  • the treated water obtained from the system according to the invention can optionally be disinfected before being used.
  • the system has been designed so that wastewater will never be visible as it will always be below the growth mediums surface or contained physically within the system structure. This is an important feature in terms of public health.

  • Biological filtration will occur on the surface of the porous filter mediums and plant roots, the porous filter medium includes that within the chamber and vertical trickle filters.
  • Biological pollutant and nutrient removal will occur via microorganisms and plant bioprocesses. Pollutants and nutrients may also be absorbed via physiochemical reactions between the pollutants and the physical surface of the porous filtration medium.
  • Nitrification involves the oxidization of nitrogen species by nitrifying bacteria in one or more aerobic zones, including the vertical trickle filter. Then the nitrates are converted to dinitrogen gas by denitrifying bacteria in the anaerobic zone within the chambers A, B or C. The aeration stages of the system will aid in nitrification of the wastewater. A volume of Nitrogen will also be taken up into the plants and retained in their biomass.

  • the wastewater will enter the system via a controlled pumping regime.
  • the water volume entering the system will vary depending on the application.
  • the system can be extended linearly to increase the capacity, in this case the form and function of the system will remain as described here. It is expected that the system can deal with the daily flux by having a storage capacity in the sump that precedes the system, of 300 litres and having a sewerage over flow point in this sump.
  • the sump in some embodiments can have a preliminary filter screen.
  • the loading rate for chambers A, B and C and the vertical trickle filter is important. Too high a loading rate will lead to flooding. Further, whilst in some circumstances the wastewater alone can provide suitable nutrients for the plants 1 to thrive, a small amount of organic material is usually added to improve growing conditions. However, this can decrease the hydraulic conductivity of the porous medium 2 thereby requiring a reduced loading rate. It is also desirable to have a finer porous medium to increase the surface area for treatment. However, such a medium is prone to clogging and therefore lower loading rate will decrease maintenance requirements. A reduced loading rate is therefore desirable. In general the loading rate for the chambers and the vertical trickle filter is sought to be optimal and will depend upon the material and conditions maintained in the chambers.
  • the hydraulic load on the system will depend on the application and treatment requirements. For example, if the system requires water to be treated to a higher degree for reuse in toilet flushing or washing machines, a lower hydraulic load rate is to apply. Conversely if the waste water is to be used only for sub- surface irrigation, a higher hydraulic load rate may be applied.
  • the scale of the system can be adjusted depending on the volume and degree of water treatment required.
  • the system according to the invention in one preferred embodiment (Fig. 2) has a vertical trickle zone of approximately at least 80 cm, preferably at least 100 cms and most preferably at least 150 cms.
  • the lengths for fig 1 and 3 are approximately 1 linear metre per bedroom, i.e. 1 metre for 2 persons greywater.
  • the length can be longer if the boxes were skinnier or shorter if they were wider and is also dependent on depth, i.e. depending upon the application the length can be customised.
  • This design allows for better distribution and provides a better performance than the study mentioned above. As such it is expected that the proposed system can achieve an overall similar Biological Oxygen Demand (BOD) reduction. Performance can be further improved by using a finer medium.
  • BOD Biological Oxygen Demand
  • the water is required to be retained in the simulated wetland environment provided by chambers A, B and C.
  • the retention time and subsequent treatment of water is further dictated by the storage volume within the medium's pore spaces and the hydraulic loading rates within the chambers.
  • This treatment should provide a further reduction in BOD of around 55 % from the effluent that entered chambers A, B and C.
  • the water leaving the chamber B should have a BOD of less than 14.9mg/L. This is within the limit for recycled greywater standards required to reuse greywater for toilet flushing, washing machines and above ground irrigation.
  • the level of Nitrogen removal is harder to estimate.
  • the water entering the chamber B will be highly aerated and therefore only small anoxic zones will be present to aid in de-Nitrification.
  • a medium structure will be used to aid in the development of such zones.
  • the effectiveness of the medium to remove phosphorous cannot be determined empirically.
  • the vertical trickle zones 19 are expected to further assist in the reduction in BOD and SS.
  • Table 1 shows the expected reductions in pollutants between each stage. These are conservative figures, they do not take into account the effect of the vertical trickle zones and assume conservative levels for the individual chambers, i.e. A, B and C, level of performance. For example it is expected that Stage 3 will not provide the same level of treatment as stage 1, due to less defined drying periods therefore the level of treatment by this stage has been assumed to be much lower.
  • thermo tolerant coliform expected at each stage has not been calculated empirically. These bacteria do not survive long outside the warm conditions within the body, and will therefore be deplete with time and be destroyed physically within the system according to the invention.
  • the testing regime covered 3 years over 11 test runs. Testing was completed by SGS Australia. These results relate to two systems according to the invention (GreenwallTM), designed to service 3 and 4 bedroom homes respectively. A typical width would be about 1 meter per bedroom.
