Technology
Microporous ceramics engineered for gas and liquid
The same rigid ceramic structure can either disperse gas into fine bubbles or separate fine solids from liquids, depending on pore size and duty.

Alumina and silica ceramic structure
A rigid alumina- and silica-based ceramic body carries a controlled network of fine pores. The pore size is engineered to suit either aeration or filtration duty.
Fine-bubble aeration
Compressed gas passes through the ceramic surface and disperses into fog-like microbubbles 0.05–0.5 mm in diameter. At 1 m water depth the standard oxygen transfer efficiency is 35%, rising 5–8% with each additional 0.5 m of depth.
Pressure and depth capability
Aeration plates withstand up to 0.7 MPa and can operate in liquids less than 60 m deep. They begin working above 20 kPa, allowing use with high-pressure oxygen where no power is available.
Corrosion resistance and flexible assembly
Ceramic surfaces resist seawater corrosion and UV exposure. Quick-twist fittings simplify installation, and plates can be used individually or combined to match the aeration zone.
Nano-scale filtration
Ceramic membrane discs are produced with pore sizes as fine as 50 nm, separating fine solids from liquids in rotary disc filters with a compact filtration footprint.
Operation & maintenance
Designed for straightforward field maintenance
Routine surface cleaning
Use a hard nylon brush (never a metal brush) or high-pressure water to remove deposits from the ceramic surface.
Optional acid wash
For stubborn blockage, a diluted hydrochloric acid wash not exceeding 10% concentration can be used, followed by a clean-water rinse.
Pressure and flow
Aeration plates begin operating above 20 kPa and withstand up to 0.7 MPa for liquids less than 60 m deep.
Corrosion awareness
Ceramic surfaces resist seawater corrosion and UV exposure, with aluminum-alloy and engineering-plastic base options.
