Bioctor S Description

Nijhuis Water Technology, designs and supplies a complete range of aerobic biological treatment systems, where bacteria will remove dissolved materials from your waste water. The Sequence Batch Reactor (SBR) is one of the systems Nijhuis Water Technology designs. Depending on your waste water capacity and consistency an SBR system can be designed.

The mainly soluble matter is removed by biological treatment. Biomass converts organic matter to water, carbon dioxide an new biomass.

A Nijhuis Water Technology SBR design can consist of the following steps:

  • Selector
  • SBR tank with the following operations:
  • Aeration
  • Denitirfication (if applicable)
  • Settling
  • Discharge

This aerobic biological treatment process requires input of air. The most common used ways of aeration is either fine bubble bottom aeration or surface aeration. The amount aeration is controlled by an oxygen measurement installed in the MBR tank and is programmed in such a way that the power consumption is minimal.

Bioctor S - Customer Benefits

  • All operations take place in one tank
  • Discharge of batch volume in 2 - 3 hours per day
  • Very suitable for nitrification, denitrification and phosphorous removal
  • Easy in operation
  • Can handle flow and pollution variations
  • Single batch, double batch and multiple batch variations

Bioctor S - Technical Data

1) Selector
Selector tank in which bacteria are in contact with BOD (raw influent) in order to give flock building bacteria an advantage over filamentous bacteria.

2) Nutrient and Phosphor precipitant dosing (if required)
When there is a lack of nutrients in the water these have to be added to create a healthy biomass For phosphorus removal dosing of a precipitant will be required

3) SBR tank

  • Aeration of biomass/water mixture
  • Denitrification in non aeration periods
  • Settling of the biomass
  • Discharge of treated water

4) Water discharge
The treated water will be discharged from the SBR tank by the floating discharge

5) Sludge return and excess sludge

  • Sludge return flow will be pumped to the selector
  • Excess sludge will be discharged, further dewatering is a possibility
