<p>A method of alkalinity control in biological wastewater treatment comprising at least one alkalinity shifting biological step (2) and at least one alkalinity correction step (8). The alkalinity control is provided by a combination of a recuperable abiotic species that forms soluble bicabornates and insoluble carbonates or hydroxides and by conditioning sludge in a step (7) to increase methanogens and recycling the conditioned sludge to the reactor.</p> |
