Microvi MNE Outperforms Established Tertiary Ammonia Removal Process at Thames Water Wastewater Treatment Plant
Thames Water Utilities Ltd. and Microvi Biotechnologies completed a collaborative 9-month trial demonstrating Microvi's novel wastewater treatment, Microvi MNE™ (MNE). The fully automated MNE demonstration plant was configured as a tertiary nitrification system for ammonia removal. Operating between 5-22 degrees Celsius, MNE consistently removed ammonia from wastewater during continuous operation outperforming the ammonia removal rates of the existing nitrifying sand filters. MNE showed resi...
Rice Engineers: Make Wastewater Drinkable Again
A schematic representation of the hybrid water supply system developed by engineers at Rice University. The researchers suggest that delivering water to city dwellers can become far more efficient, and that it should involve a healthy level of recycled wastewater. (Credit: Lu Liu/Rice University) Model shows recycling could dramatically slash cities’ need for fresh water resources HOUSTON – Delivering water to city dwellers can become far more efficient, according to Rice University r...
