IDE Technologies' technology is being used in two new wastewater reuse demo facilities in California: the Central Coast Blue Advanced Water Purification Demo Facility, in partnership with the City of Pismo Beach, and the Regional Recycled Water Advanced Purification Center Demo Facility, in partnership with the Metropolitan Water District of Southern California and the Sanitation Districts of Los Angeles County.
As California has been severely impacted by drought and the state continues to face a shortage of groundwater, advanced water reuse is proving to be a sustainable alternative for a clean, efficient and safe water source for groundwater replenishment in the state.
For the Central Coast Blue facility located in the City of Pismo Beach, IDE will demonstrate an energy-efficient solution with reduced chemical consumption to produce purified water. The facility will have a capacity of 58,000 gallons of water per day and will allow IDE to demonstrate and test its proprietary recycled water process, Ecological Reuse (Eco-Reuse).
The Eco-Reuse process is designed to optimize performance while minimizing costs. It uses a proprietary preventative maintenance approach without the use of chloramine and hence avoiding the formation of N-nitrosodimethylamine (NDMA), an organic contaminant suspected as carcinogenic.
IDE will demonstrate its reverse osmosis (RO) process for wastewater reuse in the Regional Recycled Water Advanced Purification Center Demo Facility located in Carson. Wastewater discharged from homes, businesses and industries will be cleaned and treated and then sent to the water treatment plant for further purification. The facility will have a capacity of 500,000 gallons of water per day.
IDE’s RO will be integrated into a novel process using membrane bioreactors (MBR) as a pretreatment to the RO to remove tiny particles, biodegradable pollutants and nitrogen compounds. The RO system will then be used to remove suspended and dissolved components, such as bacteria, viruses, pharmaceuticals and salts, eliminating more than 99% of all impurities. Once the water completes the full purification process, it will be used to replenish Southern California’s groundwater basins.
The Prismo Beach facility opened to the public on 15 May. The Carson facility will open in late 2018.
