Submersible Jet Aerator Pump — Waste Water Aeration & BOD Reduction for ETP/STP
High-efficiency submersible jet aerator pumps for waste water treatment aeration, MLSS mixing, and BOD level reduction. Available from 1 HP to 7.5 HP. Trusted by ETP and STP operators across India since 2002.
About Submersible Jet Aerator Pumps
Flow Chem submersible jet aerator pumps are engineered for efficient waste water aeration in effluent and sewage treatment plants. Designed and manufactured at our ISO 9001:2015 certified facility in Gujarat, these pumps combine pumping and aeration in a single submerged unit.
The jet aerator draws liquid from the aeration tank and forces it through a specially designed nozzle, creating a pressure drop that draws in atmospheric air. The air-liquid mixture creates fine bubbles distributed throughout the tank, providing high oxygen transfer rates — more efficient than surface aerators.
Available from 1 HP to 7.5 HP, Flow Chem jet aerators are suitable for ETP and STP plants of various sizes. Submerged operation reduces noise, making them ideal for plants near residential areas.
Key Features
Purpose-built for high-efficiency aeration in waste water treatment plants
Combines pumping and aeration in a single submerged unit. High-velocity jet nozzle draws in atmospheric air and creates fine bubbles for superior oxygen transfer throughout the entire tank depth.
Double mechanical seals with oil chamber protect the motor during continuous submerged operation. Pressure-tested before dispatch for reliable performance in demanding aeration applications.
Submerged operation significantly reduces noise compared to surface aerators. Suitable for ETP and STP plants located near residential areas, hospitals, and commercial zones.
Jet action creates circulation patterns that keep mixed liquor suspended solids uniformly distributed. Prevents solids settling and maintains active biological treatment throughout the tank.
Higher oxygen transfer rate per kWh compared to surface aerators. The submerged jet distributes oxygen at all tank depths, reducing total energy consumption for the same BOD reduction.
Premium-grade cast iron construction for durability in corrosive waste water environments. IP68 protection rating ensures reliable submerged operation in ETP and STP tanks.

Applications
Flow Chem jet aerator pumps serve critical aeration needs across India's treatment plants
ETP Aeration
Effluent treatment plant aeration tanks. Provides oxygen for biological treatment processes. High oxygen transfer rate reduces treatment time and improves effluent quality.
STP Aeration
Sewage treatment plant aeration basins. Maintains dissolved oxygen levels for aerobic bacteria. Replaces surface aerators with submerged, energy-efficient alternative.
MLSS Mixing
Mixed liquor suspended solids mixing in aeration tanks. Jet action creates circulation patterns that keep solids uniformly distributed throughout the tank volume.
BOD Reduction
Biochemical oxygen demand reduction in industrial and municipal waste water. Efficient oxygen transfer supports aerobic bacteria that break down organic pollutants to meet discharge standards.
CETP Aeration
Common effluent treatment plant aeration for multiple industries. Suitable for continuous duty in large-scale aeration basins handling mixed industrial effluent streams.
Equalization Tanks
Aeration and mixing in equalization tanks to prevent septic conditions. Maintains uniform waste water characteristics before biological treatment processes.
Jet Aerator vs Surface Aerator: Which Is Right for You?
Choose the right aeration technology for your treatment plant
Submersible Jet Aerator
Best for: Deep tanks, energy-efficient aeration, and plants near residential areas.
Operates submerged, distributing fine bubbles throughout the entire tank depth for maximum oxygen transfer. Lower noise, lower energy per kg O₂ transferred. Combined aeration and mixing eliminates the need for separate mixers.
Typical uses: ETP aeration, STP aeration basins, MLSS mixing, CETP plants, equalization tanks.
Surface Aerator
Best for: Shallow tanks and open lagoons where surface agitation is sufficient.
Oxygenates only the top layer of water. Higher noise levels. Lower oxygen transfer efficiency for deep tanks. May require separate submersible mixers for MLSS suspension in deeper basins.
Typical uses: Shallow oxidation ponds, aerated lagoons, small-scale STP plants with tank depth under 2 meters.

Frequently Asked Questions
What is a jet aerator pump used for?
A jet aerator pump is used in waste water treatment plants (ETP and STP) to add oxygen to the treatment process. It also mixes the tank contents to keep solids in suspension. Flow Chem jet aerators help reduce BOD levels and maintain uniform MLSS concentration.
How is a jet aerator different from a surface aerator?
A jet aerator operates submerged in the tank, creating fine bubbles throughout the entire water depth for higher oxygen transfer efficiency. Surface aerators only oxygenate the top layer. Jet aerators are also quieter and more energy-efficient for the same oxygen transfer rate.
What is BOD reduction in waste water treatment?
BOD (Biochemical Oxygen Demand) reduction is the process of removing organic matter from waste water using aerobic bacteria. These bacteria need oxygen to break down organic pollutants. Flow Chem jet aerator pumps provide this oxygen efficiently, reducing BOD levels to meet discharge standards.
What HP range is available for Flow Chem jet aerators?
Flow Chem jet aerators are available from 1 HP to 7.5 HP in three-phase configuration. Model selection depends on tank volume, BOD load, and required oxygen transfer rate. Contact our engineering team for free aerator sizing assistance.
Do you provide installation services for jet aerators?
Yes, Flow Chem provides professional aerator installation services across India. Our team handles site assessment, tank preparation, aerator installation, electrical connections, commissioning, and operator training.
