X-Flow

Xiga

Xiga modules are based on hydrophilic hollow-fiber ultrafiltration membranes, composed of a PES/PVP blend. The membranes are operated in a dead-end mode and their high mechanical and chemical strength makes them suitable for a wide range of applications. The pressurized membrane modules with inside-out configuration are the industry’s choice for the removal of bacteria, viruses, suspended solids, and colloids.

Functional Description

capillary ultrafiltration 


General
Xiga membrane modules can be operated at elevated presures for inline operations with RO, making use of GRP pressure vessels.

Key specifications
  • Temperature range: 0-40°C
  • Maximum operating pressure: 8 bar

Features
  • Backwashable and CEB


Fields of application

Potable water production 

The Xiga membrane modules provide superior separation and effective rejection of viruses and chlorine resistant organisms such as Cryptosporidium and Giardia in the production of drinking water.

Process water production

The Xiga membrane modules present an effective barrier to suspended solids and silt.
The permeate can be used directly as process water or, if salinity and dissolved solids are not within the required limits, be fed to a downstream RO system.

Effluent polishing

The Xiga membrane modules are a reliable solution to meet the highest standards for turbidity and microbiology. The polished effluent is ready for unrestricted high-grade reuse.
