Groundwater Remediation Project | Barstow, CA
From Contaminated Groundwater to Potable Water
Due to the presence of serious contaminants and potentially hazardous material in groundwater, there is an increasing threat to human health. Regions like the West and the Midwest with high concentrations of livestocks has already suffered from groundwater contamination. Facilities that use groundwater as tap water recognized the potential dangers of contaminants and has begun to put up warning signs to the public.
As water becomes an increasingly scarce resource worldwide, both financial and environmental concerns have prompted escalating demand for groundwater remediation. Fortunately, BBF's highly effective biofiltration process can remediate contaminants such as nitrate, perchlorate, and organics to meet Federal Maximum Contamination Level (MCL).
BBF Bio-filtration for Nitrate & Perchlorate
Under BBF’s anoxic conditions, indigenous microorganisms colonize in the bioreactor and consume nitrate and perchlorate, converting them into nitrogen gas and salt. BBF process meets the Federal MCL drinking water regulations while saving energy. Using gravity to naturally backwash the media bed, BBF system eliminates the need for pumping or mixing.
The purpose of this project is deployment of two full-scale Biofiltration vessels (BBF) for the treatment of groundwater contaminated with nitrate and to confirm the water quality and energy savings. In addition the data will be used to attain California Title 22 water quality standards.
Meeting these standards will secure potable water supply for local residents in the long run. This project will offer demonstration and optimization of BBF filtration system for treatment of approximately 0.25-0.5 MGD contaminated groundwater. The lower flowrate has been defined to achieve simultaneous treatment of nitrate and perchlorate in the event that the perchlorate migrates to the proposed project site.
No Brine: BBF converts nitrate into N2 gas and perchlorate into salt, removing the abatement cost
Low Operational Cost: No need to transport byproducts to a waste facility
Energy Saving: Uses gravity to naturally backwash the media bed, no need for pumping or mixing
