Pall Aria AP-Series Water Treatment Systems are specifically designed to meet the drinking water treatment requirements of small communities. Aria systems use uniquely designed Microza* membrane modules in a hollow fiber configuration to remove the following contaminants from surface and ground water sources:
Cysts and Oocysts
Iron and Manganese
Each 0.1μm hollow fiber module provides high active surface area (538ft2 - 50m2). The hollow fiber modules in the 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
Low Cost of Operation
Easily Installed Modular Skids
Compact System Footprint
ISO 9000 Certified Manufacturing
Optional Auxiliary Equipment
*Microza is a trademark of Asahi Kasei Corporation.
Standard system components consist of 1 to 60 membrane modules, a feed tank, one feed pump, one reverse filtration pump, manual on/off and automatic valving, filtrate flow meter, pressure and temperature sensors, and PLC control.

Microza membrane systems 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
Crested Butte, CO
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).
