· Advantage

Small Boss

🔶Fully Open External Design

Unlike closed wheel-type carriers, the spiral open structure creates turbulent micro-currents inside the carrier. This ensures oxygen and nutrients reach every biofilm layer — biofilm-to-surface distance is only 0–3 mm across the entire media.

🔶Clog-Resistant & Self-Cleaning

The open geometry prevents debris accumulation and biofilm overgrowth blockage. Ideal for high-TSS wastewater, scaling-prone environments, and industrial applications where conventional media fails.

🔶Superior Oxygen Transfer Efficiency

Patented double-roll airflow design generates optimized air-water mixing patterns. Achieves higher oxygen utilization with lower aeration energy — reducing OPEX for plant operators.

🔶Rapid Biofilm Colonization

Hydrophilic surface treatment and trace element integration enable biofilm attachment within 3–15 days. Proven by academic research with Anammox and nitrifying bacteria — stable colonization from day 85 in deammonification systems.

🔶Shock Load Resilience

The protected internal surface area maintains biofilm integrity during hydraulic surges and toxic shock events. Short recovery time after upset conditions — critical for industrial wastewater with variable influent quality.

🔶Versatile Process Compatibility

One carrier, multiple processes: Aerobic MBBR, IFAS hybrid, Anoxic denitrification, Anaerobic treatment. Works in municipal, industrial, aquaculture RAS, and groundwater remediation applications.

See the difference open structure makes

Feature	Spiral Open Structure	Wheel-Type (K1/K3 Style)
Structure	✅ Fully open — no dead zones	⚠️ Closed wheel — internal dead zones
Clogging Risk	✅ Extremely low — self-cleaning	⚠️ Moderate — prone to biofilm overgrowth
O₂ Transfer Efficiency	✅ Superior — 0–3 mm biofilm distance	⚠️ Limited — deeper biofilm layers
High-TSS Tolerance	✅ Excellent — open flow paths	⚠️ Can trap solids internally
Aeration Energy	✅ Lower — better airflow design	⚠️ Higher mixing energy needed
Shock Load Recovery	✅ Fast — protected biofilm retains	⚠️ Slower — biofilm can slough off

· FAQ

Small Boss

🔶What makes this different from K1/K3 carriers?

A: The spiral open structure eliminates internal dead zones where biofilm overgrows and clogs conventional wheel-type carriers. Aqwise's original design provides superior oxygen transfer, self-cleaning action, and 30%+ more effective surface area.

🔶What is the minimum order quantity (MOQ)?

A: 1 m³ for sample/trial orders. Standard orders start from 5 m³ with volume pricing available for 20+ m³.

🔶What is the typical lead time?

A: 7-10 days for standard orders. 15-20 days for custom specifications. We maintain 230+ m³/day production capacity.

🔶Do you provide free samples?

A: Yes. We provide free 1-2 kg samples with technical datasheet. Customer covers shipping cost only.

🔶What fill ratio should I use?

A: Typical fill ratio is 30-50% depending on application. Municipal: 40-50%. RAS aquaculture: 30-40%. Industrial: 35-50%. Our engineers can calculate the optimal ratio for your specific project.

🔶How does the 10-year warranty work?

A: We guarantee structural integrity for 10+ years under normal operating conditions (5-45℃, pH 5-10). The HDPE material is UV-stabilized and resistant to biological degradation.
