This powerpoint presentation begins by providing background information on the City of Rio Rancho, the4th largest city and the fastest growing city in New Mexico. ItsWater Reuse Strategy consists of:expanding the use of reclaimed water; and, reducing groundwater withdrawals.Integrated Membrane System (IMS)includes;IMS integrates two or more membranes with other processes;IMS can be used to achieve multiple treatment objectives;IMS is increasingly being considered for wastewater recycling;IMS system generally includes Reverse Osmosis (RO) process; and,RO generates a significant volume of concentrated waste. Research objectives include:investigate innovative beneficial reusealternatives of RO-concentrate; and, investigate several innovative ideas tominimize RO-concentrate volume. A schematic of the IMS Pilot Process is presented, along with the MBR Pilot System; the RO pilot system; points on Concentrate Beneficial Reuse; bipolar membrane electrodialysis; experimental setup; results: acid and base production; cost evaluations assumptions; economic feasibility: BMED; concentrate minimization; forward osmosis; osmotic pressure measurements; evaluation of draw solutions; selected draw solutions; innovative draw solution; evaluation of membranes; dewatering RO concentrate using FO; results: decline in specific flux, and effect of chemical cleaning.
