AXEON Double Pass High Purity Water Reverse Osmosis Systems
AXEON Double Pass Reverse Osmosis (DPRO) Systems are commonly selected when there is a specific need or desired water quality required within an application. This can be achieved by using two entirely different RO systems or configuring the 4-inch or 8-inch RO membranes in a two pass configuration on a single skid. This allows for the RO concentrate or reject water to be fed into a second RO system or bank of membranes and to recover water, thus producing a typical salt rejection level of >99%.
AXEON RDP and MDP-Series Double Pass Ultrapure Reverse Osmosis Systems are designed for a variety of industrial applications requiring high quality equipment with fast delivery and competitive prices. These pre-engineered, assembled and factory tested systems feature easy-to-set controls that minimize installation and start-up times and allow for quick online service. AXEON DPRO Systems serve process water generation industries that need ultrapure water, such as Power Generation, General Industry, Food and Beverage, Cosmetics, Pharmaceutical and Microelectronics.
Why are Double Pass RO Systems Beneficial?
Climate change has caused many parts of the world to experience droughts, so there is always concern about conserving water and maximizing a system's recovery (water efficiency) of waste water. Traditional single pass RO systems achieve approximately 75% efficiency, while double pass RO can achieve an efficiency of 90% or more. In addition, this method of designing a reverse osmosis system can also be beneficial for the production of high purity permeate water for high purity and ultrapure water applications. Other water treatment technologies such as electrodeionization (EDI) or mixed bed deionization (MBDI) may be utilized in order to obtain similar water quality levels.
