High Production, Lower Pressure

With an average rejection rate of 99%, the ERO range of membranes has been designed to deliver higher permeate flow rates in lower pressure applications. Delivering exceptional performance at pressure as low as 6.9 bar, perfectly suited to tap water applications with a feed water concentration typically of 500 mg/l or less. Whilst an optimum balance of performance is achieved at 10.3 bar.
