Generation principle

Porous membrane. Gas–liquid contact.

Gas crosses the porous membrane and water flow detaches the bubbles.

Gas crosses a porous membrane. Flowing water detaches the bubbles and carries them into the process. We select flows, gas and pressures for each application.

Nanobubbles are gas bubbles below 1 µm in diameter. At equal gas volume, reducing the diameter increases the interfacial area available for transfer.

Parameter	Selection basis
Model identification	GENESIS^™ NB-XX: numeric reference defined in the proposal.
Generator flow rate	Stated range: 1–100 m³/h. In a sidestream, this is not the total plant flow.
Process gases	Air, O₂, O₃, CO₂ and N₂; materials and configuration depend on the gas and water.
Energy and utilities	No motor in the core. System consumption includes pumping, gas compression or generation, and controls.
Gas pressure and flow	Defined for the model, backpressure and gas. The gas–liquid pressure margin is checked.
Water quality	Review of abrasive solids, particle size, viscosity, salinity, temperature and chemical compatibility.

Process interfaces

Three ways to connect to your plant.

Inline

Water passes through the module before the next treatment stage.

Sidestream

A sidestream treats part of the flow and returns it to the process.

Tank recirculation

Take-off and return within a contact tank or reactor.

Process gases and service requirements

Air and oxygen for oxygenation and process trials; ozone for an engineered oxidation stage; CO₂ for carbon transfer or pH control; N₂ for specific applications.

Ozone service requires designed contact, off-gas destruction, ventilation and interlocks. Anaerobic digestion requires a specific gas selection; air or oxygen is not introduced by default.

GENESIS^™ applications

One technology. Multiple processes.

DAF, coagulation and flocculation

Optimise chemicals and solids capture

Integration during conditioning upstream of flotation to assess interaction between bubbles, particles and flocs. The objective is to improve separation while maintaining effluent quality with optimised dosing.

Initial gas selection: Air
Integration criterion: Assessed together with the existing saturation and flotation system; nanobubbles alone do not replace flotation.

Aerobic biological reactors

Increase oxygenation capacity

Oxygen supply in reactors and sidestreams to support biomass activity. It can be assessed as additional capacity during peak loads or where oxygen transfer is limited.

Initial gas selection: Air or oxygen
Integration criterion: Reactor mixing and actual oxygen demand remain part of the design.

Membranes and CIP cleaning

Restore permeability and optimise cleaning

Application in cleaning trials or at compatible process points to assess fouling development and permeability recovery. Particularly relevant to organic and biological deposits.

Initial gas selection: Air, subject to compatibility
Integration criterion: Membranes, materials and fouling type determine the protocol. Replacement of cleaning chemicals is not assumed.

Ozone and advanced oxidation

Improve ozone utilisation

Ozone dispersion in water as part of an oxidation stage. The objective is to improve utilisation within a process designed for the target contaminant and water quality.

Initial gas selection: Ozone, with compatible materials
Integration criterion: The design includes contact time, off-gas treatment and by-product checks where appropriate.

Anaerobic digestion and biogas

Explore improvements in biogas production

Application under development

An evaluation pathway for studying the effects of gas transfer and substrate conditioning on anaerobic processes. Gas and dosing are selected for each reactor.

Initial gas selection: Trial-specific selection
Integration criterion: Microaeration requires a specific design: indiscriminate air or oxygen addition can impair digestion.

Sludge conditioning

Optimise polymer use and sludge separation

Trials upstream of thickening or dewatering to assess changes in polymer response and solid–liquid separation.

Initial gas selection: Air, subject to process requirements
Integration criterion: Results depend on sludge characteristics and mixing energy; comparison under equivalent conditions is required.

Irrigation and hydroponics

Increase oxygen availability at the roots

Oxygenation of irrigation water and nutrient solutions to improve oxygen availability in the root zone. Integration into tanks, recirculation systems and irrigation lines.

Initial gas selection: Air or oxygen
Integration criterion: pH, conductivity and nutrition control are maintained; the technology is adapted to the crop and hydraulic system.

Aquaculture and RAS systems

Stabilise oxygen in recirculation

Oxygen supply in tanks and recirculation loops to help meet the demand of the organisms and biological treatment.

Initial gas selection: Air or oxygen
Integration criterion: Supersaturation and dissolved-gas control form part of the design for each species and stocking density.

Lakes, ponds and surface water

Address oxygen deficits

Oxygenation of water bodies to support biological balance and address oxygen deficits. Sizing considers volume, depth and organic load.

Initial gas selection: Air or oxygen
Integration criterion: External nutrient loading must also be managed; oxygenation alone does not guarantee algae removal.

Washing and food processes

Optimise wash water and recirculation

Integration into wash water and recirculation circuits to assess surface cleaning and water use. Ozone use requires a validated disinfection protocol.

Initial gas selection: Air, oxygen or ozone according to the process
Integration criterion: Food compatibility and process requirements are verified. Air or oxygen does not constitute validated disinfection.

Industrial circuits and cleaning

Support fouling control

Evaluation as a support measure for controlling soft deposits, biofilms and cleaning operations in compatible circuits.

Initial gas selection: Selection based on materials and objectives
Integration criterion: Required chemical and microbiological treatment is retained until an effective alternative has been demonstrated for the circuit.

Oil and mineral separation

Improve gas–particle interaction

Assessment of gas–particle interaction to support fines recovery, oil separation and other flotation operations in process water.

Initial gas selection: Air or another compatible gas
Integration criterion: Testing uses the actual water composition: particle size, salinity, oils and surfactants affect the response.

Value for your plant

Oxygenation, conditioning or cleaning to match the application.

Integrate flexibly

Net savings depend on the process, pumping, gas supply and maintenance. We size the complete system for your plant conditions.

Engineering questions

Before specifying the equipment.

Does the generator use electricity?

The core has no motor or moving parts. The system requires water flow and gas at design conditions, so pumping and gas supply must be included. It is not a zero-energy system.

Can it be integrated into an existing plant?

Yes. It can be connected inline, in a sidestream or in a tank recirculation loop. Selection depends on flow, available pressure, gas and the water contact point.

Does it replace DAF microbubbles?

Integration is proposed before coagulation or in pre-contact to assess conditioning. Flotation still requires its microbubble lifting mechanism and saturation circuit according to the DAF design.

What maintenance is required?

Monitor pressures and flow rates, gas quality and transfer performance. Cleaning depends on the water and material compatibility. Shutdown and storage instructions are provided for the selected model.

What information is needed for a proposal?

Application, plant and available loop flow, water analysis, temperature, pH, pressure, gas and objective. A P&ID or sketch helps identify the connection point and required utilities.
