Product Advantages
◆
Honeycomb Chamber Geometry
Hexagonal internal cells provide multiple protected attachment zones within a Phi 25 by 4 mm carrier.
◆
At Least 1700 Square Meter Surface Area
PE79S has the second highest documented surface area in this 12 model range and the highest among the Phi 25 mm aquaculture models listed.
◆
Multi Directional Flow Paths
The honeycomb cell layout provides multiple routes for water movement through the carrier structure.
◆
Thin 4 mm Profile
The thin carrier profile increases piece count per bulk volume compared with thicker media of the same outside diameter.
◆
Fill Ratio from 15 to 65 Percent
The documented range supports different RAS loading levels after engineering checks for hydraulics, screens and mixing.
◆
Controlled HDPE Density
Hydrophilic modified HDPE with a specific gravity of 0.94 to 0.97 grams per cubic centimeter supports moving bed circulation.
Application Scenarios
Ultra Intensive RAS Systems
The honeycomb structure and documented surface area make PE79S a candidate for high load RAS design after full feed ammonia oxygen and hydraulic calculations.
High Value Species Farming
The model can be considered for species requiring tightly controlled water quality, with design based on actual feeding biomass and temperature data.
Compact High Capacity Biofilters
PE79S can support compact design studies, while final tank volume depends on usable protected area loading limits and operating conditions.
RAS Biofilter Retrofit Upgrade
Retrofit suitability requires confirmation of retention screens mixing head loss existing tank geometry and allowable carrier inventory.

FAQ
◆
What are the confirmed PE79S parameters
The latest supplied sheet states Φ25×4mm HDPE media, ≥1700m²/m³ specific surface area, 0.94-0.97g/cm³ specific gravity and a 15%-65% fill ratio.
◆
Does the highest surface area automatically mean the smallest reactor
No. Reactor volume also depends on usable area basis, allowable loading, oxygen transfer, temperature, hydraulics, solids and the required effluent quality.
◆
Can PE79S be evaluated outside aquaculture
It may be evaluated for engineered wastewater duty only after treatability, loading, mixing, screens and process conditions are confirmed. The carrier should not be selected from model name alone.
◆
What should be checked when replacing another carrier with PE79S
Check physical retention, bulk volume, mixing demand, hydraulic head loss, applicable surface area basis and biological loading before changing media.
