flows generally upwardly within the second chamber.
  • a filter means generally upstream of the first chamber.
  • the second chamber may comprise a conical section to which the water is delivered, there being provided an inlet means for tangential flow of the water into the conical section.
  • the lower region of the second chamber preferably extends to a discharge outlet for the discharge of the solid material, conveniently in suspension at a relatively high concentration in the water.
  • the second chamber also comprises an upper section which is conveniently cylindrical, from which water passes to the first chamber.
  • the first chamber is preferably located outwardly of the second chamber, the space between an outer wall of the first chamber and an outer wall of the second chamber constituting the first chamber.
  • an outlet is provided, from which water may be conducted as is required.
  • the water delivery apparatus above described is particularly suitable for use in the purification of water from a fish pond, water being pumped into the second chamber and flowing from the first chamber back into the pond.
  • solid materials such as faecal matter
  • dissolved materials particularly nitrogenous compounds such as ammonia and the like, may be converted by the bacterial action into nitrites and nitrates within the first chamber.
  • the apparatus comprises one or more containers such as pockets within which a growing medium such as compost may be located, and within which flowers or plants may be grown, to provide a decorative appearance to the apparatus.
  • a growing medium such as compost
  • the water for the growing medium may be derived from the water flowing through the first chamber, which being high in nutrient content provides efficacious conditions for such flowers or plants.
  • water may permeate from the first chamber into the growing medium in the pockets through the porous member, through which roots for the flowers or plants may also pass to obtain water from the first chamber.
  • the medium for the treatment of water comprises barley straw, or plastic ribbon, such a medium may also provide a root supporting medium for the flowers or plants.
  • the first chamber is defined on its outer side by louvre type members, i.e. a plurality of inclined slats or similar formations extending generally downwardly and inwardly from the outer side.
  • louvre type members i.e. a plurality of inclined slats or similar formations extending generally downwardly and inwardly from the outer side.
  • Such an arrangement is particularly effective to bring water flowing downwardly within the first chamber into intimate contact with the containing members within which the growing medium is located, thus providing efficient watering of the growing medium.
  • the louvre design reduces direct contact of the water with the growing medium, which may cause water logging by capillary action, which can occur when the first chamber is defined on its outer side by a porous member alone, such as a mesh.
  • the containers are attached to or integral with the outer side of the first chamber, and conveniently are provided at generally spaced positions, such that portions of the outer side of the first chamber are in contact with air around the container, thus enabling atmospheric oxygen to be dissolved into the downwardly flowing water, and also to enable carbon dioxide dissolved in the water to be gassed off.
  • the louvre arrangement is particularly suitable for both these purposes, since the inwardly and downwardly depending slats prevents leakage of water to the outside of the container, whilst freely permitting the gas exchange described above.
  • Water containing solids may flow through filter means prior to entering said second chamber.
  • water containing solids may flow upwardly within the second chamber through filter means prior to flowing from said upper part of the second chamber.
  • the second chamber comprises a lower section to which water is delivered for flow in a generally upward direction.
  • the second chamber may comprise a lower section of relatively small height into which water is initially admitted and through which water flows generally upwardly and a section of relatively great height containing said filter means.
  • the filter means may comprise layers of different porosity, and preferably the porosity decreases towards upper layers of the filter means.
  • the second chamber may be generally cylindrical.
  • the water may enter the second chamber at the lower end thereof through an inlet port in a generally vertically upwardly direction.
  • the inlet port may be disposed generally centrally of the lower section.
  • the container is in cylindrical form, means being provided to cause water to flow downwardly through the container, preferably through a medium on which bacteria may grow, such as plastics ribbons, clay crocks, packing rings, stones, barley straw or the like, such bacteria conveniently being utilised to convert impurities in the water, such as dissolved nitrogenous compounds such as ammonia and ammonia compounds, which in turn, together with trace elements, promote growth of the plants in the pockets.
  • a medium on which bacteria may grow such as plastics ribbons, clay crocks, packing rings, stones, barley straw or the like, such bacteria conveniently being utilised to convert impurities in the water, such as dissolved nitrogenous compounds such as ammonia and ammonia compounds, which in turn, together with trace elements, promote growth of the plants in the pockets.
  • the container is defined by a peripheral wall, which at least in the vicinity of the pockets is perforate, to allow moisture to pass outwardly of the container for the growing of plants within the pockets, either directly, or by being drawn therethrough by roots passing into the container.
  • the perforate peripheral wall portions may be provided by porous members, but preferably are provided by louvre arrangements comprising a plurality of generally downwardly and inwardly inclined slats, as detailed above in relation to the first aspect of this invention.
  • the container is provided with a drainage outlet extending from a lowermost part thereof, and a water outlet extending from the container at a height above the drainage outlet.

Abstract

Ce dispositif d'approvisionnement en eau comprend une chambre (22) alimentée en eau qui, lors de son utilisation, comporte un milieu de traitement de l'eau, notamment de traitement de matières dissoutes, et dont un côté au moins présente un élément poreux, lequel permet à l'eau située dans la chambre de passer à travers la paroi de celle-ci, et aux gaz dissous de passer dans l'eau et de provenir de celle-ci. On peut ajouter en outre des contenants (26) sur le côté extérieur (20) de la chambre, dans lesquels on peut placer un milieu de culture ainsi que des végétaux. Les racines des végétaux peuvent passer à travers l'élément poreux de manière que des composés dissous, tels que des nitrates et des composés ammoniacaux, puissent apporter des éléments nutritifs aux végétaux, de tels composés étant alors simultanément enlevés de l'eau, purifiant ainsi celle-ci.
