Aecobed MBBR

Aecobed MBBR Description

Nijhuis Water Technology, designs and supplies a complete range of aerobic bilogical tratment systems, where bacteria will remove dissolved materials from your waste water. The Aecobed concept makes use of MBBR technology, where biomass is growing and fixed on carriers. Depending on your waste water capacity, composition and effluent requirements the optimum Aecobed concept can be designed.

The mainly dissolved organic matter is removed by biological treatment. Biomass growing on the MBBR carriers convers organic matter to water, carbon dioxide and new biomass.

A Nijhuis Water Technology continuous biological treatment design can consist of the following steps:

  • (staged) Aecobed MBBR tank with carriers
  • Integrated carrier filter(s)
  • Denitification starge (if applicable)
  • Optional flotation system for polishing and excess sludge removal

This aerobic biological treatment process requires input of air. The most common type of aeration is bottom aeration, which also mixes the water with the carriers.

The amount of aeration is controlled by an oxygen measurement installed in the aeration tank and is programmed in such a way that the power consumption is optimal.

Aecobed MBBR - Technical Data

1) 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

2) Aecobed aeration tank
Aeration tank where biomass is growing and fixed on carriers

3) Carrier filter system
Internal carrier and water separator

4) Flocculation - flotation system (optional)
Waste water polishing and excess sludge removal
