HDPE MBBR BIOFILTER MEDIA
PRODUCT OVERVIEW
HydroNovus HDPE MBBR media provides protected surface area for attached-growth microorganisms in moving bed biofilm reactor systems. The carriers remain in continuous motion under aeration or mechanical mixing, helping biological treatment operate within a compact reactor volume. Multiple carrier geometries are available for municipal wastewater, industrial effluent, packaged plants, and recirculating aquaculture systems.
CORE FEATURES
• Virgin HDPE construction for stable density, impact resistance, and long-term operation.
• Protected internal channels support biofilm attachment while limiting excessive shear.
• Multiple sizes and geometries allow selection for carbon removal, nitrification, or combined treatment.
• Suitable for new MBBR systems and upgrades of existing activated-sludge tanks.
• Easy bulk handling; no fixed media frame is required inside the biological reactor.

• IFAS and hybrid biological treatment processes
SELECTION INFORMATION
For model selection, please provide daily flow, influent and target COD/BOD, ammonia and total nitrogen, wastewater temperature, existing tank dimensions, available aeration capacity, and the planned process. HydroNovus can then recommend the carrier model, filling volume, retention screen, and preliminary aeration demand. Final biological design should be confirmed by the project engineer.
FREQUENTLY ASKED QUESTIONS
Q: Which MBBR model should I use?
A: The correct model depends on the treatment objective, organic and ammonia loading, reactor volume, wastewater temperature, and required biofilm protection. Surface area alone should not be used as the only selection criterion.
Q: Can MBBR media be added to an existing aeration tank?
A: Often yes. A retrofit normally requires hydraulic and biological checks, media-retention screens, sufficient mixing, and adequate oxygen transfer.
Q: How long does biofilm formation take?
A: Start-up time varies with temperature, wastewater characteristics, seeding, dissolved oxygen, and operating conditions. Performance should be evaluated through water-quality trends rather than a fixed number of days.
Q: Can you provide samples and model data?
A: Yes. Samples, model dimensions, packing density, and technical datasheets can be supplied for project evaluation.
