MBBR Technology is Supplied for Ammonia Removal to City of Palmer, Alaska 

Veolia Water Technologies, through its business unit Kruger, was awarded a contract from the City of Palmer, AK, to supply an AnoxKaldnes™ Moving Bed Biofilm Reactor (MBBR) for its Wastewater Treatment Facility (WWTF). 

The City of Palmer WWTF has chosen Veolia’s MBBR system to provide ammonia removal capabilities to ensure the cleanest effluent possible is discharged into the northernmost channel of the Matanuska River. The MBBR is a very effective nitrification solution that is easy to operate and control, and is a high performance technology as a cold weather application. Veolia’s design built in expandability so the plant can increase future capacity as needed with ease and cost efficiency. Veolia was selected for this contract for its extensive experience and expertise with MBBR installations across the country. 

AnoxKaldnes Moving Bed Biofilm Reactor (MBBR) is a biological wastewater treatment process that utilizes specialized polyethylene carriers (media) to create a large protected surface on which beneficial microorganisms attach to form a biofilm for treatment. The media is aerated and mixed in the reactor using a stainless steel air diffuser system. 

The AnoxKaldnes MBBR installation, expected to be fully operational in the summer of 2018, will give the Palmer WWTF a compact, yet robust treatment process capable of decreasing the ammonia nitrogen concentration to < 1.0 mg/L through nitrification. The AnoxKaldnes MBBR was chosen because it’s a robust and cost-effective biological
