Definitions

  • the present invention relates to control software required for the operation of a balance tank reactor as described by Olaopa Process in European Patent No. 1196354 and US Patent No.: 6562237.
  • Olaopa Process describes a biological reactor for the reduction/elimination of nitrogen and/or phosphates incorporating balancing of reactor' s constituents in such a way as to maintain a constant hydraulic retention time (HRT) within the tank under variable flow regime.
  • HRT hydraulic retention time
  • the outlet from the reactor is located below top water level and the outflow can be controlled with a pump or control valve.
  • anoxic/anaerobic reactors are defined on the basis of the influent displacing similar volumes on the outlet.
  • Olaopa Process (Pat.No.rEP 1 196354 & US 6562237) referred to in this invention is the only anoxic/anaerobic reactor allowing for variable flow rates on the inlet and controlled flow on the outlet of the reactor.
  • control panel incorporating computerised software allowing variation of hydraulic retention time within a biological reactor primarily used for the dissimilatory reduction of nitrates to nitrogen.
  • the control panel may also have incorporated into it computerised software allowing variation of mixing ratio of the influents into the biological reactor typically crude wastewater and nitrified re-circulating mixed liquor.
  • an operator will define a hydraulic retention time and mix-ratio on the control panel.
  • the computer programme Upon pressing 'START' on the panel the computer programme will control the volume of nitrified effluent to be mixed with the crude wastewater to the treatment plant and the hydraulic retention time within the biological reactor.
  • a hydraulic level sensor will read the top water level in the reactor, calculate the volume of the liquid in the reactor and use the reactor volume and selected hydraulic retention time to set a pumping flow rate out of the reactor. If the level in the tank rises there will then be a corresponding increase in pumping rate and vice versa. This will be sufficient if the software is for the control of hydraulic retention time only.
  • the mixing ratio of the re-circulating influent and crude wastewater influent is selected and the desirable hydraulic retention time (HRT) is also selected.
  • the incoming flowrate and desirable HRT is used to calculate appropriate hydraulic level in the reactor. Where the desirable hydraulic level does not match existing hydraulic level in the reactor, the discharge pumping rate can be increased or decreased.
  • This programme can be used for the control of a flow mix into the reactor (re-circulating nitrified influent and crude wastewater) and maintaining a specified hydraulic retention time under variable flow regimes.
  • the volume of liquid in the reactor and the selected hydraulic retention time will be used to calculate the percentage opening of a control valve located on the discharge pipework from the reactor.
  • the control panel can contain either or both of the controls described i.e. hydraulic retention time only or hydraulic retention time and mix-ratio.
  • control panel according to the present invention remain applicable to the simultaneous control of mix ratios into the anoxic/anaerobic compartment(s) and any control of hydraulic retention time within the tanks.
  • control panel can be applied to the aerobic compartment of any biological reactor.
