GET SPINNING WITH HELIX
In many parts of the world, water scarcity is a growing issue. In order to secure future access to reliable water sources, crucial reuse and filtration opportunities have to be seized today.
Upgrade your smooth tubular membranes with Helix for higher flux, lower costs and reduce chemical usage.
See how Helix can make a difference for you by looking at 3 real-life examples.

Dive into three performance comparison scenarios in our leaflet, that clearly demonstrate the remarkable improvements of Helix membranes over traditional smooth tubular membranes.
ADRESSING UF BOTTLENECKS
High-solids ultrafiltration (UF) faces bottlenecks due to foulant buildup, leading to reduced flux, lower flow, and increased energy consumption.
Helix tubular membranes:
- Introduces turbulence at the membrane wall: Continuous mixing removes the cake layer.
- Improves hydraulic permeability: Enhances flux and flow, increasing productivity and reducing costs.
- Lowers energy footprint: More efficient than smooth tubular membranes.
| Smooth Membranes | Helix Membranes | |
| Energy | High energy consumption due to high crossflow requirements. | Significantly lower energy usage. |
| Performance | Limited performance by fouling and insufficient flux rates. | Boosts productivity by increasing flux rates without extra energy consumption. |
| Cleaning | Frequent cleaning results in higher cleaning costs with required downtime. | Reduced cleaning frequency and associated costs. |
| Fouling | Prone to fouling, requiring frequent maintenance and downtime. | Resistant to fouling, resulting in limited downtime. |
| Sustainability | Higher chemical usage and energy consumption. | Ecofriendly, reducing chemical use and supporting sustainability goals. |
BENEFITS
- Retrofit easily to save on equipment and labor costs, with flexibility, minimal downtime, and maintained productivity.
- Increases productivity and lowers energy consumption
- Less downtime of wastewater plant due to fouling prevention capability.
- Trust our decades of industry experience for reliable, high-quality solutions.
CASE STUDY - PERFORMANCE COMPARISON
Pentair initially installed two units with six X-Flow Compact 27 membrane elements for leachate treatment. Six standard elements in one unit were replaced with Compact 27 Helix membrane elements. Flux increased from 135 lmh for standard Compact 27 to an impressive 180 lmh with the Compact 27 Helix membrane module. This results in energy savings of around 33 percent.
| Technology: | Crossflow MBR | |
| Crossflow velocity: | 3.5 m/s | |
| UF feed water: | 10 – 15 g/l MLSS | |
| Energy saved: | 33,3% |

“It is well-known that membranes are susceptible to quick caking. The dirt typically sticks to the membrane wall, resulting in a rapid productivity drop. Until now, this problem was usually solved by increasing the crossflow velocity. Put simply, the pressure is increased. However, this requires a lot of energy. The Helix technology addresses this issue by creating an eddy current inside the membrane, thereby causing the particles to not stick at all.”
