Tubular membranes are enforced tubes having an inside out filtration mode with the separating skin at the inside of the membranes. The new generation membranes have smart turbulence enhancing properties, driving the performance beyond the classical smooth membrane.

Helix flux enhancement

With the Helix flux enhancement, X-Flow addresses a bottleneck in high-solids ultrafiltration (UF) by preventing the build-up of foulants. Helix technology enhances flux, increases flow, and saves energy. By introducing turbulence right at the membrane wall, Helix technology provides continuous mixing and efficient removal of the cake layer that would otherwise reduce the membrane’s hydraulic permeability. The resulting higher permeate flow means higher productivity and lower costs. Due to the effective membrane cleaning at low crossflow velocities, Helix technology significantly reduces the energy footprint compared to standard tubular membrane solutions.

Helix technology sustains and boosts the productivity of membrane systems with helically winding ridges that provide turbulence and enhanced feed water mixing. The prevention of cake formation allows for higher permeate flows at lower crossflow velocities. This will result in:

  • Higher productivity: up to 100%
  • Lower energy consumption: down by 50% (depending on feed water quality).
