DynaSand Oxy is a continuous sand filtration system which uses the addition of air to facilitate the removal of ammonia from wastewater. This has the advantage of a single stage for ammonia, suspended solids and BOD removal. It can be used as a stand-alone addition to an existing treatment works.

Primarily designed for ammonia removal, for which it delivers removals down to 2 mg/l, the DynaSand® Oxy can also provide removals of effluent phosphorus down to 0.2 mg/l as well as effluent BOD and TSS down to 10 mg/l.


Applications

  • Wastewater treatment works
  • Industrial effluent treatment

Performance

  • Effluent TSS removal - Down to 10 mg/l*
  • Effluent BOD removal - Down to 10 mg/l*
  • Effluent Phosphorus removal - Down to 0.2 mg/l** (with upgrade option to include metal salts dosing)
  • Effluent Ammonia removal - Down to 2 mg/l*
  • Maximum flow rate per filter - 29 l/s

* effluent standards quoted to 95%ile

** annual average

The principle of operation is as the DynaSand® filter with continuous operation, water purification and media washing taking place continuously, enabling the filter to remain in service without interruption. This also negates the need for backwash water tanks or pumps. 


To ensure that the autotrophic nitrifying bacteria have sufficient oxygen and carbon dioxide to convert ammonia to nitrates, aeration hoods fed by process air are sited within the upper layer of media to provide sufficient aeration. The resultant nitrates remain dissolved in the water.
