Analysis of hydrochemical time series
(Corresponding) Kolarec B., Žeravica A.
Topic:
Soil and groundwater contamination and remediation
Agricultural activity of spreading fertilizers may, in case they are washed away to an aquifer, result in a groundwater contamination. There was a research conducted in Croatia on the lower part of the Danube-Sava canal which is occupied by extensive agricultural production to measure the...Read more

High-rate anaerobic co-digestion of agro-industrial wastes combined with ammonia recovery and biogas purification
Eftaxias A., Georgiou D., (Corresponding) Diamantis V., Koumara A., Koskinari M., Aivasidis A.
Topic:
Environmental biotechnology and bioenergy
Screened dairy manure, pressure-sterilized animal by-products, and cheese whey were co-digested in a Plug Flow Reactor (PFR) over a period of 150 days. The mixture was characterized by TCOD = 70±8 g/L, SCOD = 26±6 g/L, NH4-N = 1.5±0.3 g/L, TSS = 20±5 g/L, VSS = 18±6 g/L, TS = 33±5 g/L, VS = 26±2 g/...Read more
The effect of HRT in the successful bioaugmentation of CSTRs working under ammonia toxicity
Tzenos C., Christou M., Kalamaras S., (Corresponding) Kotsopoulos T.
Topic:
Environmental biotechnology and bioenergy
High levels of ammonia is a common inhibitory factor in anaerobic digestion (AD) resulting in low methane production and unbalance of the process. In the present study, the adjustment of the hydraulic retention time (HRT) and the bioaugmentation process (BP) are investigated to counter the negative...Read more
One-stage and multistage anoxic/oxic systems based on continuous plug-flow anammox process for mature landfill leachate treatment
Ren S., (Corresponding) Peng Y.
Topic:
Wastewater treatment
As a promising biotechnology, the anammox process has been increasingly investigated for landfill leachate treatment. However, its application has been limited by the long generation time of anammox bacteria (AnAOB) and insufficient nitrite supply in actual projects. To overcome these obstacles,...Read more
