Definitions

  • This invention relates to a waste water treatment plant, more particularly, though not exclusively, a sewage waste water treatment plant, for obtaining water which is useful, inter alia, for irrigation in agriculture and horticulture, landscaping and so on.
  • the invention proposed herein is compact in construction and efficient in operation.
  • the waste water treatment plant comprises a sump for collection of the waste water; a flocculation chamber for flocculating the waste water from the sump received in the flocculation chamber; a water clarifier for clarifying the water received from the flocculation chamber, said clarifier comprising a chamber accommodating a plurality of spaced plates, placed one against the other, each plate having an aperture at the center, the plates fully spanning the chamber; a grill fixed, at an inclination, to each plate, over the aperture, for enabling the water, required to be clarified, to pass there through and cause the solids in the water to be separated, while the space between the plates creates a turbulence in the water as it passes from one grill to another, the turbulence simultaneously flocculating the water in the said space; an inlet for the entry of the water to be clarified into the chamber, and an outlet for the exit of the clarified water from the chamber; a bioreactor for bioreacting with the water received from the clarifier, said biorea

  • Fig. 2 illustrates the water clarifier
  • Fig. 3 illustrates the bioreactor
  • Fig. 4 illustrates the floating ball biofilter (separate view of a ball)
  • Fig. 6 illustrating layers of such balls floating in the water to be treated.
  • the sump Y is for collection of the waste water to be treated. From the sump Y the waste water is pumped by a pump K into a known flocculation chamber F provided with a 0.5 HP stirrer where the waste water is flocculated with lime, water and a coagulating agent. From the chamber F the flocculated water is pumped into a water clarifier U.
  • C is a chamber (shown in broken outline) accommodating a plurality of spaced plates P, placed one against the other.
  • Each plate has an aperture A at the center, the plates fully spanning the chamber.
  • a grill G is fixed, at an inclination, to each plate O, over the aperture A, for enabling the water, required to be clarified, to pass through the grills and cause the solids in the water to be separated and collect at the bottom of the chamber.
  • One of the ways of fixing a grill G, at an inclination, to each plate P is by fixing one end G1 of the grill to the corresponding end of the plate P1 and extending the other end of the grill G2 slightly beyond the corresponding endP2 of the plate P, to overhang the plate P at that end P2.
  • the chamber C has an inlet I for the entry into the chamber of the water to be clarified; and an outlet O for the exit out of the chamber of clarified water.
  • V is a bioreactor for bioreacting with the water received from the clarifier U.
  • At least one chamber O accommodates a plurality of spaced wheels W, the wheels being rotatably mounted in juxtaposition, on a central shaft, the wheels spanning the chamber and being partially submerged in the water to be treated.
  • the wheels W have deposited on them bacteria, which are selected to react with, and degrade.
  • the impurities in the water as the wheels rotate in the water in the chamber.
  • the precise nature of the bacteria will be determined by the nature of the impurities in the water to be treated.
  • the chamber M will have a curved base D to cooperate with the curvature of the wheels W.
  • the wheels W are provided with a web like surface Z for receiving and carrying bacteria.
  • a chamber I accommodate two layers L L of balls B floating in the water to be treated, each ball having slots R with bacteria deposited in them.
  • the bacteria is selected to react with, and degrade, the impurities in the water to be treated passing (in the direction of the arrows X through such slots.
  • the balls B in each layer have predetermined densities less than the density of the water, enabling them to float at predetermined levels in the water.
  • the water to be treated passing in the upward direction thus gets thoroughly clarified/filtered during its upward journey through the slots in the balls by interaction with the bacteria in the slots, which degrade the impurities in the water, and also by passing through the staggered slots in the balls.
  • the balls are preferably made of plastic.
  • the impurities degraded and physically filtered collect at the bottom of the tank, while the bio-filtered water rises to the top and is taken away for further processing, if necessary.
  • the sludge and other impurities are taken to a vermicomposting unit H for disposal.
  • the water from the floating ball biofilter is taken to a disinfection unit provided with a 0.5 HP stirrer for agitation.
  • the unit is provided with known disinfectants.
  • the sand filter will be operated under gravity pressure and constant flow.
  • the water from the above mentioned filter is then sent to a second sump T for collection of the treated water. Before sending the water to the sump T it is recycled if necessary to the said filter for a second round of filtration at this point.
  • the sludge from the said filter is taken to the vermicomposting unit H.
