With an average rejection rate of 99.2%, the SPECTRUM PRO range of membranes is engineered to deliver permeate flow rates at the lowest operating pressure in the SPECTRUM membrane range, starting from just 5.5 bar. This exceptional performance makes it perfectly suited for tap water applications with feed water typically at 500 mg/l or less. The PRO membrane achieves the optimum balance of performance at 6.9 bar and can be utilised to boost system production without the need for system alterations, ensuring efficiency and reliability in your water treatment process.
