A review on nitrogen and organics removal mechanisms in subsurface flow constructed wetlands: dependency on environmental parameters, operating conditions and supporting media.
Tanveer Saeed,Guangzhi Sun +1 more
TL;DR: A comprehensive review of wetland structures, classic and novel nitrogen and organics removal mechanisms along with the key environmental parameters and operational conditions that enhance removal in subsurface flow wetland systems shows the necessity of a profound knowledge on the complicated inter-relationship between nitrogen and Organics removal routes, governing environmental and operational parameters, and wetland matrix for improving the treatment performances of subsurfaced flow wetlands.

Biological nitrate removal from water and wastewater by solid-phase denitrification process.
Jianlong Wang,Libing Chu +1 more
TL;DR: More attention should be paid to the simultaneous removal of nitrate and toxic organic contaminants such as pesticide and PPCPs by solid-phase denitrification, to the elucidation of the metabolic and regulatory relationship between decomposition of solid carbon source and denitification, and to the post-treatment of the municipal secondary effluent.

Long-term effect of dissolved oxygen on partial nitrification performance and microbial community structure.
TL;DR: Comparing the performance of partial nitrification via nitrite and microbial community structure were investigated and compared in two sequencing batch reactors with different dissolved oxygen (DO) levels indicated that selecting properly DO level and adopting process control method is not only of benefit to the achievement of novel biological nitrogen removal technology, but also favorable to sludge population optimization.

Nitrification-denitrification via nitrite accumulation for nitrogen removal from wastewaters
TL;DR: The biological nitrification-denitrification process is used extensively for removal of ammonia nitrogen from wastewaters and saves in aeration, organic matter (for denitrification) and surplus sludge are achievable if nitrite accumulation is possible in the nitrification step.

Inhibition of nitrification by ammonia and nitrous acid
TL;DR: The importance of NITRIFICATION has been recognized for more than a hundred years and engineers and scientists continue to investigate the process to obtain a better understanding of the fundamentals and to use the process for the benefit of man.
Journal Article
Inhibition of nitrification by ammonia and nitrous acid.
TL;DR: Control nitrification may occur during waste treatment, and engineers have begun to incorporate the process as part of nitri fication-denitrification systems for nitrogen control preceding discharge of the treated wastes.
