HOW
FLOWGATE
WORKS
A self-clearing aeration and gas-liquid mixing platform built for fluids that clog, foul, or overwhelm conventional systems.
FlowGate combines a proprietary multi-channel nozzle, a Churn Chamber, and a large-diameter air inlet to deliver powerful oxygen transfer, vigorous mixing, and reliable operation in demanding fluid systems.
SELF-CLEARING DESIGN
Channel geometry promotes exchange while resisting clogging, fouling, and debris buildup.

AIR INLET
Large-diameter, low-backpressure inlet maintains reliable gas delivery in harsh, high-solids environments.

CHURN CHAMBER
Creates vigorous gas–liquid churning that keeps solids suspended and enhances oxygen transfer.
FLOWGATE NOZZLE
Engineered multi-channel flow passages create
high-shear, high-entrainment gas–liquid mixing.
THE OPERATING PRINCIPLE
Air Enters
Gas is delivered into the lower chamber through a large diameter inlet

Churn Forms
A vigorous internal churn regime forms inside the chamber

Bidirectional Exchange
Gas-loaded liquid ejects outward while surrounding fluid refills through self-clearing channel paths
Vessel-Scale
Mixing
The repeated exchange drives oxygen transfer, solids suspension, and tank circulation.
EFFICIENCY ADVANTAGE
LOW-PRESSURE, HIGH-VOLUME AIRFLOW
FlowGate is designed to move large volumes of air at low operating pressure. When properly configured, the aerator creates negative dynamic wet pressure relative to static hydrostatic head, reducing the backpressure felt by the blower once the system is running.
This allows more blower energy to drive useful gas–liquid contact, circulation, and mixing instead of being lost to diffuser restriction, fouling, and heat.
-
High-volume blower operation
-
Reduced blower backpressure
-
More energy driving circulation and mixing
Technical note: The amount of pressure reduction varies with nozzle size, channel geometry, airflow, depth, churn chamber configuration, viscosity, solids loading, and installation layout. Because this pressure drop affects fluid levels and transfer behaviour, FlowGate systems are configured around it during design.
WHY FLOWGATE IS DIFFERENT
NO DELICATE FINE-PORE DIFFUSERS
Engineered channels resist clogging and perform in conditions that foul other systems.
NO MOVING PARTS INSIDE THE VESSEL
Fewer failure points and less maintenance. Built for continuous operation.
BUILT FOR DIRTY, FIBEROUS, HIGH SOLIDS FLUIDS
Designed for the harsh realities of wastewater, industrial, and organic process streams.
DESIGNED FOR RELIABILITY AND REAL-WORLD OPERATION
Simple by design. Proven by performance in the most challenging applications.
DEVELOPED IN THE REAL WORLD
FlowGate emerged from years of work on high-solids aerobic bioreactors, where conventional diffusers, pumps, and screening approaches repeatedly clogged, fouled, or failed.
The result is a more robust aeration platform built from real operating problems—not theory alone.
