SUPERFLOT™ - BIOGAS for the best solids-liquid separation in anaerobic wastewater treatment systems

The GWE SUPERFLOT™ - BIOGAS system is used for the highly-efficient removal of anaerobic biomass from the effluent of an anaerobic treatment system. Within the unit, the biomass from the anaerobic reactor is separated from the treated effluent via a Dissolved Biogas Flotation (DBF) process.

As a part of our FLOTAMET™ system, SUPERFLOT™ - BIOGAS achieves outstanding treatment results in many industries where the high biological content and elevated suspended matter must be completely removed.

How can the SUPERFLOT™ - BIOGAS system benefit your business?

  • Delivers consistent, reliable operation and superior wastewater treatment efficiencies;
  • Can reduce required process volume and footprint of anaerobic treatment systems;
  • Incorporates transparent roof panels for easy monitoring;
  • Completely sealed construction; no biogas release to the atmosphere and odor-free operation;
  • The high solids concentration of the separated sludge reduces disposal costs of any excess anaerobic sludge;
  • Can be employed in new systems and to upgrade existing anaerobic systems to improve performance.

Industries and applications: together with the anaerobic waste and wastewater treatment where the biogas can be utilized for solids-liquid separation, for high solids wastewater treatment in industries such as diary and ice cream production, chocolate, confectionaries, distilleries, palm oil production, pet food manufacturing and many more.

How does the SUPERFLOT™ - BIOGAS work?

SUPERFLOT-AIR scheme

The anaerobic biomass solids are floated to the surface of the SUPERFLOT™ - BIOGAS by a curtain of fine biogas bubbles, similar to the function of the air bubbles in the SUPERFLOT™ - AIR. The fine biogas bubbles are created by dissolving biogas under pressure within a stream of recycled effluent from the unit. After injection of this stream into the lower part of the flotation chamber, the subsequent pressure release results in the formation of fine biogas bubbles, which float to the water surface, carrying the anaerobic biomass solids with them.

Consequently, a floating layer of solids is formed on the surface of the SUPERFLOT™ - BIOGAS which can be easily removed. In order to remove any settled sediment from the flotation unit, the system can be equipped by means of a bottom auger for automated sludge removal.

The separated sludge is returned to the anaerobic system, increasing the biomass concentration and overall sludge retention time within the system. Consequently, the required process volume of the anaerobic treatment system can be significantly reduced, which provides significant economic and system footprint advantages.

In order to maintain a completely anaerobic atmosphere, prevent the loss of biogas to the atmosphere, avoid any issues with odor, and to avoid the introduction of air into the anaerobic treatment process, the system is a completely sealed, gas-tight unit. The largely pre-fabricated system is delivered primarily assembled and can be utilized in both new systems and added to existing reactors, in order to improve treatment performance.
