Tertiary Phosphorus Removal


Removal of phosphorus in a tertiary process is required in many cases to meet low level phosphorus effluent requirements. Tertiary filtration removes particulate associated phosphorus. Chemical may also be added in a tertiary step to precipitate soluble phosphorus to improve the removal of total phosphorus. Aqua-Aerobic Systems specializes in tertiary phosphorus removal through our cloth media filtration and membrane system technologies.


Advantages of Tertiary Phosphorus Removal with Cloth Media Filtration

  • OptiFiber® pile cloth filtration media is custom designed for tertiary wastewater treatment applications to maximize particle removal and provide 7-10 year media life
  • OptiFiber PES-14® cloth filtration media is the most common choice for low level phosphorus limits less than 0.075 mg/L
  • As permit limits change over the life of the plant, the filter media can be easily changed to meet the new limits without changing mechanical equipment in the filter
  • Cloth media filters are easily retrofitted into existing filter basins and other structures to make plant improvements for new permit requirements seamless
  • Over 100 cloth media filter installations for low total phosphorus
  • Bench-scale and pilot testing services to demonstrate performance as part of the design process

Advantages of Tertiary Phosphorus Removal with Membranes

  • Incorporates phosphorus into the sludge for ease of removal via WAS or Filtration
  • Chemical addition savings
  • Reduction of sludge production compared to chemical addition

Tertiary Phosphorus Removal

Membranes


Phosphorus comprises approximately 1-5% of the suspended Solids in a biological system. The more solids that are removed, the more phosphorus is removed. Uniform pores at sub-micron levels, provides the best solids removal available and with it, great removal of phosphorus associated with those solids.

Application of progressive staged filtration following the biological system

Read White Paper

An alternative to the membrane bioreactor is the application of progressive staged filtration following the biological system. This Multi-Barrier Treatment Process (MBTP) is an innovative solution that integrates the sequencing batch reactor (SBR) process and cloth media filtration (CMF) to produce an exceptionally high quality membrane-feed, with solids less than 5 mg/l.
