Product Advantages
◆
Small Phi 11 by 7 mm Format
The compact dimensions provide a high carrier count per unit volume for small RAS filters and compact treatment equipment.
◆
At Least 900 Square Meter Surface Area
The documented surface area supports higher biomass holding potential than lower surface area carriers of the same bulk volume.
◆
Aquaculture and Sewage Application Range
The model is listed for both aquaculture biofiltration and rural compact sewage treatment, simplifying selection across smaller systems.
◆
Fill Ratio from 15 to 68 Percent
The wide stated range gives the process designer room to balance treatment load, mixing energy and available reactor volume.
◆
Near Water Density
A specific gravity of 0.94 to 0.97 grams per cubic centimeter is suitable for moving bed suspension with a correctly sized aeration system.
◆
Traceable HDPE Specification
The carrier uses virgin HDPE and is specified against HG T 5924 2021 requirements in the supplied product data.
Application Scenarios
Aquaculture RAS Biofiltration
The Phi 11 by 7 mm format and documented surface area make PE02 a compact option for RAS biofilters after feed load and screen retention checks.
Rural Compact Sewage Treatment
PE02 can be evaluated for packaged village and community systems where reactor volume is limited and both BOD and ammonia design loads are known.
Small Scale Municipal Upgrade
The model may be considered for small aeration tank upgrades after verifying existing tank volume aeration capacity hydraulics and outlet screens.
Decentralized Wastewater Systems
The supplied application scope includes remote communities tourist facilities and industrial sites using decentralized treatment equipment.
Application Reference Gallery
The following photographs show real treatment and aquaculture environments relevant to this model category. Final media selection is based on influent data reactor volume target loading and operating conditions.

FAQ
◆
Why can PE02 be considered for compact systems
Its Φ11×7mm format and ≥900m²/m³ specific surface area provide a compact design basis, while the final reactor volume still depends on measured organic and ammonia loads.
◆
Can the same PE02 design be used for RAS and rural sewage
No. The carrier parameters are the same, but aquaculture and sewage systems use different loading, oxygen, solids and hydraulic design conditions. Each application requires its own calculation.
◆
What fill ratio is stated for PE02
The latest supplied parameter sheet states a recommended fill ratio of 15%-68%. Aeration, mixing, screen area and freeboard must be checked before choosing the operating value.
◆
What must be checked before a PE02 retrofit
Confirm existing tank volume, peak flow, oxygen transfer, outlet screens, mixing, current influent and target effluent before calculating media quantity.
