Choosing the Right Packing Media: Ceramic, Plastic & Metal
Ceramic packings offer excellent corrosion and heat resistance at a low cost,
with good wetting performance—but they’re brittle.
Plastic packings (usually polypropylene) are lightweight,
tough, and corrosion‐resistant, though surface wetting is poorer without treatment.
Metal packings (carbon steel, stainless, titanium)
vary by corrosion risk and cost: use carbon steel where corrosion is low,
stainless for stronger resistance,
and specialty alloys only in extremely aggressive conditions.

Porous Spherical Suspended Packing
Also called rotary porous spheres,
this latest generation of biofilm carriers features a fully 3D structure
and huge surface area. Simply drop them into bioreactors
no supports needed—and enjoy easy film formation without clogging.

High-Efficiency Aerators
Aerators supply oxygen and mix water in wastewater processes.
Our units use imported, abrasion-resistant membranes
with extra thickness for higher oxygen transfer
and a robust tray design for long-lasting performance.

Preventing Aerator Clogs: Cleaning Tips
Keep aerators running smoothly by cleaning regularly—
either with controlled‐concentration formic acid or gentle,
high-pressure air bursts.
Always monitor acid strength
and air volume to protect equipment and operators.

Aerator Maintenance Best Practices
Inspect your aeration system often:
rising head loss or odd bubble patterns mean deposits (salts, sludge) need removal.
Clean membranes to restore airflow,
boost oxygen efficiency, and reduce pressure loss.

Diffuser Specifications
Our disc diffusers come in two shapes—curved
and flat—and two materials: rubber and silicone.
Silicone offers better elasticity, lower energy use,
and superior resistance to acids, alkalis, and aging,
making it perfect for industrial and high-salt processes.
Available in three sizes (215, 260, 300 mm) with varying air flows
and layout densities.
Factory customization available upon request.
