Desalitech pilots wastewater treatment system in Los Angeles

The Desalitech Closed Circuit Desalination (CCD) system will help the Sanitation Districts to lower chloride levels in the Santa Clarita Valley’s treated wastewater to below the limits set by the State, avoiding fines while increasing efficiency and reducing salts and other impurities. High recovery will effectively reduce effluent discharge and brine disposal costs, which can represent over 50% of total water treatment project costs.

The pilot study will be completed at the Whittier Narrows WRP to model data for the Valencia facility 100 miles north of Los Angeles. The Desalitech system will process 15 gallons per minute of municipal wastewater effluent as part of the Sanitation Districts’ research efforts to evaluate technologies to reduce chlorides in discharges from treatment plants in the Santa Clarita Valley. The pilot study will be conducted for 2000 hours at recoveries ranging from 85% to 93%, while monitoring average specific energy, permeate quality, and scaling potential.

Successful testing at the Sanitation Districts could lead to implementation of a full-scale system at the Valencia Water Reclamation Plant (WRP) which produces 22 million gallons of municipal effluent per day.
