Abstract Nitrate (NO 3−) pollution in water and wastewater has become a serious global
issue. Biological denitrification, which reduces NO 3− to N 2 (nitrogen gas) by denitrifying …

Autotrophic denitrification (AuDen) is an efficient, convenient and eco-friendly biological
process for the treatment of nitrate-contaminated organic-deficient waters. AuDen can be …

Nitrogen removal through microorganisms is the most important pathway in constructed
wetlands (CWs). In this review, we summarize the microbial coupling mechanisms of …

This article summarizes several developed and industrial technologies for nitrate removal
from drinking water, including physicochemical and biological techniques, with a focus on …

Many wastewater treatment plants in the world do not remove reactive nitrogen from
wastewater prior to release into the environment. Excess reactive nitrogen not only has a …

Several approaches of hydrogenotrophic denitrification of potable water as well as technical
data and mathematical models that were developed for the process are reviewed. Most of …

Chemolithotrophic denitrification is an inexpensive and advantageous process for nitrate
removal and represents a promising alternative to classical denitrification with organics …

The use of constructed wetlands for wastewater treatment is rapidly increasing worldwide
due to their advantages of low operating and maintenance costs. Denitrification in …

Biological denitrification was reviewed regarding its potential application to treating nitrate in
industrial wastewater. Although heterotrophic denitrification is an efficient and well …

Rapid dechlorination and full mineralization of para-chlorophenol (4-CP), a toxic
contaminant, are unfulfilled goals in water treatment. Means to achieve both goals stem from …
