Treatment Systems

With iQ.MBBR™ we introduce the next generation of Moving Bed Biofilm Reactor technology which combines robust, efficient design with smart iQ.CONTROLS™ - intelligence + quality.

The strength of MBBR

1

Utilizes the 

fluidized floating-bed principle

  • Ensures optimum utilization of the existing and introduced oxygen.

  • Significantly reduces the energy consumption for aeration.

  • Promotes a diverse community of microorganisms in the biofilm.

2

Functions on the
principle of a gravity flow

  • Eliminates pumps between the individual treatment stages.
     

  • Low pressure loss, saves energy.
     

  • Enhances the year-round operational stability and long-term reliability.

3

Utilizes a

pure biofilm

  • Operates without returning sludge to the biological stage.
     

  • Adapts flexibly to the properties of the wastewater.
     

  • Handles hydraulic and organic shock loads with ease.

Our special biofilm carriers

for optimal growth conditions

The specially developed carrier material is the most important element of our process. Optimum growth conditions on and in this material promote the development of a special biofilm matrix. The patented design of the carrier media also ensures self-cleaning capabilities: There is no clogging of the inner surfaces and it is thus not necessary to clean or replace the media.

​​

The high performance of our MBBR is based on the particular properties of the biofilm which is formed. It facilitates complex decomposition processes and achieves first-class treatment results. Even at a wastewater temperature of 4° C, as is the case on a cold winter day, the process functions with reliability.

Nutrient Reduction

If higher effluent standards are enforced, additional wastewater treatment is becoming increasingly important. This refers above all to demands for denitrification and phosphorus removal, as well as disinfection of the wastewater.

The unique layer structure of the MBBR biofilm and advanced operation , the system achieves already a high simultaneous denitrification also even at low wastewater temperatures.

Additionally, our MBBR offers a range of flexible treatment modules and process concepts for nutrient reduction. These modules can be used for new installations as well as for retrofits and/or upgrades.

Laminar Boundary Layer

The surface og the biofilm.

Aerobic Layer

Responsible for breaking down carbon compounds and for converting ammonium to nitrate.

Anoxic Layer

In the absence of dissolved oxygen, the bound oxygen of the nitrate is used for carbon conversion (denitrification).

Anaerobic Layer

In the absence of dissolved oxygen and nitrate, anaerobic decomposition of cells can occur

The iQ.MBBR Process

1. The sludge storage

is designed to provide combined concentration of primary and secondary sludge. For small plants, the Sludge Storage is generally integrated inline with the process; however, can be designed offline for larger plants. The Primary Clarifier is designed to remove any settleable solids from the sludge supernatant. 

2,3. The aerobic bioreactors

are designed as a low-rate MBBR process with intermittent aeration via blower(s) and fine bubble diffusers allowing flexible operational settings with minimal energy consumption, either manually set or automated using dissolved oxygen (DO) control.

4. The Secondary Clarifier

Utilizes the 

fluidized floating-bed principle

5. As effluent discharge

standards become more stringent, advanced wastewater treatment is becoming increasingly important, most commonly with respect to nitrogen and phosphorous removal, or disinfection of the effluent. The iQ.MBBR™ can be designed with a variety of modular treatment process which can be added to new plants or retrofit within existing installations. 

N1 [Nitrogen: 30% - 80% removal] - Pre-anoxic denitrification via recirculation of nitrified secondary process with or without carbon supplementation 
N2 [Nitrogen: 80% - 90% removal] - Pre-anoxic denitrification via recirculation of nitrified secondary process with orwithout carbon supplementation + side-stream anoxic treatment of recirculated effluent

N3 [Nitrogen: 90% - 95% + removal] - Pre-anoxic denitrification via recirculation of nitrified secondary process with or without carbon supplementation + tertiary (post-) anoxic treatment

P1 [Phosphorus: 􀀎 0.5 mg/L TP] - coagulant enhanced secondary precipitation 
P2 [Phosphorus: 0.3 - 0.5 mg/L TP] - coagulant enhanced secondary precipitation with floe reactor 
P3 [Phosphorus: 0.1 - 0.3 mg/L TP] - coagulant enhanced secondary precipitation + tertiary filtration 

C1 [Carbon Oxidation + Nitrification: 5.10 mg/L CBOD5, 5. 10 mg/L TSS, 5. 2 mg/L TAN] - Standard Cl)

C2 [Enhanced Carbon Oxidation + Nitrification: 5. 5 mg/L CBOD5, 5. 5 mg/L TSS, 5. 2 mg/L TAN] - Standard+ Tertiary Filtration

HS [High Strength for influent > 500 mg/L 80D5] - Standard+ lntermediate Clarifier

D1 [Disinfection: 5. 100 CFU /100 ml E. coli] - standard ultraviolet (UV) disinfection of secondary or tertiary effluent (higher reduction available)

Your iQ.MBBR™ Advantages at a Glance

The iQ.MBBR™ system is a robust, compact, cost-effective wastewater treatment process that provides optimal performance year-round. The system allows for significant operational flexibility where influent strengths and flows may vary from anticipated design. The main advantages are:

  • Quality: design, installation, service and operation

  • Intelligent controls with fully functional Remote Management

  • Advanced nutrient reduction and disinfection options

  • Adaptable biomass that continually regenerates and specializes to the process, is retained during hydraulic overload or organic under-load, and is resilient to seasonal and toxic shock loads

  • Simultaneous carbon oxidation, nitrification and denitrification - even at low temperatures

  • Combined storage of primary and secondary sludge enhances digestion and denitrification

  • Self-cleaning carrier media which never needs to be replaced - 20 year guarantee

  • Up to 80% energy savings with automated DO control: < operational cost + < carbon footprint

  •  Typically 50% lower sludge production than conventional activate sludge process

  • Aerobic bioreactor size typically <50% of conventional activate sludge process

  • Flexibility to adjust operational settings or add media to adjust to loading changes.

Up to 80% savings in energy cost when used with Dissolved Oxygen Control compared to conventional MBBR systems

DO Control vs. Standard Areation

Controls and Remote Management:

With the iQ.CONTROLS™ powered by 
the click+clean® platform BNA provides 
a unique control unit for the power and automatic control of the wastewater treatment system.

 

Each control panel comes standard with GPRS remote monitoring and data logging. This allows for instant notification of alarms with the capability for the operator to change settings remotely. Each output also monitors current (amperage) instead of relying on floats or sensors alone for mechanical failures. Current sensors can allow for issues to be detected before major problems occur. The control panel also has analog inputs for additional optional sensors (i.e., level. flow, pH, turbidity, dissolved oxygen, etc.). A battery backup is provided for each panel to ensure that notifications are still sent during power outages.
