Technology Strengths, Weaknesses and Critical Indicators
Centrifuge Technologies remove the non-dissolved particles from the waste stream typically resulting in a lower solid liquid that will not plug equipment or irrigation quality “tea water” depending on whether the technology is used with or without polymer:
- Produces a stackable solid which is high in phosphorus and with significant amounts of organic nitrogen.
- There is significant variation of energy use depending on the site and by technology
- There is significant variation of operational intensity depending on site, use of polymer, and by technology
- There is significant variation of cost depending on site, use of polymer, and by technology
- Can be used with or without polymer. Recovery rates and impact on critical indicators are better when used with polymer.
- Proven technology for nitrogen recovery, phosphorous recovery, storage reduction, GHG reduction, and odor control
Suspended solids/phosphorus recovery technologies:
- Produces a concentrated source of phosphorus from a renewable source
- Include belt presses, centrifuges, dissolved air flotation systems and others
- There is significant variation of chemical and energy use by site and by technology
- There is significant variation of operational intensity by site and by technology
- There is significant variation of cost by site and by technology
