Struvia is a solution for recovery of phosphorus from effluents produced by various industrial and agricultural activities, or from municipal waste facilities, as struvite crystals. This opens the way to a local reuse of phosphorus especially in agriculture.

The recovery and recycling of phosphorus is important due to declining rock reserves along with environmental issues. Recovery would limit the release of phosphorus into the natural habitat, which causes eutrophication

Benefits

  • Reduction in sludge production in wastewater
  • Reduced operating costs
  • Limited space requirements
  • Reduced maintenance costs

Operating principle

Effluent containing high concentrations of phosphorus, for example centrates generated from digested sludge dewatering, are fed to a continuous stirred tank reactor where rapid mixing is achieved using a special mixing system: Turbomix™. Struvite precipitation is initiated by increasing the pH and by addition of a magnesium salt.

An integrated lamella settler ensures the separation of the produced struvite prills and the treated effluent. Typically in municipal applications the treated effluent is returned to the head of the treatment works.

For industrial applications Struvia is applied on the waterline. The effluent can be discharged directly or further treated if required.

The struvite prills are then pumped and directed to a draining and storage facility before they are sent to the packaging unit.

Turbomix encourages crystallization and growth of struvite pellets and it allows for optimum use of reactive products with a short reaction time, hence limiting space requirement.

Applications

  • Wastewater treatment plants
  • Household waste methanisation projects
  • Territorial methanisation sites
  • Livestock effluents in agriculture
  • Food and Beverage industry
  • Agrichemcial industry
