“…The system resulted in an average removal efficiency of 70%, 70%, 34%, 52%, 45%, 74%, 21%, 43%, and 98% for COD, NH4-N, NO3-Multistage treatment wetlands can be used to remove nitrogen from high-strength wastewater (Wojciechowska et al, 2017 (West et al, 2017). Liu et al (2017) reviewed the potential of wetlands on advanced nutrient removal from surface waters by a consortium of attached microalgae and bacteria.

An update on the current research and development of wetland treatment technologies for wastewater treatment is provided in this paper. This article focuses on wetland applications in wastewater treatment (as an advanced treatment unit or a decentralized system), and nutrient and pollutant removal (metals, industrial and emerging pollutants including pharmaceutical compounds). A summary of studies involving the effects of vegetation, wetland design and operation, modeling, hybrid and innovative systems, landfill leachate treatment, and pathogen removal is also included.

Contrary to the constraints in time, investment, and management of the traditional technology for waste water treatment, this paper seeks to propose a more advanced, reliable, and affordable new technology to restore urban polluted rivers to pristine quality levels. The paper also presents new ideas on the selection and use of microbial agents to improve the efficiency of pollution removal. It presents the successful implementation of microbial technology (MT) on Chengnan River, which was heavily polluted before MT implementation. Without artificial aeration, sediment dredging, or complete sewage interception, we directly sprayed a previously configured HP-RPe-3 Microbial Agent into the water body and sediment. We considered the feasibility of MT for treating polluted urban rivers from the perspective of several water quality indices evaluation methods. After the treatment, the concentration of dissolved oxygen (DO) reached 5.0 mg/L, the removal rates of ammonia nitrogen (NH 3 -N) and chemical oxygen demand (COD) reached 20% and 38% respectively, and the average degradation rate of total phosphorus (TP) along river was close to 15%. Also, the Nemerow Index of the river was reduced from 2.7 to 1.9. The Fuzzy Comprehensive Index shows a tendency for improvement from Inferior Grade V to a better grade (approximately Grade III). The color of the river water changed, from black or dark green, to its original color. The results indicate that the bioremediation technology of directly adding microbial agents mainly aimed for the degradation of NH 3 -N can preliminarily eliminate the black-odor phenomenon of urban rivers, and improve their water quality. It is expected that the MT application, and the concept of how to select the corresponding microbial agents according to main pollutants, can be widely accepted and applied to similar cases.

“…This consortium between microalgae and bacteria has shown promising results for high strength and municipal wastewaters (Godos et al, 2010;González-Fernández et al, 2011a;Hernández et al, 2013;Su et al, 2012a;Liu et al, 2017;Maza-Márquez et al, 2017). They can achieve nitrogen removal efficiencies of between 50 and 90% without (external) aeration and phosphorous removal efficiencies of up to 60% mostly by entrapment in the biomass or chemical precipitation.…”

“…Microalgal-bacterial consortia can to successfully treat a wide range of wastewater effluents containing different concentrations of nutrients and organic matter, and using different operational conditions (Godos et al, 2010;González-Fernández et al, 2011a;Hernández et al, 2013;Su et al, 2012a;Liu et al, 2017;Maza-Márquez et al, 2017). The identified removal mechanisms are: nitrification/denitrification, algal uptake, nitrogen requirements for bacterial growth and depending on the pH, ammonium volatilization (Godos et al, 2009;González-Fernández et al, 2011a; Chapter 3; Chapter 4).…”

Also to a great group of friends Peter, Berend (yes Berend you are double), Mohaned, and Jeffrey thank you for being there, for always asking, for always remind me that I can, for your advices, your laughs, and even more thanks for all the moments we have shared, and we will continue sharing. To Nata and Fer you are such a extraordinary women, and I am lucky and proud to call you my friends, you both are one of a kind. I have learnt from each of you so much, you have never let me down, and you have became a rock while here in Delft. You are like sisters to me. Let's cheer for more adventures, anecdotes, talks, learning experiences and stories!. Las quiero muchoo!!. A mi Familia no hay palabras para expresar el amor, el agradecimiento y admiración que siento por ellos. Ellos son las personas más valiosas e importantes de mi vida: Mi papá,
