Salinity tolerance is one of the most important factors for the application of bioreactors to high-salinity wastewater. Although marine anammox bacteria (MAB) might be expected to tolerate higher salinities than freshwater anammox bacteria, there is little information on the effects of salinity on MAB activity. This study aimed to reveal the nitrogen removal properties in a continuous MAB reactor under conditions of rapid and extensive salinity changes. The reactor demonstrated stable nitrogen r...

Partial nitritation and anammox (PN/A) was applied in a lab-scale membrane bioreactor (MBR) to investigate its technical feasibility for treating ammonium-rich wastewater with low C/N ratio. The bacterial community was analyzed by molecular cloning and 16S rRNA sequence analysis. Partial nitritation (PN) was first realized in MBR by seeding aerobic activated sludge. With dissolved oxygen control, a steady effluent mixture with NO2 −-N/NH4 +-N ratio of 1.13 ± 0.08 was generated from the PN proces...

Abstract Groundwater level simulation models can help ensure the proper management and use of urban and rural water supply. In this paper, we propose a groundwater level tank model (GLTM) based on a conceptual rainfall–runoff model (tank model) to simulate fluctuations in groundwater level. The variables used in the simulations consist of daily rainfall and daily groundwater level, which were recorded between April 2011 and March 2015 at two representative observation wells in Kumamoto City, Jap...

Kumamoto City that has a population of 0.7 million depends on the only groundwater for the drinking-water demand. Recently, there are growing concerns about a groundwater contamination by nitrate. In this study, we aimed to reveal the situation and cause of nitrate contamination of groundwater in Kumamoto City and its neighbouring area by a combination of water-quality measurement and the analysis of public data. Nitrate concentration in the groundwater varied according to the area-location, how...

ABSTRACT Groundwater level is a major parameter in quantifying groundwater resource. Application of simple tools to simulate and predict groundwater levels is an important issue in groundwater hydrology. Tank model is a simple and useful conceptual hydrological model which is capable to simulate different system states without considering complex hydrological structure. The Shuffled Complex Evolution-University of Arizona (SCE-UA) algorithm is an efficient automatic calibration algorithm in sear...
