HyVAB – Hybrid Vertical Anaerobic Biofilm

Our most advanced ultra-high rate technology

The HyVAB has been developed by Biowater Technology, with support from The Norwegian Research Council and Innovation Norway, combining Anaerobic Digestion with our patented CFIC® biofilm technology.

Space Saver, Energy Generator

As an ultra-high rate technology, HyVAB offers a footprint significantly smaller than conventional treatment. This is due to an innovative tower arrangement which minimizes sludge production offering considerable saving potential to the end user. HyVAB also offers superb sustainability credentials through the production of a proven high quality biogas bi- product available for power and heat generation, and no odours in operation or in effluent.

How HyVAB works in two steps

  • In the bottom of the reactor (the first step) is an anaerobic biological reactor, where 75% of the organic waste is converted into methane gas.
  • At the top level of the tower (the second stage) is a new type of aerated biofilm reactor which utilises Biowater’s CFIC® process. This consumes the remaining organics and odorous gases that emerge.

Partner of choice

Biowater support customers from the earliest project stages through to handover and service agreements. Early partnering services include sampling and analysis to understand the specific waste water qualities, and pilot trials using our innovative containerised pilot HyVAB plants.
We will guide you through the process from start
to finish:

  • Upgrade existing plants.
  • Greenfield plants.T
  • Training/education.
  • Sampling and pilot studies
  • Operational cost analysis
  • Process selection
  • Service, maintenance and optimisation

CONTINUOUS IMPROVEMENT AND TotEx

The HyVAB design is always improving to keep our technology state of the art and to continuously offer improving value to our customers. Ongoing research and development, and pilot trials for complex non- routine applications/industries maintain the HyVAB as the most advanced ultra-high rate waste water treatment solution.

Specific ongoing trials are optimising HyVAB for:

  • Municipal Treatment
  • Pharmaceutical Industry
  • Tobacco Industry.
  • Oil Industry
  • Combination with tertiary treatment.

Highlights

  • Suitable for a wide range of industrial applications.
  • COD removal of over to 95% achievable.
  • Significant reduction in sludge production (80%) compared to other state of the art technologies, can allow zero desludge.
  • The technology can realize Zero Energy Use and even a Positive Energy generation.
  • High concentration methane (up to 84%) in generated biogas, perfect for energy generation.
  • Performance – Improves biological treatment which makes membranes perform more efficiently.

CFIC® – The next generation MBBR biofilm technology.

Biowater’s proprietary CFIC® technology offers industry-leading performance when compared with widely used Activated Sludge and MBBR solutions. The small footprint, combined with Biowater’s approach to process design makes this far more versatile than existing solutions, making it very suitable for a wide range of existing WWTP.

How it works

CFIC® reactor contains highly packed biofilm carriers to a degree (typically 90-99% bulk volumetric fill) that little movement of the carriers occurs in the reactor during normal operation. Microorganisms in the biofilm that attach on the surface of the carriers take up pollutants as food for growth.

The CFIC ® process has continuous inflow to the bioreactor and intermittent cleaning, using influent wastewater, which removes excess biomass (sludge) from the biofilm carriers.

Highlights

  • Energy Savings – Substantial reduction in energy consumption.
  • Reuse – Recycling of water and wastewater for reuse.
  • Effluent Quality – Superb effluent quality.
  • Low Capital Costs – Reduction in capital costs by reducing the size of the membrane or tertiary treatment.
  • Flexible – Upgrade an existing SBR, MBR or MBBR to provide additional capacity.
  • Performance – Improves biological treatment which makes membranes perform more efficiently.

About Fixed Film Technology

The basis of our CFAS® biofilm technology is the biological growth on polyethylene pieces called media or carriers. these surfaces provide a protected room for the biology to grow. the biofilm can handle extremely high loading conditions without any problems with clogging or shock.

Biowater’s CFAS® (IFAS) solution represents a key technology for winning strategic deals now and in the near future.

Highlights

  • Compact – doubles the capacity of an existing activated sludge plant. For new plants the carbon footprint is very small. For retrofits existing tanks can be used.
  • Flexible – bod, nitrogen and phosphorus removal can be included.
  • Stable – self regulating biofilm ensures stable treatment under variable loads. no clogging
  • Sludge Production – produces sludge with low sludge volume index. this is efficient for following separation and sludge treatment process.
  • Low capital costs – the installation is based on traditional technical equipment.
  • Complete System Supply – We offer system complete with biofilm carriers, aeration sieves, mixing, tanks as well as any tertiary treatment or additional equipment to suit the design.

The process

The BioWater CMFF® biological process is based on the MBBR (Moving Bed Bio Reactor) concept where moving plastic carriers with fixed biofilm remove organic and inorganic substances in the water. The proposed BioWater CMFF® design includes the Biowater biofilm carrier elements which are freely mixing around in the reactor and are specially designed for biofilm growth.

The bacteria will grow and develop a solid biofilm on the large protected surface area. The moving pattern of the carriers in the reactors will also provide a natural removal of excess biofilm, due to the shear forces between the carriers and the water in the reactor.

A well developed biofilm can handle an extremely high load of nutrients while avoiding problems associated with clogging or shock.

Highlights

  • Upgrade of existing activated sludge plants to achieve nitrification.
  • Compact – Doubles the capacity of an existing Activated Sludge plant. For new plants the footprint is very small. For retrofits existing tanks can be used.
  • Flexible – BOD, Nitrogen and Phosphorus removal can be included.
  • Stable – Self regulating biofilm ensures stable treatment under variable loads. No clogging.
  • Sludge Production – Produces sludge with low sludge volume index. This is efficient for following separation and sludge treatment processes.
  • Low Capital Cost
