Crossflow XL

Developed for heavy-duty applications such as produced water treatment or oily wastewater streams, Crossflow XL separates clean water from high solids streams (more than 1,000 ppm) and removes oil from water by applying hydrophilic PVDF tubular membranes. Crossflow XL skids are typically built for large-scale solutions.

Features

  • Ability to deal with high temperatures (0-60C) 
  • Compact footprint, standard 40 ft high cube container
  • High chemical resistance and mechanical strength 
  • Robust system & simple layout and process
  • For large capacitities (up to 250 m3/h)
  • Up to 95% recovery
  • Feed oil up to 300 PPM


typical use

The Crossflow XL skids are mainly used for industrial wastewater streams with oil content and produced water applications. The X-Flow Compact 75G module was especially developed for such demanding tasks, and applies X-Flow Helix technology to counter fouling and enhance flux rates. The high-strength GRP membrane housings have flange connections on both the feed and permeate side, and high chemical resistance.


 In produced water applications, the produced water can be reused as injection water in just three steps (UF membranes, activated carbon, RO).

In contrast to the complex conventional options, this simplified process provides a smaller footprint, less weight, a lower OPEX and a higher permeate quality. 

scope

Crossflow XL is a unique membrane concept to treat wastewater, such as produced water, with oily content. With carefully selected partners, Pentair develops innovative and ready-to-use membrane installations that meet both regulatory and financial KPIs. The Pentair scope consists of the modular skid concept, X-Flow tubular membranes, engineering, commissioning and process optimization.


As one of the world’s foremost membrane technology knowledge centers, we share our scientific know-how and practical experience with our partners to make the difference in challenging filtration projects. Our unique services during start-up and commissioning ensure a properly functioning membrane solution that will beat expectations.


Fields of application

Crossflow XL is used in applications such as water injection and re-injection, steam assisted gravity drainage (SAGD) and Enhanced Oil Recovery (EOR) or Chemical Enhanced Oil Recovery (CEOR).

The robustly designed Crossflow XL skids are available in four sizes: 1x8 modules, 2x8 modules, 3x8 modules and 4x8 modules, with performances ranging respectively from approximately 50 to 100, 150 and 250 m3/h. 

For capacities under 50 m3/h the Crossflow MBR can be considered.
