Recycle wastewater to meet environmental quality standards, and use it for irrigation, recharging watersheds and aquifers, and industrial processes.

The amount of wastewater produced by municipalities and industry is substantial and, if left untreated, poses a significant threat to aquifers, rivers, lakes, and watersheds. Recycled wastewater and secondary effluent, on the other hand, are potential resources. These resources are especially needed where water is scarce from drought or high population density.

When you use the Pall Aria™ system to process wastewater and secondary effluent, the product is of such integrity that you can safely use it for agriculture and industry. This enables you to conserve the scarce fresh water for drinking or to reduce purchases from the municipal drinking water supply.

Secondary effluent
Secondary effluent recycling utilizes microfiltration with or without downstream reverse osmosis treatment. When a Pall Aria system is used, the effluent meets the US EPA’s National Pollutant Discharge Elimination System requirements for reducing Cryptosporidium and Giardia. Based on this criterion, the high-quality discharge can be used for irrigation, aquifer injection, recharging of watersheds, and industrial processes. In addition, secondary effluent can be treated for use as boiler feed water and cooling tower water.

Membrane-coupled bioprocess
In recent years, membranes have been used in conjunction with biological treatment, without a secondary clarification step. The Aqua MB Process couples Pall Corporation’s membrane technology with the biological treatment expertise of Aqua Aerobic Systems Inc. to deliver a cost-effective alternative to membrane bioreactor systems.

The Pall Aria system is ideally suited to this application since it is pressure-driven and uses membranes that are extremely robust and chemically-resistant. If you’re installing a new wastewater treatment facility, it will be more efficient and have a smaller footprint, higher-quality effluent, and greater throughput. If you have an existing facility, you’ll benefit from greater throughput without altering the current footprint of the plant.
