Bio-Mesh Bio-Block

Q: Should I use the 55 mm or the 42 mm tube?

The 42 mm gives more surface area per cubic metre (250 m²/m³ against 200 m²/m³), while the 55 mm has a higher 82% hollow space and copes better with dirtier water.

Q: How much surface area is in one module?

About 33 m² in a 550 mm 55 mm-tube module and about 41 m² in a 546 mm 42 mm-tube module, based on the published specific surface areas.

Q: How many modules do I need?

Divide the surface area your daily ammonia (TAN) load needs by roughly 33 m² or 41 m² per module — send us your flow, feed rate and tank dimensions and we will confirm the count.

Q: Does it need assembly on site?

No — modules arrive finished and self-supporting, and can be lowered straight into an existing tank or channel.

Q: How much ammonia will it convert?

The supplier does not publish a nitrification rate, and a rate without a temperature and TAN concentration is not usable — we size it from surface area and your feed load instead.

Q: How do I get a price?

Request a quote with your tube size, module count or tank dimensions, and application — we will come back with pricing, freight and lead time.

Product Information

Key Features

Fixed-bed tubular biomedia module in two tube diameters — 55 mm at 200 m²/m³ and 42 mm at 250 m²/m³
Rough-surfaced tubes give more area for biomass to build on and hold onto
Supplied as a finished 550 mm cube module — no on-site assembly, and it lifts straight into an existing tank
Manufactured in Australia from HDPE, and both chemically and biologically inert
High voidage — 60% for the 55 mm and 55% for the 42 mm — keeps head loss and blockage risk low
Suits trickling filters, aerated and submerged aerobic or anaerobic beds, oil separators, stormwater sumps and cooling towers
Long-term, low-maintenance media with no consumables — a one-off investment rather than a running cost
Choosing your tube size and module count: the 42 mm tube packs 250 m²/m³ and is the choice where surface area per cubic metre matters most; the 55 mm tube gives 200 m²/m³ but a higher 82% hollow space, so it suits dirtier water where blockage is the bigger risk. Each standard module holds about 33 m² (55 mm) or 41 m² (42 mm) of surface area, so divide the area your daily ammonia load needs by that figure to get the module count. Send us your flow, ammonia load and tank dimensions and we will confirm it.
