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

Primarily designed for nitrate removal, with the addition of metal salts the DynaSand® Deni can also provide removals of effluent phosphorus down to 0.2 mg/l and effluent BOD and TSS down to 10 mg.

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** - (upgrade option to include metal salts dosing)
  • Effluent Nitrogen removal - Down to 10 mg/l Total N
  • 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.

A carbon source such as methanol is added to the wastewater stream prior to the filter. This encourages the growth of heterophic denitrifying bacteria within the filter media bed.
