Oldcastle Precast Clarifiers Part of Algaewheel Project

Oldcastle Precast, a precast and polymer concrete manufacturer, has supplied precast concrete clarifiers to Algaewheel Technologies for a nutrient removal system at the Hopewell, Va., municipal wastewater treatment facility.

Steve Kingsland of Oldcastle Precast said, “We are extremely pleased to be part of this ground-breaking project being built by Thieneman Construction and Algaewheel Technologies. Algaewheel’s algae-based wastewater technology being used for the facility is also the central component in our green line of Maxpac™ packaged wastewater treatment plants and Bacpac® onsite systems. Solar energy is used to convert nutrients in the waste stream directly to valuable algae biomass, while consuming CO2,” Kingsland added.

The Algaewheel system is part of a 100,000 gallons per day, bolt-on nutrient removal pilot system for the Hopewell municipal facility that discharges to the Chesapeake Bay watershed. Algae biomass created from the process will be used for biofuel production, cogeneration, or fertilizer. The Hopewell facility started operation in December 2009.
