What carbon source does Blue Nite use?

Blue Nite is flexible and can use many of the most common carbon sources, including methanol, acetic acid, ethanol, glycerin, as well as proprietary products like MicroC®.

What carbon dosing ratio does Blue Nite use?

Optimal carbon dosing depends strongly on water characteristics such as DO as well as the BOD strength of the carbon source. Nexom’s chemical engineers can help you determine the ideal ratio at your site to achieve the required denitrification level.

Can our Blue Nite installation be retrofitted at a later time for Blue PRO reactive filtration if we don’t need phosphorus removal yet?

Definitely, and we have helped other customers do this before. In fact, the amount of “retrofitting” required is minimal. Because the two systems utilize the same Centra-flo® granular media filtration system as a process platform, the additional infrastructure required is the Blue PRO’s dosing system and virtually nothing else. (The same goes for Blue PRO installations being retrofitted for Blue Nite biological denitrification.)

Can the system be installed into pre-existing tanks?

In some cases, the Blue Nite technology can be retrofitted to existing tanks. Contact our project development team to learn how your specific tanks could be integrated with the Blue Nite process.

does the media need to be replaced or topped up?

Many older sand filter design of 20 years ago were prone to occasional media loss. Our washbox design coupled with our unique control and monitoring systems mitigates this concern. A Blue Nite system will waste almost no media in its lifetime, meaning that in a 20-year period, topping up is unlikely to be required, and the media should never need to be replaced.
