Aqua MultiBore®
Ceramic & Polymeric Membranes

Multibore tubular ultrafiltration membranes in two series: C-Series (ceramic — maximum durability and chemical/thermal resistance) and P-Series (polymeric — high performance with better cost-effectiveness). The ideal solution for every quality, capacity, and operating condition requirement.

C-Series vs P-Series — Right choice for every project

C-Series — Ceramic

  • Service life exceeding 15 years
  • Full pH 1–14 resistance
  • High-temperature tolerance
  • More aggressive chemical cleaning possible
  • Ideal for complex industrial effluents
  • Lower module replacement frequency

Multibore tubular membranes — the evolution of ultrafiltration

MultiBore® technology was developed to overcome the limitations of conventional single-channel tubular membranes. Each module contains multiple parallel channels (7 channels per membrane in the standard geometry), which better distributes mechanical forces and significantly increases structural robustness — eliminating the main failure mechanism of conventional hollow fibers: pressure-induced collapse.

The multibore geometry also maximizes filtration area per module and allows high backwash fluxes without collapse risk, guaranteeing longer life and operational reliability. Available in two series to address everything from municipal wastewater treatment to highly chemically and thermally aggressive industrial applications.

Multibore Geometry — More Robust

7 parallel channels distribute mechanical forces and eliminate collapse risk during backwashing.

Absolute Physical Barrier

0.02–0.04 μm pores retain 100% of solids, bacteria, viruses, and protozoa — regardless of load variations.

Configuration Flexibility

Scalable modules in external racks or integrated with MBR systems — adaptable to any capacity.

How do MultiBore® membranes work?

Pressurized effluent enters through the tubular channels of the MultiBore® modules. Transmembrane pressure (TMP) forces the liquid through the UF pores, retaining all solids, colloids, bacteria, and protozoa in the lumen. The permeate collected externally is sent to subsequent stages.

Membrane cleaning is performed through regular backwash cycles (reverse permeate flow) and relaxation (filtration pause with aeration), plus periodic chemical cleaning (CIP) with acid or alkali based on identified fouling. The multibore geometry supports high backwash fluxes without membrane damage risk, ensuring complete flux recovery.

1. Inside-Out Filtration

Effluent enters tubular channels; permeate collected externally after passing through UF pores.

2. Periodic Backwash

Reverse permeate flow removes fouling — multibore geometry supports high intensity without damage.

3. Automatic CIP

Programmable chemical cleaning restores original membrane flux maintaining designed service life.
