An efficient and cost-effective solution for water treatment in the food and beverage industry

Pall Aria™ FB membrane systems are specifically designed to meet the stringent water requirements of the food and beverage industry. The fully–automated, stainless teel system simplifies the traditional water treatment process, while ensuring increased protection of all downstream equipment. By providing constant and high quality water irrespective of raw feed water variance, food and beverage manufacturers can reduce their overall filtration costs at their production sites.

Pall Aria FB systems treat difficult water in food and beverage applications, reducing the water fees and cost-effectively replacing sand filters. Pall Aria FB systems utilize robust polyvinylidene fluoride (PVDF) hollow fiber microfiltration membranes to retain suspended solids and pathogenic microbes. The retained solids are concentrated in a low volume waste stream that is discharged from the system. The membranes are capable of handling high flux rates and are precisely packaged within a compact system footprint. Fully-automated, simple and easy to operate, the system is the solution of choice for high water quality production within the food and beverage industry.

Benefits

Pall has extensive experience in providing membrane solutions for municipal water treatment and is dedicated to advancing its technology to ensure simple and cost-effective solutions that achieve reliable process control. Pall Aria FB membrane filtration systems incorporate unique features which enable food and beverage plants to achieve high water quality at reduced operating costs (up to 50% compared to conventional treatment methods), while ensuring high microbiological process safety. These features include:

• Durable PVDF hollow fiber membranes produce consistent water quality, regardless of the raw water quality (within specified limits), for most typical water treatment applications
• Overall cost improvement
1. Low chemical consumption due to efficient mechanical backwash
2. Low energy consumption (typically 0.09 kWh per m³ filtered water or 0.00035 kWh per gal)
3. Minimal water losses (up to 98% water recovery) due to dead-end filtration
• High microbiological safety: stainless steel hygienic design and automatic disinfection when the system is out of operation for more than 24 hours
• Process traceability through performance monitoring and recording (data logger optional) and modules testing
• Simple, easy-to-operate, operator-friendly touch screen panel with pre-programmed sequences

Pall Aria FB Modules

Pall Aria FB modules are made up of Pall’s proven hollow fiber PVDF membranes. Due to the special homogenous structure of the hollow fibers, the modules distinguish themselves from conventional modules by requiring less cleaning and, at the same time, offering longer service life. Each module contains 50 square meters (538 square feet) of surface area.

The module components include
