  4. Enhancing Mixing and Aeration: Proper mixing and aeration helps even distribution of microorganisms, leading to better nitrification. Active mixing systems and air diffusion devices can help.

MBRs provide a good solution for Ammonia From Wastewater treatment facilities looking for effective ammonia removal methods. Anion exchange resins are also a great sidekick for removing this smelly offender from wastewater.

Anion exchange resins

Anion exchange resins can be used for efficiently removing ammonia from wastewater. They trade negatively charged ions with the ammonia ions, thus eliminating them. Here’s how they do it:

A resin bed is formed with the resins, which acts like a filter. They have a strong attraction to ammonia ions, and grab onto them.

The wastewater passes through the bed, and the ammonia ions get drawn to the negatively charged resin beads, such as chloride or sulfate ions.

The exchanged ammonia ions stay bound to the beads, thus removing them from the water. The treated water exits the bed, now free of a majority of its ammonia.

But, eventually the resin gets saturated with ammonia ions and needs to be regenerated. This is done by passing a regeneration solution, like brine or caustic soda, through the bed. The solution forces the bound ammonia ions away from the beads, so they can be reused for more treatment.

Tip: To ensure optimal removal of ammonia, regularly check the resin performance and regeneration intervals. Removing ammonia may be a challenge, but it sure beats taking glitter out of your clothes after a wild night!
