Membrane Makeover

Membrane processes can be classified in many ways, based on nature, structure or driving force. Hydrostatic pressure differences are used in microfiltration (MF), nanofiltration (NF), reverse osmosis (RO) and gas separation as the driving force for mass transport through the membrane.

RO Systems

Company Reference: 

AXEON X2 Industrial Reverse Osmosis Systems are engineered to produce high-quality water by reducing dissolved minerals, bacteria and organic impurities with product water outputs from 50,000 to 1,000,000 gpd. AXEON X2 systems represent an exceptional offering for customers who seek an efficient water treatment solution for drinking water, cooling towers, boiler feed, food processing, bottling, agriculture and a variety of other applications.

RO System

Company Reference: 

Powered only by the hydraulic energy of brine water that is usually lost to the drain, the Permeate Pump—which can be included with Nelsen’s Aqua Elite RO system—forces product water into the storage tank, reducing membrane back pressure and maximizing available feed pressure. These pumps dramatically improve the efficiency of RO water production, reducing wastewater by up to 80%. They can also bring storage tanks up to line pressure and then shut the system down when the tanks reach capacity, eliminating the need for a hydraulic shut-off valve.

New Year, New Initiatives

The Water Quality Assn.’s (WQA) Gold Seal product certification program continues to grow and expand to meet the needs of the industry. This is being accomplished while maintaining quality control procedures and customer service. Regulatory acceptance of Gold Seal certification has reached a new high with the addition of the U.S. Environmental Protection Agency’s (EPA) Energy Star program, which is now accepting the Gold Seal program for compliance of water coolers.
