AquaR2RO is an enhanced reverse osmosis process that integrates a unique membrane configuration to cost-effectively treat difficult waters. The AquaR2RO (R2=Robust and Reliable) process renders ultra-high recovery (99%) in treating high TDS water due to its ability to withstand higher than normal operating pressures. High recoveries across the membranes reduce the sizing of the thermal equipment, which constitutes the major part of the CAPEX and OPEX of the recycle system.
AquaR2RO can handle high TDS preconditioned waters with contaminants like organics, COD, and oil and grease as it operates at high cross flow velocities and a low per pass recovery. The salts rejected at the surface of the membranes do not cause any precipitation or concentration polarization effect. They immediately diffuse into bulk solution, and the concentration happens gradually.
