Abstract Wastewater treatment plants are the major energy consumers and significant sources of greenhouse gas emissions, among which biological nitrogen removal wastewater is an important contributor to carbon emissions. However, traditional heterotrophic denitrification still has problems excessive residual sludge requirement external sources. Consequently, development innovative low-carbon nitrate technologies necessary. This review outlines key roles sulfur autotrophic hydrogen in treatment. The discovered nitrate/nitrite dependent anaerobic methane oxidation enables sustainable emission reduction by utilizing available situ . Photosynthetic microorganisms exhibited a promising potential achieve carbon-negative removal. Specifically, algal-bacterial symbiosis system photogranules offer effective prospective options for Then, emerging technology photoelectrotrophic underlying photoelectron transfer mechanisms discussed. Finally, we summarize prospect these technologies, highlighting that solar-driven area future guiding significance design systems.

Nitrogen mitigation is serious environmental issue around the globe. Several methods for wastewater treatment have been introduced, but biological denitrification has recommended, particularly with addition of best external carbon source. The key sites are wetlands; it can be carried out different methods. To highlight aforementioned technology, this paper deals to review literature evaluate and demonstrate cost effective sources. results systematic disclose process online exploration was accomplished using most well-known databases, that is, science direct web database, resulting 625 articles 3084 research articles, published in peer-reviewed journals between 2015 2021 were identified first process. After doing an in-depth survey exclusion criteria, we started shape from selected articles. A number studies confirmed both nitrification significant wastewater. proved source main contributor a booster denitrification. Based on reviewed concluded option nitrogen changing world. Our study recommends textile waste recovery
