Virginia Beach - Atlantic

Virginia Beach-Atlantic

The Atlantic Wastewater Treatment Plant is one several facilities owned and operated by the Hampton Roads Sanitation District (HRSD) in eastern Virginia and the Eastern Shore.

A Cambi thermal hydrolysis process unit was installed at the plant in 2020 to facilitate advanced anaerobic digestion. This will allow the utility to centralise sludge treatment at the site as it gradually decommissions its incinerators at other HRSD treatment plants.

The six drivers as to why HRSD decided to go with THP at the Atlantic Treatment Plant:

1. Significantly less storage capacity required at the plant
2. THP will provide Class A quality biosolids
3. The THP is nearly energy neutral
4. THP easily incorporates phosphorus release
5. The THP provides a good opportunity for dewatered biosolids receiving from other treatment plants
6. Having the higher digester loading capability increases current digester capacity [2-3 times]
