An energy-efficient wastewater treatment system based on the combination of Cambi THP and mainstream deammonification

Recovering energy from wastewater represents an ongoing paradigm shift from energy-negative to energy-positive. Here are two directions to drive the shift. On one hand, maximize energy production; on the other hand, minimize energy consumption.

Maximizing energy production can be done through carbon redirection and capture technologies coupled with anaerobic digestion (AD). On an industrial scale, thermal hydrolysis pre-treatment (THP) is the most profitable and reliable technology to enhance AD process and Cambi is the most commonly used THP technology. But the liquor after Cambi-AD process is tricky to handle with. Deammonification is an energy-efficient nitrogen removal process to minimise energy consumption. It consists of partial nitritation and ANAMMOX. But the implementations of deammonification in mainstream are still in infancy, with suppressing NOB being the biggest stumbling block in the way.

Based on the hypothesis that some inhibitory matter in Cambi-AD liquor could selectively suppress NOB, an energy-efficient wastewater treatment system combining Cambi and deammonification will be explored in this PhD project.
