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.

Features
- Removal of microorganisms
- 99.9999% (LOG6) reduction of bacteria (Pseudomonas diminuta)
- 99.99% (LOG 4) reduction of viruses (MS2 coliphages) by mechanical means (EPA Est. No. 090374-NLD-001)
- High membrane packing density: The industry’s smallest free volume in a membrane module
- 100% integrity testing on individual fibers
- Individual fiber repair
- Very good antifouling behavior
- Typical permeate quality:
- SDI < 3
- Turbidity < 0.1NTU
- Excellent chemical resistance with a wide pH range (2 – 12) and high chlorine stability (maximum free chlorine 250 mg/l)
- Typical high permeability: low energy consumption
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.

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.
