Ammonia Stripping Tower

This is a technology that separates ammonia from water through contact with air after changing ammonium ion in water into ammonia through pH control. This is the level that can treat high concentration ammonia biologically for wastewater that cannot be treated using the previous biological denitrification process. It is a technology that makes biological treatment done efficiently and stably by adjusting the C/N ratio to a suitable level by removing nitrogen in wastewater.

Principles

  • Ammonia Stripping Tank: It is installed to treat leachate generated in a landfill to the level satisfying the legal standard for water quality allowance at a connected treatment plant by water-treating NH3-N in water by blowing into the air using an ammonia stripping process.
  • Ammonia Stripping Tower: It transforms ammonia into a gas by circulating a lot of air to nitrogen in wastewater through an ammonia stripping fan.
  • Ammonia Stripping Tower (Absorption Tower): It transforms ammonia gas ingredients in wastewater to harmless, odorless ingredients through wet cleaning including an absorbent.

Purified gas is discharged as a harmless, odorless ingredient as gas and liquid are separated when the staying time of an aquatic plant passes. The purified liquid is discharged into a flux control tank and enables connected treatment to the next biological treatment process.

Features

  • Degasification and integrated system to remove ammonia and nitrogen
  • Strong against early ammonia load changes
  • High nitrogen removal efficiency
  • Advantageous to high pH
  • Low system investment expenses and easy to maintain
  • Not affected by the salinity of influent

Application

  • Leachate treatment system
  • Wastewater containing high concentration nitrogen
