IDE Wastewater Reuse Demo Facilities a Crucial Step in California: Gilad Cohen, CEO, IDE Americas


IDE Technologies has announced that its technology will be 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.

Wastewater Reuse Demo in California

For the Central Coast Blue Advanced Water Purification Demo 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. It will allow IDE to demonstrate and test its proprietary recycled water process, Ecological Reuse (Eco-Reuse).

The company will demonstrate its reverse osmosis (RO) process for wastewater reuse in the Regional Recycled Water Advanced Purification Center Demo Facility located in Carson. Once wastewater is discharged from homes, businesses, and industries, it will be cleaned and treated then sent to the advanced water treatment plant for further purification. The facility will have a capacity of 500,000 gallons of water per day.

Mayur Sharma discussed the concept and technologies behind the wastewater reuse demo facilities with Gilad Cohen, CEO of IDE Americas.

What is the idea behind setting up the demo facilities?
Gilad Cohen: IDE Technologies has developed new processes s to treat wastewater into potable water quality for direct/indirect use. The offered processes are more environmentally-friendly and efficient compared to the existing market standard. The demo facilities will assist IDE to validate these processes in local California facilities and it will also enable access to the regulators, the public, clients and consultants to have a firsthand evaluation of the technologies. The demo facilities also support the overall efforts of the local communities of Pismo Beach and Carson to identify the ideal treatment approaches to create a reliable, sustainable and affordable water supply for municipal use with IDE’s advanced technologies. The demo facilities will optimize performance and are a crucial step in California realizing the immense benefits of potable wastewater reuse.

Looking at the current drought-like situation in California and many world cities, how can such facilities reinvigorate the groundwater supplies?
Gilad Cohen: By reusing wastewater, water is being recycled, as opposed to tapping into natural water sources. After wastewater is cleaned and treated through multiple processes, it flows to the Regional Recycled Water Advanced Purification Center Demo Facility for further treatment and purification. The end result is high quality, purified water that could eventually help replenish groundwater. With the large-scale implementation of recycled water facilities, the need to utilize already depleting water supplies is lowered. California and other cities around the world can benefit from a safe, reliable and affordable source of clean, drinkable water in the face of drought-like conditions.

Tell us more about Eco-Reuse.
Gilad Cohen: The standard water reuse process, known as Fully Advanced Treatments (FAT), includes a dosage of chloramine. Chloramine is a precursor of N-Nitrosodimethylamine (NDMA) formation – an organic contaminant suspected as carcinogenic. Ecological Reuse (Eco-Reuse) operates without the use of chloramine dosage. Instead, it uses Direct Osmosis High Salinity (DOHS) and conservation which helps to control biofouling. These mechanisms ensure that Cleaning in Place (CIP) is a longer process, which lowers energy consumption and reduces overall associated environmental impacts. This process is safer than the industry standard as there is no chloramine usage and more economical as the overall energy usage in the process is lower.

Do you think that a large-scale implementation of these technologies will be possible soon?
Gilad Cohen: Within three months, and as soon as there is enough data collected to demonstrate the reliability of the process, our wastewater reuse technologies can be used for large-scale implementation.
