Reseeding Nitrification/Denitrification Oxidation ditch
We have lost nitrification in our oxidation ditches. We are looking to reseed with local WAS from another plant. Any tips regarding quantity of WAS to import or process control settings while adding new bugs. Thanks.
Shannon, Stop wasting. Where do you normally wast to? If aerobic digester then use this as your seed. Why did you loose nitrification? Quantity of seed would depend on volume of ditch. I would suggest 20% of ditch volume to start with.
