AG High Rejection Brackish Water Commercial Elements are selected when high solute rejection is required and an operating pressure up to 200 psig is acceptable. These elements are considered a standard in the industry. AK Low Pressure Brackish Water Commercial Elements are selected when the highest solute rejection is not needed but a low operating pressure is desired. These elements allow significant energy savings since good rejection is achieved at operating pressures as low as 100 psig.These elements are designed for light industrial or commercial applications. For cost optimization, they feature a tape outer wrap.

• SDI is measured on a non-linear scale using a 0.45 micron filter paper. Addition-ally, finer colloids, particulates and microorganisms that pass through the filter paper and not measured in the SDI test, will potentially foul the RO element.
