Pall Aria™ AP-Series Water Treatment Systems are specifically designed to meet the drinking water treatment requirements of small communities. Pall Aria systems use uniquely designed Microza* membrane modules in a hollow fiber configuration to remove the following contaminants from surface and ground water sources:
- Turbidity
- Bacteria
- Cysts and Oocysts
- Iron and Manganese
- Arsenic
Each 0.1µm hollow fiber module provides high active surface area (538ft2 - 50m2). The hollow fiber modules in the Pall Aria system are highly permeable resulting in high water production rates.
Pall’s dedication to simplified process design and control logic has produced a family of systems that are characterized by:
- Full System NSF 61 Certification
- Long Service Life Hollow Fiber Membranes
- Operator Friendly Control Interface
- Simple Clean-In-Place Operation
- High Recovery
- Low Cost of Operation
- Easily Installed Modular Skids
- Compact System Footprint
- ISO 9000 Certified Manufacturing
- Optional Auxiliary Equipment

Performance
Pall systems with Microza membrane modules have been approved for potable water supply. The Aria hollow fiber membrane system was the first to receive a “full system” certification in accordance with ANSI / NSF 61 Specifications.
Extensive testing has been done across the USA including:
- University of New Hampshire
- Croton Reservoir, NY
- Highland Reservoir, PA
- Meeteetse Reservoir, WY
- Oregon Parks Department
- North Slope Borough WTP, AK
- Youngs River, OR
- Stoney Creek, VA
- Westover, PA
- Caney, KS
- Kernville, CA
- Basalt, UT
- Crested Butte, CO
- Hobart, NY
Site testing confirmed Pall Aria Water Treatment Systems meet or exceed EPA standards for safe drinking water, such as the requirement of the Surface Water Treatment Rule (as amended December 16, 1998).
