NewTech Biochar Water Treatment
NewTech™ Biochar Water Treatment
Biochar-catalytic oxidation-reactive filtration wastewater treatment process
Pre-Commercialinstallations at water treatment operations from <1 mgd to >10 mgd (proven technology, not yet widely adopted)
On-site wastewater treatment and nutrient recovery for agricultural application
- Builds drought resilience:
- Enables process water to be reused, significantly reducing withdrawals of valuable potable water supplies (urban drinking water resources, including surface and groundwater).1
- Removes nitrates, phosphorus and other contaminants from process water effluent, enabling reuse for irrigation, groundwater recharge, drinking water for livestock, washing food processing equipment, and other non-potable purposes2
- Potential for treating water to high enough quality for direct potable reuse
- Addition of biochar to soils decreases bulk density, increases total pore volume, and increases available water content in a wide variety of sandy soils, which are common in Tulare County.1
- Biochar increases the drought resistance of fungal and bacterial communities within soil due to faster recovery from disturbances.2
- Supports electric reliability:
- Reduces electric consumption
- Reduces electric demand (kW)3
- Increases renewable energy production
- Reduces greenhouse gas emissions:
- Carbon-negative process uses modified biochar to remove contaminants and enhances the biochar for agricultural application, where it stores carbon for at least 200 years.
- Efficient capture and treatment of biosolids at the source reduces escaped methane emissions.
- Biochar Reduces CO2, CH4, and N2O flux of the soil, reducing agricultural greenhouse gas emissions.4
- Reduces ratepayer costs:
- Low CAPEX and OPEX
- Reduces regulatory and environmental risks:
- Nutrient removal and recovery reduce nitrate and phosphorous loads in effluent water, reducing nitrate contamination in groundwater supplies from reclamation areas.
