Restoring biological treatment performance after a toxic discharge, a pH excursion or an organic shock load..
How to calculate a bacterial culture dose, how often to repeat it, and which measurements tell you whether it is having an effect rather than whether it was delivered.
Why nitrifying bacteria recover slowly in cold water, what the practical consequences are for a plant, and which interventions help and which waste time.
Black odour in rivers, channels and receiving waters comes from organic load and low oxygen. What biological treatment can do, what it cannot do, and how to tell a treatable cause from a source that must be stopped.
What a shock load does to the sludge, what to dose and when, and realistic recovery timelines for a plant that has lost its biological activity.
